Bitumen Asphalt Flat Roof

Firestone building products manufactures traditional built up systems modified bitumen membrane systems hybrid built up and modified bitumen systems.

Bitumen asphalt flat roof.

An epdm rubber roof can be bonded to asphalt but this depends on the rubber membrane system you are using. Materials such as layers of fiberglass or polyester are added to the asphalt to add strength to a flat roof. The resulting asphalt by product was of lower quality. It cannot be bonded to uneven surfaces such as shingles as this hinders the membrane from successfully bonding onto the surface.

Some observers suggest it s harder to replace a flat roof than a traditional pitched shingle roof because of the labor required to remove its layers especially on older flat roofs. Firestone asphalt roofing delivers exceptional performance on flat and low slope commercial roofs in even the most extreme climates and applications. Development modified bitumen was developed because oil refineries had figured out ways to use more products from crude oil. The good news is a longer lasting roofing material has a lower environmental impact.

Bitumen roofs have been around for a long time. Modified bitumen roofing is a roofing asphalt. But now flat roofs often are constructed with fewer layers because of improved waterproofing technology. This could mean flat roofs may not raise the same red flags they used to.

Asphalt flat roof construction repair and replacement with an epdm rubber roofing membrane. One of the longer lasting roofing options for flat roofs is bitumen roofing or a modified bitumen roof. Built up roofs are installed using several layers of a special type of roofing felt that has been asphalt impregnated and embedded in bitumen applied with a hot mop. This surface is susceptible to cracking and blistering which reduces the typical lifespan to just 10 to 15 years.

The hot applied asphalt or coal tar pitch blends with the bitumen soaked roof felt and creates a monolithic roof membrane. 5 tell tale signs it s time to repair or replace your asphalt or felt flat roof. Modified bitumen roofs use an asphalt membrane as the base of the roof itself. Modified bitumen is a type of asphalt product that can be applied in a number of ways to the roof in both hot and cold temperatures.

Flat roofs are hard to replace. Bitumen roof advantages and disadvantages. Modified bitumen is installed in multiple layers multi ply roof each of which is torched to the surface below at every turn of the roll. Modified bitumen an asphalt based multi ply flat roofing system is considered a modern take on its close cousin bur or built up roof.
