Return to Installation

We just went through Hurricane Micheal. While we dod not sustain significant damage, we need a nee roof. Can a metal roof be installed over our existing roof?
Oftentimes metal roofs are installed over existing shingles. The low weight and rigidity of metal is very beneficial. Products that are more heavily textured such as metal shingles and corrugated products lend themselves the best to this practice. However, I am not sure that Florida building code will allow you to go over old shingles. I believe that in your area, removal of the old shingles is required.
Todd answered your question spot on.
Just make that a careful inspection is completed for the roof deck so that you are not just covering up some sort of older defect.
