MODIFIED BITUMEN

MODIFIED BITUMEN ROOFING

One of the longer lasting roofing options for flat roofs is bitumen roofing or a modified bitumen roof. 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. Modified bitumen roofs have a lot of advantages over other types of membrane roofing, and are often seen as the modern alternative to the built up roof.

There are several different advantages to using a bitumen roof on your building or home. Unlike some newer types of roofing, it has a long, proven track record that can be counted on. Bitumen roofs are one of the longer lasting types of flat roofing materials, easily lasting 20 years or more.

Regardless of how the material is applied (self-adhesive sheets, hot-mopped asphalt, or cold-applied adhesives) the seams are usually melted together which help stop leaks. Other types of membrane roofing have seams that are left open or covered with another material that can weaken over time, so the fact that a bitumen roof can be seamless is a big advantage.

Bitumen roof is also very durable. They have a high-tensile strength so they are unlikely to develop the kinds of cracks that other flat and membrane roofs are known for. They are also rated against wind, fire, and hail so they are unlikely to be damaged in the event of a storm. Included in this is usually a very long manufacturer’s warranty that can help to guarantee the roof’s longevity.
