St. Catharines sits on the Niagara Peninsula between Lake Ontario and the Niagara Escarpment, an area known for its orchards, vineyards, and the Twelve Mile Creek valley. That same geography brings humidity off the lake, a longer freeze-thaw season, and wind exposure that wears on roofs faster than in many other Ontario cities. We use materials built for this climate, including algae-resistant shingles, proper ice and water shield, and quality underlayment on every install.

Why St. Catharines Homes Need a Different Roofing Approach
St. Catharines sits in a unique spot on the Niagara Peninsula, caught between Lake Ontario to the north and the Niagara Escarpment to the south. The lake pushes humidity and wind into neighbourhoods like Port Dalhousie and the North End year round, while the escarpment side of the city sees heavier snow load and a longer freeze-thaw season. Roofs here take a different kind of wear than roofs further inland.
Algae growth on shingles is one of the most common complaints we hear from St. Catharines homeowners, especially in older neighbourhoods like Merritton and Grantham where mature tree cover holds in moisture. We install algae-resistant shingles on every residential roofing project in St. Catharines, and we use proper drip edge and roof ventilation details to keep moisture from building up where it should not.

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.
