It can be difficult to find a reliable roofing contractor who does high-quality work. One thing to look into is whether the contractor has been certified by a major roofing manufacturer.
Most reputable roofing manufacturers require that the roofing contractor who installs their products be a manufacturer-approved contractor; otherwise, they will not issue a warranty for the work.
Contractors who feel confident in the high quality of their work will often go the extra mile and become manufacturer-certified. The process for becoming certified normally includes applicator training programs run by the manufacturer’s technical department, a required minimum number of years of roofing experience, and inspections of actual roofs installed by the contractor.
You can reason that if the roofing manufacturer trusts these contractors to perform the work to a high standard (so the manufacturer won’t end up losing money on warranty issues), then you can trust them, too.
(This, of course, is not always the case, and we are not endorsing any of the contractors you find through these links.)
The following list provides links to the databases of approved contractors of the major roofing manufacturers. These databases are generally searchable by zip code, so you can find a contractor near you.
