More roofing & materials terms

• Pipe boot

  The rubber or metal seal around vent pipes that stick through the roof.

• Pipe collar

  The flashing piece that seals a roof where a plumbing vent pipe passes through it, also called a pipe boot. Collars crack with sun exposure, and a failed collar is a leading source of small roof leaks, so it appears as its own line item on a repair scope.

• Ponding water

  Standing water that stays on a roof for more than a day or two after rain because the deck does not drain. In a claim, document the depth, the area, and the drain path with photos and a moisture reading, since carriers argue about whether ponding or a storm caused the damage.

• Power vent

  A roof-mounted exhaust fan that pulls attic air out mechanically instead of relying on passive vents. On a claim it is a separate line item from the shingle tear-off, and carriers often question whether it was damaged or just old, so photograph it before removal.

• Rake

  The sloping outer edge of a gable roof from the ridge down to the eaves. Drip edge is required along rakes as well as eaves, per IRC R905.2.8.5.

• Rake edge

  The sloped edge of a roof where the gable meets the shingles, running from eave to ridge. It takes its own trim, starter, and fasteners, so measure rake length separately from eave length or the material order and the estimate will both come up short.
