Pipe collar

More roofing & materials terms

• Peel-and-stick membrane

  A self-adhering roofing membrane, often used as underlayment on steep-slope roofs or as a cap sheet on low-slope roofs, that seals around nails and resists ice dams. It is priced by the square, and where it is required depends on the local code.

• Pipe boot

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

• Plywood

  The wood sheathing panels nailed to roof framing, sold in thicknesses like 7/16 or 15/32 inch and rated for roof decking. Decks are replaced when they are delaminated, rotted, or too thin for the new covering, and the replacement is priced by the sheet.

• 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.
