Types of Roofing
Many different materials and tools are used daily to construct many different kinds of roofs for houses which provides necessary protection and security for homeowners.
Metal roofs in the present day are not like they were in the past. “Thinking back to the old barn roofs of years past that used tin, strike that vision because today’s metal roofs are light years ahead of those”. Fully recyclable metal roofing materials come in steel, aluminum copper and alloy strips with steel holding the most popular spot with consumers. Todays metal roofs are fire resistant, maintenance free durable (50-75) years), metal roofing last longer than any other material on market such as shakes, clay tiles, shingles (Scudder Roofing). Standing seam is a type of metal roofing. Which is made up of many vertical interlocking panels. Where the seams join is raised to prevent any water from seeping into or underneath the panels. Metal roofing comes in a few different ways. It comes in ribbed panels which are (about 3 ft. wide and from 10 to 20 ft. long) it has joints that lap on the ends. This type looks good on popular homes or high-end contemporary homes. They use this roof on steep roof and country’s that have a lot of snow. Snow will not stay on this metal easy. This roof comes in varieties of colors (Provey).
Flat roofs are the easiest roofs to identify. This roof is easy to construct, safer because the roofer can stand on it (Kathryn). Water cannot run off of a flat roof like sloped roofs (Ragsdale). This type of roofing requires more maintenance because debris can gather on the roof and it has nowhere to go (Kathryn). One type of flat roof is EPDM (Ethylene Propylene Diene Monomer). “EDPM roofs are single- ply membranes (one ply roofing material, not multiple plies laminated together) “. EPDM is made of ethylene and propylene, which are mine components of rubber. This roof is inexpensive, easy to install, has no odors, fumes, and is clean to work with. Life expectancy on this roof is 15-25 years (depending on environmental conditions). Another type is PVC (Polyvinyl Chloride). PVC is single-ply roofing membrane. PVC membrane as many different manufactures and they have their own slightly different recipe for its PVC product. This type of roof reflects nearly 90% of heat of the sun, which lowers energy costs. Life expectancy on PVC is 30+ years. Then there is TPO (thermoplastic polyolefin) . TPO is made up of a single-ply roof membrane. The top ply contains cool roofs pigments. The bottom ply contains TPO ingredients to help provide consistent weld of top and bottom plies and fillers. The formulation is constantly changing because of all the different manufactures of TPO roofing systems. This type roof is excellent resistance to ozone, it is algae- resistant, environmentally friendly, safe to install, highly resistant to tears, impacts, and punctures, and is also flexible to allow movement of...
