It’s important to choose a flat roofing material that can handle your area’s climate. Built-up roofing (BUR) and single-ply roofing membrane are two of the most popular flat roofing options on the market. Which is better for your needs?
Genesis Roofing, your trusted roofing company, explains the advantages of each option in this post.
BUR, or tar-and-gravel roofing, is made of alternating layers of bitumen and reinforced fabric and comes in three-, four-, or five-ply varieties. The final roofing layer is made from rock and stone and shields the underlayers from UV rays, extreme temperatures and wind damage. BUR roofing membranes are also less vulnerable to leaks because they lack seams, which are the weak points of a conventional roofing system.
Whichever option you choose, you need to make sure only a licensed roofing contractor handles the installation. To learn more about your other flat roofing options, consult a professional contractor.
There are two types of single-ply roofing: Ethylene Propylene Diene Terpolymer (EPDM) and Thermoplastic Polyolefin (TPO). EPDM is suited to homes in areas that frequently experience hailstorms—hailstones usually bounce off EPDM’s synthetic rubber surface instead of denting it—while TPO is better suited to sunny climates thanks to its reflective surface. (Instead of absorbing heat, TPO membranes reflect heat and ultraviolet rays, lowering cooling costs.
TPO roofing is a relatively new option on the market. EPDM roofing has been used in the commercial roofing industry for more than six decades and has a proven track record. However, thanks to TPO roofing’s resistance against UV damage, it has been gaining traction in the market.
Here’s a buying tip: For added protection against fire damage, you should choose single-ply roofing with a Class A fire rating. EPDM and TPO roofing with an A rating contain fire retardant chemicals that can delay the spread of fire.
