Professional vs. a DIY roof repair

While homeowners may want to DIY minor shingle or flashing repairs, professionals are better equipped to handle complicated repairs and roof replacements. Contractors certified by GAF1 are insured, licensed in the state where their principal place of business is located (if required) and they can offer GAF enhanced limited warranties2 on qualifying roofing systems.
1Contractors enrolled in GAF certification programs are not employees or agents of GAF, and GAF does not control or otherwise supervise these independent businesses. Contractors may receive benefits, such as loyalty rewards points and discounts on marketing tools from GAF for participating in the program and offering GAF enhanced warranties, which require the use of a minimum amount of GAF products. Your dealings with a Contractor, and any services they provide to your are subject to the Contractor Terms of Use. Visit gaf.com/gaf-contractor-terms-of-use for details.
