They did a great job on our roof and recapping our front door. A few years later a leak showed up. They came out had 2 options. Tried the first one and it worked till the following year. Then when it cam back, I called, they showed up with plan B and so far its perfect.
Easy to deal with, they are competent and they listend to my Concerns.
I will continue to recommend.

I recently had my eavestroughs replaced by Ace 1 Quality Roofing, Siding & Eavestroughs at my home in Welland, and I’m extremely happy with the results.
Dan and his crew arrived on time, explained everything clearly, and got the job done efficiently without cutting any corners. The new eavestroughs look great and work perfectly — no more overflowing or drainage issues.
It’s clear they take pride in their work and care about their customers.
I would definitely recommend Ace 1 Quality Roofing, Siding & Eavestroughs to anyone in the Welland area looking for reliable, high-quality exterior work!
