Division 07 · Roofing
A roof bid built from the footprint and a guessed waste factor is a roof bid that loses money on hips, valleys and dormers. Our roofing estimators take every plane off the roof plan, apply the pitch factor to convert flat area to true area, and count the linear feet of ridge, hip, valley, eave and rake that drive flashing, starter and accessory quantities. Steep-slope shingle, metal, tile and slate, low-slope TPO, EPDM and modified bitumen, new construction or tear-off, each priced for the project zip code.

Overview
Roofing is quantified in squares, and one square is 100 square feet of finished roof surface. The estimator starts with the roof plan, breaks the roof into planes, measures the flat area of each plane and multiplies by the pitch factor for its slope: a 6:12 roof carries a factor of 1.118, a 12:12 roof a factor of 1.414. The sum of the true areas, divided by 100, is the base square count. From the same plan we pull linear feet of eave, rake, ridge, hip and valley, because those lines govern drip edge, starter strip, ridge cap, hip cap and valley metal far more than the field area does.
Waste is where roofing estimates diverge. A simple gable with two planes wastes around 10 percent of shingles to cuts and starter; a cut-up hip roof with multiple valleys and dormers can run 15 to 20 percent, and architectural shingles waste differently than three-tab because of their exposure. We assign waste by roof complexity rather than a single blanket number, and we carry it separately for field shingles, underlayment, ice and water shield and metal so each material is ordered in the bundles, rolls and sheets it actually ships in. Fasteners, pipe boots, step flashing and vents are counted, not percentaged.
Low-slope work follows a different logic. Membrane roofs are measured in squares too, but the cost lives in the insulation stack, cover board, tapered crickets, drains, scuppers, curbs and the perimeter and corner zones where uplift pressures demand tighter fastening or full adhesion. Whether the project is a new build, a full tear-off, a change in roof form, a commercial re-cover or a leak repair, this hub page and its five linked pages explain what we measure, how labor is built by crew-day and pitch, and what the delivered workbook looks like for each type of roofing scope.

Process
Four steps from upload to a bid-ready estimate, with a senior estimator signing off before anything leaves our desk.
Send your drawings, specifications and bid invitation through the secure upload form. We confirm scope, deadline and a fixed price within two business hours.
Estimators measure every item from calibrated plans in Bluebeam and PlanSwift, color-coding each layer so quantities can be traced back to the drawing.
Quantities are priced with location-adjusted material costs, crew productivity rates and equipment, then marked up to your overhead and profit targets.
A second estimator audits quantities and pricing, documents assumptions and exclusions, and delivers your Excel workbook, PDF summary and marked-up plans.
Why LEEDS
An estimating desk that behaves like an extension of your team, not a software subscription.
Every roof plane is measured and pitch-factored individually, so cut-up hip roofs are not priced like simple gables.
Waste factors assigned by roof complexity and shingle type, carried separately for field, underlayment, membrane and metal.
Eave, rake, ridge, hip and valley lengths, pulled from the plan to drive flashing, starter and cap quantities exactly.
Ventilation sized to net free area from the, attic footprint rather than guessed from a count of existing vents.
Low-slope insulation, cover board, tapered, crickets and uplift zones quantified by layer the way the manufacturer's warranty requires.
Material priced per bundle, roll, sheet and box from current distributor quotes for the project zip code.
Labor built per square by system, pitch and roof height, with tear-off, staging and safety setup itemized separately.
Five linked pages cover new roofing, replacement, remodeling, renovation and repair so you get the right scope logic every time.
Every deliverable is formatted so it can go straight into a proposal, a purchase order or an owner report.

Reviews
What general contractors, subcontractors and developers say after bidding with our numbers.
“Squares, underlayment, flashing lengths, fastener counts, even the ridge vent. The waste factors were right for the roof pitch. Bid-ready out of the box.”

Estimator, Summit Roofing Co. · Kansas City, MO
“We were turning down bids because our two in-house estimators were buried. LEEDS gave us division-by-division numbers in 48 hours that leveled cleanly against our sub quotes. We bid 40% more work last quarter and our hit rate went up, not down.”
Marcus Whitfield
Chief Estimator, Whitfield Commercial Builders · Charlotte, NC
“Lumber lists, finish schedules and allowances in a format our clients actually understand. The assumptions log alone has saved us from two scope disputes.”

FAQ

We measure the flat area of each roof plane from the calibrated plan, multiply it by the pitch factor for that plane's slope, then sum the true areas and divide by 100 to get squares. Pitch factors come from the slope shown on the elevations or sections, and when a plane's pitch is not labeled we derive it from ridge height and span and note the assumption.
It depends on the roof. Simple gables carry roughly 10 percent, hip roofs 12 to 15 percent, and roofs with multiple valleys, dormers and turrets 15 to 20 percent. Architectural shingles, three-tab, metal panels and tile each waste differently, so we assign waste per material and per roof complexity and show the factor in the workbook where you can adjust it.
Yes. Steep-slope shingle, metal, tile and slate roofs are measured by plane and pitch with flashing and accessories by linear foot. Low-slope TPO, EPDM, PVC, modified bitumen and built-up roofs are measured by area with insulation by layer, cover board, tapered crickets, drains, curbs and perimeter fastening zones itemized according to the manufacturer's assembly and the uplift requirements on the drawings.
New roofing covers ground-up construction where the deck is new. Roof replacement covers full tear-off and re-roof on an existing building. Roofing remodeling covers changing the roof form or material, such as adding dormers or switching shingle to metal. Roofing renovation covers commercial re-covers and restoration coatings, and roof repair covers leaks, flashing, storm damage and partial replacement. If the scope mixes types, send it here and we will split it.
Yes. For existing roofs without drawings we work from aerial measurement reports, satellite imagery or your field sketch with pitch readings, and we reconcile the plane areas against the building footprint before applying waste. The workbook flags any plane where the pitch or edge type was assumed so your crew can verify it on the ladder inspection.
Single-family and small commercial roofs are usually delivered within 24 hours. Multifamily complexes, cut-up institutional roofs and large low-slope buildings with tapered insulation take 48 hours. Multi-building portfolios are scheduled individually and we confirm the delivery date before we start measuring. Rush delivery for bid-day deadlines is available on request.
