Types of Built-Up Roofing and Their Benefits.

Built-up Roofing

Built-up roofing is the most popular material used on low-slope roofs. A built-up roofing, is composed of several layers of bitumen surfaces, and finished up with an aggregate layer or coating. Recent built-up products incorporate a rigid insulation layer as part of the built-up roofing. The fabrics or layers used on built-up roofing are called ply sheets. These sheets are commonly reinforced with fiberglass mats or organic mats, depending on their application. Ply sheets are commonly produced in a standard size about 36 inches width.

Types of Built-Up Roofing

There are several types of built-up roofing alternatives for you to use. Other kinds of built-up roofs are smooth Asphalt built up (Hot or Cold), and Ballasted Asphalt built up. The bitumen material commonly used in built-up roofing systems is asphalt, coal tar or cold-applied adhesive. The surfacing and materials used on built up roofing are so wide that it all depends on the project and costs of your project. Ballasted asphalt is being used more regularly than before, because it can provide an excellent finish surface and its material is a better fire retardant agent.

There is also Cold Built-Up roofing that instead of using hot and asphalt for its application, it can be spray applied or applied with a squeegee. It doesn’t have toxic fumes when applied and it is better for environmental sensitive projects. Cold Built up is not dependent to weather and it has a better performance when compared to hot built-up roofing.
