Mechanical lock and snap lock standing seam systems manufactured on-site. Increasingly specified on premium Ontario builds — and we're the only local contractor with a portable roll-former.
Metal roofing demand in Ontario has grown significantly as builders and buyers recognize the long-term economics: one installation that lasts 40-70 years versus asphalt that requires replacement every 20-30 years. For custom home builders and architectural builds, standing seam metal is increasingly the specified standard.
519 Roofing operates the only portable job-site roll-forming machine in Southwestern Ontario. Metal panels are cut to exact length on your property — eliminating distributor delays, reducing waste, and delivering a precision fit that off-site panels cannot match. For builders, this means faster installs and no material handling surcharges.
| System | Lifespan | Maintenance | Warranty |
|---|---|---|---|
| Architectural Asphalt | 20-30 yrs | Low | OC Registered |
| Snap Lock Metal | 40-60 yrs | Very Low | Manufacturer |
| Mechanical Lock Metal | 50-70 yrs | Minimal | Manufacturer |
