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.
