It's difficult to determine the capabilities and reliability of a contractor just on face value or when he or she approaches you with a printed brochure. In order to select a qualified contractor there are a few steps which are advised in order to be sure that you are getting a fair deal. These include doing a market survey of available contractors and their market credentials, meeting members of the local councils to get their suggestions and then homing in on a manageable list of contractors whom you think can do the job for you. Based on referrals and your meetings, you need to make a checklist of people who qualify for your job. Arrange an interview with them and ask the following questions and try and get a satisfactory answer.

Is the contractor worthy of being given the responsibility for replacing the roof and other structures in the house? Does the claims which he makes as regards past replacement and projects actually relate to his expertise in the field of re-roofing. Can he be trusted? Is he qualified enough to suggest the replacement or repair of the roof? In particular, you need to be sure the contractor understands the following issues.

He must be aware of roof flashing details, how to handle problem spots on building roofs and alternative roof covering products like shingle types, grades, colors, low slope roofing, flat roofing materials, etc. A competent roofer will provide the client with sound advice on products, a reasonable explanation of procedures, and, most importantly, dependable results in the form of a strong and a durable roof.

There are many ways to get a repair wrong, but only one way to get it right. This statement applies to any home improvement or house repair project. The primary concern of any house owner when he or she goes in for roof, window or door replacement is whether the contractor to whom they have awarded the contract is capable and knows their work inside out.
