21+ Years Roofing Grenville
Before Grenville Roofing & Maintenance existed, the founder spent 8 years installing roofs for other contractors in Grenville. That experience taught one clear lesson: homeowners deserve straight answers and solid installs. That's what we built this company around.
Every installer on our crew holds manufacturer training certifications. We send our guys to GAF, Owens Corning, and CertainTeed training programs annually. The industry evolves. Our skills evolve with it.
Ask any of our 142+ past customers and you'll hear the same thing: they were honest, they did good work, and they cleaned up after themselves. We'd rather be known for that than for a clever marketing campaign.
