Commercial Roofing
Asphalt shingle roofing for commercial buildings with sloped roofs.
Toitures Boulet installs and replaces asphalt shingle roofs on sloped commercial buildings across the region. We use the same proven system as on our residential roofs, with job-site planning adapted to a commercial setting. To be clear: we do not install membrane systems on commercial flat roofs. Our work respects schedules and minimizes disruption to your operations.
Problems we solve
- Shingles lifted, cracked or torn off by wind on your commercial building's sloped roof.
- Granules in the gutters and end-of-life shingles leaving the building exposed to leaks.
- Leaks around flashings, vents or valleys threatening your premises, inventory or equipment.
- Need to coordinate work without interrupting your business operations.
- Insurance, municipal or landlord requirements to meet for the re-roof.
Shingle roofing for commercial buildings
Many commercial buildings in the region have a sloped roof, whether they're storefronts, offices or mixed-use buildings. On these roofs, asphalt shingles remain a proven, affordable and durable choice. Toitures Boulet brings the same craftsmanship it uses on residential roofs, with job-site planning adapted to a commercial setting.
The stakes on watertightness are higher on a business property, though: a single leak can damage inventory, floors and expensive equipment. That's why every commercial roof we install is designed as a complete system, from the deck to the flashings.
A complete system, from deck to flashings
On a full replacement, we tear off the old layers down to the deck, inspect the plywood and replace any damaged sections. We then install Ice & Water Shield at the eaves and in the valleys, synthetic underlayment across the rest of the surface, and IKO or Owens Corning architectural shingles laid to the manufacturer's specifications.
Flashings around chimneys, walls and penetrations are replaced with new ones, and ventilation is checked to protect the deck and extend the life of the shingles.
Properly installed and maintained, a quality architectural shingle delivers 25 to 35 years of service in our climate. It's a solid, predictable investment for a commercial building owner.
A job planned around your operations
We understand the particular constraints of commercial jobs: protecting entrances and traffic, scheduling to minimize the impact on your operations, and coordinating with tenants. We agree on a clear timeline with you before the work begins.
To keep your roof in good shape after the install, we also offer shingle roof inspection, preventive maintenance and repair.
Our workmanship warranty and liability insurance meet the requirements of major property managers. We'll provide whatever documentation you need to open a vendor file with us.
