Can a metal roof be installed over my existing asphalt shingles?
Absolutely. Very often a metal roof will be installed over an existing asphalt roof. This is a very common and proven installation method. This is possible in part because even though a steel roof is much stronger than an asphalt roof, it weighs significantly less. Installing your metal roof over your existing shingles saves money, eliminates the mess of a shingle tear-off and disposal, and provides extra insulation to your home. However, every job is unique and there are times when it is best to remove the existing roof, such as when there is rotten wood decking. Your Chandler consultant will be able to go over all the options with you after doing a complete evaluation.
