Roof Maintenance in Chambly and the Surrounding Area

Why Regular Flat Roof Maintenance Matters

A flat roof is constantly exposed to harsh weather, the weight of snow, freeze-thaw cycles, and UV rays. Without regular maintenance, minor problems can lead to water infiltrations, mould, and structural damage. Preventive maintenance performed by ML Pro Toitures catches weaknesses before they worsen, maximizing the service life of the roof.

When Is Maintenance Necessary?

Quebec Master Roofers (AMCQ) recommends a minimum of two inspections per year: in the spring, after the snow melts, and in the fall, before the freeze. An additional inspection is also advisable after any severe weather event (windstorm, ice storm, or heavy snowfall).
