Types of Flat Roofs: Pros and Cons

Flat roofs are an excellent way to protect your house. But there are many different types of flat roofs, typically by material. So how do you pick the best one?

EPDM Membrane Roofing

EPDM membrane or ethylene propylene diene terpolymer is a synthetic rubber material that is mostly used for commercial and medical facilities. It’s best for a flat roof right over a garage or some other kind of space that won’t be lived in. That’s because EPDM can absorb lots of heat due to its black color. It’s not the thickest material, either, but the material is so durable some might even call it literally bulletproof. EPDM roofs can last for 25 to 30 years. It is unfortunately weak to punctures, not great for all climates, especially those with lots of sun exposure, and susceptible to punctures from debris.

Standing Seam Metal Roof

Standing seam metal roofs are made up of a series of panels that either lock together at their seams or are seamed mechanically. Standing seam metal roofs can last for around 30 to 50 years with proper maintenance and in the right environments. Metal roofs like these are extremely durable and energy-efficient by nature. They will often bounce off harsh sun rays and to make them more environmentally friendly, they are even recyclable. While the maintenance on these roofs is inexpensive, they are on the higher end of the price scale initially. They’re also pretty complex to install and can be noisy during rain or hail. But for some, that noise may be exactly why they want one.

PVC Membrane

PVC can also be used in commercial and residential roofing. It works pretty well over a living space or bedroom area. PVCs flexibility is one of its greatest benefits, along with its durability and energy efficiency. Proper PVC roofs can last for around 25 years. The membrane itself is durable, though, and it’s often expected to last up to 30 years. It’s resistant against fire, chemicals, punctures, and UV radiation makes it great for extreme climates. PVC is also super easy to install and very low maintenance. Among its other resistances, PVC is also resistant to staining, mold, and algae, which means minimal maintenance. Keep in mind however, PVC is sensitive to rapid changes in temperature.
