Fort Worth Roofing: Article About Built Up Roofing Systems
When constructing a commercial building, a business owner must consider roofing options. If a low pitch roof needs to be installed, built up roofing may be the best choice. A Fort Worth roofing expert can help in the decision making process.
Built up roofing is the most popular low pitch roof. Used in the country for over 120 years, it is often seen on commercial and industrial buildings. With a lifespan of 15 to 40 years, its popularity is due to its longevity and durability.
Hot asphalt built up roofing is made with several layers of roofing felts, also called ply sheets, and bitumen. Bitumen is composed of asphalt or tar. These layers of roofing felts are saturated with bitumen for reinforcement. Fiberglass or organic mats are placed in between the fabric layers, and an insulation layer is added. An aggregate coating, the flood coat, covers all the layers.
Cold built up roofing is another type of built up roofing. It is made using cold bitumen, which is an asphalt that needs no heat for application. It is applied as a spray or with a squeegee. In comparison to hot asphalt, it doesn't have toxic fumes, it isn't as environmentally damaging and it performs better.
The surface of a hot asphalt or cold built up roof membrane may be a flood coat, which contains an aggregate of gravel or rock slag.

One benefit of built up roofing is that it provides protection against water. The layers of bitumen and plies make a barrier against rain, snow or ice. When properly installed, these layers are resistant to snow, hail and wind.
Another benefit is that a built up roof provides protection against the sun. The bitumen saturated layers minimize the conduction of heat between the inside and outside of a building. This reduces cooling and heating costs. These layers also protect against ultraviolet rays. A reflective material or paint may be applied to the surface in order to further minimize the effects of ultraviolet rays and conduction.
The biggest negative is that built up roofing is costly and takes longer to install. The installation of hot asphalt built up roofing creates hazardous fumes. The finished roof can be damaged by wind and water.
When deciding whether to install a built up roof, the pros and cons must be considered. To have a full understanding of built up roofing systems and whether to install one, a business owner may wish to consult a commercial roofing expert.
