Flashing under an exterior door and along the bottom of a basement wall that used to have an overhead door

A drip edge overlapping strategy that won't catch the eye

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

Roofs peel off from the edges, so it is critical to hold them tight

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.

A retrofit solution that works great for a low-skill workforce—like volunteers

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

Make a route for drainage, protect the structure, and use water-tolerant materials to rebuild

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