You should always vet your roofing contractor before hiring them. That way, you can be sure they’re qualified for the job. Checking a contractor’s qualifications should be relatively straightforward. Evaluating their reputation, on the other hand, is trickier. That’s because you’ll need to skim through dozens of online reviews and ask previous customers about their experience.
Fortunately, there’s an easier way of evaluating a contractor’s reputation: check if they have a rating with the Better Business Bureau® (BBB). An A-plus rating is the highest rating a company can earn from the independent nonprofit.
How are BBB ratings calculated?

The Basis for BBB Ratings
Ratings with the BBB are based on 13 factors. In particular, the level of customer service a contractor provides is given significant weighting. Other factors include:
- The number of complaints received by the BBB about the contractor – The volume of complaints, as well as the number of complaints that were resolved or remain unresolved, indicates the level of service a customer can expect from a company.
- Experience in the industry – The previous metric gives an unfair advantage to newer, less experienced contractors, who tend to have fewer customers and, by extension, fewer complaints. That’s why the number of years a company has been in the industry is heavily weighted as well.
The A-Plus Rating: The Gold Standard
To receive an A-plus rating, a contractor has to receive a score of 97 out of 100, which requires a near-perfect score in all 13 categories. As such, you can always expect a high level of service from a residential roofing contractor with an A-plus rating with the BBB.
