The install of 3tab shingles usually comes with a pro-rated 25 year manufacture limited warranty. This normally only covers a manufactures defect for the time frame. The estimated life of a 3tab shingle roof is approx. 8-10 years based on normal weather conditions. Mind you this is always dependent on what kind of weather is has to endure. Expect to show minor wind damage in moderate storms. In no way does Fair Trade Roofing guarantee these estimates.
