|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.

Grand Valley Roofing & Coatings Inc. invests a great deal of time and energy to ensure all our employees have the training necessary to work in a safe manner. We fully comply with the federal, provincial and local legislation. As well, we have developed our own health and safety policies.

| WSIB's Health & Safety Excellence



The program integrates the strengths of our previous voluntary programs (Small Business, Workwell and Safety Groups) into a single health and safety program with more service and delivery options, as well as rebates and recognition, for workplaces. The program connects businesses of all sizes with WSIB-approved providers to help them develop a program that is suitable for their business. It’s designed as a roadmap for employers, taking them from awareness of health and safety laws to developing a complete program or management system based on best practices in health and safety.

Ontario Industrial Roofing Contractors Association (OIRCA) Comes to the Rescue…Before and after the Arson!


Reprinted from OIRCA's Member Bulletin: 2019-09, November 27, 2019

Just imagine a charitable foundation that acquires a new facility in Cambridge Ontario to help those in the community with addiction problems. They plan a major renovation which includes adding a second floor to their new building. Of course, they are going to need a new roof, but their budget is tight, and they are looking for support. Sounds like a perfect candidate for Rooftop Rescue.


And so, the OIRCA Foundation leaps into action. We find a local member willing to donate the labour and a member who is prepared to contribute the materials. The roof is a steep sloped shingle roof, but it is December, so winter is fast approaching. We decide to close the building in with an ice and watershield membrane with the intent of installing the shingles the following spring. Phase one of the roof gets completed meaning the inside trades can move into the building


Spring 2019 arrives and OIRCA Active Member Grand Valley Roofing & Coatings Inc. of Cambridge is getting ready to start the application of the shingles on the House of Friendship’s new facility. It’s May 1, 2019 and word spreads quickly. At approximately 3:30 a.m. that morning there is a fire at the construction site. It is serious.
