Your flat roofer in Lachine
A leaking flat roof in Lachine? Clinique de la Toiture FCA has worked in the borough since 1996, on repair, replacement and maintenance of flat roofs.
Lachine has a feature few boroughs share: its building stock mixes converted industrial buildings along the canal, plexes from several eras and commercial properties. Three construction types, three ways of ageing, and rarely the same membrane from one roof to the next.
What we most often find on Lachine roofs
- Stacked membranes, sometimes three layers built up over decades
- Original drains undersized for today’s rainfall
- Cracked parapet flashing on the older buildings
- Waterlogged insulation under a membrane that still looks fine
That last one costs the most when it goes unnoticed: a membrane that looks good can hide dead insulation, and redoing only the surface restarts the countdown.
White membrane is required for a major repair
As in most Montreal boroughs, a major flat roof repair must use a white material to limit heat islands. That is a permit constraint, not a preference.
- No open flame on the roof. TPO is heat-welded with a hot-air iron, no torch and no toxic fumes.
- 20 to 25 years of service life in Quebec, with a 20-year manufacturer warranty.
- Reflective white surface that cuts summer cooling load.
- Every seam is hot-air welded, giving continuous watertightness.
The other membranes we service
Elastomeric membrane
A granule-surfaced two-ply membrane installed with a torch, very common on the existing stock. It is a separate niche, served by other companies. We repair and maintain it.
Asphalt and gravel
A sturdy multi-layer system, less and less installed. It lasts 15 to 20 years and needs more maintenance.
EPDM
A darker single-ply membrane, very durable, but it absorbs heat instead of reflecting it.
In addition, Clinique de la toiture FCA’s promise is support from A to Z in your project. As experienced roofers, we want to advise our new clients in Terrebonne as best we can on what constitutes a successful roof renovation, and offer new roofing system options for your roof.
We are not in the business of advising a roof replacement when a repair is possible.
On the other hand, in the event that the complete renovation proves to be inevitable, we have a policy of transparency at all times as to the size and the cost of your project.

What it costs
Count on $11 to $16 per square foot for a TPO roof, materials and labour. On an older building, the state of the deck and the number of layers to strip move the number. We never give a firm price without going up on the roof first.

In most cases yes. Adding one more layer traps the existing moisture and adds weight.

It cannot be seen from above. We take a core sample at a targeted spot before recommending a full replacement.
