They started installing the metal roof yesterday. They were able to complete most of the south facing side. Today they completed the south side (except for the final panel which has yet to be cut), and they completed about a quarter of the north side. Weather willing, they should finish tomorrow.
We’re using a standing seam, snap-on type concealed fastener metal panel system, made by ASP a local sheet metal fabrication company in Scotia. It costs somewhere between a true standing seam (hand folded on site) and a screw down metal roof. The advantage is that the fasteners are concealed so the panels can expand and contract without stressing the fasteners. It’s all prefabricated, so the labor cost is lower.
And now that we can see it in place, we think it looks great.
The south facing side has more fasteners due to the solar panel installation that will be on that side.
We’re still debating snow guards. I have no doubt that snow will accumulate even with a 12/12 pitch and metal roof. When it comes down it will dangerous to anything in it’s way, not to mention our gutters. Had a nice discussion of the merits of a snap on metal roof for solar and snow guards on GreenBuildingAdvisor. Lots of good advice there.
