Ontario's commercial and industrial buildings lose thousands of dollars annually through aging flat roofs. Roof coatings extend membrane life by 10–15 years at a fraction of full replacement cost — and reflective versions cut summer cooling bills significantly.
What specialized roof coating contractors provide for Ontario commercial, industrial, and institutional buildings.
White and light-grey elastomeric roof coatings reflect solar radiation, reducing roof surface temperature by up to 40°C. Ideal for warehouses and big-box retail with flat TPO or EPDM roofs and significant cooling loads.
Silicone, acrylic, or polyurethane coatings applied over EPDM, TPO, BUR, and modified bitumen membranes to seal seams, repair flashings, and restore waterproofing without full tear-off.
Full restoration systems that prime the existing membrane, reinforce split seams and flashing with fabric, then apply a waterproof topcoat. Extends roof life 10–15 years at 30–50% of replacement cost.
Ontario's climate requires coatings that maintain flexibility through freeze-thaw cycling. Elastomeric silicone and modified acrylic systems rated for -40°C to +80°C performance. Critical for metal decks and concrete roof slabs.
Rust-inhibiting primers and elastomeric topcoats for corrugated and standing-seam metal roofs. Seals rivet holes, re-caulks seams, and applies UV-resistant coating to extend metal roof life by 15+ years.
Before any restoration coating, a reputable contractor performs an infrared scan to identify wet insulation areas. Wet insulation cannot be coated over — it must be replaced first. Always request the IR report before signing a coating contract.
| Factor | Roof Coating | Full Replacement |
|---|---|---|
| Cost (10,000 sq ft flat roof) | $30,000–$90,000 | $80,000–$200,000+ |
| Life extension | 10–15 years per application | 20–25 years new roof |
| Disruption | Minimal — no tear-off | Major — tear-off, debris removal |
| Suitable if wet insulation < 25% | Yes — replace wet areas first | Not required |
| Energy rebate eligible | Possibly via Save On Energy | Varies by system |
| Best for | Serviceable membrane, budget-constrained | End-of-life membrane, major damage |
Ontario roofing contractors who operate service trucks and material haulers must maintain CVOR lettering on all commercial vehicles. When trucks get resprayed or repainted, CVOR numbers and company identification must go back on before the vehicle returns to Ontario highways. Pre-cut vinyl kits ship next day across Ontario from Port Colborne.
