Asphalt shingles can last from 12 – 30 years, depending on the conditions around your home. But when only a portion of the shingles have failed prematurely, it suggests that the problem is not with the roofing material but with your attic ventilation.
The roof is actually a system working in tandem. The components are: Shingles Flashing Soffit, Fascia & Gutters Attic Ventilation Air Infiltration Insulation If one of these links in the chain is out of whack, the entire roof system is put in jeopardy.
