Most Roof Damage Happens Long Before the First Leak Shows Up
Watch Kirby Hewines as he inspects a commercial flat roof in Welland, Ontario. What started as a routine inspection uncovered issues that had nothing to do with the membrane itself — corroded gas lines without proper paint protection, inadequate blocking around gas line penetrations, and rotten sleepers under rooftop HVAC units.

Other Roofers Recommend Videl
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.

Expert advice on commercial roofing, repairs, and maintenance.
Can I reuse my existing insulation during a roof replacement?
In many cases, yes. If your existing insulation is dry and structurally sound, reusing it can save thousands on a replacement project. We assess insulation condition during every Roof Condition Report and recommend reuse when it makes sense — like a recent project where we saved a client over $16,000 by keeping their existing insulation in place.
How does Niagara's climate affect commercial flat roofs?
The Niagara Region sits between two Great Lakes, which means lake-effect snow, persistent moisture, and aggressive freeze-thaw cycles from late fall through early spring. These conditions accelerate membrane wear, cause ice damming, and put extra stress on drainage systems and penetrations. Flat roofs in Niagara need proactive maintenance to avoid premature failure.
How often should a commercial roof be inspected in Niagara?
Twice a year at minimum — once in spring to assess winter damage and once in fall before snow season. Properties with rooftop HVAC units, skylights, or elevator shafts should be checked more frequently since penetrations are the most common leak source on flat roofs. Most manufacturer warranties also require documented maintenance to stay valid.
What types of flat roof systems do you install and repair?
We specialize in 2-ply modified bitumen, BUR, and select single-ply systems for commercial and industrial buildings. Our recommendations are based on your building type, long-term plans, and budget — not a one-size-fits-all approach.
What types of commercial buildings do you service in the Niagara Region?
Warehouses, manufacturing facilities, retail plazas, office buildings, hospitality properties, and institutional buildings across Niagara Falls, Welland, Thorold, Niagara-on-the-Lake, Fort Erie, Pelham, Grimsby, Lincoln, Port Colborne, West Lincoln, and Wainfleet. We also offer specialized solutions for food processing facilities and property management companies.
