FREE Storm-Proof Upgrade with every Full Roof Installation!
If you’re after superior waterproofing protection, high tensile strength, affordability, and a long lifespan for your commercial roofing system, a modified bitumen roof is a great choice! What sets it apart from other commercial roofing systems designed for low-sloped or flat roofs is that it is made from a combination of tar asphalt and rubber polymers or fiberglass reinforcers. Our team of roofing experts can explain the features of each modified bitumen material so you can make the best choice for your property. With us on the job, you can rest easy knowing that you’ll get all the benefits of a durable, leakproof modified bitumen roof.
Self-Adhered Modified Bitumen (SA Mod-Bit) membrane roof system delivers the reliable protection of traditional modified bitumen roofing for low-slope roofs. The advantage for building owners is rolled asphalt is an attractive roof available in multiple colors. Rolled asphalt systems are used in both residential and commercial applications with the advantage of being lower cost than EPDM membrane roofs.
Where Modified Bitumen Works Best
Modified bitumen is a strong choice for flat and low-slope roofs on small commercial buildings, multifamily properties, and residential areas like porches, additions, and garage roofs. It performs well on roofs with lots of penetrations, transitions, and short runs where a multi-layer system can provide extra protection and durability.
Types of Modified Bitumen Systems
There are several ways to install modified bitumen, including self-adhered, cold-applied, and torch-applied systems. For many occupied buildings we prefer self-adhered and low-odor options that reduce disruption while still providing a tough, multi-layer roof. During your inspection, we will recommend the system that best fits your roof, building use, and local conditions.
Modified Bitumen vs Other Low-Slope Options
Modified bitumen combines some of the benefits of traditional built-up roofing and modern single-ply membranes. Compared to single-ply systems like EPDM or TPO, modified bitumen uses multiple layers for added toughness and puncture resistance. It is often a practical, cost-conscious option for smaller flat roofs, roof sections with lots of details, and projects where a granulated, shingle-like surface is preferred.
