Residential, commercial and industrial roofs

Flat roof specialists in Laval

Our know-how and specialized experience cover the full range of flat roofing systems relevant in Quebec, because a flat roof requires technical expertise and careful attention to the realities of local climate: freeze-thaw cycles, snow loads, episodes of freezing rain, and high winds.

Our specialized flat roofing crews in Laval evaluate the structure, slopes, drains, flashings, and membrane condition on your roof to prevent leaks and extend its service life.

They will help you understand the different types of flat-roof coverings so you can choose according to your needs:

White roofs

An efficient solution to reduce solar heat gain and urban heat islands, white roofs are increasingly used in densely populated areas. Surface cleanliness is essential to preserve reflectance. A maintenance plan is recommended, including light cleaning and joint inspections.

Commercial and industrial flat roofs

A sound commercial or industrial flat roof is essential to your workplace. These roofs demand a robust design and proper maintenance management. Whether for a new installation or to keep your existing roof in good condition, our flat roof roofers in Laval are here to help.

Elastomeric membrane

Often chosen for strong resistance to freeze-thaw cycles, ease of repair, and proven benefits. During reroofing, we optimize slope (toward central or linear drains) and ensure waterproofing continuity. Ideal for durable performance and predictable upkeep.

Rooftop terraces

Rooftop terraces can become a true outdoor haven. We integrate safety measures and a seasonal maintenance program to prevent premature deterioration of the waterproofing layers.

Green roofs (vegetated roofing systems)

Green roofs are gaining in popularity, and with reason. They offer many advantages, including excellent thermal management and strong retention of rainwater and other runoffs, plus the option to cultivate.

Preventive maintenance: two key visits, in spring (after thaw) and in fall (before winter). Drain cleaning, checks of joints and flashings, detection of micro-fissures, etc.

Common issues on flat roofs in Laval

Leaks and open joints

Joints are sensitive points on a roof. With freeze-thaw cycles and partial or constant UV exposure, cracks, fissures, shrinkage, or loosening of sealants can occur. Periodic inspections allow us to intervene before infiltrations occur.

Standing water (ponding)

Insufficient slopes create stagnation zones that accelerate aging. Correcting surface slopes and improving drainage are recommended.

Blisters, cracks, uplift

Linked to vapour pressure, trapped moisture, or thermal cycling. We perform exploratory openings and replace affected sections.

Heavy snow, freezing rain, and overload

In winter, accumulated snow and ice can weigh down the structure and obstruct drains. Do not forget to remove snow or de-ice when there are signs of overload.

Quick FAQ

Do you need a permit to redo a flat roof?

In most cases, yes. Many municipalities require a permit for reroofing. In Laval, confirm your project with municipal services before starting.

When should you plan for a roof renovation?

As soon as the membrane nears the end of its service life or if the insulation is wet. A professional diagnosis helps you avoid repeated repairs.

Winter: what should you do in case of infiltration?

Protect the interior, limit water ingress, and call our team. Depending on the situation, targeted de-icing and a temporary repair can secure the area until the final correction.
