Roof Inspection Case Studies: Additional Layers of Shingles Leads to Disaster on Ranch Home
While inspecting a home in New London with two layers of asphalt shingles we found a number of issues, the most notable however is the added heat stress from adding another layer of shingles causing premature shingle failure and “peaking” of the shingles allowing debris to get under them and lead to leaks.
We always recommend avoiding a layover due to the added complications and potential for premature failure. If you happen to buy a home with two or more layers however, your best bet is to have one of our certified roof inspectors examine your roof and tell you what’s going on.
