Modified Bitumen, also known simply as ‘Mod Bit’, is a popular roofing system for flat and low-sloped roofs. Originating in Europe, mod bit roofing systems were developed as an alternative to traditional built-up roofing (BUR) systems. Over the years, they have grown in popularity throughout Ontario because of their fireproof qualities and ability to withstand extreme temperatures.
The primary waterproofing component of this roofing system is asphalt, which has been reinforced with synthetic rubbers or plastics to improve flexibility, elasticity, and UV resistance. There are 2 main types of mod bit roofing membranes, SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene), both provide excellent protection for your commercial roofs.

Modified bitumen suits roofs that see foot traffic or need multi-ply redundancy. Its layered, asphalt-based construction is tough and puncture-resistant, making it dependable for many commercial and industrial buildings.
A well-installed and maintained modified bitumen roof typically lasts 20 to 30 years. The multi-ply build gives it durability, and regular maintenance protects the seams and cap sheet.
It depends on the building. Modified bitumen offers multi-ply redundancy and toughness underfoot, while single-plies like TPO, EPDM and PVC are lighter with welded or taped seams.
It is applied in multiple plies bonded to the roof using torch, hot-asphalt or self-adhered methods depending on the roof. We select the safest, most suitable method and always follow strict fire-safety practices.
