Jobplans is browser-based roofing takeoff software that measures every roof scope on your drawings and calculates squares, membrane, insulation, fasteners, flashing, and labor from the same measurements — in a single dynamic table. 9+ roofing and waterproofing templates covering TPO, EPDM, BUR, modified bitumen, metal standing seam, and shingle systems. Runs on Mac, Windows, iPad, iPhone, Android, Chromebook, and Linux. Measure the roof area, apply pitch adjustment, and watch the square count, insulation boards, fasteners, flashing runs, penetrations, and labor hours populate automatically. Change the pitch or membrane type and every downstream quantity recalculates. Export to CSV (Excel-compatible) or share a live link with your PM, foreman, or material supplier. ## Why roofing takeoffs are error-prone Roofing estimates look simple — "how many squares?" — but they are surprisingly fragile because a roof has many layers and each layer has its own waste factor, fastening pattern, labor rate, and material dependency. A single commercial reroof project involves: - **Membrane** — TPO, EPDM, PVC, BUR, modified bitumen, metal, or shingle - **Insulation** — polyiso, XPS, EPS, tapered insulation for slope, with R-value targets - **Cover board** — gypsum, HD polyiso, or plywood for impact resistance - **Vapor barrier** — for cold climates and controlled environments - **Fasteners and plates** — pattern varies by wind zone and attachment method - **Adhesive** — for fully adhered systems - **Flashing** — base, counter, cap, edge metal, coping, termination - **Penetration flashings** — vent pipes, drains, scuppers, conduit, equipment curbs - **Edge metal and drip edge** — linear feet of perimeter - **Walk pads** — protected pathways around equipment - **Demolition** — existing roof tear-off if this is a replacement - **Labor** — per scope with different productivity rates for each layer Manually tracking all of these in a spreadsheet leaves room for errors at every layer. Miss a pitch factor on the area measurement and every downstream material is short. Forget to convert square feet to roofing squares and the bid number is off by 100×. Jobplans eliminates these errors by computing everything from the measurement data with template-driven formulas. ## How to do a roofing takeoff with Jobplans The step-by-step process: 1. **Identify the roof system.** Review the roof plan and roofing specifications. Note the membrane type (TPO, EPDM, BUR, metal, shingle), thickness, attachment method (mechanically fastened, adhered, ballasted), insulation type and R-value, and any special features. 2. **Set the drawing scale per sheet.** Jobplans auto-detects scale from written text on the sheet — title blocks, general notes, and scale callouts. Two-click manual calibration when auto-detect is not reliable. 3. **Measure the roof area with pitch adjustment.** Use the area tool to trace the roof plan outline. For pitched roofs, apply the slope factor (4/12 = 1.054, 6/12 = 1.118, 12/12 = 1.414). Commercial low-slope roofs use 1.00–1.02. 4. **Convert area to roofing squares.** Total area ÷ 100 = squares. Apply waste factor (10–15% commercial, 10% simple residential, 15% complex hip and valley). 5. **Calculate insulation quantities and R-value.** Area × thickness with R-value target. Multiple layers for code-required R-values. 6. **Measure linear flashing runs.** Perimeter edge, parapet walls, penetrations, drains, scuppers, curbs, expansion joints. 7. **Count penetrations, drains, and accessories.** Each penetration is a cost line with material and labor. 8. **Apply labor and export.** Divide quantities by crew productivity (10–20 squares per crew-day for commercial membrane; 3–5 squares per crew-day for shingle). ## 9+ roofing templates with live calculations Jobplans ships roofing templates covering every common system. Each template has the right columns, formulas, waste factors, and default productivity values already wired in. - **TPO single-ply.** Membrane thickness variants (45, 60, 80 mil). Attachment method (mechanically fastened, adhered, ballasted). Seam weld labor. - **EPDM single-ply.** Thickness variants (45, 60, 90 mil). Attachment method. Seam tape or splice cement. - **Built-up roofing (BUR).** Ply count (3-ply, 4-ply), base sheet, interply, asphalt, aggregate surfacing. Hot vs cold applied. - **Modified bitumen.** Torch-applied, hot-mopped, or self-adhered. Cap sheet and base sheet. - **PVC single-ply.** Thickness variants. Similar to TPO workflow with different material cost. - **Metal standing seam.** Panel length, panel width, clip spacing, underlayment, ridge and eave trim. - **Asphalt shingles.** 3-tab or architectural. Bundle count from roofing squares. Starter strip, ridge cap, drip edge, underlayment. - **Tapered insulation.** Slope-to-drain calculations. Layered polyiso with crickets. - **Waterproofing.** Below-grade membranes, deck waterproofing, traffic coatings. Every template handles the full BOM for its roof system — you measure once and every layer's quantities flow into the estimate automatically. ## Square calculations with slope factor A roofing square equals 100 square feet of actual roof surface. For commercial low-slope roofs, the plan area is close to the roof area (factor 1.00–1.02 for drainage slope). For pitched residential roofs, the plan footprint must be multiplied by the slope factor to get true roof area. Common slope factors: - **Low slope (under 2/12):** 1.00–1.02 - **3/12 pitch:** 1.031 - **4/12 pitch:** 1.054 - **5/12 pitch:** 1.083 - **6/12 pitch:** 1.118 - **7/12 pitch:** 1.158 - **8/12 pitch:** 1.202 - **10/12 pitch:** 1.302 - **12/12 pitch:** 1.414 Jobplans applies the slope factor automatically when you enter the pitch on the roof measurement. A 2,000 sq ft plan footprint at 6/12 pitch becomes 2,236 sq ft of actual roof surface, or 22.36 squares. Apply 10% waste and you are ordering 25 squares of membrane. ## Insulation quantities and R-value calculations Insulation is often the single biggest material cost on a commercial roof. Getting it right requires knowing the R-value target, the insulation type, and the board layout. Jobplans insulation templates handle the math automatically. For polyiso at roughly 5.0 R per inch, a code-required R-30 roof needs 6 inches of insulation. That typically means two layers of 3-inch polyiso with staggered seams, so the board count is 2× the roof area divided by board size (32 sq ft for 4×8 boards). For a 10,000 sq ft roof, that is 2 × 10,000 ÷ 32 = 625 boards per layer, 1,250 boards total. Tapered insulation adds complexity. For slope-to-drain on a commercial flat roof, you need a layered stack of tapered polyiso with crickets at drain locations. Jobplans tapered insulation templates compute layer count and board count automatically from the roof area and minimum R-value requirement. ## Flashing and edge metal takeoff Flashing runs are measured as linear footage. Use the linear or polyline tool to trace every flashing run on the roof plan: - **Perimeter edge metal** — runs around the entire roof perimeter - **Parapet wall flashing** — base, counter, and cap flashing on every parapet - **Penetration flashings** — boots and collars for vent pipes, conduit, and equipment - **Curb flashing** — around rooftop equipment like RTUs and skylights - **Drain and scupper flashings** — per drain with termination details - **Expansion joint covers** — linear footage of expansion joints - **Drip edge and starter trim** — perimeter trim for shingle roofs Each linear foot has its own material cost (usually by gauge and profile) and labor. The flashing template in Jobplans tracks all of these with per-foot formulas so the estimate rolls up correctly. ## Penetrations, drains, and accessories Use the count tool for every individual penetration and accessory on the roof: - **Roof drains** — primary and overflow drains, each with body, clamping ring, and dome - **Scuppers** — overflow scuppers at parapet walls - **Vents** — plumbing vents, ridge vents, power vents - **Roof hatches and skylights** — each with counter flashing and sealant - **Equipment curbs** — RTU curbs, exhaust fans, condensing units - **Walk pad sections** — protected walkways around equipment - **Lightning protection** — air terminals and conductors - **Solar PV mounts** — if PV is specified Every count contributes a cost line with material and labor, rolled up to a total penetration cost that is a meaningful part of the overall bid. ## Labor calculations and crew productivity Labor is typically 40–60% of a commercial roofing job cost, and accurate labor estimating separates competitive bids from losing bids. Jobplans labor calculations use crew productivity rates that you can override per company or per project. Typical productivity rates: - **Commercial TPO or EPDM membrane:** 10–20 squares per crew-day (4-person crew) - **Commercial BUR:** 6–10 squares per crew-day (hot work is slower) - **Commercial metal standing seam:** 8–12 squares per crew-day - **Residential shingle roof:** 3–5 squares per crew-day (3-person crew) - **Insulation layering:** 15–25 squares per crew-day per layer - **Flashing installation:** 80–120 linear feet per crew-day These are starting points. Your actual productivity depends on crew experience, project complexity, weather, and access. Track historical productivity data and override the defaults once you have enough projects to calibrate. ## Common roofing estimating mistakes - **Forgetting pitch factor.** Measuring the plan footprint without applying the slope factor on pitched roofs results in material shortages on every scope. - **Mixing up squares and square feet.** A 1,000 sq ft roof is 10 squares, not 1,000 squares. Label units explicitly to avoid this. - **Underestimating waste on complex roofs.** Hip and valley roofs waste more than simple gables. Use the higher end of the waste range (15%) for complex layouts. - **Skipping cover board.** Many commercial specs require a cover board between insulation and membrane — forgetting it is a common oversight. - **Missing penetration details.** Every drain, vent, and curb is a separate flashing scope. Count them individually, not as lump sum. - **Forgetting tear-off labor.** On reroof projects, demolition labor is significant. Budget crew-days for tear-off separately from new installation. - **Ignoring wind uplift requirements.** High-wind zones require enhanced fastening patterns and specific membrane attachment methods that cost more. - **Not including warranty requirements.** Manufacturer warranties often require specific fastener patterns, seam widths, and inspection schedules — bake the cost in. ## Reroof projects and demolition takeoff Reroof projects require an additional layer of takeoff work: the existing roof has to come off before the new one goes on. Demolition takeoff includes tear-off labor, dumpster rental, disposal fees, and sometimes abatement for roofs with older materials that may contain asbestos or lead. For a typical commercial tear-off: - **Tear-off labor** — 20–40 squares per crew-day for single-ply, slower for built-up roofs with aggregate ballast that has to be removed separately - **Dumpster rental** — 30- or 40-yard roll-offs, with haul-away fees and landfill tipping fees per ton - **Roof hauling labor** — crew time to get debris from the roof to the dumpster - **Deck inspection** — allowance for any rotten or damaged deck that needs replacement - **Temporary weather protection** — tarping and drying-in between tear-off and reroofing phases The reroof demolition template in Jobplans rolls all of these into a separate line-item group so you can see the tear-off cost alongside the new roof cost and present it clearly to the owner. Accurate reroof takeoffs are often the difference between winning and losing commercial reroof bids because demolition is where inexperienced estimators most often leave money on the table. ## How Jobplans compares to manual roofing takeoff Manual roofing takeoff for a mid-sized commercial reroof typically runs 4–8 hours with a scale ruler, calculator, and spreadsheet. The estimator measures the roof area, computes squares, figures out the insulation stack, counts penetrations, and transcribes everything into a pricing sheet. Every transcription is a chance for error. Every revision from the architect means redoing the downstream calculations. The same takeoff on Jobplans runs 30 minutes to 2 hours with higher accuracy. Measurements live in the tool, calculations happen automatically with pitch and waste factors applied, and every layer's quantities flow into the estimate without re-entry. Estimators report 3–4× productivity gains on roofing takeoffs after the first week of digital workflow. For roofing subcontractors producing 20–40 bids per year, the compounded time savings free up capacity equivalent to an entire additional estimator without the payroll cost. ## Integration with material cost database and supplier pricing Roofing material pricing shifts constantly, and supplier contracts often include tiered pricing that depends on annual volume commitments. The Jobplans material cost database on the Advanced plan handles both. Import your supplier pricing from a CSV or Excel file and link materials to the roofing templates by category. When you measure a roof, the current unit costs populate automatically. Supplier-specific pricing lets you compare total project cost across suppliers by swapping the active supplier for a material. For a commercial TPO roof, you might compare Carlisle, GAF, and Firestone pricing side-by-side without re-running the entire takeoff. For teams managing annual purchase agreements with multiple manufacturers, this makes vendor selection transparent. ## Who uses Jobplans for roofing takeoffs Commercial roofing subcontractors across TPO, EPDM, BUR, modified bitumen, PVC, and metal systems use Jobplans to produce consistent estimates without juggling separate spreadsheets per layer. Residential roofing contractors handling shingle work use the shingle templates with bundle counts, ridge cap, starter strip, and underlayment all rolling up from a single measurement. General contractors with in-house roofing estimators produce competitive bids without outsourcing to specialty estimators. Independent roofing estimators serving multiple clients use trade templates to deliver consistent quality across every engagement. Waterproofing contractors pricing below-grade foundation waterproofing and deck traffic coatings use the waterproofing templates with membrane coverage rates and primer quantities built in. The common thread is anyone who needs accurate, defensible roofing quantities from a drawing set — faster than a manual takeoff and more reliable than a generic spreadsheet. ## Related guides and comparisons - [Construction takeoff software buyer's guide](/construction-takeoff-software) - [Construction estimating software guide](/construction-estimating-software) - [Measurement tools deep-dive](/features/measurements) - [Material cost database and compositions](/features/materials) - [Trade-specific templates](/features/templates) - [Concrete takeoffs](/trades/concrete) ## Pricing Jobplans Basic is $29/month billed yearly ($348/year, 6+ months free) or $49/month billed monthly.

Divide total roof area by 100 to get square count. For a 24,000 sq ft commercial low-slope roof, that is 240 squares. Apply waste factor (10–15%) to determine order quantity. **How do I apply slope factor to convert plan area to roof area?** Multiply the plan area by the slope factor: 4/12 = 1.054, 6/12 = 1.118, 12/12 = 1.414. A 2,000 sq ft plan footprint at 6/12 pitch equals 2,236 sq ft of actual roof surface. **What waste factor should I use for a roofing takeoff?** Commercial low-slope: 10–12% simple, up to 15% complex. Shingle roofs: 10% simple gable, 15% complex hip/valley. Metal standing seam: 5–8% due to pre-cut panels. **How do I calculate roof insulation quantities?** Area matches gross roof area. Apply R-value and material type for thickness (polyiso ~5.0 R per inch, XPS ~5.0 R per inch). Multiple layers for code-required R-values. **What should be included in a commercial roofing takeoff?** Membrane, insulation, cover board, vapor barrier, fasteners, adhesive, base/counter/cap/edge flashing, drains, scuppers, penetration flashings, walk pads, expansion joint covers, labor, and demolition on reroof projects. **How long does a commercial roofing takeoff take?** Jobplans: 30 minutes to 3 hours depending on complexity. Manual takeoff: 3–5× longer. **What is the difference between mechanically fastened and adhered roofing?** Mechanically fastened uses fasteners and plates to secure the membrane. Adhered glues the membrane with bonding adhesive. Mechanically fastened is faster and cheaper; adhered has better wind uplift performance. **Can Jobplans handle shingle roofs and residential takeoffs?** Yes. Shingle template supports common asphalt products with standard coverage (33 sq ft per bundle 3-tab, 32 sq ft per bundle architectural) and waste factors.
