Modified Bitumen Roofing Modified Bitumen Roofing stays strong despite heavy traffic and can be walked on. It’s also the cheapest to install. However, it has a much shorter life expectancy. On the average, the lifespan of a bitumen roof is 10-15 years. Old school contractors install modified bitumen to your building using a blow torch, so installation could be a fire hazard. Good news AKA(Mod Bit) comes in a peel and stick variety which makes for easier installation on residential flat roofs. This installation requires base and cap sheets. The cap is what provides the color for the roof. It has now become the preferred method of installation.
