Arguably the easiest way to evaluate the quality of a roofing contractor's work is to look at his past jobs. When you are choosing a roofing contractor, many will gladly provide you with a list of references if they believe that their work speaks for itself. You should look for references that are a few years old, so that you can assess how durable the construction is. It can also be important to find a contractor that is the right fit for you. Choosing someone that you aren't comfortable with can lead to problems. Conversely, be selective and choose someone with excellent references, a proven track record and expertise. If you hear significant or consistent negative things about a contractor from references don't ignore them. While every one seems nice at first, go with the facts you hear and see they seem legitimate.
While you should be cautious of roofing contractors who do not provide references, some roofing contractors may just be starting out. If references are not provided, you can check with the Better Business Bureau to see if any complaints have been filed against the contractor. You should also make sure that the contractor is insured (worker's compensation policy as well as liability coverage), as you may otherwise be liable for any injuries that workers incur at your home. You may also want to discuss a good workmanship warranty with the roofing contractor as a safeguard against any faults with the construction. When you begin to discuss your job, be sure that you receive a written estimate, including a listing of the materials that will be used and the manufacturers' warranties. The estimate should include not only the cost of materials, but also the costs associated with preparing the roof (either to remove the old roof or prepare for laying over the existing roof), as well as the costs of permits and clean up. Finally, if your job requires a real specialist find some one that has done a similar type of job.
