This is a common consideration for homeowners looking to upgrade their roofing without the hassle of tearing off existing shingles.In general, installing a metal roof over shingles is not only acceptable but can also be beneficial. It helps in retaining the insulation properties of the existing shingles, while also offering additional protection against the elements.
