Is it time to replace your flat roof?

The lifespan of a flat roof depends largely on the materials used, the quality of the maintenance performed and the severity of the local weather conditions. Depending on these factors, the lifespan can vary from 15 to 30 years. Are you wondering if your roof needs to be replaced or if it’s still in good shape?

At René Perron Couvreurs, we have the equipment and expertise to conduct flat roof inspections for properties in Montreal and the surrounding areas. Keep reading to learn about the signs that your roof may need to be replaced.


There’s significant damage to the roof, and it’s more than 15 years old

If your roof is relatively new and has minor damage, it’s probably more economical to repair the problem area than invest in an entirely new roof. For example, if your asphalt roof has some granule loss or your elastomeric membrane has a few folds, repairing these problems is probably the best option. However, if your roof is more than 15 years old, these issues will only worsen and grow more frequent over time.

There’s significant damage to one or more areas

If only one area of your roof is significantly damaged, repairing it may make the most sense. However, if the issue compromises the structural integrity of your roof or there are several problem areas, replacement may be the better option. Standing water, for example, could indicate that your building is structurally unsound due to rafter rot or a crumbling foundation. In this situation, a thorough inspection of your roof will identify the source of the problem.

There are several leaks in specific areas

A leaky roof can be the result of neglected maintenance, exposure to inclement weather, standing water or improper installation. If your roof has several leaks, it’s almost always a good idea to replace the entire thing rather than repair each individual problem area. Replacement is also the best option if there are various damaged areas all over the roof.

There’s a hidden leak, and your roof is more than 15 years old

Some roof leaks aren’t easy to locate. If you can’t identify where a leak is coming from, it may be better to start fresh.
