CSI Division 07 Roofing estimating inquiry
Agree quantities by roof zone and assembly, net versus waste areas, accessory lengths and detail counts. Manufacturer coverage and fastening requirements must follow the specified system.
Specialized construction takeoffs
Review materials, units and scope
Confirm your deadline before work starts
Plan-based quantity takeoffs
Identify the current drawing revision, included systems, alternates and addenda. Agree whether labor, equipment, demolition, testing, permits, taxes, freight and owner-furnished items are included. Missing design information needs a recorded allowance or clarification; estimating does not replace engineering design or code approval.
Keep measured quantities separate from waste and procurement allowances. For a priced estimate, confirm the project location, pricing date, supplier inputs and labor basis. Final bid qualifications and markups remain subject to contractor review.
Roofing systems demand extreme precision in calculating roof slope pitch multipliers, tapered insulation slope layouts, parapet wall flashing heights, and penetrations (pipe boots, pitch pans, skylights). An error in wind uplift fastening patterns or polyiso thickness can cause major bid discrepancies.
Roof slope pitches, wind uplift ratings, parapet wall details
Flat vs sloped square footage (Squares = 100 SF)
TPO, EPDM, PVC, shingles, ice & water shield
Polyiso R-values, slope crickets & cover boards
Parapet copings, drip edges, gutter & downspouts
Penetration boots, warranty specs & bid package
Every estimate prepared by F&K Estimatings delivers an exhaustive line-item breakdown formatted for material suppliers, specialty subcontractors, and general contractor bid reviews.

Squares (SQ), roll counts (10x100, 12x100), adhesive gallonage, and fastener box counts.
Every roofing estimate follows CSI MasterFormat Division 07 standards and complies with NRCA (National Roofing Contractors Association) guidelines.
Our takeoff schedules separate low-slope, steep-slope, insulation, and sheet metal into distinct packages.
Heat-welded single-ply reflective roof membranes and accessories.
Ethylene propylene diene monomer rubber roof systems.
Polyisocyanurate flat, tapered, and cover board insulation.
Architectural, laminated, and designer steep-slope shingles.
Standing seam, architectural metal, and concealed clip panels.
Parapet coping caps, gravel stops, gutters, and downspouts.
Roofing estimating requires calculating exact pitch multipliers (e.g., 6:12 slope = 1.118 multiplier; 12:12 slope = 1.414 multiplier) and modeling tapered polyiso crickets to ensure positive drainage toward internal roof drains.
Send your drawing sheets for a dedicated takeoff schedule.
Reference multipliers applied by our roofing estimators:
Understanding whether your team needs raw quantity measurements or a fully priced bid estimate helps you order the exact service you require.
Our systematic 7-step engineering process eliminates missing elements, prevents duplicate counts, and delivers defensible estimates.
We review roof plans, wall sections, parapet details, drain schedules, wind uplift requirements, and Division 07 specs.
Using digital takeoff software, we measure planar roof areas and apply geometric slope multipliers to establish true area.
We calculate flat polyiso base layers, tapered slope panels, drain sumps, and cover boards.
We calculate TPO/EPDM membrane rolls, side/end lap allowances, starter strips, and underlayments.
We measure parapet coping caps, drip edge, gutters, downspouts, scuppers, and pipe penetration boots.
We calculate tear-off and install labor hours, safety tie-offs, rooftop telehandler/crane logistics, and dumpsters.
A Senior Estimator conducts a peer review to verify manufacturer warranty specs, edge metal certifications, and addenda.
From commercial tenant fit-outs to heavy industrial complexes, we adapt our takeoff methodology to project specifications.
Warehouses, strip malls, office buildings with fully adhered or mechanically attached TPO/EPDM/PVC membranes.
Architectural shingles, steep slope valleys, synthetic underlayments, ridge vents, and seamless gutters.
Large-acreage single-ply roof membranes, high wind-uplift induction welding, and skylight curbs.
Combination roofs with steep-slope shingle mansards and flat single-ply membrane top decks.
Churches, municipal centers, schools, and high-end residential metal roofing with concealed clips.
Tear-off down to structural deck, wet insulation replacement, deck repair, and overlay systems.
Material and labor costs fluctuate drastically by project geography, supplier logistics, trade union jurisdictions, and site conditions. We do not use flat national averages.
Confirm the pricing date, project ZIP code, supplier quotations, labor basis and equipment allowances in the project brief. Identify any owner-supplied rates or provisional costs separately.
Steep pitches (8:12 and above) require roof brackets, scaffolding, and harness tie-offs, reducing daily crew productivity.
High wind zone specifications require 50% more fasteners and plates per board in corner and perimeter roof zones.
Tearing off multiple existing asphalt/gravel roof layers doubles labor hours and requires hazardous dumpster disposal.
Factory Kynar 500 pre-finished metal copings carry a premium over standard mill finish aluminum.
20-year and 30-year No Dollar Limit (NDL) manufacturer warranties mandate certified inspections and specific component assemblies.
Review illustrative project models demonstrating how CSI Division 07 Roofing quantities are extracted, itemized, and structured under standard contractor bidding conditions.
Agree the scope and review requirements for your project. Check quantities against the supplied drawing revision and record unresolved items before preparing a final bid.
When bidding tight commercial deadlines, subcontractors cannot afford incomplete takeoffs or guesswork. A clear estimating brief helps identify the quantities, pricing inputs and qualifications needed for bid review.
Request drawing references and identify allowances separately from measured quantities.
Identify addenda and agree the revision scope, fee and delivery date.
Confirm the spreadsheet format, formulas and cost inputs required for your bid.
Confirm the project ZIP code, pricing date, supplier quotations and labor basis.
Detailed technical and commercial answers to help you navigate roofing estimating service, material scheduling, and bid preparation.
For a contractor bid, identify the trade package, issued plan revision, specifications, alternates and the responsibility for adjoining work. Separate measured quantities from unit prices, subcontractor quotations and project allowances so the bid reviewer can trace each assumption.
Agree the spreadsheet columns, drawing references, exclusions, pricing date and revision allowance before work starts. An addendum or changed scope needs an identified issue date and change record; an illustrative sample does not establish project-specific pricing or specialist experience.
Compare commercial bid estimating scope with the published sample evidence, then request the required handoff.
