Standard Bitumen is a black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation. It is used for road surfacing and roofing.

Modified Bitumen

A bitumen, consisting of various flammable mixtures of hydrocarbons and other substances, that are a component of asphalt and tar and are used for surfacing roads, modified by one or more polymers such as Atactic Polypropylene or styrene-butadiene. This type of bitumen (asphalt or tar) is usually modified with plastic and layered with reinforcing materials then topped with a surfacing material. Like BUR’s, the radiative properties of modified bitumen (mod bit for short) are determined by the surfacing material.

Bitumen Roof – Advantages and Disadvantages

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 many different ways to the roof in both hot and cold temperatures. Modified bitumen roofs have a lot of advantages over acrylic roofing, and are often seen as the modern alternative to the built-up roof.

Bitumen Roof- Advantages

There are some advantages to using a bitumen roof on your building or home. Unlike some newer types of roofing, it has a long, predictable track record and can be easily coated with silicone when it starts to leak. Bitumen roofs are one of the longer-lasting types of flat roofing materials, easily lasting 15 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 is supposed to 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 relatively seamless is an advantage.

Bitumen roofing can be very durable if installed correctly. They have a high-tensile strength so are unlikely to develop the kinds of cracks that other flat and acrylic 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.

Bitumen Roof- Disadvantages

Like all roof types, a bitumen roof does have some drawbacks. The first is their black color, which can absorb rather than reflect heat. So imagine that black surface cooking in the Texas heat. Your building becomes an oven. The material itself may not be damaged by UV rays, but if proper insulation (which can add to your cost) is not used with it, this absorption of heat can lead to superheating of the building below.

Bitumen roofing is also available in 1, 2, or 3-ply. The 1-ply material is not durable, and if used can pose problems such as breaking down prematurely, while the 2 and 3-ply material roofs cost significantly more to install, which can make this one of the most costly types of flat roofing products.

Granules need to be included as part of the installation process to help protect the roof from the sun. If they are not included, this can further raise the temperature of the building or damage the roof. Unfortunately, not all types of bitumen roofs include granules as part of the installation process.

Finally, if your roof is likely to hold a lot of water or to gather puddles of standing water after rainstorms, this can prematurely age and damage the bitumen roof.

If you are considering re-roofing your commercial building, it would be advisable to speak to a Silicone Roofing Expert like the folks at Silicone Roofing Houston.
