In short

What roofing estimating covers

Roofing estimating is the takeoff and pricing of a roof system from the drawings: the membrane, shingles or metal panels, the insulation and underlayment beneath, and the flashing, coping, edge metal, drains, gutters and downspouts around it. Roof area is measured by slope and system, and every edge and penetration is measured or counted. MassBid Estimation prepares roofing takeoffs and estimates for roofing contractors, general contractors and suppliers, typically in 24 to 48 hours.

You were on a roof all day. The GC wants your number by morning, and the drawings came through at four.

The field of a roof is the easy part to measure: length times width, adjusted for slope. Almost nobody loses money there. Roofing bids go wrong at the edges and the penetrations, where the material is expensive, the labor is slow and the drawings say the least.

Parapet flashing height, coping width, how many drains, whether the curbs are by the roofer or the mechanical contractor, what is under the membrane. A takeoff done in a hurry prices the squares and covers the rest with a percentage.

Four ways a roofing bid loses money

  • 01 · The edges

    Flashing and edge metal covered by a percentage

    Counter flashing, membrane flashing at parapets, coping, gravel stop and drip edge are each a different product and a different labor rate. An allowance treats them as one.

    What changes

    Every flashing and edge condition is measured in feet on its own line, with its height or width.

  • 02 · The pitch

    Plan area priced as roof area

    A roof measured in plan view is smaller than the roof you buy shingles for. The steeper the pitch, the bigger the gap, and steep slopes cost more to work on.

    What changes

    Area is taken off by pitch, so each slope is adjusted and priced at its own rate.

  • 03 · The build-up

    Insulation, cover board and underlayment left off

    What sits under the membrane is often called out only in a note or a detail. On a low-slope roof it can cost more than the membrane itself.

    What changes

    Each layer of the roof assembly is its own line, and anything not shown is flagged as an assumption.

  • 04 · The penetrations

    Drains, scuppers, curbs and vents nobody counted

    Every penetration is flashing, labor and a place for a leak. They are scattered over the roof, mechanical and plumbing plans.

    What changes

    Drains, scuppers, curbs and vents are counted from the roof plan and checked against the mechanical and plumbing sheets.

Then and now

What has changed in roofing estimating

A roof used to be estimated from a tape, a pitch gauge and a price per square. Four things have changed that.

  1. Roofs are measured from drawings and imagery

    New work is taken off the roof plan on screen; reroofs are often measured from aerial imagery. Either way the measurement can be shown, not just stated.

  2. Insulation requirements went up

    Energy codes have raised the insulation required on low-slope roofs. Thicker boards, tapered systems and cover boards have made the build-up a larger share of the job.

  3. Material prices move

    Membrane, insulation and metal prices have been volatile in recent years, and suppliers hold quotes for a short time. Quantities have to stand apart from prices.

  4. Wind and warranty rules shape the detail

    Edge metal, fastening patterns and manufacturer warranty requirements dictate details that used to be left to the installer. They change both quantity and labor.

A real roofing estimate

Roofing cost breakdown for a low-slope commercial roof

Line totals from one finished roofing estimate: a small drive-through building in Oklahoma with about 1,590 square feet of roof work.

Division 07 trade cost came to $21,919, or about $13.79 per square foot of roof. The EPDM membrane itself was $4,195, less than a fifth of that. The insulation beneath it cost almost twice as much, and flashing, edge metal and accessories together came to about $5,000. With general requirements and markups the suggested bid was $35,026.

Figures are from the delivered estimate, labor plus material, rounded to the dollar, with related lines combined. They are specific to that project and are shown to illustrate how a roofing estimate is broken down, not as a price guide.

Real jobs, not a price list. Each figure comes from one project, priced for its own ZIP code and that client's wages, overhead and profit. Prices change by region and over time. Yours will be priced for your location.

Pricing data

Where the prices come from

Quantities are priced from our own pricing database, built with local vendors across the United States. The estimator enters the project's ZIP code and gets current material prices for that market.

Material prices change from region to region and from month to month, so a price book or a national average is out of date before the bid goes in.

  • Priced by ZIP code

    Current local material prices for the place the job is built, not a national average.

  • Updated by vendors

    Local vendors update their prices in the database as they change.

  • Labor as you bid it

    Union, open shop, or Davis-Bacon and prevailing wage rates with fringes.

Questions

Roofing estimating FAQ

It is the takeoff and pricing of a roof system from the drawings. Roof area is measured by system and pitch, insulation and underlayment are added, flashing, coping and edge metal are measured in feet, drains, scuppers and curbs are counted, and labor and material prices are applied to produce an estimate a roofing contractor can bid from.

The roof covering by area, the insulation, cover board and underlayment beneath it, every flashing and edge condition by length, ridge, hip and valley on sloped roofs, drains, scuppers, curbs and vents by count, and gutters, downspouts, soffit and fascia where they are part of the scope.

Area is taken off separately for each pitch and adjusted for slope, so the quantity is the roof surface and not the plan area. On one duplex we took off, the shingles were split into three pitches: 5:12, 2.5:12 and 7:12.

Yes. Low-slope membrane roofs such as EPDM and TPO, asphalt shingle roofs and standing seam metal roofs are all taken off, including buildings that combine them.

The item is priced on a stated assumption and marked as assumed on its own line, so you can see it and change it. Nothing is assumed silently.

It depends on the system and the amount of edge and penetration work. On one small low-slope roof we estimated, Division 07 trade cost was about $13.79 per square foot of roof before general requirements and markups. Small roofs carry more edge per square foot and cost more than large ones.

A single roof starts at $199, and simple scopes typically run $100 to $250. Larger buildings typically run $200 to $500, and large or complex roofs are quoted individually. The quote is free and usually comes back in about 20 minutes.

Yes. This page shows a full sample from a finished job (roofing and sheet metal, for a drive-through building in Oklahoma), which you can open full screen and read page by page. It was built to that client's own specification, so the wage rates, pricing and overhead and profit are theirs. Ask us for a current sample in your own trade.

From our own pricing database, built with local vendors across the United States. An estimator enters the project's ZIP code and gets current material prices for that market, and vendors update their prices as they change. Labor is priced as union or open shop, or at Davis-Bacon rates with fringes on government work.

Yes. The estimate is delivered as an editable Excel workbook with the formulas built in. Change any quantity, rate or markup and the whole estimate recalculates. If overhead and profit was set at 25% and you want 30%, change that one cell and every total updates, so you can adjust your number minutes before the bid is due without sending it back to us.

As many as you need. Every revision is free, including addenda, scope changes and pricing updates, however many times you come back, and there is no time limit. Revisions are handled on priority and are typically returned within an hour to a few hours, depending on the size of the change.

Yes. Every estimate is built to the client's own specification. Send the general contractor's bid form or your own template and the roofing scope is broken out and returned in that format.

Because a roofer's day is spent on roofs, and the takeoff is usually due the next morning. Outsourcing gives a roofing contractor a measured, checked estimate in a day or two without giving up evenings to it.
