Professional Flat Roofing in Cambridge

Grand Valley Roofing & Coatings Inc. was established in 1999 under the name of Triple D Roofing, which had started out as a residential slope and small flat roofing installer. The company soon started to build a solid reputation in the local market and began to expand into the commercial, institutional and light industrial markets. In 2005, the company decided to change to the present name of Grand Valley Roofing & Coatings Inc.

Our Goal

About Our Warranty

As a member of the Canadian Roofing Contractors Association (CRCA), Grand Valley Roofing and Coatings Inc. provides building owners the assurance that their roof was installed with high-quality workmanship.

This warranty provides the following workmanship protection for two years:

The roofing application has been performed in compliance with approved plans, specifications, and changes. Grand Valley Roofing will repair, at no expense to the owner, any deficiencies that are a result of workmanship issues

Note: No roofing warranty covers "acts of God" such as ice storms or high winds. Therefore, it is important that the building owner carry insurance for these instances. Also, the manufacture may provide a warranty on the material used on the roofing installation. However, these often do not include the labour or metal work.
