There are several options for flat roofing, but it depends on what you want. Choosing the system best suited to your needs, budget, and building should be straightforward. While talking to a roofing specialist is recommended, we will share the pros and cons of the roofing options in the next few blogs.
As budgets become tighter, both personal and commercial, the decision for your flat roofing is important. So, it is essential you weigh the pros and cons of a system to see what will work best for you.
This type of roofing is the installation of a flat membrane of rubber or other synthetics. There are two main types of simple ply roofing.
A proven track record. This is especially true of EPDM. EPDM has been in use for over 60 years and has allowed for objective testing. Testing places this choice in the high-performance bracket. Unfortunately, TPO has not been around as long and has not been sufficiently tested, although its use is growing in popularity.
Reflective and Retentative Properties. This is the area where TPO is growing in popularity. Although known as ‘white roofs, ’ TPO is available in shades of green, blue, tan, grey and red. This is a highly effective reflective roofing material. EPDM is known as ‘black roofs’ because of its dark shade. In addition, EPDM is known for its wearability and heat retention, making it a cost-effective choice in cooler climes.
Ease Of Installation. Both types of single-ply roofing are relatively quick and easy to install. To fuse the seams, TPO uses a hot-air gun to fuse the seams. EPDM uses seam tape.
Lightweight & Flexible. While you can select to have several layers of single-ply roofing, it remains lighter than most other types of flat roofing options, which helps reduce the stress on the building.
Can Be Easily Pierced. The other side of the coin to being lightweight is that this type of roofing can be easily punctured by loose tools, gravel or screws & nails. In addition, this roofing does not have a hard-top cover, making it vulnerable to leaks.
Difficulties With Roofing Protrusions. Here we are talking about A/C units, air vents, skylights, plumbing vents, and others on the roof. Applying either of the single-ply options can be difficult because you must cut our smaller pieces to place around the protrusions. Essentially building up the roof around them. This is time-consuming, therefore, costly, and they are a particularly vulnerable area for leaks.
Problems With The Seams. However, single-ply roofing is sealed, either heat, mechanical fasteners, adhesives, or tapes. Therefore, they are more vulnerable to leaks than other roofing systems.
Degradation Due To UV Rays. Intense sunlight and UV rays can degrade the adhesives used in rubber membrane systems. As a result, they make the seams vulnerable to leaks. Plus, if there are any punctures to the roof and the UV has access to the adhesive layer, this can cause more damage with the adhesive deteriorating.
