Bill Mabry from Owens Corning Roofing tells Designing Spaces why finding a contractor for roof repairs and installations is so important. He states that even the best roof will not work effectively if it is not installed properly. Homeowners should take their time in selecting and getting to know the contractors they’re considering for their roofing job. Bill lists standards that homeowners should abide by when selecting a contractor. He states that the homeowners should make sure the roofing contractor has all necessary state licenses and accreditations, references and a good work history, is insured, and can explain all of the steps for the project.
