Shingles & Materials
Quantity take-off for a re-roof: shingle bundles and squares, underlayment rolls, roofing nails, ridge-cap bundles, drip-edge pieces and metal panels. Coverage typicals are user-adjustable — check your product label. Results are planning estimates.
Working on a roof is dangerous — falls are a leading cause of construction deaths. Measure from the ground, from plans or from photos where possible, use proper fall protection if you must go up, and consider hiring a licensed roofing professional. Results are planning estimates, not a bid.
Shingle BundlesWork out how many bundles of shingles you need from your roof area and a waste allowance. Three bundles cover one 100 sq ft square; the result rounds up.Underlayment RollsFind how many rolls of synthetic or felt (#15 / #30) underlayment your roof needs from its area, a waste allowance and the coverage printed on the roll.Roofing NailsHow many nails per shingle, per square and in total: 4-nail standard or 6-nail high-wind pattern on architectural shingles, with the weight in pounds.Ridge CapA bundle of hip-and-ridge cap covers about 25 to 33 linear feet. Enter your total ridge and hip length and your product coverage to get the bundles to order.Drip EdgeWork out how many pieces of drip edge you need from the total eave and rake length and the piece length, with a 5% allowance for the joint overlaps.Metal PanelsEstimate how many metal roofing panels you need per slope and in total from your eave length, the panel coverage width and the number of slopes.
