Tips In Choosing The Right Roofing Contractor
A roof is very essential in every house. They offer protection of the occupants from the weather outside. But the life span of one's roof relies on several factors; kind of roofing, quality of material, and exposure to harsh weather elements among the top. With regular maintenance and usual weathering factors, a roof can last anywhere from 10– 100 years.
Typical roofing material like built up roofing usually lasts 12– 20 years, metal roofing 15– 40 years, wood shake or shingles 10– 40 years, asphalt shingles 15– 20 years, and specialty material like around 100 years under good conditions. Leakages start as small cracks in roofing material which could not show up; water may collect in an adjacent area. To identify such damage, a close inspection of the roof might be necessary.
That is so cool that metal roofs can last upwards of 40 years. I might have to look into getting a metal roof on my house. That why I'll never have to worry about it for a very long time. http://www.independentroof.com
