Commonly-usedroofing terms.

The words that turn up on a roofing scope, each one explained the way a crew lead would explain it on the ladder.

Decking
The plywood or OSB sheathing over the rafters. Everything above it is fastened into this, so soft sheets get swapped out at tear-off.
Underlayment
The layer between decking and shingles. Synthetic across the field, self-adhered ice-and-water shield at the eaves and valleys where water sits.
Flashing
Bent metal sealing the joints at chimneys, walls and skylights. Against a sidewall it goes in one piece per course — step flashing — never as one long strip.
Drip edge
Metal at the roof edges that throws runoff clear of the fascia. Under the underlayment at the eave, over it at the rake.
Valley
The crease where two slopes meet. It carries more water than anything else on the roof, so it gets ice-and-water shield before a shingle touches it.
Pipe boot
The rubber collar around a plumbing vent. The rubber cracks years before the shingles wear out, which makes it the usual cause of a small ceiling stain.
Ridge vent
A low vent cut into the peak that exhausts hot attic air along its whole length. A few feet of it moves what a turbine does, with nothing to seize.
Soffit
The underside of the overhang. Vented soffit is the intake half of attic ventilation — without it a ridge vent pulls its air out of the house.
Fascia
The board along the roof edge that carries the gutter. First thing to rot when the drip edge was set wrong.
