What does thermal and moisture protection estimating include?
Thermal and moisture protection estimating covers CSI MasterFormat Division 07: roofing membranes and insulation, dampproofing and waterproofing, vapor retarders and air barriers, fireproofing, firestopping, joint sealants and expansion joints, each measured by its own unit with a stated waste factor and drawing reference.
Our Professional Thermal & Moisture Protection Estimating
Division 07 work fails bids in two directions: a membrane area carried without the terminations and flashings that consume the most labor, and a roofing square priced from a national average that ignores the assembly actually specified. Our thermal and moisture protection estimating starts from the drawing set and the project manual, not from a prior job's spreadsheet. Every quantity we publish carries its unit, the measurement rule behind it, and the drawing reference where it was read.
We price Division 07 as a set of assemblies. A TPO membrane roof is measured as membrane, cover board, insulation, fasteners, edge metal, and flashing, each on its own line. Continuous insulation on a wall is measured separately from the sheathing it covers, because the attachment method and the thermal break details drive the labor. The result is a takeoff you can audit line by line against the plans, and our insulation estimates support the wall and roof layers that sit behind the membrane.
Thermal & Moisture Protection material takeoffs
We measure roof areas in squares (100 square feet) and flat work in square feet, then add the linear feet of perimeter, curb, and penetration flashing that the roof plan shows. Below-grade waterproofing is measured by the square foot of wall or slab contact area, with footing and termination details tallied separately. Wall assemblies are broken out by layer: sheathing, air barrier, rigid insulation, and cladding attachment. Each line states the unit, the rule, and the sheet it came from.
Thermal & Moisture Protection labor cost estimates
Labor is built from the crew hours each operation requires, priced with national wage data and adjusted by trade and region. Roofers, sheet metal workers, and laborers carry different rates, so a flashing line and a membrane line are never blended into one labor factor. Production rates are stated per unit — squares per day for membrane, linear feet per hour for counterflashing — so you can see where the hours come from. Material price movement is applied from published index data rather than assumed escalation.
Bid-ready thermal & moisture protection cost estimates
The deliverable is an Excel workbook and a PDF summary with marked-up drawing pages, organized by CSI MasterFormat line so it drops into your bid form. Waste factors are shown as a separate column, not buried in the quantity. We flag scope gaps we find — a roof drain with no clamping ring called out, a parapet with no counterflashing detail — so you can carry or exclude them deliberately. To start, send your plans for review and we will quote the fee per project.
What Is Included in Our Thermal & Moisture Protection Estimates?
A thermal and moisture protection takeoff covers more line items than most bidders expect, because Division 07 collects roofing, waterproofing, insulation, air barriers, fireproofing, and joint sealants under one number. We organize the takeoff by CSI MasterFormat section so your estimator can map each line to the specification it belongs to. Our thermal and moisture protection estimating sits alongside the other trade estimating services we produce, and each sheet follows the same traceable format. Where the scope includes below-grade work, our waterproofing estimating services apply the same measurement rules to membrane and dampproofing areas.
| CSI section | Line item | Unit | Measurement rule |
|---|---|---|---|
| 07 22 00 | Roof insulation, rigid board | sq ft | Roof plan area plus 5% typical waste at perimeter |
| 07 54 00 | TPO membrane | square (100 sq ft) | Field area plus flashing allowance, measured to edge of termination |
| 07 62 00 | Sheet metal flashing and trim | linear ft | Developed length along perimeter, curbs and walls |
| 07 92 00 | Joint sealant | linear ft | Joint length by width from the sealant schedule |
| 07 11 13 | Dampproofing, below grade | sq ft | Wall contact area from footing to grade line |
| 07 21 00 | Continuous insulation, wall | sq ft | Net wall area by thickness, openings deducted |
| 07 81 00 | Spray-applied fireproofing | sq ft | Member surface area from the structural drawings |
Roofing, waterproofing, insulation and sealant components
The takeoff covers roof membranes (TPO, EPDM, PVC, modified bitumen, built-up roofing), roof insulation and cover board, flashing and counterflashing, roof drains and scuppers, and edge metal. Below grade it covers dampproofing, sheet waterproofing, and fluid-applied membrane, measured to the contact area the drawings show. Above grade it covers vapor retarders, air barriers, and continuous insulation in rigid board, mineral wool, or spray polyurethane foam. Fireproofing, firestopping, intumescent coatings, joint sealants, backer rod, and expansion joints complete the division. Where a scope begins with tear-off, we coordinate the removal quantities with professional demolition estimating services so the new membrane area and the disposal volume reconcile.
Areas, squares, linear feet and counts
Roofing is quantified in squares and in square feet of membrane, with flashing in linear feet and penetrations counted by type. Waterproofing is carried as square feet of surface area plus linear feet of termination and footing detail. Insulation is measured by area at each thickness, so R-value changes stay visible. Sealants are taken off in linear feet by joint width, and firestopping by count of penetrating item and assembly type. Every count references the drawing or schedule where it appears.
Materials, labor, equipment and cost breakdowns
Each line separates material, labor, and equipment so you can adjust any one without disturbing the others. Material lines carry quantity, unit, waste factor, and unit cost. Labor lines carry crew hours and the wage basis. Equipment includes roofing kettles, spray rigs, and lifts where the scope requires them. Indirect costs, bonds, and markups are shown as their own rows, never folded into the unit price. The workbook is structured to serve as a Division 07 cost estimate in Excel that your team can edit.
Who Needs Our Thermal & Moisture Protection Estimating?
Division 07 estimates are used by the crews installing the work, the general contractors holding the bid, and the owners deciding whether the scope is funded. Each group reads a different part of the sheet, so we keep quantities, labor, and assumptions separable. Thermal and moisture protection estimating covers a wide scope, from roof membrane to joint sealant, and the sheet is organized so each reader can find their portion.
Roofing and waterproofing subcontractors
Roofing takeoff services matter most to the contractor who has to commit a crew for a season. A roofing takeoff that separates membrane, insulation, and flashing lets you decide which portion to self-perform and which to buy out. Waterproofing and sealant subcontractors use the same sheet to price below-grade work and joint sealant by width and length. If you need the roofing scope alone, our roofing estimating services stand on their own.
General contractors and home builders
General contractors carry Division 07 as a subcontract line and need to know whether the number is complete before they add markup. Our trade estimates show the quantities behind each subcontractor price so you can compare bids on the same basis. Home builders use the residential portion for roofing, insulation, and weather barrier scope across repeated plans. Where the roof assembly changes between models, the line items change with it.
Developers, architects and suppliers
Developers use the estimate to test a budget before design is complete, and AACE estimate class tells them how much contingency the drawing stage warrants. Architects use the takeoff to check that specified assemblies — modified bitumen versus single-ply, mineral wool versus rigid board — are priced as drawn. Suppliers use the quantities to quote membrane and insulation volume. Fireproofing estimates support the structural side of the same package, and our professional trade estimating services cover all three readers without changing the underlying measurement rules.
Types of Thermal & Moisture Protection Projects We Estimate
The measurement rules stay constant across project types; what changes is the assembly, the access, and the detail density. A waterproofing quantity takeoff on a residential basement is a different sheet from a plaza deck over occupied space, even though both are Division 07. Our thermal and moisture protection estimating follows the same discipline either way: unit, measurement rule, arithmetic, and source.
Residential projects
Residential scope centers on steep-slope roofing, underlayment, weather barrier, and batt or rigid insulation, with simple flashing profiles. Quantities are usually driven by roof plane area and linear feet of ridge, hip, and valley. Basement waterproofing is measured from footing to grade, and window and door flashing is counted per opening. Repetition across models makes per-unit pricing practical, and our roofing estimating services carry the shingle and underlayment lines at the same level of detail.
Commercial buildings
Commercial work brings low-slope assemblies — TPO, EPDM, modified bitumen, and built-up roofing — with tapered rigid insulation, cover board, and dense flashing and penetration counts. Air barriers, continuous insulation, and firestopping add lines that residential work rarely carries. Roof drains, scuppers, and expansion joints are counted individually. Our professional waterproofing estimating services cover the below-grade and plaza portions of the same building.
Industrial and infrastructure projects
Industrial scope adds tank and vessel insulation, spray-applied fireproofing to structural steel, intumescent coatings, and heavy-duty joint sealant in traffic areas. Infrastructure work brings bridge deck waterproofing, tunnel membrane, and expansion joint systems measured by linear foot of joint. Access and staging drive labor more than material in these projects, so equipment lines are carried explicitly. The sitework and civil scope around these structures is estimated separately, and thermal and moisture protection estimating stops at the Division 07 line.
Our Thermal & Moisture Protection Estimating Process
Division 07 work fails at the joints more often than in the field of the membrane, so the process starts by separating the two. We read the roof plan, wall sections, foundation details and fire-rated assembly schedules as a set, then build the takeoff so every linear foot of flashing, counterflashing and sealant joint is counted separately from the square footage it protects. That split is the core of thermal and moisture protection estimating: area items priced per square foot or per roof square, linear items priced per foot, and each one traceable to a detail number on the drawings.
Specification review runs alongside the quantity work. Membrane type, insulation thickness and R-value, vapor retarder perm rating, fire-resistive rating and UL assembly design numbers all change the unit cost, and a missing assembly designation is a question we send back before the numbers are finalized. To start the review, send your plans with the Division 07 specifications attached.
Submit drawings and specifications
Send the architectural and structural sheets, the Division 07 specifications, the roof plan with drain and scupper locations, and the finish schedule. We also ask for the fire-rated assembly schedule and any delegated-design performance criteria, because spray-applied fireproofing and single-ply attachment are often specified by performance rather than by product. A short note on the bid date and the scope you are carrying helps us frame the sheet.
Plan review and digital takeoff
The estimator scales each drawing, sets the measurement rule for area items, and traces linear items — base flashing, counterflashing, reglets, expansion joint covers, perimeter sealant joints — with the detail number recorded against each quantity. Insulation takeoff and estimating is kept on its own line set by thickness, since roof insulation, cover board and wall continuous insulation carry different waste factors and labor rates. Dampproofing below slab and on foundation walls is measured from the wall elevation, not from plan area, and firestopping is counted by penetration type and rating. Every quantity carries its source sheet and detail reference.
Cost calculation, quality checks and delivery
Unit costs come from the pricing method described below, then a second estimator checks the arithmetic, the waste factors and the unit of measure on every line. Common catch items are roof squares converted to square feet, membrane laps, and sealant joint depth assumptions. The workbook and PDF summary are returned with the marked-up drawings so you can follow any number back to the page it came from. Revisions against a revised drawing set are quoted as an add to the original scope. If your package also carries the wall cladding, pair this with our siding estimating services, and for the membrane scope itself see our roofing estimates.
Sample Thermal & Moisture Protection Estimate and Deliverables
The example below is illustrative, not a quote. Assume a 40,000 sq ft low-slope roof over a concrete deck: mechanically attached TPO membrane, two layers of polyiso totaling R-30, 1/2-inch cover board, and a perimeter parapet of 400 linear feet. Roof area converts to 400 squares at 100 sq ft per square. Membrane waste is taken at a typical 10 percent, insulation at 5 percent, and the parapet carries base flashing plus counterflashing at 400 linear feet each. Unit costs in the table are illustrative planning ranges and would be replaced with the project's own pricing.
A roofing and waterproofing estimate of this kind separates membrane, insulation, cover board and accessory lines so the owner can see which layer drives the total. Below-grade waterproofing follows the same logic on the foundation sheets: sheet waterproofing measured by wall area, footing and slab junctions by linear foot. Counterflashing is priced per foot including the reglet cut and sealant, and an intumescent coating on exposed structural steel is measured by surface area with the required dry-film thickness stated on the line. The same measurement discipline carries into sitework estimating services when the roof scope sits inside a larger package, and thermal and moisture protection estimating keeps each Division 07 layer on its own row rather than folded into a single square-foot price.
| Item | Qty | Unit | Unit cost range | Extended range |
|---|---|---|---|---|
| TPO membrane, 60 mil, mechanically attached (10% waste incl.) | 44,000 | sq ft | $1.55 – $2.10 | $68,200 – $92,400 |
| Polyiso insulation, two layers, R-30 (5% waste incl.) | 42,000 | sq ft | $1.85 – $2.40 | $77,700 – $100,800 |
| Cover board, 1/2 in. | 40,000 | sq ft | $0.55 – $0.80 | $22,000 – $32,000 |
| Base flashing at parapet | 400 | lin ft | $6.50 – $9.00 | $2,600 – $3,600 |
| Counterflashing with reglet | 400 | lin ft | $7.50 – $11.00 | $3,000 – $4,400 |
| Roof drains, 4 in., incl. clamping ring | 6 | each | $425 – $600 | $2,550 – $3,600 |
| Perimeter sealant joint, backer rod and sealant | 400 | lin ft | $3.25 – $4.75 | $1,300 – $1,900 |
| Subtotal (labor and material combined) | — | — | — | $177,350 – $238,700 |
Excel quantity takeoff sheet
One row per line item with the quantity, unit of measure, measurement rule, waste factor and drawing reference. Roof squares, wall areas and linear feet of flashing sit in separate columns so a reviewer can check the conversion without reopening the plans. The sheet is live, so your estimator can drop in subcontractor pricing against our quantities.
Marked-up drawings
Each drawing page is colored by material and annotated with the quantities we took from it. Detail callouts for counterflashing, roof drains and expansion joints are highlighted where a linear quantity was derived, so a plan discrepancy is visible before the bid goes out rather than after.
Itemized cost estimate
Material, labor and equipment are shown on separate lines with the unit cost and the extension, followed by the subtotal and any stated allowances. Labor hours are derived from the production rates in the pricing method, not entered as a lump sum, so a change in crew size or shift pattern can be tested against the sheet. See the roofing estimating services page for the single-trade version of this deliverable.
Software and Pricing Data We Use
Our tools are ordinary categories used carefully: PDF and on-screen takeoff for measuring and annotating the drawings, spreadsheet estimating for the line-item build, and a maintained cost database for unit rates. The markup stays on the drawing page, so the quantity on the takeoff sheet and the measurement on the plan are the same object. Nothing in the workbook is a typed-over total; each extension is a formula a reviewer can audit. The same discipline carries into siding estimates, where wall areas and trim runs are measured off the elevations rather than scaled from a floor plan.
The chart below shows the Producer Price Index series for the materials in this scope, rebased to 100, so you can see which inputs have moved and by how much. The wage table below carries the national median hourly wages for the trades that install this work.
Takeoff and estimating software
On-screen takeoff handles the area and linear measurement and keeps the detail reference attached to each quantity. The estimating workbook holds the assemblies — membrane plus insulation plus cover board as one roof build-up, sheet waterproofing plus protection board as one wall build-up — and explodes them into individual line items with their own units. Roof drain counts, spray-applied fireproofing areas and sealant joint lengths are entered from the drawings, never estimated from a percentage of floor area.
Regional material and labor pricing method
Rates start from national average unit costs, then adjust for the project's ZIP code, prevailing wage requirements on public work, union status, building height, occupied-building constraints and season. Material lines are adjusted against the Producer Price Index movement shown in the chart below, and labor lines against the wage table below. A commercial roofing bid estimate on a school in a high-wage metro and one in a rural district will not carry the same labor rate, and the sheet shows which adjustment was applied. Every rate is reviewed by an estimator before the workbook is released.
Material price movement, Oct 2023 to Sep 2026
| Occupation | 25th percentile | Median | 75th percentile |
|---|---|---|---|
| Roofers | $22.24 | $26.65 | $31.44 |
| Carpenters | $23.32 | $29.12 | $36.94 |
| Sheet metal workers | $22.99 | $29.71 | $39.24 |

Why Contractors Choose Our Estimating Services
The reasons are procedural. Each Division 07 line carries a unit of measure, a measurement rule and a source reference, so a general contractor reviewing our sheet can challenge a quantity without re-measuring the whole roof. A fireproofing and sealants takeoff is built the same way: rated assembly by rating, penetration by type, joint by width and depth. When the scope includes the wall system, our trade estimating services keep the envelope items on one consistent basis, and below-grade work can be carried through professional waterproofing estimating services on the same measurement rules.
Assumptions are written down rather than buried. Where a detail is ambiguous — a fluid-applied membrane termination height, an expansion joint cover width, a joint sealant depth at a dissimilar-material junction — the sheet states the assumption and flags the drawing it came from, so the bid is qualified in writing before submission.
Trade-specific expertise
Division 07 is measured differently from concrete or steel, and the estimators working on it know the difference between a roof square and a square foot, between membrane lap and field area, and between a counterflashing that is included in the roofing scope and one that belongs to the sheet metal package. That prevents the double-count that shows up as a lost bid or an unplanned buyout.
Quality control and clear assumptions
A second estimator checks every extension, waste factor and unit conversion against the marked-up drawings before release. The workbook includes an assumptions tab listing the specification sections used, the code edition referenced and any item excluded from the scope, so your team can compare it line for line with the subcontractor quotes.
Turnaround, communication and revisions
Delivery dates are agreed when we review the plans and the bid date, and we confirm the date in writing before starting. Revisions are handled against the original workbook so the change is visible rather than folded into a new total, and questions during the bid period go to the estimator who built the sheet. Send your plans with the bid date and the scope you intend to carry.
Thermal & Moisture Protection Estimating Pricing
The fee for thermal and moisture protection estimating is quoted per project after we review your drawings and specifications. There is no rate card, because a two-story office with a single TPO roof and a high-rise with a plaza deck, below-grade sheet waterproofing and a curtain wall air barrier are different quantities of work. We read the sheet list, the Division 07 specifications and the alternates before naming a number.
Use the calculator below to build a square-foot budget from your own 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. The inputs are yours; the calculator holds no prices of its own and does not pick a building type for you.
How quotes are calculated
We price the takeoff first: roof area in squares and square footage by assembly, membrane and cover board quantities, roof insulation thickness and layer count, vapor retarder area, flashing and counterflashing linear feet, and sealant joint feet with backer rod. Each line carries a unit, a measurement rule and a waste factor before labor and material are applied. The fee reflects the number of sheets, the number of Division 07 sub-scopes, alternates and addenda, and how much detail the spec requires at terminations and penetrations. Exterior wall assembly estimating adds a second pass for continuous insulation, air barrier and cladding attachment, which is why envelope-heavy projects carry more fee than a roof-only package. Send the plans through our get a quote page and we confirm scope before quoting.
What affects price and delivery time
Sheet count and drawing scale drive review time; a 40-sheet set with enlarged roof plans and wall sections reads faster than a 200-sheet set with details scattered across architectural and structural sheets. The number of trades in your package matters, since a Division 07 takeoff that also touches firestopping, sealants and expansion joints needs cross-checks against the architectural and structural drawings. Addenda issued close to the bid date extend the schedule, and a firm bid date sets the order of work. We confirm the delivery date with the quote rather than publishing a fixed turnaround. Public work with prevailing wage requirements and projects with many alternates take longer to reconcile. Our professional trade estimating services cover the adjacent divisions when your package crosses scope lines, and civil estimates follow the same line-by-line method when site drainage and paving sit in the same bid set.

Thermal & Moisture Protection Estimating Across the US
Wage levels differ by region, and the wage table below shows national medians for roofers, carpenters, sheet metal workers and construction laborers; we adjust from those published figures rather than from a single national rate. Public projects carry prevailing wage determinations that can sit well above the local median, which changes the labor half of every square of membrane and every linear foot of flashing.
Climate and code drive quantities as much as price. Cold climates push higher roof insulation R-values and a continuous vapor retarder; hot-humid climates shift the same assembly to an air barrier and outward drying. Coastal wind zones raise attachment counts and cover board requirements under IBC Chapter 15 and the referenced UL assemblies, and local amendments change what the building department accepts. Confirm the adopted code edition with the authority having jurisdiction before you bid.
Material delivery is the third variable. Steel mill products, plastic construction products and lumber and wood products have moved at different rates over the past year, and a Division 07 cost estimate excel workbook should show which line items carry those escalators. We serve all states from one team, so a Texas roofing package and a Minnesota roofing package are built on the same takeoff sheet rules. Thermal and moisture protection estimating stays consistent across those states because the unit and measurement rule is fixed before any price is applied. For the full envelope scope alongside the roof, our roofing takeoff services and siding estimating sit in the same workbook, and professional stucco and eifs estimating follows the same takeoff sheet rules for exterior wall assemblies.
Frequently Asked Questions
How much does a thermal & moisture protection estimate cost?
The fee is quoted per project after we review the drawings, because scope drives the work: a single-ply roof plan with tapered insulation prices differently from a full envelope package with below-grade waterproofing, air barrier and fireproofing. Roof area, detail count, number of assemblies and whether you need alternates all move the number. Send the set and we confirm the fee in writing with the quote.
How long does a thermal & moisture protection takeoff take?
The delivery date is set when we quote, after we see the sheet count and how many Division 07 sections are involved. It depends on roof plan complexity, the number of typical details and wall sections, and how quickly questions on unclear assemblies are answered. We confirm the date with the fee, and we do not publish a standard turnaround because scope varies so widely.
Do you estimate labor and material costs?
Yes. Each line carries a quantity, a unit, a material cost and a labor cost built from production rates in the stated unit, such as squares of membrane or linear feet of flashing. Labor is priced from published wage data and adjusted for the market, then reviewed by an estimator. The workbook shows the rate and the arithmetic so you can check any line.
What drawings do you need?
Send the architectural and roofing plans, roof framing and deck plans, wall sections and typical details, the specification sections for Division 07, and any structural drawings showing fireproofing scope. Reflected ceiling plans help with firestopping and penetration counts. If a detail is missing, we list it as an assumption rather than guess at the assembly.
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 line numbering, unit columns and bid summary format. If a template needs formulas or linked tabs we cannot support, we say so before the quote rather than after.
Do you sign NDAs?
Clients can request an NDA before sending drawings, and the terms are agreed before plan review begins. Send the document with your inquiry so it can be executed first. We do not publish a standard NDA policy, so the agreement is handled per client, and drawings are not reviewed until the terms are settled.
Which CSI MasterFormat sections fall under Division 07?
Division 07 covers thermal and moisture protection: dampproofing and waterproofing, vapor retarders and air barriers, roof and wall insulation, shingles and roof tiles, single-ply, modified bitumen and built-up roofing, flashing and sheet metal, joint protection, fire and smoke protection, and sealants. We take off each section separately so the bid summary rolls up by spec section.
How do you handle waste factors on roofing and waterproofing?
Waste is applied per material, not as one blanket percentage. Membrane and sheet goods carry typical waste for cuts, laps and terminations; rigid insulation carries typical breakage and cut waste; flashing and sheet metal are figured by developed length plus laps. Each waste line appears on the takeoff sheet with its basis so you can change it.
Do you take off roof squares or square footage?
Both. Roofing quantities are converted to squares, with the square footage shown alongside, and the measurement rule is stated: field area measured to the drip or wall line, then hips, ridges, valleys and penetrations added by developed length. Insulation is taken off by area at each thickness, so tapered systems show the average R-value and board count.
Can you price fireproofing and sealants in the same estimate?
Yes. Spray-applied fireproofing is taken off by area per UL assembly and thickness, intumescent coating by steel member surface area, and joint sealants by linear feet of joint with backer rod sized to joint width and depth. Keeping these in one workbook lets the bid summary show Division 07 as a single package.
How do you handle below-grade waterproofing quantities?
Below-grade work is measured by wall and slab area from the foundation drawings, with sheet or fluid-applied membrane separated from dampproofing and drainage board. Terminations, penetrations, pile caps and construction joints are counted as details, not absorbed into the field area. Protection board and backfill sequence are noted because they affect labor.
What estimate class do you deliver?
Most takeoffs sit at AACE Class 3 or Class 2, meaning quantities are measured from drawings and priced with unit rates rather than allowances. We state the class and the basis on the cover sheet so the reader knows how much design detail backed the number. If drawings are schematic, we say which assemblies were priced as assumptions.
Can you estimate exterior wall assemblies with continuous insulation and air barriers?
Yes. Wall assemblies are taken off layer by layer: sheathing, air barrier by area including transitions, continuous insulation by thickness and area, cavity insulation by stud space, and cladding attachment. Transitions at roof, foundation and openings are counted as linear feet because that is where air barrier labor concentrates.
How is thermal and moisture protection estimating organized in your workbook?
Thermal and moisture protection estimating in our workbook runs section by section in CSI order, each with a quantity, unit, measurement rule, material cost, labor cost and source note. A summary tab rolls the sections into a bid total, and marked-up drawing pages show where each quantity came from. The PDF summary carries the same numbers for review.
