Another important and critical importance of choosing the right roofing material is ventilation and insulation. The chosen materials should provide good ventilation to prevent the buildup of heat and moisture in the attic area. In addition, proper ventilation ensures that structural damages are prevented thus increasing the durability of the roofing material.
Here is a list of 9 different types of roofing to consider for your next re-roofing job:
Roofing material is the outermost layer on the roof of a building, sometimes self-supporting, but generally supported by an underlying structure. A building's roofing material provides shelter from the natural elements. The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting structure. Those types of roofing material which are commercially available range from natural products such as thatch and slate to commercially produced products such as tiles and polycarbonate sheeting. Roofing materials may be placed on top of a secondary water-resistant material called underlayment.
Asphalt shingles are the most common roofing materials in America because they're effective in all environmental conditions. Quality varies widely, so ask whether they pass the ASTM D3161, Class F (110 mph) or ASTM D7158, Class H (150 mph) wind tests and the AC438 durability test. Upfront costs are low, but you should expect to replace the shingles after about 20 years. If you live in a hail prone area, consider impact resistant shingles which have a UL 2218 Class 4 rating. Impact resistant shingles may qualify for a discount on your homeowner's premium.
