This calculator vs. AccuLynx
Two different shapes: AccuLynx is an account-based platform for running a roofing company's whole sales-to-production pipeline. This page is a free, private worksheet for one question — what should this one low-slope roof cost, given its membrane, its scope, its insulation, and its parapet, before you send the bid.
What each tool is for
AccuLynx is a cloud-based business management platform built specifically for roofing contractors, headquartered in Beloit, Wisconsin. It is built around running a roofing company's whole pipeline in one account: lead capture and CRM, aerial roof measurement, estimating and proposal generation, material ordering with supplier integrations, production and crew scheduling, and job costing, used by a sales team, a production manager, and office staff together across every job the company runs, on an ongoing subscription. It is a large enough business in that niche that in July 2025 Verisk Analytics — the NYSE-listed insurance-data and analytics company — signed a definitive agreement to acquire it in an all-cash deal valued at $2.35 billion, a deal a Delaware Chancery Court later ordered Verisk to complete after a dispute over its regulatory review. AccuLynx's own site is not reachable from this session to confirm today's specific feature list, plan names, or pricing, so only its well-documented identity, category, and the acquisition — reported by Verisk's own newsroom and multiple trade and financial press outlets — are stated here: nothing about it is invented, and no subscription price for it appears on this page.
This calculator does none of that. It does not track a lead, order material, schedule a crew, or hold a record across jobs. It takes one low-slope roof — the membrane kit (TPO 45/60/80-mil, EPDM 60-mil, PVC 60-mil, or two-ply modified bitumen), the scope (recover over existing membrane, full tear-off to deck, or tear-off plus wet insulation), slope and stories, the building's plan length and width converted to roof squares and membrane squares after kit and parapet waste, polyiso insulation layers, parapet flashing by the lineal foot, roof drains, HVAC curbs, walk-pad squares, cover board, loaded labor, mobilization, dumpster, permit, overhead, and the margin you intend to keep — and turns that into the job price, the price per square, the effective hourly rate, and the walk-away price below which the job loses money, plus a printable customer proposal with a deposit split and a price-held date. It runs free in any browser, keeps no account, and uploads nothing you type.
| Question | Where to answer it |
|---|---|
| I run a roofing company and need leads, estimates, scheduling, material ordering, and job costing tracked in one system across every crew and every job. | AccuLynx, or a comparable roofing business platform — running the whole pipeline is not something this calculator does. |
| What should I charge for this flat-roof job, given its membrane, scope, insulation, and parapet? | This calculator — free, instant, private, no account. |
| How much does a full tear-off with wet insulation, a long parapet run, and several drains and curbs actually add over a flat-rate garage-recover special? | This calculator's membrane, scope, insulation, parapet, drain, and curb line items, not a flat per-square price. |
| Is the price I'm about to quote still above my walk-away cost for this job? | This calculator's compare-to-proposed-price check. |
| I need my whole sales and production team working the same leads and paperwork from one shared account. | AccuLynx — built as an ongoing, account-based platform for exactly that job. |
| How does the math behind a flat-roof bid actually work? | This calculator's own pricing walkthrough. |
| Do I need to create an account or sign up to use the tool? | This calculator: no. AccuLynx is used through a subscription account. |
Most low-slope crews get different value from each: AccuLynx (or a comparable platform) for running the company's whole sales-to-production pipeline as an ongoing subscription, and a private calculator like this one for an instant, no-login answer to what one flat-roof recover or tear-off should cost from its membrane, its scope, its insulation, and its parapet before a business system is involved. This page's own figures are a pricing model, not a lead record, a material order, or a building-code determination.
This tool needs no account and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off.
Common questions
Should I use this calculator or AccuLynx?
They do different jobs. AccuLynx, headquartered in Beloit, Wisconsin, is a cloud-based, roofing-only business management platform used by residential and commercial roofing contractors to run a company's whole sales-to-production pipeline: lead and CRM tracking, aerial measurement and estimating, proposal generation, material ordering, production and crew scheduling, and job costing, tied to one account used on an ongoing subscription basis across every job the company runs. It is a large enough business in that niche that in July 2025 Verisk Analytics, the NYSE-listed insurance-data company, signed a definitive agreement to acquire it in an all-cash deal valued at $2.35 billion, a deal a Delaware Chancery Court later ordered Verisk to complete after a dispute over its regulatory review. This calculator does none of what AccuLynx does. It takes one flat-roof job's membrane (TPO 45/60/80-mil, EPDM, PVC, or modified bitumen), scope (recover, tear-off, or tear-off plus wet insulation), slope, stories, plan length and width, membrane and parapet waste, polyiso layers, parapet flashing, roof drains, HVAC curbs, walk pads, cover board, loaded labor, mobilization, dump, permit, overhead, and target margin, and turns that into the job price, the price per square, the effective hourly rate, and the walk-away price below which the job loses money, plus a printable customer proposal, instantly, with no account and nothing uploaded. A roofing company running leads, crews, and material orders across many jobs at once is better served by AccuLynx or a comparable platform; a low-slope crew that wants an instant, private price for one recover or tear-off — membrane, insulation, and parapet included — before a bid goes out is in the right place here.
Does this calculator determine building code, wind-uplift rating, or engineering requirements for the roof?
No. The membrane rates, waste, and insulation figures behind this calculator are common starting points for residential and light-commercial low-slope bids. They are not a building-code opinion, a permit, a wind-uplift rating, or an engineering stamp, and neither this page nor the calculator it describes determines any of those things. Confirm the jurisdiction and a qualified professional before sending a price, especially on multi-story or high-wind-zone work.
Is this page affiliated with AccuLynx?
No. This site is not affiliated with, endorsed by, or sponsored by AccuLynx or Verisk Analytics, Inc. AccuLynx is a trademark of its owner, named here only to describe what this calculator is and is not.
