We Excel at Flat Roofing Repair and Installation

Flat roof installation requires a specialized approach compared to pitched roofs. If you need a flat roof installed, you need a team that has the experience and knowledge to get the job done right.

Flat roofs, by nature of not having a slope, are unable to displace water as easily as sloped roofs, requiring alternative solutions like scuppers, roof drains, or a drip edge detail.

Since water is much more prone to resting on top of your flat roof compared to a pitched roof, ensuring that your roof is impermeable is critical to preventing water damage.

Why We’re Unique Among Roof Repair Companies in Toronto

There are many Toronto roofing companies, and we understand that searching out the right one for your home can be a struggle.

Dominion is a local roofer you can rely on – we offer the best services and guarantees in the business.

Roofers in Toronto That Pride Ourselves on Customer Service

But with Dominion, we value our customer, their time, and their budget above all else. We make sure that all your roofing needs are satisfied – whether that’s replacing a few missing shingles or a comprehensive repair of your entire roof.
