Methods Of Flat Roofing

Roofing Built-Up

Built-up roofing is one of the oldest methods of construction for flat roofing, and it is still among the most common roofing methods. Installing BUR begins with the installation of moisture and vapor barriers over the simple roofing frame. Installing layers of bitumen that alternate with waterproof elements would be the next step. Fiberglass sheets, roofing fabrics or tar paper may consist of these waterproof elements. Hot gravel and tar are part of the bitumen mixture, but can contain other cumulative materials as well. BUR roofing is measured in terms of the number of layers or layers it comprises, with higher numbers suggesting installations of higher quality.You may want to check out Puyallup Contractor for more.

Roofing Membrane

Membrane roofs are among the most robust and most water-resistant roof styles available on the market. They are made of sheets of PVC, rubber and/or thermoplastics, each with a thickness varying from 30 to 60 mm. Membrane roofing sheets are directly assembled without the need to install a separate vapor or moisture barrier over the roofing structure. In order to provide some form of thermal resistance, insulation can also be put under the membrane. In either of the two cases, the membranes can then be connected. They can be handled with a special sealer that helps the sheets to bind chemically or can be heated in order to melt the seams together. When used, both of these strategies can help create a neat and seamless installation that is very necessary and helpful in keeping the building water-free.

Foam Roofs Spray

Spray foam roofing is another roofing technique that uses polyurethane foam that binds with the roof and forms a protective layer at the same time. This method of roofing starts with sheets of firm foam insulation that are fastened to the structure of the roof. Using a spray gun, the foam solution is then mixed and added to the roof. In order to permit adequate drainage, the thickness of the foam layer varies across the roof surface. An elastomeric coating is applied over the surface to guarantee that the foam roof remains reliable and effective. This coating would also add certain additional properties of water resistance that are also useful in preventing the spread of fires in emergency situations. Sand and other accumulative materials may be combined on the top of the surface layer to increase the final appearance of the roof.
