For roofing contractors

Roofing proposal software for independent contractors.

Quote retail roofing jobs without an insurance-claim workflow. ProJobCalc skips the storm-restoration overhead (that's JobNimbus / RoofSnap territory) and focuses on the workflow most retail roofers actually run: walk the job, write the proposal, send the PDF, mark won.

Three problems Roofing contractors keep hitting.

Problem 1
You're not running insurance claims — you don't need a $79/mo platform built around supplements and ACV/RCV math.
ProJobCalc: $19/mo Pro tier. Same branded PDFs and proposal generator without the insurance-restoration overhead you don't use.
Problem 2
Customers ask 'what's the difference between architectural and 3-tab on my roof?' and you need a defensible price spread, fast.
ProJobCalc: Roofing calculator with material-type spread baked in. Type roof sq ft + pitch + material type, get a price range with labor and tear-off included.
Problem 3
Tear-off, decking replacement, drip edge, ice + water shield — there's a long line-item list every quote needs and missing one costs you 4 hours and $400.
ProJobCalc: Proposal template captures your standard line-item list with default quantities, so every new roof quote starts complete. Adjust the numbers, send.

Roofing questions.

Do you do insurance / supplement workflows?
No. Storm-restoration roofing has its own tooling (JobNimbus, RoofSnap, EagleView) and we're honest about not competing there. If retail / out-of-pocket is your customer base, ProJobCalc is right-sized. See /compare/jobnimbus for the math.
Can I attach photos from the roof to the proposal?
You can attach a photo to a proposal from your phone via the dashboard. Native phone camera direct integration is on the roadmap.
What about EagleView measurements?
No direct integration today — manual paste of the totals into the line items. On the roadmap if there's enough demand from retail roofers (most existing EagleView-integrated tools are insurance-restoration focused).
