The Benefits of Hiring a Factory-Certified Roofer

by Javier Martinez, a Diamond Certified Expert Contributor

MORGAN HILL — A new roof is a big investment, so you’ll want to make sure yours is backed by a strong warranty. However, keep in mind that your warranty may only be as good as the contractor you choose.

Most roofing manufacturers offer certification programs, whereby roofing contractors can become certified to install their products and systems. Once certified, these contractors are eligible for extended warranties due to their verified expertise. So, to maximize your roof warranty, your best bet is to hire a factory-certified roofing contractor.

One example of this is GAF Materials Corporation’s Master Elite Contractor program. By hiring a GAF Master Elite Contractor, your roof will be eligible for an exclusive warranty that provides 25-year coverage on workmanship and 50-year coverage on materials. What’s more, GAF will honor its warranty even if the installing contractor goes out of business, giving you even greater confidence in your investment.
