Glencoe Carpentry Practice Test

Water intrusion is prevented by metal barriers called flashing, which are installed at joints where roof and wall planes meet and around openings like windows, doors, vents, and chimneys. Flashing creates a waterproof path that directs water away from the interior and into proper drainage, stopping leaks at the most vulnerable seams.

Gutters are meant to collect water runoff from the roof and carry it away from the foundation, not to seal joints. Siding is the exterior surface that protects against weather, but it relies on flashing behind it to prevent leaks at joints. Drip edge is a small metal strip at the roof edge that helps direct water into the gutter, but it isn’t the primary barrier that stops water from seeping through joints. Flirting with the correct concept, flashing is the best term for the sheet metal used to protect the house from water leakage.
