As a local roofing company in Grimsby, we have been helping homeowners across the area get their roofs done right. Whether you are on Grimsby Mountain, near Grimsby Beach, in Casablanca, or in one of the newer builds in Dorchester Estates, our team arrives on time, works carefully, and leaves your property clean. We handle everything from a straightforward roof repair to a full replacement, and we back every job with a workmanship guarantee.
Grimsby sits along the Niagara Escarpment and the Lake Ontario shoreline, which creates a roofing environment that demands more than builder-grade shingles and a quick install. Lake-effect wind coming off the lake puts real uplift stress on roofs in the lower parts of town. Properties on Grimsby Mountain face their own exposure challenges. We use materials selected for this area, including algae-resistant shingles, proper ice and water shield, and high-wind fastening on every install.

Why Grimsby Homes Need a Different Roofing Approach
Grimsby sits at the base of the Niagara Escarpment with Lake Ontario directly to the north. This geography creates two very different roofing challenges depending on where your home is. Properties along the lakeshore and through Downtown Grimsby get continual wind off the lake, which drives moisture under shingles and puts real uplift pressure on roof fastening. Homes higher up on Grimsby Mountain face the opposite problem: elevation, heavier snow load, and colder temperatures that extend the freeze-thaw cycle.
Algae growth is a widespread issue in Grimsby because of the lake humidity. We install algae-resistant shingles on every residential roofing job here. We also use proper drip edge, ice and water shield on all eaves and valleys, and correct roof ventilation details to prevent the moisture buildup that causes premature roof failure.
Full-Service Roofing for Grimsby Homes
From a small roof repair in Casablanca to a full new roof installation on an executive home on Grimsby Mountain, we handle every project with the same level of care. Here is what we offer to homeowners across Grimsby.

Green Peaks wasn't able to help with my specific location, but Lewis went above and beyond. He was incredibly kind and gave me a ballpark quote so I'd know what to expect when looking elsewhere. Highly recommend their customer service!
Had my Flat roof done the other day, I am really happy with the work , Chris and his crew were very professional! Prompt! Most importantly the job was done correctly! They clean up very well after the job was done! I recommend Green Peaks Roofing to anyone that needs there roof redone.. Good work Chris and your crew!
Chris did an outstanding job fixing my roof! He was very professional, efficient, and clearly knew his craft. I’m grateful for his expertise, and now I have peace of mind every time it rains!
We recently had the insulation in the attic topped up to modern standards and new shingles installed by Green Peaks and couldn’t be more satisfied. Chris and the whole team were very professional and did both parts of the work on schedule including a thorough clean up. The 25 year warranty on workmanship and 50 years on shingles gives us a great sense of security. I would highly recommend Green Peaks to anyone looking to have roof work done. Thanks Tom Whattam
I just had some fascia and soffit repaired by Green Peaks. They were easy to communicate with, honest, and offered a very professional service. They will be my first call for any future roofing needs
We used Green Peaks Roofing for our patio roof. Chris and Brandon arrived when they said they would. They showed professionslism and excellent workmanship. We were kept informed of work being done. After the job was completed as outlined, the clean up afterwards was spotless. The quote was exactly as he stated with no changes. We appreciated their sense of humour and would recommend Chris and his employees very highly. Would definitely call upon them if a need arises.

Yes. If you have an active leak or storm damage that cannot wait, call us directly and we will arrange a same-day visit. We handle emergency roof repair across all of Grimsby and the surrounding Niagara Region.
Yes. Green Peaks Roofing is fully licensed and insured for all roofing work in Ontario. We carry WSIB coverage and full liability insurance, and we are happy to provide proof of both before any project begins.
Yes, we recommend algae-resistant shingles for most Grimsby homes. The lake humidity coming off Lake Ontario creates ideal conditions for algae growth on standard asphalt and fibreglass shingles. Algae-resistant shingles carry a small upcharge but meaningfully extend the life and appearance of your roof in this climate.
A properly installed asphalt shingle roof in Grimsby typically lasts between 20 and 30 years depending on shingle grade and roof ventilation quality. The freeze-thaw cycle and lake-effect wind can shorten that lifespan if the roof was not installed with proper ice and water shield, underlayment, and high-wind fastening. We install to manufacturer specifications on every job.
