A low-slope roof on your screened-in porch or any flat roof facet will require a different roofing material than asphalt shingles. Even if you replace your entire asphalt roof, the low-slope area must be covered with a membrane or metal roof.
A membrane roof is the most common and cheapest option, but both are excellent choices. The good news is that you’ll have a lot of options of roofing membrane choose from!
Our goal at Tier 1 Roofing located in OKC and Fort Smith AR is for you to have all of the details you need prior to choosing your residential roofing style. Determining the type of roof membrane for your low slope or flat roof is important because of this.
A low slope roof must have a roof membrane. You’ll learn the differences between the three types of roof membranes as described by roofing companies.
Membranes for roofs come in three varieties: EPDM, TPO, and PVC It depends on the look you’re going for and what rooms are directly below your roof if you choose to use any of these.
In the commercial and medical sectors, EPDM is made up of a synthetic rubber black membrane that is widely used. Despite its popularity in commercial roofing, EPDM has a place on residential roofing as well!
If you plan to use it over a bedroom or living area, we wouldn’t recommend it because of the heat it will absorb. For a garage or other non-living space that can be viewed from a window, we recommend EPDM due to its black membrane that won’t get visibly dirty. As a result, EPDM roofs are bulletproof. EPDM roofs with a 0.060-thickness fully adhered can last 25-30 years.
In commercial and residential roofing, TPO is a single-ply white membrane. Instead of absorbing heat like EPDM, TPO’s white membrane reflects it.
This is a great option for flat roofs or dormers with a low slope over a bedroom because it keeps the room cooler. You can still opt for EPDM if you prefer it.
Just remember that if you have windows looking over the membrane, white will get dirtier much faster than black. If you care about what you’ll see when you look out the window, either one will perform the work of keeping the flat roof free from leaks.
As long as it’s installed properly, TPO membrane is as durable as EPDM.
Commercial and residential roofs use PVC (polyvinyl chloride). When it comes to flat or low slope roofs, PVC is an excellent option.
Besides being white membranes, PVC and TPO share a lot of similarities in terms of their physical and chemical composition. Installation is virtually identical. As a result of its flexibility, PVC has been around for a longer period of time than TPO. As with TPO, a properly installed PVC roof should last for 25 years.
