The Benefits And Drawbacks of Including a Layer of Shingles

House owners typically question whether it's economical to include an additional layer of roof shingles instead than tearing off the old ones.

While adding one more layer may appear less expensive upfront, the possible damages and the lowered roof life might make it much less of a bargain than it seems.
