Not necessarily. You may only need repair work. The best way to determine the problem is to call in a professional roofing company for an evaluation.They’ll advise you on the most viable and cost-effective course of action

Signs of problems are most likely in roofs that are fifteen years or older.

Look for:

• loose or missing shingles
• damaged flashing – pieces of metal or roll roofing wrapped around vent pipes, chimneys and adjoining walls to prevent water seepage and leakage
• buckling and curling – hingles that are bent up in the middle or turned up at the corners
• blistering and rotting – bubbles, caused by moisture in the shingle, appear on the surface of asphalt roofing

These problems can usually be fixed without replacing the roof. The key is to find them early and have a qualified roofer deal with them immediately.

Ask friends, family and neighbours for recommendations. Contact the Toronto Construction Association, The Greater Toronto Home Builders Association, Better Business Bureau, Scarborough Chamber of Commerce, Registry of Proffesional Contractors of Ontario, and BILD.

You want to establish the contractor’s professionalism and high standards of quality.

• Does your contractor carry workman’s compensation, liability protection and insurance against
• How long has your contractor been in business?
• Does the company have a solid reputation for excellence?
• Will your contractor guarantee job satisfaction? Ask for references.
• Does your contractor use only first quality materials?
• Are your contractor’s staff trained, licensed roofing professionals?
• Will your contractor give you written warranties for labour and materials?
• Will your contractor stand behind the work after the project is completed?
• Can you reach your contractor 24 hours a day, 7 days a week?

There are three basic types of shingles.

• Asphalt Composition tiles are the most popular because they are relatively inexpensive and easy to install. Most home owners choose asphalt shingle, as its life expectancy is 20+ years.
• Premium asphalt shingles provide a more distinctive appearance and carry a longer manufacturer’s warranty. They come in many unique styles which are more attractive, but also more expensive, than the basic asphalt tile.
• Cedar shingles and shakes are listed in the Green Consumers Guide as being completely renewable. They are very attractive; however, their higher cost makes them a less popular choice.

Check that the terms of your contract are being carried out.

• Did the job begin when your contractor said it would?
• Is it progressing on schedule?
• Are the roofing materials the brand you were guaranteed?
• Is the work being handled in an efficient, professional manner?
• Is the contractor available to answer questions or tend to your concerns?
