Flat Roof Replacement
A Strategic Investment — Not Just an Expense
At Videl Roofing, we don’t jump to replacement unless it’s the right move. We’ve spent decades repairing and replacing flat roofs across Ontario, and one thing is clear: timing is everything.
A roof that’s failing slowly can still cost you big — in interior damage, insurance claims, business disruptions, and tenant complaints. But replacing a roof too early? That’s throwing away years of potential value.
That’s why we created a smarter, data-backed approach.

How long does a flat roof last?
The lifespan of a flat roof can vary depending on the materials used and how well the roof is maintained. On average, you can expect a flat roof to last between 10 to 25 years. Some modern roofing materials can last even longer. Regular inspections and timely repairs can significantly extend your roof’s lifespan.
What is the best way to maintain a commercial flat roof?
Maintaining a commercial flat roof involves regular inspections (at least twice a year and after major weather events), keeping the roof clean and free of debris, promptly repairing any damage or wear, and ensuring the drainage system is working well to prevent water pooling. It’s a good idea to work with a professional roofing service for regular maintenance to catch potential issues early and keep your roof in top shape.
