In some cases, it is possible to reroof over existing shingles, but it’s important to evaluate the condition of the current roof before proceeding. Reroofing can be a cost-effective option if the existing shingles are in good condition, there’s only one layer of shingles, and there are no underlying structural issues. However, if the existing shingles are severely damaged, there are multiple layers of shingles, or there are signs of structural problems, a complete tear-off and replacement may be necessary.
