ASPHALT SHINGLES

Our line of products is guaranteed to last 25, 30, 35, 40 years,
to life.

Some problems may naturally occur due to the rigours of our North American climate. It is, therefore, important that your home’s roof covering be inspected before the expiry of your guarantee.

An overall roof covering project involves several steps:

• The removal of existing shingles
• Inspection of roof structure and wood or tinplate modifications    
that may be required
• Inspection of ventilation system and installation of roof ventilators
• Installation of a waterproof membrane
• Installation of plates
• Installation of shingles
• Finishing
