What Is Flat Roofing?

What Is Flat Roofing?

Flat roofs are roofs that are almost flat in comparison to pitched roofs. Flat roofs can have a pitch of up to 10 degrees. Flat roofs are often found in commercial buildings around the globe. Flat roofs are standard worldwide, with each region having its traditions and preferred materials.

Flat roofs can be constructed of concrete or masonry in warmer climates where freezing is unlikely. This is because it is more cost-effective and easier to make than timber.

What are the different types of flat roofs?

BUR uses tar but bitumen can be used as a substitute. Tar is messy and smells bad. Bitumen is made up of layers of asphalt coated with a protective sealant or another protective material. Bitumen comes in easy-to-apply pieces that can be slid on and off. Peel-and-stick asphalt is a cheaper option than poured asphalt.

BUR – Built-Up Roof
The most popular flat roof is the Built-Up Roof. It is made up of felt and adhesive layers. The deck board is the first layer, followed by insulation. The layers of felt and asphalt are then changed. Finally, gravel is added to the asphalt. The top layer reflects sunlight and keeps the interior insulated, and it protects the lower layers against weathering. Gravel can easily be replaced so that you can add more when necessary.

GRP – Glass Reinforced Polymer
GRP roofing, also known as fibreglass, is a great choice. Although you may need to complete a training course, GRP roofing is much easier than BUR, which requires a certified team.
