Roof Quantities with the Complete Assembly in View
BidAccurate provides roofing estimating services for roofing contractors and subcontractors, general contractors, material and equipment suppliers, developers, homebuilders, and estimating teams across the United States. We review the bid documents to prepare an organized roofing takeoff or cost estimate for bidding, purchasing, budgeting, and scope review.
The estimate can connect each roof area to its specified covering or membrane, underlayment, vapor retarder, insulation, cover board, attachment method, flashings, drainage, penetrations, accessories, and installation activities. Structural deck repairs, carpentry, masonry, MEP work, hazardous-material handling, and other adjacent scopes are identified separately when responsibility is not part of the agreed roofing package.
Steep-slope coverings by roof plane, pitch, and system
TPO, PVC, EPDM, modified bitumen, BUR, and coatings
Metal panels, insulation, cover boards, and attachment components
Flashings, copings, edges, drainage, curbs, and penetrations
Labor, equipment, tear-off, disposal, and pricing when requested
Excel or PDF reports with color-coded roof plan markups
What's Included in Our Roofing Estimating Services
Every estimate is tailored to the available roof plans, elevations, sections, details, schedules, specifications, addenda, alternates, bid instructions, and contractor responsibility split. The categories below are included only when they belong to the agreed project scope.
Steep-Slope Roofing Systems
Roof plans, elevations, sections, schedules, details, and specifications are coordinated so each roof plane, pitch, covering, and accessory remains identifiable.
Asphalt and composite shingles, clay or concrete tile, slate, wood shakes, and wood shingles
Underlayment, self-adhered membranes, starter courses, hip and ridge caps, and ventilation products
Roof area adjusted for documented slope, product coverage, laps, cuts, and agreed waste assumptions
Low-Slope and Commercial Roof Systems
Field membrane and assembly layers are separated by system, attachment method, thickness, roof area, and detail so the estimate reflects more than the roof surface alone.
TPO, PVC, EPDM, modified bitumen, built-up roofing, liquid-applied, and coating systems
Mechanically attached, adhered, induction-welded, ballasted, hot-applied, and cold-applied assemblies as specified
Base sheets, ply sheets, cap sheets, membranes, surfacing, adhesives, primers, fasteners, and plates
Field, perimeter, corner, transition, tie-in, expansion-joint, and phased-roof conditions
Metal Roofing and Sheet-Metal Work
Panels and related sheet-metal items are classified by profile, material, finish, width, length, location, and connection detail when they belong to the roofing package.
Standing-seam, exposed-fastener, corrugated, metal shingle, and insulated metal roof panels
Clips, fasteners, sealants, closures, underlayments, separation layers, and thermal spacers
Ridge, hip, valley, rake, eave, transition, apron, step, counter-, and penetration flashings
Coping, fascia, gravel stop, edge metal, gutters, downspouts, collector heads, and scuppers when scoped
Insulation, Boards, and Drainage
Below-membrane layers and drainage components are tied to the roof assembly, elevations, taper plan, and details to keep thicknesses and discrete items reviewable.
Flat and tapered polyisocyanurate, EPS, mineral wool, composite insulation, and saddles or crickets
Cover boards, protection boards, vapor retarders, air barriers, separation sheets, and slip sheets
Primary and overflow drains, sumps, scuppers, gutters, downspouts, splash blocks, and drainage accessories
Roof hatches, curbs, sleepers, pipe boots, pitch pockets, vents, skylights, walk pads, and penetrations
Labor, Equipment, and Scope Boundaries
When pricing is requested, measurable installation and removal activities are paired with confirmed inputs while adjacent-trade responsibilities and allowances remain explicit.
Crew production, wage rates, equipment rates, freight, taxes, overhead, profit, and escalation when agreed
Deck repair, structural framing, carpentry, masonry, HVAC, plumbing, electrical, hazardous materials, and testing separated as required
Measurement and Reporting
Each quantity uses a purchasing- and installation-relevant unit, with reports organized for bid review, supplier quotations, procurement, or internal estimating.
Roofing squares (SQ) or square feet (SF) for coverings, membranes, insulation, boards, and underlayments
Linear feet (LF) for perimeters, seams, hips, ridges, valleys, curbs, flashings, copings, gutters, and joints
Each (EA) for drains, scuppers, penetrations, hatches, vents, curbs, skylights, and accessories
Rolls, sheets, boards, bundles, gallons, pounds, labor hours, equipment days, or assemblies as applicable
Need a Roofing Number Before Bid Day?
Share the current plans, specifications, addenda, project location, bid deadline, supplier quotes, labor rates, and preferred cost breakdown. We will review the documents and confirm the takeoff, estimate, and delivery structure.
Roof plans, elevations, sections, details, schedules, specifications, and addenda are coordinated so coverings, assembly layers, flashings, drainage, and accessories remain connected.
Faster Bid Preparation
Organized roof areas, edge lengths, detail quantities, labor activities, and marked drawings reduce manual measurement time before supplier outreach and final pricing.
Purchasing Clarity
Breakdowns by system, membrane or covering, thickness, attachment method, roof area, elevation, and accessory help contractors and suppliers prepare comparable quotations.
Reduced Scope Omissions
Checks for insulation layers, cover boards, perimeter zones, flashings, penetrations, drainage, curbs, walk pads, tear-off, access, and disposal help surface commonly missed bid items.
Reviewable Deliverables
Color-coded plan markups, drawing-referenced worksheets, roof-area breakdowns, inclusions, exclusions, allowances, and assumptions make the estimate easier to audit and revise.
Flexible Pricing Inputs
Your supplier quotes, labor rates, production assumptions, equipment costs, waste factors, cost codes, and estimate template can be incorporated when supplied.
Roofing bids depend on coordinated system layers, roof geometry, detail-specific quantities, realistic installation activities, and clear boundaries among roofing, sheet metal, carpentry, structural, plumbing, and mechanical scopes. Our workflow keeps those decisions visible.
01
Roofing-Specific Document Review
We coordinate roof plans, elevations, sections, details, schedules, specifications, addenda, and relevant architectural, structural, plumbing, and mechanical information.
02

Coverings or membranes, underlayments, vapor retarders, insulation, cover boards, attachment components, flashings, drainage, and accessories can be grouped by roof system and area.
03
Geometry and Conditions Are Separated
Documented slopes, roof planes, elevations, perimeters, corners, penetrations, curbs, transitions, phasing, and access conditions are carried into the quantity and labor structure.
04
Scope You Can Audit
Marked drawings, source references, alternates, allowances, exclusions, adjacent-trade boundaries, and unresolved document conditions provide context behind the quantities.
05
Contractor-Ready Formats
Excel and PDF outputs can follow building, roof area, elevation, system, assembly, material, bid item, cost code, supplier list, or your existing estimating structure.
06
Addenda and Revision Support
When revised documents are submitted, affected roof areas, assemblies, quantities, labor, pricing, alternates, and scope notes can be compared and updated under an agreed revision scope.
Our Roofing Takeoff and Estimating Process
A defined workflow moves the project from document intake and scope confirmation through roof-system measurement, pricing, coordination, review, and contractor-ready delivery.
1
Submit the Roofing Documents
Send roof and architectural plans, elevations, sections, details, schedules, specifications, addenda, bid form, project location, bid deadline, and available supplier or labor pricing.
2
Confirm the Roofing Scope
We align on roof systems, tear-off or new work, insulation, flashings, sheet metal, drainage, accessories, alternates, exclusions, pricing needs, waste basis, and reporting format.
3
Measure Roof Areas and Details
Roof planes, documented slopes, membranes or coverings, assembly layers, perimeters, hips, ridges, valleys, penetrations, curbs, drainage, and accessories are quantified by system and location.
4
Develop Labor and Costs
When estimating is requested, confirmed material pricing, crew production and rates, equipment, access, freight, tear-off, disposal, waste, and agreed indirect costs are applied to the takeoff.
5
Coordinate and Review
The takeoff is checked across plans, elevations, sections, details, schedules, specifications, and addenda while conflicts, gaps, alternates, exclusions, and assumptions are recorded.

Deliverables Built for Bidding and Purchasing
Use the package to request roof-system, insulation, sheet-metal, and accessory quotations; develop labor pricing; compare subcontractor coverage; reconcile addenda; plan purchasing; or transfer quantities into your estimating system. Deliverables support bid decisions and do not replace design, engineering, manufacturer requirements, code review, field verification, or contractor means and methods.
Roofing Material Takeoff
Roof coverings or membranes, assembly layers, insulation, boards, fasteners, flashings, sheet metal, drainage, and accessories grouped by the agreed system and location structure.
Labor and Cost Estimate
Material, crew labor, equipment, access, tear-off, disposal, freight, waste, supplier quotes, and requested indirect costs extended from the confirmed project and pricing basis.
Color-Coded Roof Markups
Marked plans showing measured roof areas, slopes, perimeters, hips, ridges, valleys, penetrations, curbs, drains, flashings, and other scoped elements for quantity verification.
Scope and Assumption Log
Drawing references, inclusions, exclusions, trade boundaries, alternates, allowances, attachment and waste assumptions, and unresolved document conditions collected for review.
Related Construction Services
Pair roofing estimating with broader quantity takeoffs, full construction cost estimating, or a separately defined carpentry package using existing BidAccurate services.
Send the available roof and architectural plans, elevations, sections, roof schedules, details, specifications, addenda, bid form, project location, and bid deadline. Existing-condition reports, roof photos, supplier quotes, labor rates, production assumptions, waste factors, cost codes, and your preferred estimate template are also useful when they affect the requested scope.
What is included in a roofing takeoff?
The agreed scope can include steep-slope coverings, low-slope membranes, metal panels, underlayments, vapor retarders, insulation, cover boards, adhesives, fasteners, flashings, copings, edge metal, gutters, drainage, curbs, penetrations, accessories, tear-off, installation activities, and marked-up drawings. Actual inclusions depend on the documents and contractor responsibility split.
Is a roofing takeoff the same as a roofing estimate?
No. A roofing takeoff measures and lists material, assembly, accessory, and work quantities shown in the bid documents. A roofing estimate extends those quantities with material prices, crew production, labor rates, access equipment, tear-off, disposal, freight, supplier quotes, and any agreed indirect costs, taxes, overhead, profit, or allowances.
How are roofing quantities measured and reported?
Roof coverings, membranes, insulation, boards, and underlayments are commonly reported in roofing squares or square feet; perimeters, seams, hips, ridges, valleys, flashings, copings, gutters, and joints in linear feet; and drains, scuppers, curbs, penetrations, hatches, vents, and accessories as each. Reports can also include rolls, sheets, boards, bundles, gallons, pounds, labor hours, or equipment days and can be grouped by building, roof area, system, elevation, or bid item.
Which roofing estimate file formats will I receive?
Typical deliverables include Excel quantity or cost workbooks, PDF reports, and color-coded PDF roof plan markups. We can discuss organizing the package by building, roof area, elevation, system, assembly, material, alternate, bid item, cost code, supplier list, or your own spreadsheet structure before work begins.
Can you revise a roofing estimate after an addendum?
Yes. Submit the revised plans, schedules, details, specifications, addendum, and revision instructions. We can compare the affected roof areas, assemblies, quantities, labor, pricing, alternates, and scope notes and update the agreed takeoff or estimate; the effort and delivery date depend on the extent and clarity of the changes.
Can you use our supplier pricing and roofing labor rates?
Yes. BidAccurate can use client-provided roofing, insulation, sheet-metal, accessory, freight, disposal, and equipment quotations along with crew rates, production assumptions, waste factors, taxes, and markups when those inputs are supplied and included in the agreed scope. The pricing and assumption basis can be identified for review.
What affects roofing estimating turnaround time?
Turnaround depends on project size, roof geometry, system and assembly complexity, the number of details and penetrations, reroof investigation, document completeness, required material and location breakdowns, requested pricing detail, alternates, addenda, bid deadline, and current workload. We review the documents first and confirm a delivery date for the requested package.
