Plazas, warehouses, multi‑tenant buildings and industrial facilities. TPO, EPDM, and 2‑ply SBS with clean staging, safety‑first crews, and warranty registration.
When a flat roof reaches end‑of‑life, commercial roof replacement Toronto stops the cycle of emergency patching and tenant disruption. Our process begins with a condition review and, where helpful, core cuts or moisture scans.
We specify an assembly that fits the building and your maintenance realities: two‑ply SBS modified bitumen for most multi‑tenant sites that see regular foot traffic and future service work, or single‑ply membranes such as TPO/EPDM for very large, simple layouts where wide sheets lower initial cost.
Toronto’s freeze–thaw makes drainage non‑negotiable, so we correct slope with tapered insulation, add crickets behind units and parapets, and re‑position or add drains where ponding develops. Penetrations—HVAC curbs, vents, and stacks—are re‑flashed with manufacturer details, and edge metal is upgraded to current wind ratings.
Scheduling is designed around business hours and safety. We stage work so access stays open, use warning lines and tie‑offs, and complete daily “dry‑in” so no area is left exposed overnight. You receive a photo log documenting deck repairs, membrane seams, and terminations, then a close‑out package with warranty registration.
For owners and property managers, the goal is simple: a clean, code‑compliant system that reduces service calls for years. If budgets require phasing, we prioritize the worst zones now and plan the balance for your next fiscal window—without compromising watertightness in the meantime.
Typical timelines: small retail bays and offices are usually completed in 1–3 days depending on layers, curb details, and weather. Larger warehouses or multi‑tenant buildings can span 3–7 days with staged access and safety lines.
What speeds things up: clear roof access, early bin placement, and confirmed crane times. We coordinate with site managers to keep customers and tenants moving safely.
What can slow a job: hidden wet insulation, deck rot, or surprise penetrations. We document these with photos and give options so you can approve the most efficient fix.
