Roofing Materials Compared For Lifespan And Durability

Lifespan and durability are not the same for all roofing materials.  Without getting service from a roofing material, what is the point of your investment? When looking for a replacement roof, or choosing a new one, take time to investigate these two qualities. The short time spent looking at your alternatives may save you a lot of money in the future. There are many roofing materials available, so making the right choice may not be easy. When you know what you are looking for, then the decision becomes a simple one. To help make that decision take a look at your alternatives. TPO is one choice TPO has proven to be good on flat roofs. It is easy to apply and a cheaper alternative to other roofing materials. The lifespan of TPO is around 20 to 30 years, depending on the thickness of the membrane and how it is installed. A significant factor in the life of TPO is the quality of the material, which can vary from manufacturer to manufacturer. Always insist on top-quality TPO from a reputable manufacturer like Carlisle, Firestone, or GAF. Additionally, spend the extra money on the thicker 60 mil or even 80 mil TPO. The extra thickness will add years to the lifespan of the roof. TPO is durable and does not corrode. TPO is typically heat welded where […]

TPO versus EPDM: which system is better?

One of the most common questions we get is: Which roof system is better, black “Rubber” EPDM or white “Thermoplastic” TPO? Both are similar in price, both come with 15-30 year warranties, both are made by reputable manufacturers, and both are widely installed throughout New England.  So that begs the question, is one roofing material actually better than the other? Key Differences In my view, neither roof system is definitively better than the other. However, they do have key differences that may have an impact depending on your building. These differences include: Heat and UV Resistance: When it comes to heat and UV resistance, EPDM is the superior product. As a general rule, EPDM can reach temperatures of around 180 to 200 degrees, whereas TPO can only reach temperatures of around 140 degrees. This can make a difference in buildings that have a high heat output or a lot of dark, high heat surfaces surrounding the building. Grease and Oil Resistance: TPO is far better with food byproducts, such as grease and oil. Grease guards should always be used, and neither system is warranted against grease, but TPO will hold up much better than EPDM in the event of a leakage or fluid backup.  Puncture Resistance: In my view, both products have similar puncture resistance. However, many of the manufacturers are starting to provide puncture […]

Heating versus Cooling Your Roof: Which is Better in New England?

Heating versus cooling a flat roof in New England has always been a hotly contested debate. I have been to countless seminars on this subject, and have heard the following arguments: In New England, we are heating our buildings more often than cooling them. On the average building in New England, it’s undeniable that we are heating our buildings more often than cooling them. Air conditioning typically runs consistently from June to August (3 months). On the other hand, heating typically runs consistently from October to April (7 months). As a result, the argument is that we are better off installing a black roof system that heats the roof than a white roof system that cools the roof. The heating benefit lasts for 7 months compared to the cooling benefit, which lasts for only 3 months. The strongest argument that I have heard against this theory is that during the winter, once the snow falls, the roof is white regardless. The black membrane may help melt a small amount of snow, but much like your driveway, once snow builds up, you have a snowy white surface instead of a black surface. This doesn’t happen during the summer, so the cooling benefit is there during the entire season. Rooftop equipment benefits from a cooler surface. During the hottest points of the summer, a black roof system […]
