Commercial Roofing Estimating Software Built for Bid Work

Square-foot takeoffs across every roof section, membrane assemblies for TPO, EPDM and PVC, bid packages with alternates, and progress billing that ties back to the estimate.

Everything a Commercial Roof Bid Actually Needs

Section-by-section takeoff

One building, a dozen roof areas, each with its own membrane, slope and detail work. Take off each section separately and let the estimate roll up across the whole project.

Membrane assemblies

Build reusable assemblies for TPO, EPDM, PVC, modified bitumen and built-up — with their own material costs, labor rates, insulation layers and waste factors.

Bid packages with alternates

General contractors ask for base bid plus alternates and unit prices. Produce all three from one estimate instead of rebuilding the numbers in a spreadsheet.

Estimate to pay application

An awarded estimate becomes a schedule of values, then monthly pay applications with retainage tracked — so what you bid is what you bill.

Residential Tools Break on Commercial Work

Most roofing software prices a job the residential way: one roof, one shingle system, a price per square, signature at the table. Point it at a 90,000 sq ft warehouse with four membrane types, tapered insulation and 60 curbs and it falls apart.

Commercial roofing is a bid business. The estimate has to survive scope questions from a general contractor, carry alternates and unit prices, and hold up months later when the job is billing progressively against retainage.

One Platform for Commercial and Residential Roofing

Almost no roofing company is purely commercial. Most run retail replacements and storm work alongside a commercial bid pipeline — and end up with one system for each.

SubcontractorHub runs both. Retail proposals with embedded financing on the residential side. Square-foot takeoffs, bid packages and progress billing on the commercial side. One customer database, one set of costs, one place to see margin.

How a Commercial Roof Estimate Comes Together

1. Measure the sections

Pull areas, perimeters, and penetration counts from an aerial report or field measurements. Each roof area is its own line, because each one is specified differently.

2. Apply the assembly

Choose the membrane system, insulation thickness and attachment method per section. Material, labor and waste come from your own cost library, not a generic national average.

3. Price the details

Curbs, drains, parapets, walkway pads, edge metal and tapered packages are where commercial margin is won or lost. Price them as line items, not as a lump-sum guess.

4. Issue the bid package

Base bid, alternates, unit prices and exclusions in one document — with overhead and target margin applied on top of true cost, so the number holds when the job is awarded.

What Contractors Say

Commercial Roofing Estimating FAQs

What is commercial roofing estimating software?

Commercial roofing estimating software is built for low-slope and flat-roof work bid to a general contractor or building owner, rather than sold to a homeowner at the kitchen table. It handles square-foot takeoffs across roof sections, membrane systems like TPO, EPDM, PVC and modified bitumen, tear-off and insulation layers, and produces a bid package with a schedule of values instead of a one-page retail quote.

How is commercial roofing estimating different from residential?

Residential roofing is priced per square with a shingle system and closed in a single visit. Commercial roofing is priced per square foot across multiple roof sections, each with its own membrane, insulation R-value, attachment method and detail work at curbs, drains and parapets. The bid goes out as a package with alternates and unit prices, the award can take months, and the job bills progressively against a schedule of values with retainage held back.

Does commercial roofing estimating software handle TPO, EPDM, and PVC?

Yes. SubcontractorHub lets you build assemblies for each membrane system you install — TPO, EPDM, PVC, modified bitumen and built-up — with their own material costs, labor rates, and waste factors. You pick the assembly per roof section, and the estimate rolls up automatically across the whole building.

Can it produce a schedule of values and progress billing?

Yes. Commercial roofing is billed progressively, not on completion. SubcontractorHub converts an awarded estimate into a schedule of values, then generates monthly pay applications showing work completed, stored materials, retainage held, and current payment due — so the estimate and the billing never drift apart.

Does it work for contractors doing both commercial and residential roofing?

Yes, and that is the common case. Most roofing companies run a residential replacement business alongside commercial bid work. SubcontractorHub runs both in one platform — retail proposals with financing on the residential side, square-foot bid packages and progress billing on the commercial side — without maintaining two systems.

Can it import EagleView or aerial measurement reports?

Yes. Aerial measurement reports can feed the takeoff so section areas, perimeters and penetration counts do not have to be keyed in twice. That matters more on commercial work, where a single building can carry a dozen separately-specified roof areas.
