Precision Roofing Estimating & Takeoff Services
Comprehensive material takeoffs for commercial and residential roofing contractors. We quantify single-ply TPO/PVC/EPDM membranes, architectural shingles, standing seam metal, tapered insulation board-feet, crickets, and ES-1 certified parapet copings.
Roofing: quantities, checks and quote requirements
Roofing takeoffs measure roof area in squares with slope factors, insulation and coverboard, flashing and sheet metal by length, and drains, curbs and penetrations by count.
Measurement and reporting basis
- Membrane, shingle or metal roofing (SQ)
- Insulation and coverboard, including tapered systems (SF)
- Edge metal, coping and flashing (LF)
- Drains, scuppers and penetrations (EA)
- Fastening and attachment
Documents to include
- Roof plan and details
- Roofing specification and wind-uplift requirements
- Energy code insulation requirements
Also identify the current revision, addenda, project ZIP code, requested trades and bid deadline.
A scope check before pricing
Separate plan area from sloped roof area and squares (one square is 100 SF). Count perimeter edges, penetrations, flashings, tapered insulation and tear-off layers independently.
Scope limits: Roof inspection, wind-uplift design, warranty acceptance and concealed deck condition require separate review.
The written quote defines the deliverables and revision coverage. Measured quantities and drawing markups can be supplied for the agreed scope; a priced estimate adds the identified material, labor and equipment cost basis. Missing information is recorded as a clarification or allowance.
Send the documents above for a written quote confirming the scope, fee and delivery date after document review. Indicate whether you need quantities only, a priced estimate or a review of an existing bid.
Request a roofing scope quoteWhat Are Roofing Estimating Services?
Roofing estimating services provide itemized digital quantification of all roofing membranes, shingles, underlayments, insulation boards, sheet metal flashings, and rooftop accessories required to construct a watertight building envelope. An expert takeoff models measured pitch multipliers, tapered insulation slope fill, lap seam scrap, and ANSI/SPRI ES-1 parapet coping stretchouts—with assumptions stated for bid review.
Complete CSI Division 07 Roofing Scope
Our senior roofing estimators quantify all commercial flat roof and residential steep-slope assemblies:
Thermoplastic Membrane Roofing (TPO / PVC)
Mechanically fastened, induction-welded, and fully adhered TPO & PVC single-ply membranes with heat-welded seams.
Elastomeric Membrane Roofing (EPDM)
Ballasted, mechanically attached, and fully adhered EPDM rubber roofing systems with seam tapes and primers.
Roof & Deck Insulation
Polyisocyanurate (Polyiso) flat & tapered board layouts, EPS/XPS fill, and high-density cover boards (DensDeck, HD ISO).
Shingles & Shakes
Architectural laminated asphalt shingles, synthetic composite slate, cedar shakes, ridge caps, and underlayments.
Roof Panels (Standing Seam Metal)
Architectural and structural standing seam metal panels (snap-lock and mechanical seam), clips, and eave closures.
Sheet Metal Flashing & Trim
Parapet wall coping caps (ES-1 certified), counterflashings, drip edges, gravel stops, commercial gutters, and scuppers.
Roof Accessories
Roof hatches, smoke vents, skylights, equipment curbs, pipe penetration flashings, and safety tie-off anchors.

Our 4-Step Forensic Roofing Methodology
How we eliminate bidding blind spots and protect your profit margins on bid day:
Roof Plan & Slope Audit
We analyze roof plans, deck types, slope pitch ratios, drain locations, overflow scuppers, and parapet wall heights.
Digital QTO Measure
Using PlanSwift & Bluebeam, we calculate true pitch-adjusted square footages, linear flashings, and count all penetrations.
Tapered 3D Modeling
We model tapered polyiso slopes, cricket board-feet, drain sumps, membrane side laps, and 8-12% waste factors.
Pricing & QA Review
We apply documented labor assumptions and manufacturer material quotes. A senior estimator audits the entire package.
Frequently Asked Questions About Roofing Estimating
What is included in your commercial and residential roofing takeoff services?
Our roofing estimating deliverables include measured square footage (roof squares) for single-ply membranes (TPO 60/80-mil, PVC, EPDM), asphalt architectural shingles, standing seam metal panels, modified bitumen, and built-up roofing (BUR). We also quantify polyiso base & tapered insulation board-feet, cover boards (DensDeck, HD ISO), parapet coping caps per ANSI/SPRI ES-1, counterflashings, drip edges, gutter/downspout linear footages, roof drains, and penetration boots.
How do you calculate tapered insulation slopes, crickets, and average R-values?
We design and model 3D tapered roof insulation layouts—calculating measured slope fill panel board-feet (1/8", 1/4", 1/2" per foot), drainage sump depressions, and saddle crickets between scuppers and internal roof drains to ensure zero ponding water and verify code-mandated continuous R-30 / R-38 thermal values.
Do you quantify parapet wall copings, edge metal, and sheet metal stretchouts?
Yes. We quantify all architectural sheet metal per SMACNA & ANSI/SPRI ES-1 guidelines: calculating 24ga Kynar-500 parapet coping stretchouts (top width + face/back drops), continuous cleats, splice plates, counterflashings, gravel stops, commercial gutters, and downspout conductors.
How do you handle rooftop penetrations, curbs, and pipe flashings?
We count every rooftop penetration itemizing prefabricated RTU equipment curbs, exhaust fan curbs, pipe boots, pitch pockets, fall-protection tie-off anchor posts, and roof access hatches with manufacturer-approved 20-year NDL (No Dollar Limit) detail specifications.
What is your standard turnaround time for a commercial roofing takeoff?
Delivery depends on the drawing set, requested trade scope, pricing requirements and bid deadline. The delivery date, scope and revision coverage are confirmed in the written quote after document review.
What software platforms do you use for roofing takeoffs?
We use specialized roofing estimating software including The Edge (Estimating Edge), PlanSwift, Roofr, RoofScope, and Bluebeam Revu, delivering fully editable, formula-driven Excel spreadsheets structured by CSI Division 07.
How do you price roofing labor, tear-off, and installation costs?
We apply documented client or supplier pricing inputs or your crew piece-rate square costs, calculating production labor hours for tear-off (single vs multi-layer), substrate prep, insulation fastening, induction welding, and sheet metal fabrication.
Can general contractors use your roofing takeoffs for warranty and bid leveling?
Yes. General contractors use our independent takeoffs to verify roofing sub-tier proposals, confirm insulation R-value compliance, verify fastener pull-out patterns for high-wind zones, and prevent change-order disputes.
