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.

Property Owners & Managers Ask Us

Is it possible to reduce the cost of a roof replacement?

One of the most effective ways is reusing your existing insulation. If it's dry and structurally sound, keeping it in place eliminates disposal costs, reduces material spend, and speeds up the install. We saved one client over $16,000 on a single project this way. At Videl Roofing, we're always looking for ways to help local Ontario property owners and building managers keep costs down without cutting corners on quality.

How do I budget for a major roof replacement on a commercial property?

Start with a capital expenditure plan that accounts for your roof's current condition, its estimated remaining lifespan, and the full cost of replacement including materials, labour, and potential insulation upgrades. Planning ahead lets you phase the expense instead of reacting to an emergency.

Why do commercial flat roofs fail prematurely?

Download our State Roofing Report for Ontario. In it we studied 15 commercial and industrial flat roofs across Ontario and found 58 active failure points. The top causes were UV degradation, membrane aging and delamination, and thermal expansion. But the real issue behind all of them was deferred maintenance.

What makes industrial roofing different from standard commercial roofing?

Industrial facilities typically have larger roof spans, heavier rooftop equipment, more penetrations, and stricter operational requirements around downtime and safety. The membrane selection, drainage design, and installation logistics are more complex than a standard retail plaza or office building.

What's the best flat roof system for commercial buildings in Ontario?

It depends on your building type, your budget, and how long you plan to hold the property. Modified bitumen is the most common choice for its durability and repairability. TPO and PVC offer strong chemical resistance and energy efficiency. BUR systems are still a solid option for buildings that need heavy-duty performance.
