An interesting project that requires redundant water management detailing

Tape layers should overlap shingle-style up the roof

Snap a line and stick to it

Left-, right-, and straight-cutting snips with single- and compound-leverage each have their place on a jobsite

The first layer of foam is mostly an insulation layer; the outer layer is the air barrier and drainage plane. This video is about the first layer.

Paint-on waterproofing membrane, physics, and forethought protect an old window—and allow future maintenance—while sealing a big hole in a wet and windy wall

If you can't build to stay dry, build to tolerate wet

Putting a window in the hole means sealing around the edges, too

Raised heel trusses and a sealed roof deck make a fast energy efficient roof system

Continuous exterior insulation means smaller studs and higher performance
