Why PVC for a new-build roof in Northern Ontario?
PVC suits a new-build flat roof in Northern Ontario because its seams are welded with hot air into one continuous sheet, it does not absorb standing water, and it stays flexible in the cold.
PVC (polyvinyl chloride) is a single-ply thermoplastic membrane. Seams are the weak point on most flat roofs, and on a PVC roof they are fused rather than glued or taped. That matters in Sault Ste. Marie, where winters are long and snow can sit on a roof for months. PVC is not the right answer for every building, so here is how it compares with the other systems we install.
| System | Layers | Where it wins | Where another system wins |
|---|---|---|---|
| PVC | Single ply, hot-air welded seams | Welded seams, reflective white surface, handles ponding water | One layer; modified bitumen is tougher under heavy foot traffic |
| TPO | Single ply, hot-air welded seams | Welded seams and a reflective surface, often at a lower cost | PVC has the longer track record of the two |
| 2-ply modified bitumen | Base sheet plus cap sheet | Toughest underfoot, two layers of protection | Heavier, and a dark surface absorbs more summer heat |
| EPDM | Single ply rubber | Very flexible in cold weather | Seams are taped or adhered, not welded |
Our PVC vs TPO guide compares the two welded membranes in more detail, including grease, chemicals and cost.
How is a PVC roof installed on a new build?
On a new build, the PVC membrane goes down over insulation on the new roof deck, the sheets are fastened or adhered to suit the system design, and every overlap is welded with hot air.
New construction is the best time to get a flat roof right. There is no old membrane to tear off, and every detail can be built to the manufacturer's specification from day one. On a Sault Ste Marie PVC roofing job, flashings at parapets, drains, vents and curbs are made from the same PVC and welded to the field membrane, so there are no dissimilar materials to pull apart over time. Industry guidance from the National Roofing Contractors Association makes the same point about single-ply roofs: seam quality and flashing details decide how long the roof lasts.
What does the 30-year labour and materials warranty cover?
This Sault Ste Marie PVC roofing project carries a 30-year warranty on labour and materials, which is the maximum warranty OYH Roofing can offer on any system.
On this Sault Ste Marie PVC roofing job, both the membrane and the workmanship are covered. The exact coverage, and what the owner has to do to keep it valid, is set by the written warranty terms. That usually includes regular inspections and keeping records of any work done on the roof. Ask for the warranty document for your project and keep it with the building records.
How do you maintain a PVC roof in Northern Ontario?
A PVC roof needs an inspection at least twice a year, in spring and fall, plus a check after major storms. For Sault Ste Marie PVC roofing, the spring visit matters most because of the long snow season.
| When | What to check |
|---|---|
| Spring, after the snow melts | Seams, flashings, drains, any damage from ice or snow load |
| Fall, before winter | Clear drains and scuppers, check flashings at curbs and parapets |
| After major storms | Damage from ice, fallen branches or wind-driven debris |
| Every rooftop service visit | Crews stay on walkway pads; keep oils and grease off the membrane |
Owners and residents should not walk the roof themselves, especially in winter or wet weather. Book the inspection and let a roofing crew do it with proper fall protection. We offer inspections to every Sault Ste Marie PVC roofing client.

How long does a PVC flat roof last?
A PVC flat roof can last 30 years or more when it is installed as a full system and inspected twice a year. The Sault Ste. Marie residential roof carries a 30-year warranty on labour and materials, which reflects that expected service life. Blocked drains, punctures from foot traffic and skipped inspections are what usually shorten it.
Is PVC a good choice for flat roofs in Northern Ontario?
PVC is a good choice for flat roofs in Northern Ontario because its seams are welded with hot air, it does not absorb standing water, and it stays flexible in cold weather. Modified bitumen is tougher under heavy foot traffic, so the best system depends on the building and how the roof is used.
What is a PVC roofing membrane?
A PVC roofing membrane is a single-ply sheet of polyvinyl chloride used on flat and low-slope roofs. The sheets are rolled out over insulation and the overlaps are welded with hot air, which fuses them into one continuous watertight surface. Flashings at drains, vents and parapets are made from the same material.
What does a 30-year labour and materials warranty mean?
A 30-year labour and materials warranty means both the membrane and the workmanship are covered for 30 years, subject to the written warranty terms. Those terms usually require regular inspections and records of any rooftop work. On this project it is the maximum warranty OYH Roofing can offer on any system.
