Roof overlay is a roofing process where a new layer of shingles is applied on top of your existing layer of shingles. This project is one way to prolong the life of your roof without a complete roof replacement. That said, an overlay only works under certain conditions. Learn more about it in this blog.
Roof Decking Must Be Strong Enough
For an overlay to work, your roof still needs to be in relatively good shape. Specifically, your roof decking has to be strong enough to support the weight of an overlay. If the roof deck is in poor condition, the new roof may fail.
Existing Shingles Need to Be in Good Shape
For an overlay to work, your shingles also need to be in decent shape. If your shingles are cracked, breaking down, and missing, an overlay is not a good idea. Because the shingles with extensive damage are a sign of water damage under the shingles.
Most Roofs Can Only Support Two Layers of Shingles
Shingles are really heavy, and your roof decking is only designed to support so much weight. When your roof starts to get too heavy, the decking and tresses under your roof could become compromised and damaged. If you already have two layers of shingles on your roof, it may be time for a tear-off.
