This bench is north of the Trans-Canada, so the design ground snow pressure stays 1.8 kPa. Do not let a replacement proposal import the Mount Dufferin number to sound thorough. Do let it take wind seriously. Gusts at the Kamloops station hit 98 km/h in the 1991 to 2020 normals, and this slope is more exposed than a treed Westsyde lot. Edge metal, starter courses, and fastener schedules are the conversation. A pretty shingle that peels at the rake is a failed replacement.
Grassland fuel, not a cedar hedge
Lac du Bois grasslands put fine, cured fuel beside the eave. FireSmart's rejection of wood shakes is the local point. Class A asphalt or another rated covering fits. Metal fits if it is fastened for uplift and if any snow that does slide, even under the lower design load, misses the door. That detail is on Batchelor metal. Gutters should be metal. A vinyl gutter on a new roof facing the protected area is a step backward.
Edges fail here before the field does
On this bench the rake and the starter course see the wind before the middle of the slope looks tired. A replacement that is beautiful in the field and loose at the edge will peel on the next strong gust. Ask for the edge metal and the fastening at the perimeter to be written down, not waved at. Also say whether a trailer can turn around in the driveway. Winter bookings on this hill fail when that detail is left out.
Small wind repairs that are not a full replacement remain on Batchelor repair.
Call (236) 836-0303 and say whether shakes are still up. No dollar range will be read back to you from a script.
