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 […]

How Easily Do EPDM Roofs Puncture?

Chaffee Roofing clients know all about the durability of EPDM, the cost of the product, and how easy is it to install. A common query from our clients is how easily do EPDM roofs puncture? It must be in the top 5 questions customers ask us about EPDM roofs. Our answer is a simple one EPDM, like any single-ply product, is prone to punctures from direct impact. Stabs from a screwdriver or sharp object will make a hole in the membrane. However, EPDM is very durable for regular foot traffic, roof maintenance, rooftop unit maintenance, etc. In fact, some manufacturers are starting to offer puncture resistant warranties on some EPDM roof systems!  As the question comes up a lot, we have compiled our thoughts on EPDM and punctures into a blog post. Let’s take a closer look at EPDM and how to solve the problem of punctures. How can you puncture EPDM? EPDM roofs are also known as rubber roofs. Rubber can puncture, as anyone who rides a bike or drives an automobile will know. Once you know the dangers, then you can avoid them. Falling branches during a storm can spear the EPDM causing a lot of damage. Workers on the roof can drop a sharp tool, such as a screwdriver, through the EPDM roof or even puncture it by wearing the wrong footwear. […]

The Fault With EPDM Roofing Seams

The Fault With EPDM Roofing Seams EPDM is a fine roofing material and one which many Chaffee Roofing clients use. A significant advantage of EPDM roofing is its durability and high UV resistance. However, many flat roof owners find fault with their EPDM roofing seams, particularly on older EPDM roof systems with glued seams once they begin to wear down. Extensive patching to EPDM roof systems can be expensive because the accessories are almost as expensive as the EPDM field membrane itself. The cause of most replacement EPDM projects? The seams and flashing details. The EPDM membrane itself may be fine but when the seams and flashings begin to go, customers are left with two options: extensive patchwork or total replacement. Why faulty seams? A professional roofer will install your EPDM roof to the highest standards. At Chaffee Roofing, we only use highly qualified roofing professionals, who are guaranteed to always do a quality installation using premium materials.The problem is that EPDM relies on adhesives to hold the seams and flashing details together. With TPO and PVC roof systems, the seams and flashings are heat welded, which means that the product becomes one sheet. With EPDM, heat welding is not possible, so primers and adhesives are used. So what is the downside? The adhesives break down and dry out over time. It is inevitable, and […]
