Water Pooling on Low-Slope Roof
Hello all. I have a 1000 square foot flat roofed single story house in the Yukon. As you can see from the photos, she collects a good amount of water, probably 2-3” deep before any would flow out the drains. This water freezes in the winter adding weight that reduces my snow load. We are getting much more snow up here near Whitehorse these days, so i would like to slope the roof to shed rain and some snow.
The roof is unvented, made of 16” trussjoists spray foamed, with 2”x4” strapping on both the top and bottom, 5/8” plywood, hot rolled asphalt roofing.
I have a quote on 40’ trusses that would increase to ~2/12 at a cost of ~$7k not including all other materials and time. A gable roof would shed snow onto both entrance porches. There probably are many fixes, if you have opinions, please let me know.
Attached are a few photos.
