The Different Building Materials To Consider When Constructing A Flat Roof
October 29th, 2008 by The HandymanFlat roofs are a type of building covering that are practically horizontal and give sufficient inclination to permit water to flow. Commonly, flat roofs will be seen more in dry, arid environments where pooling of rainwater on roofs is not much of a problem, but present-day architecture has begun to feature this type of roofing in various homes. Just like traditional roofing, flat roofs are made from various materials, a few being more durable and long-lasting than others therefore making it essential for one to pick wisely amongst the variety of materials flat roofs are built from. As explained at the flat roofing site, flat roofs were traditionally made of a tar and gravel based face, but now, a range of materials have been applied in the manufacture of this form of roofing and flat roofs are now more reliable than they once were.
BUR: A Common Choice
Among the various forms of flat roofs, the most popular is the asphalt built up roof or BUR. These forms of roofs are composed of several layers of plies and asphalt and gravel is popularly used as an exterior material for this form of roofing. A chief concern for the asphalt built up roof is that the material degrades and becomes weak, causing it to be prone to cracks and leaks. It also demands a very energy-intensive installation procedure that also contributes some atmospheric pollution.
Additional Options
Aside from the BUR, there are a lot of other forms of roofing materials for flat roofs. One of them is the Turbo Seal, a self-healing, gel-like membrane made up of about 45% recycled tire rubber. This is lain out upon existing tar roofs and afterwards blanketed with a sheet membrane. Another roofing material that is increasingly achieving popularity is the cold applied liquid membranes. This kind of roofing utilizes glass fiber and offers seamless waterproofing around rough protrusions and details. It doesn’t utilize open flames or heat sources. There is also the CSPE or chlorosulfonated polyethylene more commonly recognized as Hypalon, PVC or polyvinyl chloride, TPO or thermoplastic polyolefin, and Curon or cold-curing glass-reinforced polymer composite. And of course there’s always the EPDM material described at the epdm roofing site.
Making a Selection
Given the wide variety of materials to select from, one can really pick the form of flat roof that is best suited to his needs. There are already a number of manufacturers involved in the business of producing this type of roofing. Flat roofs have certainly developed and advanced in terms of quality and durability and there will surely be one out there that is the solution to any persons building plans.
