Flat Roof Replacements
Watertite Roofing specializes in full flat roof replacements using advanced materials like Duro-Last and Goliath Roofing Systems. Our process includes moisture testing, insulation upgrades, and precision installation to ensure long-term durability. Commercial and industrial clients benefit from energy-efficient solutions that reduce cooling costs and meet sustainability goals.
Metal Roof Retrofit
Our low-slope metal roof retrofit services use the Duro-Last system to enhance existing roofs. This cost-effective solution eliminates leaky seams and extends roof lifespan by encapsulating corrugated metal structures with a monolithic PVC membrane, ideal for industrial facilities.
Waterproof Deck Solutions
Watertites vinyl decking systems provide durable waterproofing for patios and outdoor spaces. Using DeckRite membranes, we ensure superior protection against leaks while enhancing aesthetic appeal, with installations designed for minimal maintenance and maximum longevity in residential and commercial settings.

Report
During a heavy rain event, the roof leaked and one of the tenant was concerned about the leak. I called Watertite Roofing and they were on the roof to patch the leak by end of the same day. In the meantime, they did an assessment of the roof and provided a quotation within days for the replacement of the roof. Once the quotation was approved, Watertite Roofing promptly began to replace the roof the following day. The foreman on site for Watertite Roofing was considerate of intrusion to the businesses and their clients. The site foreman was approachable and made changes requested by the landlord

After doing a lot of research on possible solutions for renewing an existing 35yr old low pitch corrugated metal roof on a pre-eng industrial building; a membrane overlay system was chosen as the most effective from a performance, cost and warranty standpoint. After engaging 3 local firms for proposals, it quickly became apparent that Watertite was by far the best solution to meet our needs. Their rep (Zak) was very easy to work with, maintained great communications, and was very professional/responsive to any questions or communications I had. Through the whole process (survey, quotation, project

As the VP on the board of directors for our co-op apartment building in Hamilton for only the last 8 years, I was not involved in the initial decision to purchase a replacement solution for our, now, 60 year old building and therefore cannot comment on time lines involved.
However, a few years ago, we felt the need to make sure it was working as it should and had a Watertite manager come to do an appropriate inspection, which resulted in his assurance that all was as it should be, which also gave me the opportunity to get a deeper understanding and appreciation of the Duro-Last product installed
