The shear
When a metal roof releases, tonnes of consolidated snow slide as one sheet. A plumbing stack or flue in its path bends flat or snaps off — often invisibly, under the snow.

A VentSaver is a snow diverter that mounts on the roof above a vent pipe, flue or chimney pipe and splits sliding snow around it — so the moving snowfield can't bend, shear or rip the penetration out of your metal roof. Two models, EZ and HD, ship from Paris, Ontario in Canadian dollars.
Why vents fail in winter
When a metal roof releases, tonnes of consolidated snow slide as one sheet. A plumbing stack or flue in its path bends flat or snaps off — often invisibly, under the snow.
Even without a slide, the snowpack creeps downslope all winter — bending pipes a few millimetres at a time until flashings tear and the boot leaks.
A sheared vent isn't a pipe problem — it's a roof leak, an attic moisture problem, and for gas appliance flues, a venting hazard. The diverter costs less than the service call.
The standard guard for residential vent pipes. Choose no plate (mount to your own retention), a standing seam mounting plate, or the plate-and-wing kit for wider protection.
The heavy-duty wedge for larger flues, chimney pipes and high snow-load roofs. Available with no plate, a standing seam plate, or a screw-down plate.

VentSavers split sliding snow around a single penetration. To stop the slide itself — over doors, decks and gas meters — pair it with SnoBar® rails or pad-style snow guards. Most roofs need both, and one warrantied layout covers it all.
