What is single ply roofing?

Single ply roofing are roofing materials that are specially made for low sloping or flat roofs. They have prefabricated detailing accessories which makes installation easier with wide width sheeting. They have fewer seams than asphaltic rolled roof systems and won’t require any torching or hot asphalt for installation.

What are flat roofs called?

Flat roofs are also known as low-slope roofs and are commonly found with commercial properties around the world. According to the National Roofing Contractors Association a low-slipe roof is defined as having a slope of 3-12 inches of less. 

Which roof type would a single ply roof membrane be installed on?

Single ply roofing is ideal for low sloped and flat roofs. Mechanically fastened single ply roofing can be used on all types of slopes without limitations and are preferred for hurricane prone areas. 

What is single ply membrane made of? 

Single ply roofing can be made of a variety of materials yet is predominately composed of synthetic polymer. These roofing materials make the membrane flexible yet strong. Single ply roofing can range in thickness from 1.1mm to +2mm. While some products are homogenous others are reinforced with glass fiber or polyester depending on the application.

What is the difference between TPO and EPDM roofing?

With single ply roofing, the difference between TPO and EPDM roofing are as follows. EPDM  will have a dark surface while TPO will have lighter colors. TPO will therefore be ideal for cooling the building down as it will reflect sunlight allowing commercial HVAC systems to work less and use less energy. TPO will also have a higher resistance to punctures than EPDM.

Do you need ventilation with breathable membrane?

Breather membranes are installed on the outer side of insulation over or under the counter battens on a pitched roof. They allow water vapor to escape from inside a building. This often means there won’t be a need for ventilation. 

How do flat roofs drain water?

A flat roof will be able to drain water with an interior system of pipes which can be found below the roof in order to carry water away from the foundation. Drains are placed in the center of the roof typically and the pipe system is protected by the roof and walls of the building which lowers the pipes’ risk of cracking, bursting, or freezing. 

What is the best way to stop a flat roof from leaking?

The best way to stop a flat roof from leaking is to have a rubber membrane or roof coating applied to the roof. A flexible membrane will prevent any punctures from forming and thereby any leaks. A roof coating can repair minor issues with your roof including covering leaks of a certain size.

How long does single ply roofing last?

Single ply roofing materials will last longer if properly installed and maintained at around 30 years. It’s important to conduct yearly inspections to make sure there aren’t any problems with water pooling, too much debris covering the roof, punctures, cracks, leaks an other issues that may befall your roof. With a yearly inspection you may be able to catch problems in their minor stages before they escalate to larger issues. That way you can get spot repairs and have your roof be able to reach the end of its natural roof life before full on replacements become necessary.

Are aluminum roofs good?

In general, metal roofing systems are a popular choice for commercial structure roofing, with aluminum being the most popular of them. It has a lifespan expectancy of thirty years or longer, it is lightweight and has a high reflectivity, which is excellent for areas where the summer sun can heat a building quickly. For commercial structures on coastlines where the sea air can be an issue for metal, aluminum roofing is resistant. 

The Washington Monument cap was the first time aluminum roofing was used in 1865 when aluminum was separated from bauxite to manufacture one of the building grade types. 

Today, all-aluminum roofing systems are pre-painted and comes in almost any profile. Aluminum roofing is mostly made from recycled material today, between 90% to 95% is used beverage cans. These are reasons that make aluminum roofing one of the best green roofs for a commercial structure.  

Which metal roof is best?

Metal roofing systems are a popular choice for commercial building roofing material and have been for the last fifty years or longer.  The location of the building can determine the choice of which metal roofing material is the best. 

• Aluminum 
• Copper
• Corrugated galvanized steel
• Metal Sheets
• Stainless Steel
• Standing Seam Metal
• Blended aluminum, silicon-coated steel, and zinc

As we’ve mentioned here, aluminum roofing is a better choice for commercial structures on seaside coasts because of the better sea air resistance. 

Which is better steel or aluminum roofing? 

 When comparing steel vs aluminum roofing, both are excellent for commercial metal roofing purposes, each having their strength. The benefits that aluminum roofing can offer you for roofing a commercial structure are: 

• Extremely resistant to corrosion  – steel is more susceptible to being damaged by seawater over time. Aluminum roofing material I warrantied for coastal areas – steel is not.
• Aluminum is lighter weight making it more flexible – steel is heavier weight and more rigid.
• Aluminum roofing has a better strength-to-weight ratio than steel
• Aluminum roofing doesn’t store as much heat and cools faster than 
• Aluminum roofing is not Class A fire-rating without proper underlayment and sheathing

Does having a metal roof lower your insurance?

It can base on what type of metal roofing you have installed.  Steel is Class A Fire Rated in its standing; however, aluminum roofing is not Class A Fire Rated unless installed with a correct level and type of insulation. Roofing is an investment for any commercial building, and you need to go with the best material for your budget and structure.  Aluminum roofing is worth talking to your roofing contractor and doing your research before choosing one type of roofing material over another. Call 412-256-8050 today for your legal needs.

As we mentioned earlier, if the insurance company determines that the leak was in existence and ignored, your claim will be denied.  Ask your roofing contractor about a regular maintenance plan is a great commercial leak detection way to prevent those denied insurance claims. Here, we offer you a few commercial leak detection steps that will indicate you need to get a professional commercial roofing contractor on the job immediately: 

• Ceilings or Walls Stained – No matter what type of ceiling system your commercial structure has, when there has been an extended exposure of water to the roof by way of a leaking roof, it will eventually discolor the ceilings. The same is to be said about walls that are adjacent to the ceiling where the roof is leaking.  Even worse, stained walls can also mean the roof leak has found its way down inside the walls, creating more damage.   
• Standing water – A walk around your commercial flat roof that finds standing water would indicate the drains are clogged. The water has nowhere to go, so it ponds and puddles.
• Alligatoring or Blistering Membrane – A flat roof membrane is only good for so many years, and after a while, it becomes aged and weathered from the UV rays and weather. They blister, bubble, and crack, then the ponding water gets in those areas and make their way to the inside.
• Loose seams – Some flat roofs have membrane with seams. As the roof ages and becomes weathers, those seams will loosen and come apart.  This allows a place for that ponding water to enter, making its ways inside the building.
• Holes or tears in the membrane – This can happen from high winds dropping things on the roof or from service technicians walking around on the roof.  Another reason routine inspections are recommended, allows you to catch these things and get them repaired before they become a problem.
• Flashing damaged – High winds and temperature contracting and expanding the metal flashing around the roof of your commercial building can cause that flashing to loosen and come off. 
• Odor and Mold – There is no better commercial leak detection for a roof than noticing a foul odor of mildew or mold in any part of the building. Moist environment grows mold and if there is roof leak, your nose can be your commercial leak detection system. Ignore the odor and that mold will keep growing, making your employees sick and keep your customers and visitors at bay.
• Puddles In The Building – If there is water dripping from the ceiling or there are puddles in the middle of an area, that is an obvious indication you have a leak of some sort inside your commercial roof system. It isn’t necessarily a roof leak though, as it could be the HVAC or plumbing system. Having your own maintenance team do the regular inspection. Acting as a commercial leak detection system, they will know when they see an issue with the HVAC, the plumbing, or if there is a potential roof leak. From that observation, they can advise you what type of professional contractor to call and get the matter resolved quickly. 
• Increased Energy Bills – A roof leak will allow the insulation to get saturated before it gets to the ceiling tiles. This is going to make that insulation less effective in keeping your building cool or warm as needed, and that will cause your energy bills to increase. 

What causes a leak in the roof? 

There are several possible commercial roof leak causes, many could be caught and repaired before they became a leaking problem with regular inspections by your maintenance staff or a commercial roofing contractor. Causes that a commercial leak detection find are common with commercial roofing leaks: 

• Drainage: When a commercial roof is installed, the builder will take into consideration how it will drain. There should be multiple points of draining based on possible vulnerability like downspouts, drains, gutters, and scuppers. If these are not cleaned regularly, they can become clogged and unable to drain.  The water backs up, pond and puddles, seeping its way into the building. 
• Penetrations: Most commercial flat roofs have penetrations for drains, gas lines, HVAC units, plumbing, vents, etc. If the boots that seal these up have become dried and worn, this create a vulnerable place for leaks. 
• Roof Flashings: f the roof flashing that joins areas on the roof like the chimneys, interior walls, roof edges, and skylights comes loose or isn’t installed correctly, water can seep in those areas and being leaking into the building.   
• Membrane: A commercial roof needs a membrane that is waterproof and if that membrane becomes damaged, or has gotten old and isn’t replaced, it allows water to penetrate to the inside of the building. 
• Old Roof: A commercial flat roofing system should have a lifespan up to 20 years. This can vary based on the maintenance and upkeep of the roof, the climate, and the environment.  If your commercial building roof has reached the 15 year mark, it is time to have a professional roof inspection performed, this will include having commercial leak detection done, and they can advise you if the time has it replaced or how much more life your roof has left. 

How do I stop my roof from leaking? 

Roof leak and roof damage is not something any commercial building owner wants to deal with, but when it happens, you don’t have a choice.  If this happens, hopefully, you have the manpower and equipment to get on the roof and patch the leak temporarily with roofing tar and a piece of plywood. Using a trowel on the underside of the roof, spread the roofing tar in and around the leak. Push the piece of plywood into the tar and, using the trowel, spread more roofing tar along the edges of the wooden patch. 

 Get several quotes and compare them before making a decision to repair or replace, but don’t assume the cheapest is the best, nor is the most expensive. Dial 412-256-8050 today for your leak repair in Pittsburgh, PA.

Do Cool Roofs work?

A cool roofing systems delivers higher solar reflectance in comparison to standard roofing. A cool roof reduces the air temp, lowers the demand for power during peak hours, which can help ease possible power outages. Plant emissions power is reduced, and a higher thermal emittance. With the reduction in needed power, the emissions, carbon dioxide, nitrous oxides, sulfur dioxide, and mercury are reduced too.

How much does roof color affect internal temperature?

Light colors will reflect the UV rays of the sun, deflecting the heat which keeps the interior cooler. Dark colors absorb the heat of the UV rays, keeping the higher the temperature on the upper part of the structure. This is where ceiling fans come in handy. A cool roof is designed to diminish heat absorbed in the roof and can lower the temperature of the interior by 50 degrees.

What color roof is the coolest?

Dark colored roofs can make a 95 degree day feel like 150 degrees on the roof, and that heat penetrates to the interior. A dark roof only reflects around 20 degrees of the UV rays. This is why a cool roof is traditionally white, which reflects over 50 percent of the heat generated by UV rays. An additional benefit of the lighter cool roof is the energy savings by taking less work off the HVAC system. 

Cool roofing can provide your business with energy efficiency during those hot months. Call 412-256-8050 today for cool roofing information and installation in Pittsburgh, PA.

What is the Best Commercial Roofing Material?

In a general sense, the best roofing material is dependent on the kind of business it is implemented on. For roofs that have an incline, metal roofs tend to be the roof of choice that lasts the longest and takes the most from the environment. Accordingly, the superior flat roofs tend to be made from OVC, TPO, and modified bitumen. Other suggestions for both include: 

• BUR or built-up roofing 
• EPDM
• PVC

Each roof respectively has its own advantages to offer the business owner while generally being more accepting of improvements over their residential counterparts. Roof restoration in this regard can be used to keep the roof of any mentioned kind going longer thanks to the materials that it is built out of. Commercial roofs are generally built up of materials that can be easily repaired and maintained in the long run. When restored, the special coating applied at the end of the service reflects sunlight and offers another layer of resistance to other weather patterns. It also applies to the parts of the roof like flashing, nails, and can serve as an easy way to patch minor leaks.

How long should a Commercial Roof Last?

When considering a roof, lifespan tends to be one of the deciding factors in the decision-making process. There is also the factor of how long things like nails, sealants, and other facets of the roof last while keeping your business safe from the elements. As it pertains to the roofs listed above, one can reasonably expect such a timespan as:

• Metal Roof: 30 to 50 years
• OVC: 35 years
• TPO: 22 to 30 years
• Modified Bitumen: 20 years
• BUR: 15 to 20 years
• EPDM: 20 to 30 Years
• PVC: 20+ years

When it comes to built-up roofing, a roof tends to last up to when its granules stop being effective at which point it begins to break down and needs a restoration of its top layer. However, when it comes to metal or other slanted roofs, the nails and sealants are of particular importance. Sealant lasts a commercial business owner about ten years before needing reapplication of the coating. Both the level of the thickness the coating is applied and the weather of the area tends to play a factor in how long that pertains to. How you can catch a roof degrading in its parts, layers, or anything else is to get an inspection by an experienced roofer. We at Great Lakes Commercial Roofing can help with that.

Living in Pennsylvania, no matter if it is in Pittsburgh or throughout the State, offers its own unique set of experiences and challenges.

This is especially true for commercial business owners. This is because their roofing systems need to stand up to a specific set of circumstances and need to remain durable yet flexible. Most of all, it needs to be able to do that when the weather turns and the climate gets cold, cold, cold.

Perhaps your business finds itself in need of a completely new roofing system. This can be due to damage to the old system – rips, tears, holes, leaks, and a plethora of other things – or it can just be that the current roofing system is well past its age and needs to be swapped out with a new one.

Knowing what to expect when getting a new commercial roof in Pennsylvania is important so that you can get the proper roofing system for your needs. A new roof is too large of an investment to go wrong choosing the type and this guide will be what you need to know what to expect when searching for a new roof.

Roof Size

Obviously, the first thing that you need to know is exactly how much square footage you are dealing with. If you have a larger roof, it makes sense that the installation costs will be much higher than they may have been for a smaller roofing system.

Keep this in mind if you think that replacing the roof entirely is something that needs to be done. Your budget will have to adjust for the size (and cost) of the larger roof, so it may wind up being in your best interests to go with a repair or perhaps a reinforced membrane that can go over the top.

It is also important to know the size of the roof because this is not something you can tackle a little at a time. You have to do the entirety of the roof or none of it at all. This is because not giving the entire roof the same treatment can lead to parts of the roof being more vulnerable than others to different types of wear and tear.

Roof Layout

While the size is certainly important, the layout is just as important. This is because your roof may have a number of different ridges and surfaces that need addressing. Even if you have a flat roof, there are definitely things that need to be made apparent when looking into changing out your roofing system.

If your roof is more complex – containing more ridges, vents, and other surfaces, it will take a lot more time and effort on the part of the roofing contractor to get the job done. Keep that in mind as well when determining the costs involved.

Most quality contractors will come out to your commercial property, assess the roof, and give you a quote as to what the entire process will cost. This will give you a better idea of the sort of financial undertaking that you will have facing you when replacing your current roofing system.

Roofing Materials

This is arguably the biggest determining factor in what it will cost to have your roof replaced. Depending on what you go with, the costs can be relatively low per square foot or they can be quite expensive. It all depends on the level of durability that you are looking to get out of your particular system.

Flexibility in roofing material is important as well. Flexibility is more important in an area with colder climates like East Pittsburgh because those materials will constantly expand and contract as the weather shifts. This can lead to additional wear and tear on the roofing system that can lead to earlier repairs or replacement.

Asphalt shingles are the most commonly used roofing material that there is for commercial roofing. This is because the installation is relatively cheap and easy and they are able to provide reliable, sturdy, durable coverage to your roof.

Depending on the kind of asphalt roof that you go with, the seams that are in the roofing system can be completely waterproof, keeping your roof from dealing with those nasty leaks that can really become a problem for both the roof and the rest of your building.

For flat roofing, there is a modified bitumen roofing system that provides seamless installation. This keeps the water out across the entirety of the roof and limits the chances of things like puncture due to foot traffic.

Depending on the kind of bitumen roof that you get, some are even capable of offering UV resistance. This means that the sun’s rays won’t penetrate the roof, heating up your building in the process. When this is the case, it means that your building is better able to regulate its temperature without help from the HVAC system. That can run up your energy costs substantially.

Lastly, there is the option for clay tile but it is very expensive to install as in $16,000-$25,000 for 1,500 square footage. Clay is meant to last an extremely long time but the upfront investment is substantial, so keep that in mind.

As always, ask for a quote before agreeing to anything. This will give you a better idea of not only what each kind of material would cost but which roofing professionals would be the best option for finding a new roof at a cost-effective price.

Roof Pitch

Generally speaking, if you have a steeply pitched roof, the costs will be greater for the project. With a flat or low steeped roof, you’re not having to put more time into it. A steeply pitched roof is more difficult to walk if it is walkable at all and comes with a far greater cost.

There is also a higher risk when installing shingles on a steep roof because the costs will be substantially higher than a traditional low steep or flat roof. Ultimately, there are a number of factors that need to be weighed when it comes to getting your roof done and there are things that you may not have even considered along the way.

Roofing Layers

Multiple layers on a roofing structure means that multiple redundancies are in place. What does this mean, exactly? It means that should one of the layers become compromised – ripped, punctured, peeled, cracked, etc.  – that there are other layers to pick up the slack.

This means that should any of the roofing layers fail, the roof will still do its job. It is recommended that you replace that damaged or destroyed layer of roofing membrane, but it won’t require immediate or emergency attention that can lead to greater costs.

But keep in mind: the more layers there are on your roof, the higher the costs will be. This can be exacerbated if there are old layers of the roof that need to be removed in order to install the new roofing. This means higher labor costs as well as dumping fees for disposing of the old layer of roofing system.

The number of layers will likely be determined by the material that you are using and the life of the previous roof. If your area is prone to more inclement weather, it would be wise to go with something a bit stronger and longer-lasting in nature.

Labor

Labor costs can depend on a few different things. Your area will likely have several different options when it comes to roofing contractors. Keep in mind that the skill and availability of that roofer will likely dictate the cost.

Don’t immediately cheap out on labor. The old saying goes “you get what you pay for” and the cheapest possible labor can lead to subpar work that will only need to be corrected later on down the line. Keep that in line when looking at your roofing budgets.

Final Thoughts about Local Commercial Roofing

It should go without saying that your roof is essential to your commercial business. If anything goes wrong, it can not only mean a substantial cost to you to have it repaired but it can lead to service or production interruptions that can have an impact on the bottom line as well.

In Pennsylvania, where the summers are very hot and the winters very cold, it is important to make certain that your roof can stand up to the wear and tear that the changing of the seasons brings on. This is in addition to high winds and storms that may strike the area.

Your roof will go through a lot in a more inclement location like Pennsylvania. Make certain that you get the roofing system that you need to keep the weather at bay and keep you from having to replace your roof in short order.

Great Lakes Commercial Roofing has you covered. Your investment will keep your roof protected and your business humming without having to worry about what kind of damage could lay ahead. That is an important peace of mind to have.

When your Pittsburgh commercial building roof begins to fail, it can be either plainly obvious or so subtle that you may not initially notice it. A lack of awareness can lead to further damage to your roofing system like leaks; these leaks can spread into the rest of your building and cause further damage.

It would be more beneficial to identify these issues quickly so that you can have proper roof repairs implemented. But not being able to see those signs doesn’t change the fact that damage can be done.

So, what are some signs to look for when your Pittsburgh commercial business roof is beginning to fail and needs repairs? After all, in Pittsburgh, the weather can be quite temperamental and lead to damages of all sorts like leaks and wind damage.

Roof Bubbles

If you happen to notice bubbles or blisters on your roof during a routine inspection, it could be a sign that the roof was improperly applied. Generally speaking, these bubbles or blisters can start out subtle and become more noticeable over time.

Bubbles are usually the result of moisture that gets trapped under the roofing materials. The water eventually evaporates and the result is the formation of those bubbles or blisters across your roof.

What’s really bad about having blisters or bubbles is that they can easily allow water to eventually seep through the roof. This can cause heavy damage to the building itself, leading to more costly repairs down the line. Keep an eye out on those bubbles; quick action can mean resolving the problem without having to implement substantial repairs or, worse, a complete replacement.

Sagging Areas

Flat roofs are meant to be level and even because the roof is built to handle a certain amount of weight, both per square foot and all across the entirety of the roof. If you do notice that areas of your roof are sagging, you should call in a professional service immediately.

In Pittsburgh, the sagging of your roof can be due to a number of different factors. Accumulated moisture is probably the biggest cause, especially when snow is involved (and in Pittsburgh, it can be involved). You can help prevent sagging by clearing your roof whenever there is a buildup of moisture or snow.

There can also be an additional weight that is put on if new roofing materials are laid down over the top of the old ones. While that might seem like an easier method of installation, you should always keep in mind that the roof is constructed to handle a certain amount of weight and that roofing system will only be adding more weight to the mix.

Moisture Infiltration

This is perhaps one of the most foolproof ways to confirm that your roof is having issues. You will see signs that the interior of your building has been dealing with something like a leak because there will be water soaking into areas of the building, primarily the roof.

Some of the most common signs are things like water stains on the ceiling or perhaps water dripping down the walls in a hall or corridor. These are the most obvious of issues and may not always be there.

Sometimes it can be far more subtle things. If you notice that there is a musty, damp smell coming from the roof, that can be indicating sign that things are wrong with your roof. When you do notice these signs, it is important that you not ignore them.

Acting quickly when you notice a leak in your roof can help you get the repairs that you need to be done to extend the life of your roof and protect the rest of the building as well. Ignoring leaks can have a potentially catastrophic result, so do not ignore leaks should you notice them.

Seaming Gaps

The vast majority of roofing systems will require seams that connect the waterproof materials together over the roof’s decking. There will be times that water will be able to make its way through the seaming and manage to soak into the roof.

This means that you may have to assess the seaming of your roof to make sure that there are no gaps that could be compromised. If you do notice any gaps or aren’t sure if those gaps exist, it might be in the best interest of your roof to call in a professional.

These gaps are what give the roof its waterproof integrity and if they are compromised at any point, so too are the waterproof qualities of your roof. When this happens, your roof is much more susceptible to water damage. This means potentially costly repairs down the line that could have been avoided otherwise.

Clogged Drains

This is one sign of roof damage this is often overlooked. If you happen to notice that the volume of water coming from the exterior downspouts is not what you might expect based on the amount of water landing on your roof, this could be a sign.

Check out the roof and look for any signs that your drain is clogged or that water has been collecting on the roof. If you leave ponds of water on the roof, it will eventually lead to the deterioration of the insulation layer.

When that pooling happens, it means that the water will eventually soak into the roof itself and cause substantial damage, potentially to other areas of your commercial building. It cannot be understated: do not let water damage to accumulate on your roof because it can do substantial damage to the rest of your building.

General maintenance and bi-annual inspections can help keep those drains working optimally, keeping your roof free and clear of water buildup that can lead to serious damage.

Failed Flashings

Flashings are one of the most important components of your roof. This is because they are used to create a sealing between the areas that join your roof with other structures like a chimney or vent. Those flashings can also be used where two different roofing materials meet and the angle does not allow for the overlapping of those materials to be used as a seal.

If the flashings on your commercial roof have been poorly attached, are deteriorating, or missing entirely, it could be a clear indication that there is something wrong with your roof. Depending on the issue, it could potentially wait for a little while, but it is recommended that you don’t let it sit for too long.

Should your flashings be damaged or missing, it can lead to water infiltration. Don’t hesitate to call a professional roofing service if you do notice these things as infiltration of water can lead to substantial damage to both the roofing system and the rest of the building.

Aging Roof

While there is definitely a litany of other signs to be aware of when it comes to the health of your commercial roof, sometimes it just comes down to the simple fact that your roof is on its final legs and has seen more than its fair share of wear and tear.

It can be difficult to know precisely when your roof is too old, but if it is 25 years old or more, it’s probably a good idea to think about replacing the roofing system entirely. Even under optimal conditions, a roof will have sustained substantial wear and tear throughout the years, meaning it only has so much life left in it.

It is a good idea when purchasing a commercial building that you have the roof inspected. Even if the previous owner says that the roof is in optimal condition, an inspection will verify that assessment and ensure that your roof is working optimally.

Final Assessment

Being able to see damage to your roof is a difficult thing to do from the ground. It is never advised that you get up on your own roof as too many things can go wrong for those without the proper level of experience.

The best course of action is to call in a professional inspector to take a look at your roof at least twice a year. This will keep you on top of leaks, cracks, breaks, damaged seams, and all the other things that lead to roof damage.

Preventative maintenance is a good rule of thumb in just about any scenario but it is especially recommended when it comes to a pricey investment like a roof. If you don’t pay attention to it, the damage could occur and be allowed to persist for far too long.

Instead, invest in a couple of inspections per year so that you can stay up to date on repairs when they need to take place. This might cost a little in the short term, but it will likely save you a ton in the long run because it will keep those costly repairs at bay.

When it comes to your commercial roofing system, especially in an inclement climate like Pittsburgh, a little care can go a long way.

Is a metal roof loud when it rains?

Not any more than an asphalt roof! Surprised? Yes, at one time, commercial metal roofing was as noisy as the metal roofing on your grandpa’s barn. Today, though, commercial metal roofing isn’t installed over the building’s roofing surface. That leads to the question, so How do you install metal roofing then?

Today, when commercial metal roofing is installed, strong sheathing goes on first, and if there is an existing roofing surface, they install the sheathing first. This reduces the noise from hail, rain, windblown debris, and other things that would typically make a loud noise on any residential or commercial metal roofing. In fact, it can sometimes be even quieter than other roofing materials, especially asphalt roofing.

Another myth about metal roofs is the lack of energy efficiency and sturdiness. So, yes, if you have been in an old metal barn during the winter, it is cold, especially if the wind is blowing hard and strong. Today’s commercial metal roofing isn’t like that, and that is mainly because of how it is installed – the sheathing.  The sheathing that is installed first does a lot for making a commercial metal roofing quiet and making it energy efficient and strong.

What do you use to seal a metal roof?

If it is a brand-new commercial metal roofing is installed, or you’re having an old one restored, you need to know that it has suitable water penetration protection. Metal roofing comes in panels and an experienced, professional roofing contractor will attach those individual panels to each other by snapping them together using rubber grommets, fasten them to the roof decking.

If this is a new commercial metal roofing, they use butyl seam tape or other types of metal sealer on the joints and seams where the metal panels meet. It is also applied over any fasteners that well that butyl caps to ensure good sealant.

With a commercial metal roofing restoration project, the fasteners, joints, nails, and seams are prone to dilapidate with rust which allows water to penetrate, as such, thorough re-sealing with new metal roof sealer is needed. Experienced commercial metal roofing contractors will use butyl tape, butyl caps, or some other approved metal roofing sealant on these detailed areas.

After installation of the metal roof sealers is complete, and any rust has been primed or removed, a base coating is applied, sometimes with customized reinforced polyester fabric is placed in areas that need extra strength. Then a topcoat is applied, leaving a fully restored commercial metal roofing that is UV protected and is waterproof. 

What is the best color of metal roof for energy savings?

Commercial metal roofing can be fifty to sixty degrees cooler when you go with a light color like beige, blue, light bronze or light green, peach, or white. The hotter the climate, the lighter the color is recommended by roofing contractors.

If metal roofing sounds like something you want on your commercial building but you’re not sure where to get started, the Internet will give you listings of roofing contractors. Type in the search bar, “Commercial metal roofing near me” or “Commercial metal roofing contractors near me”, and you’ll probably get 100s to choose from.

Get written quotes from 2 to 3 different ones and compare them to each other.  Remember, cheaper is not necessarily the best, even if your budget is tight.  It could end up costing you twice as much later.

How Long Do Foam Roofs Last?

According to national estimates, a foam roof is reputed to last approximately twenty to thirty-five years. Of course, this estimate depends upon proper maintenance, the prevailing weather patterns of the area, and foot traffic.

What is a Foam Roofing System

Foam roofs are designed to be a reliable roofing system that is safe, seamless, and walkable. Spray polyurethane foam is used to seal the roof against leaks. Foam roofing is remarkable because it easily bonds around vulnerable roof perforations. These roof perforations include pipes, vents, and edges. With foam roofing, the roof surface is built up in certain areas to prevent heavy standing water from developing.

Is Foam Roofing Good

Foam roofing has a number of advantages and disadvantages. In order to understand more about his roofing material, please make sure to review the following bullet points.

• Great insulation properties. The suspended aluminum particles in the foam reflect UV rays.
• Waterproof. Foam roofing has unique waterproofing qualities. The closed-cell foam is apparently the only insulating material that does not soak up water.
• Flexible. Foam is particularly interesting and beneficial because it can be applied to both new and old roofing projects.
• It provides structural integrity. Something that is truly interesting about polyurethane foam is that it is able to withstand the expansion and contraction that occurs over time. Foam roofing can also withstand very high winds and many natural weather elements. 

What is Spray Polyurethane Foam Roofing

What is the coolest roof material?

If you must install a new roof on your commercial building, the choices can confuse and overwhelming. There are many roofing materials types for commercial buildings, which one is the best all-around choice for cool roof purpose?  Here, we are listing 4 different roofing materials with the pros and cons of each, and which is the best for a cool roof result. 

EPDM (ethylene propylene diene monomer) 

EPDM roofing is commonly referred to as rubber roofing and is a common choice among commercial buildings because it is the least expensive of all options. It is lightweight, making it easy to install and doesn’t require the roof decking to be reinforced. This is a durable material that won’t scratch or scuff and has a life expectancy of a high-quality EPDM roof is 20 years.

EPDM is a black material and perfect for absorbing heat without being easily damaged by the sun’s UV rays. This makes a good product in colder climates, but not a good option for cool roof purposes.  EPDM is not aesthetically pleasing though with an inner tube look when rolled out. If your commercial building is a warm climate where the sun’s UV rays can heat a building up through the roof, this is not the material you need. It is not a cool roof material and can put a lot of strain on an HVAC system.

The drawbacks to EPDM are few but should be considered. It is also easily punctured by hail, tree branches, or a service technician that needs access to HVAC or plumbing pipes and vents found on commercial building roofs. It is easy to repair, but any puncture not noticed will allow water to infiltrate, leaving the possibility for major problems. It is installed with bond seas and if those seams are not placed right and the EPDM material doesn’t adhere well, water can infiltrate underneath the membrane.

TPO (thermoplastic polyolefin)

TPO is a popular option for commercial building owners because is inexpensive to install, even less than the previously mentioned EPDM roofing material. TPO is good for cool roof a white color that reflects the sun and minimizes the heat buildup inside a commercial structure, which is perfect for hot weather climates. It is lightweight and with several options for installation, makes it popular among roofing contractors.

It is resistant to breaking down, corrosion, algae growth, and mildew. With TPO, maintenance is minimized because pressure washing isn’t necessary. The seams are heat-welded, creating a bond that is more dependable between the seams, which is where most commercial building roof leaks begin. 

The drawbacks of TPO roofing start with the quality variances. Each manufacturer has different standards, which is why roofing contractors will always recommend going with a well-known brand name. The thickness of this material can vary also, which can lead to consistency problems, TPO’s top layer is a laminate, which can have weak points that cause cracking, crazing, deterioration, and shrinking. A major consideration for commercial business owners should be that TPO is not fire-resistant.

PVC (polyvinyl chloride)

Two layers are used to create a PVC roofing material with a reinforcement of polyester in between them. These layers have additives that make it flexible and UV-stable and prevent curing. It is durable, lightweight, and is fire resistant and resistant to chemicals and wind. Because it is heat-welded during installation, the sheets are permanently bonded at the seams. 

The biggest drawback is the expense. Over time, PVC shrinks, lifting the corners and pull the seams, which can lead to leaking. PVC is not the best for cold weather climate because it is prone to puncturing and shattering as its ages, which can be hard to repair. PVC has strong similarities to TPO but PVC has an upper hand with stronger resistance to chemicals and punctures.

SPF (spray polyurethane foam)

SPF roof coating starts off in a liquid form and is transformed into a solid as they apply it, expanding as it dries. This is a good roof coating for sustainable cool roof energy savings when applied in multi-layers with an acrylic roof coating. It is durable and strong, and the reflective topcoat makes it the cool roof coating a commercial building owner wants.

Proper maintenance and reapplying coating regularly, an SPF roof will last over 40 years. Because it seals cracks, crannies, and gaps, it makes airtight, cool roof and waterproofing systems. SPF roof coating is a good cool roof material because it provides a commercial building layer of insulation that saves on A/C and heat costs. 

This lightweight material will self-curb around protrusions and is often used to correct ponding water. The downsides to SPF roofing are the chemical reaction it has between two liquid compounds. With careful applications, it makes a good material, but careful calibration is needed while applying it.

What type of roof will last the longest?

By far, concrete, metal/steel, slate, or tile roofing materials last the longest of all materials used. Research finds these to last 50 years or longer. Next in line of lifespan, Built-Up roofing, asphalt shingled roof, or single-ply roofing, each estimated to last up to 30 years, depending on the climate and environment of the commercial structure. They estimate it a foam roof to last 25 years or longer while wooden shakes & shingles have a life expectancy of fifteen to twenty years.

It depends each on the climate and the environment and how they are installed and maintained. Manufacturing can affect longevity as well with each manufacturer having different procedures.

What color roof is the coolest? 

Dark color roof surfaces absorb the UV rays and the heat generated from those rays. For the typical flat or low slope roof on a commercial building, a traditional cool roof is all white, reflects the solar rays by as much as 50 percent or more. The use of colorants or pigments can create a nonwhite cool roof that will reflect the sun’s invisible, near-infrared radiation.

The benefits a commercial building we have from installing a cool roof system are many. Here are the main ones:

• Air conditioning needs are reduced, thereby reducing energy bills
• Non-air-conditioned areas are cooler with a cool roof
• Roof temperatures are decreased, extending the roof lifespan

A cool roof will do more than just cooling the commercial building. The environment benefits from a cool roof as well, especially in densely populated urban areas.  Which is better, a cool roof vs green roof?  A cool roof will remain cooler during peak temperatures. However, a green roof will have a longer lifespan, thus giving you more ROI for the initially higher costs for installing it.
