2-Look for manufacturer designations.Manufacturer designations are considered a badge of honor because the contractor must pass certain minimum requirements to be factory-certified (although, some manufacturers have more stringent requirements than others). GAF strictly enforces their top designation by only allowing 2% of roofing contractors per market to be recognized as Master Elite® Contractors. (Unlike other manufacturer designations, Master Elite® Contractors cannot use this top designation in another territory, only in the location of the storm. Find a Master Elite® Contractor near you.
3-Research Better Business Bureau (BBB) ratings. Some contractors blow in (no pun intended) right after a storm looking for work, so it’s important to look them up on the BBB website and make sure they have a good score. Stay away from contractors who do not exist on BBB.org. GAF Master Elite® Contractors are required to maintain satisfactory ratings with the BBB in order to retain their certification.
4-Get an extensive warranty. Not all contractors can offer manufacturer warranties that include coverage of the contractor’s workmanship. If a contractor installs the roof incorrectly, it may take months or years for the damage to show up.
