What is the difference if 25, 30 and lifetime shingles?
The difference between 20 year and 30 year is the style and composition of the shingle. A 20 year shingle is a flat, single sheet 36″ wide sheet with three tabs. A 30 year shingle has two layers molded together to provide longer protection and give the roof an architectural look. Lifetime material has the same look as the 30 year but is thicker and stronger. In addition, the fewer replacements are made the less material has to be disposed of.
