When a flat roof starts leaking, most building owners assume they're facing a full tear-off: dumpsters, exposed decking, weeks of disruption, and tenants calling about the noise. There's another option most SW Ontario owners have never been offered.
How an SPF Roof System Works
High-density closed-cell polyurethane foam is sprayed directly over your existing membrane after cleaning and prep. It cures into a single seamless surface — no seams, no fasteners, no flashing joints — then gets a protective elastomeric coating that handles UV and weather.
Flat roofs fail at seams, drains, and penetrations. An SPF roof doesn't have seams. Foam self-flashes around every curb, vent, and drain, which is exactly where your current roof is leaking.
What You Avoid
No tear-off means no dumpsters of old membrane going to landfill, no days where your building is open to the sky, and dramatically less disruption to operations underneath. Installation is a fraction of the cost and downtime of full replacement — and unlike a new membrane, the foam adds real insulation value (about R-6 per inch) on top of your building.
With periodic recoating an SPF roof serves for decades, and Ontario's freeze-thaw cycles — brutal on seamed membranes — are handled better by foam than by any other flat roof system.
Is Your Roof a Candidate?
Most structurally sound flat roofs are. We start with an inspection and moisture scan to confirm the existing assembly is dry enough to coat over. We install SPF roofing anywhere in Ontario — it's one of our flagship large-project services. Request an assessment through the quote form.
