It is sometimes recommended that you could have up to (2) layers of asphalt shingles on your roof without tearing everything off back down to the decking. That doesn’t mean that we haven’t seen roofs with 3, 4 or even 5 layers. By the time you start tearing off that 2nd layer, you’re usually sweeping or shoveling the shingles off.
Blistering, Molding and Deteriorating Shingles
Your old shingles have been blistering, molding and deteriorating in the Texas heat for years. Even 1 layer roofs with old hail damage often have to be scraped off with a rake and a powerful leaf blower. Sometimes, you’ll find an old layer of wood shingles under there. When that happens, you’ll need to tear everything off and put solid decking down (called a “redeck”).
Once the granules start falling off, whether by a hail storm or just age, there’s nothing to protect the fiberglass or asphalt mat from curling up and letting water in your home.
