Watch what happens when ponding water goes unchecked
In this reroof project, the building had serious ponding water pooling across the membrane before we started. Our team lowered and sump-drained every roof drain to completely redesign the water flow. After three straight days of rain, we came back to check — not a drop of standing water anywhere on the new roof.

Mark Pallin is Senior Manager at Sanyo Canadian Machine Works, a manufacturing facility that had been dealing with recurring roof leaks for years. After eight ceiling tiles collapsed onto office desks overnight, he called his brother — a retired professional roofer — for a recommendation. The answer was Videl.
“We came into work one morning after a big rainstorm and eight ceiling tiles had collapsed onto the desks, totally saturated.”

Expert advice on commercial roofing, repairs, and maintenance.
How can I reduce the cost of a commercial roof replacement in Ajax?
One of the biggest cost savings comes from reusing your existing insulation. If it’s dry and structurally sound, there’s no reason to tear it out and send it to a landfill. Reusing insulation means fewer disposal bins, less material cost, and a faster install. We saved one client over $16,000 on a single project by keeping their existing insulation in place.
What are the warning signs that my flat roof needs immediate attention?
Bubbling or blistering in the membrane, pooling water that doesn’t drain within 48 hours, visible cracks around penetrations, and ceiling stains inside your building. Any one of these means moisture is already getting in. The longer you wait, the more damage it does to your insulation and decking.
How often should a commercial roof be inspected in Ajax?
Twice a year at minimum. Once in spring after winter damage and once in fall before snow season. Buildings with rooftop HVAC units or skylights benefit from more frequent checks. Most manufacturer warranties also require documented maintenance to stay valid.
What types of commercial buildings do you service in the Durham Region?
Retail plazas, industrial warehouses, multi-tenant commercial buildings, office properties, and institutional buildings across Ajax, Pickering, Whitby, and Oshawa. We also provide specialized roofing solutions for food processing facilities and property management companies overseeing multiple buildings.
Where can I find data on commercial roofing costs and trends in Ontario?
We published a Commercial Roofing Report for Ontario that covers current pricing trends, material costs, labour rates, and what property managers across the province are spending on repairs and replacements. It’s free to download and built to help you benchmark your own roofing budget against real Ontario data.
