How does a roofing takeoff turn drawings into a priced estimate?
Roofing estimating services measure each roof plane from the drawings, convert area to squares of 100 square feet, add edge metal, flashing and penetration counts, apply a stated waste factor, and price labor and material with the wage and index sources cited on the sheet.
Our Professional Roofing Estimating Services
Roofing estimating services start with a measurement rule, not a price. We set up the roof square — 100 square feet of finished roof surface, measured on the slope, not in plan — and apply it line by line, so every quantity on the sheet can be traced back to a drawing dimension. Each takeoff arrives as an Excel workbook and PDF summary with marked-up drawing pages showing where the dimensions came from.
We cover Division 07 work across low-slope and steep-slope assemblies, from asphalt shingles and underlayment to membrane and metal systems. The same sheet carries the edge metal, drip edge, flashing and fastener counts that field crews order against, because the roof is only as tight as its perimeter.
Roofing material takeoffs
We measure roof area by slope plane and convert to squares, then break out each layer: decking or sheathing in square feet, underlayment and ice barrier in rolls at published coverage, asphalt shingles in bundles at the manufacturer's per-square rate, and membrane in square feet with seam length in linear feet. Edge metal, drip edge, rake trim, ridge and hip caps, valley flashing and termination bar come off as linear feet with a stated lap allowance. Penetrations, curbs, scuppers and drains are counted by type and size so boots and accessories are not estimated from a lump sum.
Roofing labor cost estimates
Labor is priced by the unit the crew installs — squares of shingle or membrane, linear feet of edge metal and flashing, each penetration flashed — and adjusted with published U.S. wage data for roofers, carpenters and sheet metal workers rather than a flat rate. Pitch and access are stated as inputs, because a 4:12 walkable roof and a 10:12 roof with no staging are not the same installation. The sheet shows the production rate assumed and the hours it produces, so you can test our assumption against your own crew.
Bid-ready roofing cost estimates
The bid package groups work by CSI MasterFormat Division 07 section, separates material, labor and equipment, and carries a stated waste factor per material — typical ranges run higher for shingles and membrane cut-ins than for edge metal. We label the estimate to an AACE estimate class so you know whether it is a budget-order check or a bid-level number. Read it alongside our measured quantity takeoff services when you need the raw measured quantities for your own pricing. To start, send your plans and we quote the fee per project after reviewing them.
What Is Included in Our Roofing Estimates?
Every roofing estimate we produce follows the same structure: components listed by assembly layer, quantities in the trade's own units, then a cost breakdown that separates material, labor and equipment. Nothing is carried as a percentage of another line without showing the arithmetic.
Our roofing estimating services start from the roof plan and the roof squares calculation, where one roof square equals 100 square feet of finished surface. Sloped areas are converted from plan area using the pitch, so a 6:12 slope carries a steeper multiplier than a 3:12 slope, and the sheet shows the multiplier applied to each plane. Linear quantities for eave, rake, ridge, hip and valley are taken separately, because drip edge, ridge cap and valley metal are priced by the linear foot, not by the square.
Materials, labor, equipment and cost breakdowns
The workbook carries four cost columns and a line-item total:
- Material: quantity times unit price, with the waste factor shown as its own column.
- Labor: hours at the trade rate, adjusted with published U.S. wage data and reviewed by an estimator.
- Equipment: staging, hoists, lifts and disposal, listed as line items rather than a percentage.
Material price movement is described in words from the Producer Price Index, and the sheet shows which index family — lumber and wood products, plastic construction products or steel mill products — was used to adjust which line. That is what makes a roof estimate cost auditable rather than a single number. Our thermal and moisture protection estimating team handles the adjacent waterproofing and air-barrier work on the same drawings.
Deliverables and how to send drawings
You receive an Excel workbook, a PDF summary and marked-up drawing pages showing where each quantity was measured. The same workbook doubles as a roof replacement estimate template you can carry into pricing or bid leveling. Send the roof plan, sections, roof details and any specifications; the fee is quoted per project after we review the plans. Related scopes are handled by our gutter and downspout takeoff and waterproofing quantity review teams.
Who Needs Our Roofing Estimating Services?
The estimate is built for whoever signs the subcontract or the change order, and each audience reads a different column. We keep the measurement rule and data source visible so the sheet survives a comparison. Roofing estimating services serve the contractor, the GC and the owner from one measured quantity set, with the wage and price adjustments shown line by line.
Roofing subcontractors
Commercial roofing estimating lives or dies on the edge details, and a roofing contractor bidding a re-roof needs the tear-off, deck repair allowance and curb flashing counted, not assumed. We report pitch and access as stated inputs, because they drive labor hours more than area does. The bid-ready sheet lets you carry your own material pricing and mark-up on top of our measured quantities.
General contractors and home builders
A GC comparing roofing bids needs the scopes aligned before the numbers mean anything — one bid with ice barrier at the eave and another without is not a lower price, it is a smaller scope. Our sheet lists the assembly layer by layer so you can normalize the bids. Home builders use the same format as a roof replacement estimate template for repeat plans, with quantities recalculated per elevation change.
Developers, architects and suppliers
Developers use the estimate at budget stage to test whether a metal panel or membrane assembly fits the pro forma, with the estimate class labeled so the number is not mistaken for a bid. Architects get a check on whether the specified flashing and termination details are buildable as drawn. Suppliers and distributors use the material quantities to plan deliveries and bundle counts per phase. Our professional bid estimating services cover the rest of the trade packages on the same project, and the air barrier and sealant scope that adjoins the roof assembly picks up the lines that sit alongside the roof assembly.
Types of Roofing Projects We Estimate
The measurement rule stays the same across project types; what changes is the assembly, the access and the level of detail the drawings support. Our roofing estimating services state which of those drove the numbers on each sheet.
Residential projects
Steep-slope work dominates: asphalt shingles, underlayment and ice barrier, ridge and hip caps, valley flashing and drip edge, measured by slope plane and reported in squares. Pitch drives both the area multiplier and the labor rate, so a plan-area takeoff without a slope correction is not a roof takeoff. Decking replacement and fascia and soffit repairs are carried as separate line items. Our siding and cladding takeoff covers the wall scope on the same house.
Commercial buildings
Low-slope assemblies — TPO, EPDM and modified bitumen — with insulation and cover board, mechanically attached or adhered, plus curbs, scuppers and drains. A tpo roof takeoff is measured in membrane square feet with seam length in linear feet, because seam labor is a separate driver from field area. Tapered insulation is taken off by thickness zone from the drainage plan, not as a single average.
Industrial and infrastructure projects
Large-footprint metal roofs — standing seam and r-panel — with purlins, clips, fasteners and penetration flashing counted by type, plus translucent panels and curbs. Slope and panel length determine whether runs are continuous or lapped, which changes both material and labor. Our full-scope building estimate handles the structural and site packages around the roof.
Our Roofing Estimating Process
Roof work is priced before the deck is ever seen, so the takeoff has to be built from the drawings and the specification rather than from habit. We run every roofing package through the same three steps, and each step leaves a check an estimator or a project manager can audit later. The sequence below is the one we follow on shingle, single-ply and metal scopes alike.
When a scope includes below-membrane assemblies, we coordinate it with our thermal and moisture protection takeoff so the insulation and vapor layers are not counted twice.
Submit drawings and specifications
Send the architectural roof plan, roof framing or deck plan, the Division 07 specification sections, and any manufacturer details that govern the assembly. Elevations, sections and reflected ceiling plans matter on steep-slope roofs because they carry the eave and rake conditions the plan view flattens. We also ask for the addenda list and the bid form so the estimate lands in the format the owner will read. Use the plan upload page to send the set.
Plan review and digital takeoff
The reviewer checks the slope against the roofing system, confirms the deck type and thickness, and traces each roof area to a closed boundary before any quantity is entered. On-screen takeoff then measures area by slope category, runs the eave, ridge, hip and valley lengths, and counts penetrations, curbs, drains and scuppers one by one. An EPDM roofing quantity takeoff is itemized by membrane width and splice length, not by flat area alone, because lap and flashing waste are real costs. Sheathing and insulation are taken off as separate line items with their own thickness and attachment rules so a substitution does not silently change the price.
Cost calculation, quality checks and delivery
Quantities move into a spreadsheet estimating model that applies material unit costs, waste factors by product type, and labor hours by crew task. A second estimator re-adds the extended costs, checks that every specification section has a matching line, and confirms that the roof squares calculation matches the measured area after slope correction. You receive an Excel workbook, a PDF summary and marked-up drawing pages so each number can be traced back to a sheet. Delivery dates are agreed in writing when the scope is confirmed, and the fee is quoted per project after we review the plans.
Sample Roofing Estimate and Deliverables
The example below is illustrative and uses round numbers so the arithmetic can be checked by hand. It assumes a 40-square asphalt shingle roof replacement on a 6:12 gable, a tear-off to the sheathing, and a one-layer underlayment, with waste already included in the quantities. Unit cost ranges are illustrative placeholders, not current market prices; the real estimate is priced from BLS wage and Producer Price Index data at the time of the takeoff.
Every line carries a unit and a measurement rule, so a reviewer can re-measure the rake, the ridge and the drip edge and land on the same figures. Where the scope touches gutters or wall assemblies, we hand off the adjacent quantities rather than guessing them, which is why the deliverables often sit alongside rainwater collection and disposal takeoffs on the same project.
| Item | Qty | Unit | Unit cost range | Extended range |
|---|---|---|---|---|
| Tear-off existing shingles to sheathing | 40 | square | $60 – $90 | $2,400 – $3,600 |
| Roof sheathing, 7/16 in. OSB, replacement allowance | 12 | sheet | $45 – $65 | $540 – $780 |
| Synthetic underlayment | 42 | square | $18 – $26 | $756 – $1,092 |
| Ice barrier at eaves, 6 ft | 8 | square | $55 – $80 | $440 – $640 |
| Architectural asphalt shingles | 42 | square | $130 – $185 | $5,460 – $7,770 |
| Ridge cap shingles | 120 | linear ft | $4 – $7 | $480 – $840 |
| Drip edge at eave and rake | 320 | linear ft | $2.50 – $4.00 | $800 – $1,280 |
| Fascia board, 1x6, replacement allowance | 160 | linear ft | $6 – $10 | $960 – $1,600 |
| Labor, roofing crew, install and tear-off | 40 | square | $180 – $260 | $7,200 – $10,400 |
| Total | — | — | — | $19,036 – $28,002 |
Excel quantity takeoff sheet
The workbook opens on a summary tab and backs it with one tab per roof area, each showing the measured area, slope factor and converted squares. Line items carry a unit, a measurement rule and a source reference to the sheet and detail they came from. Waste factors sit in their own column so you can see the difference between net and purchased quantity on every product.
Marked-up drawings
Each roof plan comes back with the takeoff overlaid: area boundaries, ridge and rake runs, penetration callouts and flashing extents. The markup is the audit trail for the spreadsheet, and it is the fastest way for a superintendent to check a quantity against the roof they will actually build. Where a detail is missing from the set, the markup flags it rather than assuming a condition.
Itemized cost estimate
The PDF summary lists material, labor and equipment by line, with the extended cost and the total carried forward. It is structured so the numbers can be dropped into a bid form or a client proposal without reformatting. Assumptions and exclusions are written on the same page as the total, so nothing is buried in a footnote.
Software and Pricing Data We Use
A takeoff is only as good as the price behind it, and the price moves. Our roofing estimating services pair measured quantities with published wage and producer price series, then adjust them for the project's location, union or prevailing wage requirements, and site conditions. The chart below shows the Producer Price Index series for the materials in this scope, rebased to 100 so the direction of each series is easy to read against the others.
Because the series move at different rates, a roof package with a standing seam metal roof takeoff and a TPO package can drift apart between bid and buyout. We re-price at the point of estimate and show the index basis in the workbook so a reviewer can see which series drove the number.
Takeoff and estimating software
We work in PDF and on-screen takeoff tools for measurement, spreadsheet estimating models for assembly build-up, and commercial cost databases for baseline unit costs. The takeoff software measures area, length and count against a calibrated drawing scale; the spreadsheet holds the formulas, waste factors and labor constants so the arithmetic is visible. Cost databases supply a starting unit cost that an estimator then reviews against the specification and the local market. No number leaves the sheet without a person confirming it.
Regional material and labor pricing method
Material pricing starts from national averages and is adjusted with the Producer Price Index series shown in the chart below, so lumber, plastic construction products and steel are each carried at their own rate of change. Labor is priced from the BLS wage table below, which shows the trades that install roofing: roofers, carpenters, sheet metal workers and construction laborers. We then apply location factors, prevailing wage determinations where the project requires them, and crew productivity for the roof geometry, including ridge and soffit runs, and the fastener count on a metal panel system. The result is a line-item cost with a stated basis, not a lump sum.
Material price movement, Oct 2023 to Sep 2026
| Occupation | 25th percentile | Median | 75th percentile |
|---|---|---|---|
| Roofers | $22.24 | $26.65 | $31.44 |
| Sheet metal workers | $22.99 | $29.71 | $39.24 |
| Construction laborers | $18.57 | $22.66 | $28.72 |

Why Contractors Choose Our Estimating Services
Roofing is one of the few trades where a single missed flashing detail can wipe out the margin on a whole elevation. Our roofing estimating services are built around the measurement rules that catch those details: slope-corrected area, running lengths at every transition, and a count of every penetration through the membrane. The reasons below are about method, not claims.
A roof squares calculation is the first place errors hide. Plan area divided by 100 is not the square count on a pitched roof until the slope factor is applied, and a 6:12 roof carries roughly 12 percent more surface than its footprint. We show the slope factor on the sheet so the conversion is checkable.
Trade-specific expertise
Single-ply, modified bitumen, shingle and metal each have their own takeoff logic, and we treat them separately. A TPO membrane takeoff is measured by sheet width and run direction, with splice length, termination bar, cover board and fastener quantities carried as their own lines. A standing seam metal roof takeoff runs panel lengths from eave to ridge with the correct panel module, then adds clips, rake trim and closure strips. Hip and valley conditions are measured as linear feet and priced per foot, not absorbed into the field. Adjacent scopes such as thermal and moisture protection takeoffs are coordinated so the same area is not counted twice.
Quality control and clear assumptions
Every estimate goes through a second-estimator check: extended costs are re-added, quantities are cross-checked against the markup, and each specification section is confirmed to have a matching line. Assumptions are written down, including deck condition, tear-off layers and the waste factor applied to each product. Exclusions are listed with the same prominence as inclusions so a bid review has nothing to infer.
Turnaround, communication and revisions
Delivery dates are agreed in writing when the scope and the drawing set are confirmed, and the schedule is set by the size of the roof and the number of assemblies, not by a standard promise. Questions during the takeoff go back to you as a short list rather than as silent assumptions. Revisions are handled against the same workbook, so a revised drawing produces a diff you can read instead of a fresh document with no history.
Roofing Estimating Services Pricing
The fee for our roofing estimating services is quoted per project after we review your drawings and specifications. We do not publish a price list or hourly rate because the scope of a roof takeoff varies with the number of sheets, the number of trades involved, the number of alternates and addenda, and the complexity of the roof geometry. A single-family shingle roof with two hips and one valley is a different exercise from a 200,000 sq ft TPO roof with 40 scuppers, 15 curbs and a tapered insulation layout.
When you send plans, we return a fixed fee for the takeoff and estimate. The fee covers the full roofing material takeoff excel workbook, a PDF summary, and marked-up drawing pages. There is no charge for the initial plan review, and the fee does not change unless the scope changes after we start.
How quotes are calculated
We calculate the fee from the estimated hours to complete the takeoff and estimate. The hours are built from the count of roof plan sheets, the number of roof areas, the number of penetrations and terminations, and the number of specification sections that apply. For example, an EPDM membrane roof with 60 pipe boots, 12 drains and 4 scuppers takes more time to quantify than a similar area of standing seam metal roof with simple ridges and eaves.
The fee is quoted as a lump sum. It is not a percentage of construction cost. We do not mark up material or labor, and we do not sell products.
What affects price and delivery time
Five factors move the fee: the number of drawing sheets and revisions, the number of trades in the package, the number of alternates and unit prices, the complexity of the roof geometry (hips, valleys, dormers, crickets), and the level of detail required (AACE Class 3 or Class 4). Delivery time is not stated here because it is set per project after plan review.
If you need a budget figure before you have a fee, the calculator below lets you test your own assumptions. It asks for building area, your base hard cost per sq ft, soft-cost percentage, contingency percentage and escalation percentage. It returns hard cost, soft costs, contingency, escalation, budget total and all-in cost per sq ft. It contains no prices of its own and no building-type picker; every number comes from you.

Roofing Estimating Services Across the US
Wage levels for roofers, carpenters and sheet metal workers differ by state and metro, and public work often carries prevailing wage requirements that raise the labor portion of a roof replacement estimate template. We adjust labor rates using published U.S. Bureau of Labor Statistics wage data for the project location, and we note where a prevailing wage determination applies.
Material delivery also varies: asphalt shingles, TPO membrane, EPDM membrane and modified bitumen may ship from regional distribution centers, and freight can add to the material cost. Climate and code differences affect flashing details, ice barrier requirements, and drain sizing. We serve all states from one team, so the same takeoff rules apply whether the project is in a cold climate or a hot-humid one. For the waterproofing and thermal scope that sits under the roof, see our thermal and moisture protection estimating page.
Frequently Asked Questions
How much does a roofing estimate cost?
The fee is quoted per project after we review the plans, so it depends on roof area, the number of plan sheets, how many roof systems and elevations are involved, and whether you need alternates priced. Send the drawings and specifications and we return a written quote that states the scope and the deliverable format. No price is fixed until the plan review is done.
How long does a roofing takeoff take?
Delivery is set by the roof area, sheet count, and how many systems or alternates you want priced. We confirm the date in the quote after reviewing the plans, so the schedule you receive is tied to the actual scope rather than a generic promise. Complex roofs with many hips, valleys, and penetrations take longer than a simple gable.
Do you estimate labor and material costs?
Yes. Each line carries a quantity, a unit, and a labor rate adjusted with published U.S. wage data, plus material pricing adjusted with Producer Price Index movement for lumber, plastic construction products, and steel mill products. The workbook shows the arithmetic so you can see how each line total was built and change a rate if your crew or supplier differs.
What drawings do you need?
Roof plans and roof framing plans, building sections and wall sections at the roof, the architectural roof plan showing slopes and drainage, and the specification sections covering Division 07 thermal and moisture protection. Manufacturer details for the membrane or panel profile help. If you only have elevations and a structural plan, send those and we confirm what can be measured.
Can you use my estimate template?
Send the template with the plans and we confirm whether the estimate can be delivered in it. We work in Excel, so most column structures can be matched, including your CSI MasterFormat Division 07 line numbering and your unit columns. If a template depends on formulas or linked workbooks we cannot reproduce, we say so before the quote.
Do you sign NDAs?
Clients can request an NDA before sending drawings, and the terms are agreed before plan review begins. Send the document you want signed with your inquiry so it can be reviewed first. We do not publish a standard NDA policy, so each request is handled as submitted.
What is a roof square and how do you calculate it?
A roof square is 100 square feet of finished roof surface. We measure the sloped area, not the plan footprint, then divide by 100; a 4:12 slope adds about 5.4 percent to plan area and a 12:12 slope adds about 41 percent. Squares drive shingle bundles, underlayment rolls, and membrane coverage.
Do you include waste factors in the takeoff?
Yes, and each one is shown as a separate line so you can see the base quantity and the added percentage. Typical waste runs higher on hip roofs and standing seam metal, where cut panels cannot be reused, and lower on simple gable roofs. You can override any factor in the workbook.
Can you estimate TPO and EPDM membrane roofs?
Yes. We measure membrane field area, then add cover board, insulation, fasteners, termination bars, edge metal, and flashing at curbs, scuppers, and drains. Seam length is taken off the layout rather than estimated from area, because seam welding and primer quantities follow the sheet width you specify.
Do you handle standing seam metal and R-panel takeoffs?
Yes. Panel length and count come from the eave-to-ridge run and the panel width, with rake and hip cuts priced separately. We take off clips, fasteners, ridge and hip closures, gable trim, and the substrate or purlins the panels bear on, so the metal package is complete rather than just the panel square footage.
Can you price a roof replacement from a scope of work instead of drawings?
Yes, if the scope states roof area, existing system, deck type, and the proposed assembly. We build the takeoff from those inputs and flag every assumption in the workbook, such as deck replacement percentage or tear-off layers. A roof replacement estimate template can be used as the starting structure.
Which estimate class do your roofing takeoffs fit?
Most roofing takeoffs sit at AACE Class 3 or Class 2, depending on how complete the drawings are. A Class 3 estimate supports a bid or budget with measured quantities and unit rates; a Class 2 adds more defined specifications and alternates. We state the class and the basis on the summary page.
Do you estimate roofing for all U.S. states?
Yes, we work nationally from plans and specifications, and labor rates are adjusted with published wage data for the trade and region you name. Local code editions differ, so confirm the adopted IBC or IRC edition and any local roof assembly requirements with the building department before pricing.
How do your roofing estimating services handle alternates and unit prices?
Our roofing estimating services price base scope and each alternate as separate sections, so a base bid plus deducts can be read directly from the summary. Unit prices for added deck area or added insulation thickness are carried as rates, letting the owner or GC adjust quantities without a new takeoff.
