Wind uplift is the specification that changes here. A mechanically seamed panel with a 180° double lock is a fundamentally different structure to a snap-lock panel under uplift — the seam is folded closed rather than clipped, so it resists peeling at the ridge and rakes where uplift concentrates. On exposed shoreline properties around Southampton, Port Elgin and the Sauble shore, that is the detail worth paying for.
We cover Owen Sound, Meaford, Thornbury, Southampton, Port Elgin, Wiarton, Kincardine, Hanover, Durham, Chesley and the Bruce Peninsula up toward Lion's Head and Tobermory.
