If you’ve ever painted dormers or half gables on the outside of a house you know that resting a paint can while working on a rooftop can really be tricky. Our solution: create a triangular platform with an angle opposite the roof (a bevel gauge and level will show you what the level needs to be). We made ours of half-inch plywood with a lip around the top. To give the platform traction on the steep roof we attached two strips of self-adhesive weatherstrip to the underside.
