Seeking Different Types Of House Roofing

Roof Tiles Materials Options

Every building from a doghouse to a skyscraper has a roof. The climate of an area usually determines the type of roof tiles materials. Most home roofs are sloped to facilitate the run off of rain; however, flat roofs are common in commercial buildings. If needed, a quick flat roof repair involves spreading a sodium bentonite sealer over the area of the leak. The bentonite expands to plug the leak until a roof replacement estimate can be obtained. Flat roofs generally have a tar and gravel surface, or they are a sealed metal roof made of copper, tin, aluminum or other metal.

Homeowners have many options when choosing roof tiles materials. Asphalt roofing shingles are made of bitumen embedded in either a fiberglass reinforcing mat or an organic cellulose fiber mat. The fiberglass variety make up 90 to 95 percent of all asphalt shingles sold. Warranties vary from 20 to 50 years, but it is also a good idea to ensure that the shingles meet certain manufacturing standards. ASTM International, formerly known as the American Society for Testing and Materials, will only certify products that meet or exceed their rigorous testing. The standard for fiberglass shingles is called ASTM D-3462, and for organic shingles it is ASTM D-225. The package will be labeled if it complies with the standard.

If an area receives high snowfall, metal can be a good choice of roof tiles materials. Because of the smooth surfaces, the weight of the snow is shed easily. Metal roofing materials are recommended due to their fire resistance properties and overall durability. Several metals can be used for roofing depending on different factors. For example, steel is used on most metal roofs, because it is heavier and sturdier than aluminum. A standing seam metal roof is made from a type of sheet metal that has a self sealing, raised seam. The interlocking panels are typically zinc coated for corrosion protection.

Prices for roof tiles materials vary widely. Slate roofs are considered the best, but they may cost as much as the rest of the house. Vinyl roofing and vinyl siding costs are usually lower than that of other materials. As steel roof trusses and steel framed houses increase in popularity in a particular area, the prices drop proportionately. Concrete roof tiles are another economical and durable option.
