Modified Bitumen Installation

Modified bitumen (mod-bit) is the proven standard for flat and low-slope roofing across Ontario — used extensively on home additions, garages, commercial buildings, and multi-residential properties. Cobalt Roofing & Sheet Metal installs SBS and APP modified bitumen systems using torch-applied, self-adhered, and cold-process application methods depending on the substrate and building use. Every flat roofing project starts with a thorough drainage assessment to ensure water exits the roof plane as designed.

The most common failure point on any flat roof is the detail work — drains, parapets, penetrations, and transitions to vertical surfaces. Our crews are trained in proper membrane termination and flashing techniques that prevent the premature failures that plague poorly installed flat roofing systems. We also carry out flat roof condition assessments for buyers, sellers, and property managers who need an independent professional opinion.

Cobalt Roofing's modified bitumen installations are supported by our workmanship guarantee and manufacturer product warranties. For commercial clients, we offer multi-year preventive maintenance programs to keep your roof asset performing and your warranty intact. Reach out for a free flat roofing evaluation.
