Roofing is a complicated and demanding trade. A professional roofing contractor must have knowledge of materials and building technology and a trained and skilled work force to give the best possible service to his/her customers.

To get the job done right the first time and to avoid costly repairs later, make sure you insist upon a professional roofing contractor.

Before you decide to contact a professional roofing contractor you need to prepare for the visit. Write down all the questions you may have, what type of look you might prefer, type of roofing materials you like, a house you've seen, colors you like, problems you might have with a schedule.

Be sure you're comfortable with the contractor and the roof system he is suggesting. A professional contractor is going to be happy to answer your questions.

What to look for in a professional roofing contractor:

• How many years' experience does the roofing contractor have?
• Can I be supplied with references from several years past to establish long-term satisfaction?
• Check customer references. Ask for the names of several customers with roofs similar to yours.
  Will they provide references locally?
• Is it always best to go with the "low-bidder" or will this cost me more in the end?
• How well has the contractor explained the process of my project as well as what I can expect
  during that time? Do I know what is expected of me?
• Will the contractor care for my property as if it were his own? Will the crew show respect for my
  neighbors during the project?
• Is the contractor, in fact, properly and currently insured with Workmen's Compensation and general liability insurance for roofing? (Certificate should come in the mail directly from the insurance carrier.)
• Is the roofing contractor a part of the project from start to finish, or is he just a sales person who
  collects a check at the end?
• When will the contractor start and finish?
• Where is the exact business location? (Get this information even if they work out of their home.)
• How long will the installation/workmanship warranty be?
• The amount of down payment required? (Get this information in percentage and actual amount.)
• Insist upon a written proposal. You'll get it from a professional roofing contractor. Examine it to make sure you think it is complete and fair.
