Roofing & Materials
Scupper
An opening through a parapet wall that lets water drain off a flat or low-slope roof. It is usually a line item on the estimate, and keeping it clear of debris is part of the repair. Blocked scuppers are a common cause of ponding and interior leaks.
More roofing & materials terms
- Roofing sealant
A flexible caulk or sealant applied at flashings, penetrations, and edges to keep water out. Estimates generally show it as its own line item rather than bundling it into shingle or flashing labor. Workmanship warranties cover how it is applied, not the product alone.
- Roofing square
One hundred square feet of roof surface, the unit roofers use for ordering material and pricing labor. A square usually takes three bundles of shingles, though that varies by product. Measure in squares first, then convert to bundles.
- Sheathing
Another name for roof decking, the structural surface under the roof covering.
- Siding damage
Dents, cracks, or holes in wall cladding from hail, wind, or impact. Siding is handled separately from roofing on a claim, with its own line items and its own repair-versus-replace rules that vary by material. Partial elevation replacement can leave a color or texture mismatch.
- Skylight
A window set into the roof; the flashing around it is a common missed line item.
- Slope
How steep a roof is, expressed as rise over run, a 6/12 roof rises 6 inches for every foot it runs.
