Can a Metal Roof Be Installed Over Shingles?

In many cases, a metal roof can be installed over shingles, but it depends on local code, the condition of the existing roof, and the structure underneath. The old shingles must be in decent shape, and the roof has to be able to support the new system properly. Some areas limit how many layers of roofing are allowed, so a contractor should always check the rules before starting. While a roof-over can save time and reduce tear-off costs, it is not the best solution for every home. If the old roof has major damage, moisture problems, or too many layers already, a full tear-off may be the better choice. A proper inspection will show which option makes sense.
