What You Need To Know About Re-Roofing
By simple definition, re-roofing is restoring your roof by layering a new roof on top of the existing one. If you have metal roofing, you would need to have a new layer of metal roofing placed on top of the existing one. The only provision is that the original roof should not be overly damaged. You can also restore your roof by placing a new layer of shingles on top of the existing ones.
