Bitumen Flat Roof Lifespan

Moreover these membranes have excellent insulating properties resulting in long term energy savings.

Bitumen flat roof lifespan.

This article describes common defects found on modified bitumen roofs such as buckling cracking granule loss improper installation details leaks. Color of roof a dark roof absorbs more heat which shortens the lifespan. Since the roof is commonly flat the leaf debris accumulation might not be washed away perfectly. Asphalt coverings use layers of felt combined with molten asphalt and topped with a coating of gravel.

Typically a built up roofing system or a single layer torch on system may be applied on to a built up felt or mastic asphalt roof. Asphalt shingles last 15 to 30 years. Bitumen roofs are one of the longer lasting types of flat roofing materials easily lasting 20 years or more.

Consider over roofing as an option provided the roof structure can tolerate the increased load and good practice details can be maintained at upstands for example. Orientation of roof surface a roof slope facing south will get more sunlight and have a shorter life.
