Roof Experts installs snow guard systems on commercial and residential properties throughout Thornhill, including the Vaughan and Richmond Hill sides of the community. We work with all roof types — standing seam metal, corrugated metal, metal panels, shingle, and flat roofs.
Thornhill properties face ground snow loads of 1.4–2.0 kPa per NBC 2020. On metal roofs in particular, snow can release suddenly during freeze-thaw cycles — creating a safety hazard above parking areas, entrances, and walkways.
Commercial snow guard installation in Thornhill
We have completed snow guard installations on commercial plazas and retail properties in Thornhill. A common scenario: metal roof installed without snow retention, followed by complaints from tenants or property managers about snow and ice falling onto parking areas and building entrances during winter.
Our specialists calculate the required layout based on roof size, slope, and snow load, then match the snow guard color to the existing roof — no visible contrast, clean appearance.
“We did not recognize the importance of snow guards until the first winter and we were always worried about falling snow on the parking area near our plaza. Thankfully, we did not experience any major problems and decided to install snow guards for the upcoming winter season to avoid such problems in the future. Thanks, Roof Experts!”

Why steel snow guards — not aluminum
We install ORIMA tubular steel snow retention systems rated at 5 kN/m static load (SS 831367). On steel roofs, aluminum clamps cause galvanic corrosion at the contact point over time. Steel-on-steel contact eliminates this risk.
- Rated at 5 kN/m static load — engineered for Ontario snow conditions
- Powder-coated to match existing roof color
- Non-penetrating installation — no holes, no leaks, no warranty issues
- Compatible with all metal roof profiles
Snow guard layout calculation
Each layout is calculated individually based on roof slope, panel length, local ground snow load per NBC 2020, and the location of vulnerable areas below the roof edge — parking, entrances, walkways.
