• Purer air. In a green roof, plants filter particulate matter from the air and convert CO2 into oxygen. The varieties of plants found in a green roof contribute to air purification.
• Reduction of ambient temperature. Plants absorb sunlight – fifty percent of sunlight is absorbed, and thirty percent of sunlight is reflected.
• Extension of overall roof life. Green roofs protect the roofing material underneath from external influences such as the sun, wind, and rain. This can extend the overall life of your roof for sixty years or longer.

How Long Does a Green Roof Last?

A green roof option can last for up to sixty years with proper maintenance and care. In Europe, many green roofs were installed in the 1960’s. Based upon the available statistics, thirty to sixty years is not an unusual lifespan for green roofs. Every residence should experience great functionality from top to bottom, ranging from one’s roof, to one’s underground pipes. Commercial plumbing needs for residents in Pittsburgh, PA should be streamlined and professional.

Do Green Roofs Need Drainage?

All roofing systems require excellent drainage in order to ensure the longevity of the roofing structure. This is especially true for green roofs. Series of layers of roofing material are engineered to thoroughly drain the rainwater properly. These layers are comprised of substrate, a drainage layer, and into the drains for stormwater or rainwater collection. The growing substrate layer must be kept separate from the drainage layer with a filter sheet.

Green Roof Issues

While green roofs boast a huge number of advantages, particularly for the environment, it’s important to consider some of the disadvantages. To begin, green roofs are more expensive than traditional roofs. Another thing to keep in mind is that green roofs are heavy. This translates to increased weight on your overall structure. Make sure that your current structure is strong enough to withstand a heavier roof. Green roofs also require extra maintenance. This is because you will need to provide a little oversight to ensure that your green roof remains a thriving miniature landscape. Treat it like a garden, and you will see it grow.

Why are Green Roofs Important?

Green roofs reduce energy costs by absorbing heat instead of attracting it. The natural consequence of this dynamic is that it provides natural insulation for buildings. This means that during hot summers, when air-conditioning bills tend to run high, a green roof can cut your energy costs by seventy-five percent or more. Green roofs present the ultimate roofing option for decreasing the production of greenhouse gas emissions, and purifying the air in your immediate atmosphere.

Are Green Roofs Sustainable?

If sustainability is the question, green roofs are the answer. A green roof significantly reduces the need for air conditioning in summer and provides insulation in the winter. Naturally, in the winter, the amount of moisture present in the drainage layers will impact the insulation of the building. Insulation is greatest in the summer, because the layers are dry, and reflect heat most effectively. Due to the reduced need for air-conditioning, a green roof significantly reduces energy consumption.

Green Roof Cost

Many experts claim that green roofs can not only save money, they can help alleviate the effects of global warming. Specifically centering upon the monetary cost of a green roof, there is a larger initial investment in a green roof. However, in areas that have extremely hot summers, there is the added benefit of the lower energy cost in the summertime, which can be one of the biggest energy bill drains. An exposed roof can get as hot as 158 degrees on a sunny day, while a green, shady roof can heat to just 77 degrees. The comparison is clear.

Green Roof Facts

There are a number of green roof facts to keep in mind whilst browsing for a green roof option.

• Stormwater management. In urban and suburban areas, large swathes of paved surfaces prevent stormwater from being absorbed into the ground. This excess runoff damages the prevailing water quality by sweeping pollutants into water bodies. Green roofs reduce the flow of stormwater from a roof by up to 65% and delay the flow rate by up to three hours.
• Biodiversity and habitat. A green roof can provide an excellent habitat for plants and animals, like birds and insects, and thereby increase biodiversity.
• Heat Island effect. Cities are warmer than rural areas due to the fact that concrete and asphalt absorb solar radiation. Green roofs are proven to reduce this effect.

It’s exciting to see the strides being made to improve buildings in a way that will help reduce costs while also benefiting the betterment of the environment! Building efficiency has a variety of categories that can improve energy usage and increase sustainability. If you’re in the process of a new construction or renovating an existing one, it’s important to consider the factors surrounding building efficiency improvements so both your business and environment can continue a symbiosis of green culture and practices.

What is building energy efficiency?

Building energy efficiency involves constructing new or renovating existing buildings in a way that significantly reduces the energy needed for various systems such as lighting, heating and cooling, water heating and other systems independently from the energy used or the equipment chosen for the building.

Why is sustainability important in construction?

Sustainability in construction means that resources are being used efficiently or in a way that considers the environmental impact and implications of the resources or process of construction used in a building. When constructing a building, there are already stakeholders of the client, firm and local government that can have a hand in a given project. However, it must be emphasized that the community and people in it can directly be affected by the decisions made and should be considered as additional stakeholders into the equation. Toxic waste could be generated from buildings as well as non-renewable energy sources which can produce a considerable amount of waste. It’s important to realize that it is very possible, and often cost-effective, to offset the harm we can potentially create in building by replacing them with beneficial paths that give more both immediately and in the long run.

How can buildings be more sustainable?

Buildings can be more sustainable in a variety of different methods, the possibilities are numerous! One can implement green commercial building materials, construction methods, techniques or even comply to building efficiency ratings!

Building Efficiency Ratings

There are certain building efficiency organizations available that provide guidelines for producing green or energy efficient buildings. They provide ratings in accordance to how far a building can go to achieve green methods. Here a few well known ones:

• LEED, which stands for Leadership in Energy and Environmental Design is an organization that offers rating levels that range from Certified, Silver, Gold and Platinum.
• The Living Building Challenge: uses seven performance categories known as Petals, which branch off into 20 Imperatives. Petals in turn hold categories of Place, Water, Energy, Health, Happiness, Materials, Equity and Beauty.
• WELL, also known as The WELL Building Standard, is a third-party certified by Green Business Certification INC or GBCI.

How can you improve buildings?

Here are a few areas that can be improved for building efficiency, some even offer a few examples that can be taken into consideration.

• Site Selection: have the building be placed in an area with already existing infrastructure to save on resources and money.
• Design: have the building meet LEED or other building efficiency organisational standards.
• Electronics, Computers, and Office Equipment: there are many Smart options out there as well as appliance brands such as Energy Star which offer energy efficient standards.
• Lighting
• Appliances
• Landscaping
• Renewable Energy Sources: grid tied solar photovoltaic panels can power lighting, appliances, hot water and heating and cooling systems. A small wind grid can be connected to your power provider or even off grid which can lower your electric bill by 50-90%. Micro hydropower can transform the energy of flowing water to rotational energy and finally electricity.
• High Efficiency Water Heaters
• Heating & Cooling Systems
• Ventilation: natural ventilation is the lowest cost option for energy efficient cooling of a building. Energy recovery ventilation in turn minimizes energy costs while providing controlled ventilation.
• Wall Assembly: s continuous layer of insulation (CI) around a building increases the R-value of the structure and rids itself of condensation. Structural insulated panels can save 50% of energy costs.
• Roof: metal roofs, cool roof coatings or even a Foam Roof (among other various options) can provide UV protection and resistance to leaks all while have life expectancy of at least 50 years!
• Water Efficient Plumbing: pex pipes don’t collect sediment build up and are more durable than copper pipes yet last just as long.

What are the advantages of green building?

• Health & Work Performance: Improvements in air quality can increase performance by 8%, employees in a green and well ventilated building show 101% increase in cognitive abilities and offices with windows can allow for an average of 46 minutes more of sleep.
• Reduced Costs:
  • Per business level: utility bills are significantly lowered, there are lower construction costs and higher property values for building developers.
  • Global level: energy spending can be reduced from €280-€410 billion ($313.6-$459.2)
• Increased Property Value: owners of green buildings have a 7% increase of asset value over traditional counterparts.
• Environmental: reduces greenhouse gases, energy and water consumption.

The fast majority of office buildings in the United States employ a flat roofing system, and for good reason. This durable roof structure allows businesses to save space and simplifies the process of making repairs (to a point). However, flat roofing systems also come with inherent challenges that can cost your company thousands of dollars if not addressed in a timely manner. This oh-so-important program of continued maintenance and repair can be difficult to manage, which is where a flat roof coating comes into use…

What are Roof Coatings?

Simply put, roof coatings form a small protective layer over your existing rooftop. The installation process is about as complex as spreading a couple coats of paint on your roof. Once spread over your roof, these coatings also work to mend small tears and punctures in the roofing material. On average, commercial-grade GAF flat roof coatings (or whatever brand you select) will last for approximately ten years. 

Which Roof Coating is Best?

There are a wide variety of coating products available on the market, but most commercial consumers prefer an elastomeric roof coating. Sometimes called a cool roof coating, elastic coatings provide a number of cost-saving benefits for your commercial roofing system. There’s the restorative properties we mentioned that can repair minor degradation in your rooftop. More importantly, these roof coatings prevent additional damage from occurring, such as:

• Impact damage from debris and hail
• Moisture degradation from leaks
• Natural corrosion from sunlight, water, and rusting
• Weakened material strength from UV radiation

The rubberized nature of elastomeric coatings enable your roof to absorb much of the impact force of hail without taking any serious damage. If you’re looking for maximum impact absorption, an EPDM rubber roof coating might be ideal for your business. Just make sure to ask your local roofer if your current roofing system will require a special primer before having your flat roof coating installed.

When it comes to stronger waterproofing protection, silicone coatings act as a flat roof sealant for your building. If you’ve ever suffered a roof leak at home or at the office, you know how frustrating the resulting damage and expenses can be. Ponding (pooling) water is one of the biggest difficulties that flat roofs have to contend with. When you install a silicone coating however, you’ll notice a marked improvement in protection against leaks. Unlike many other coating materials, silicone doesn’t chalk after prolonged UV radiation exposure.

Which Roof Coatings Provide the Best Energy Efficiency?

Generally, the most reflective coatings will generate the best energy savings. This light reflection also protects your rooftop from ultraviolet radiation, which naturally degrades almost all forms of roofing. If you’re wondering which roof coatings do this best, you’ll have a few options to choose from:

• Acrylics
• Urethane-Modified Acrylic
• Polyurethane
• Silicone

Acrylics provide excellent sunlight reflection and UV ray protection for a very affordable cost. While basic acrylic products don’t always perform well in circumstances with pooling water, they can be modified for stronger water-resistance. That’s where urethane-modified acrylics come in handy, as they feature stronger water and impact protection.

Polyurethane flat roof coatings are best known for their durability. They form a strong protective barrier against hail and other forms of impact trauma. Unlike other forms of coatings, polyurethanes endure foot traffic very well. White polyurethane products supply the best energy efficiency with increased sunlight reflection.

We’ve already talked about the benefits of silicone, so we’ll skip to a couple of frequently asked questions that relate to energy efficiency.

Does a White Roof Reflect Heat?

Yes! In the majority of cases, white roofing will reflect a higher percentage of sunlight. As a result, less heat penetrates the rooftop to impact the conditioned air in the building interior. By extension, rooms cool in shorter times, HVAC units can turn off sooner, and less energy is spent cooling the building. Of course, a fully functional cooling and heating system will also conserve energy and save you money. Don’t use a roof coating as an excuse to put off your American Standard gas furnace repair (or whatever hardware maintenance your building needs).

Can Elastomeric Roof Coatings Be Tinted?

Yes! In fact, many businesses like to have their roof coating tinted to another color besides white (for style purposes). This is great for rooftops whose color has faded from prolonged UV ray exposure. If you choose to have your flat roof coating tinted, it’s generally recommended to stick with a lighter color and retain your energy-saving benefits.

Ponding water is a problem that thousands of businesses face every year. It’s a treat that may lead to expensive roof repairs and even early roof replacement. As a business owner, defending your roof is an essential part of getting the most out of your investment. To help you, here is a quick guide on ponding water and how to prevent it!

What is Ponding Water?

Many, if not the majority of companies in the U.S. rely on a flat roofing system for protection. This style of roofing provides alluring space saving features and fast installation. However, flat roofing is particularly vulnerable to ponding water. As rain falls on flat roofing systems, those with poor drainage have a tendency to gather standing water. Unless this water is manually drained from the rooftop, it could stay there for days.

Just as putting off water line repair leads to major plumbing problems, ignoring water ponding on your roof can lead to dangerous consequences for your building. These consequences include:

• Damaged Paint
• Pests in the Stagnate Water
• Corroded Roofing Material
• Internal Leaks Beneath Your Roof

How to Fix Water Ponding on the Roof

So how do you prevent water from pooling on your rooftop in the future? First off, you need to ensure that your roof can drain properly. In easy circumstances, this may simple mean installing a drain pipe or two to allow rain to flow down from the roof. You might however, need a professional to adjust the gradient of your rooftop so that rain water doesn’t get stuck anymore.

Next, you might also consider installing a protective coating over your roof system. This is especially helpful for aging rooftops with a few cracks here and there, as the right coating will mend cracks and guard the roofing material from future corrosion. There are countless restorative coatings available on the market now; just make sure you choose one that’s waterproof!

Our commercial roofing systems are one of the best important parts of our building. Not only do they protect us against outside elements, they also keep our buildings warm or cool depending on the season. Because of how important they are, it’s essential to keep them in the best condition. The best way to achieve this is with a professional roof inspection by a certified commercial roofer. We recommend that our clients get a roof inspection twice a year, once in the spring and once in the fall. However, if a big storm has passed through Pittsburgh, we suggest that an inspection is completed to make sure the roof doesn’t have any damages. Find out what our commercial roof inspections entail!

What a Commercial Roof Inspection Entails

• Building Envelope Inspection: We always think its a good idea to evaluate the building’s envelope. This is to ensure that the building as a whole doesn’t have any defects, as this could be a sign that there are damages to the roof.
• Roof Interior Inspection: This is to see if there are any structural issues with the roof and roof deck.
• Rooftop Inspection: This is where we can see if there are any defects to your roof. An infrared roof leak inspection is one of the many techniques we use during an inspection.
• Roof Exterior Inspection: We will inspect areas like your roof flashing and joints to determine if they are in good shape.

If commercial roof inspections in Pittsburgh, PA are something that you need! Call Great Lakes Commercial Roofing at 412-256-8050! We can also provide roof repair and roof installation using Conklin roofing products.

In many cases, people believe that when something pretty serious is going on with their roof, that they should just replace the entire thing and deal with the cost. The idea that repairs will keep needing to be done if anything else is done like a restoration is actually a myth or just a fear. When you choose a company that does a restoration right the first time, a roof restoration is a much better option than having a roof replacement. Companies may try to convince you that you need a replacement, to take your money, but you should always ask around and make sure a roofing company has your best interest at heart. A restoration is not only cheaper for you, but it also will be quicker to finish and take less material. A replacement can be very expensive because in many cases the old roof has to be taken off and then a new one will need to be put on after.

Is Roof Restoration Worth It?

A roof restoration is absolutely worth it. With good workmanship from a solid company, a restored roof can last you around 15 years. If you need a roof to last longer than that and you can spend the money to get a new one, we urge you to take that into consideration, but if you don’t 15 years is a long time. This will also buy you many years to save for a brand new roof when that time comes down the road.

A Green, Energy Efficient Solution

A great way to save money and the environment is to get a roof restoration done. This will use less material and create less waste that ends up in landfills. Overall the material you use for the restoration may or may not be energy efficient depending on what you choose, but the lower usage of material is definitely better for the environment than a replacement.

Call Us Today

Overall the choice is up to you when you need a roof restoration or replacement, but if you have the option, a restoration is a great choice that will keep your roof looking and working great for potentially up to 15 years longer and for much less of the price tag.
