Copper and standing-seam metal
The pinnacle of metal roofing: 50 years and more, a patina that grows more beautiful with time. Ideal for accents and complete high-end roofs.
Drone survey · Blainville, QC · 45.6733° N, 73.8712° W
Your roof, mapped down to the centimetre.
Before every re-roof, we fly over your roof by drone and produce a complete topographic survey: slopes, ridges, flashing, wear zones. A documented diagnosis, not an estimate by guesswork.

The survey method
Four steps, from sky to last shingle. Every job starts with a map and ends with a roof whose every corner we know.
- 01
Drone flyover
A certified pilot flies over your property at 60 metres altitude and captures several hundred high-resolution photos.
- 02
3D modelling
The images are stitched into a photogrammetric model: exact slopes, surfaces, ridges and valleys, down to the centimetre.
- 03
Documented diagnosis
You receive an illustrated report: wear zones, flashing to watch, potential leaks — with annotated photos.
- 04
Precise intervention
The re-roof is planned on the map, not on the back of a napkin. Fewer surprises, a schedule kept, a firm price.
Materials chosen to last
We install what we would install on our own homes. Four systems, each mastered inside out.
Architectural shingles
The proven choice for Blainville homes: double thickness, 30-year manufacturer warranty, about ten slate tones.
Elastomeric membrane
Torch-applied in two layers for flat and low-slope roofs. Total waterproofing, minimal maintenance.
Natural slate
For character homes: genuine slate installed to the rules of the art, a roof that outlives generations.
Recent projects
Three recent jobs, three maps, three new roofs. Every project is delivered with its final survey.
