§ Why roofing pros in Philadelphia use Estimate.Pro
THE BID ENGINE.
## Roofing Estimates Built for Philadelphia's Market
Philadelphia roofing work is not generic. You're quoting flat TPO membranes on century-old row homes in Fishtown, steep slate repairs in Chestnut Hill, and full tear-offs on twin houses in Northeast Philly — often in the same week. A generic estimating spreadsheet doesn't account for that range. Estimate.Pro does.
The app walks you through a structured site walkthrough, captures AR measurements on supported devices, and produces a priced scope of work in a median of 8 minutes. You leave the job site with a bid you can send, not a pile of notes to decode later.

## What Makes Roofing Estimating Harder in Philadelphia
**Row home density.** Party walls and shared parapets complicate drainage calculations and membrane termination details. Your scope needs to call out counterflashing, coping cap conditions, and OSHA tie-off anchor points — all on a structure 14 feet wide. Estimate.Pro's roofing workflow prompts you for parapet height, flashing type, and drain count so those line items don't get missed.
**Flat roof dominance.** Philadelphia's housing stock tilts heavily toward low-slope roofs — built-up, modified bitumen, and TPO are common across the row home inventory. The app carries material cost workspaces for each membrane type. You set your supplier pricing once; every future bid pulls from it.
**Philadelphia permit requirements.** The Philadelphia Department of Licenses and Inspections requires a building permit for full roof replacements. Permit fees are calculated on project valuation. Missing that line item in a bid is a margin problem. The app includes a permit/fee field in every estimate so it shows up before you submit, not after.
**L&I compliance and code.** Philadelphia enforces the International Building Code as amended by the Philadelphia Code. For re-roofing, that includes IBC Section 1511 requirements on existing roof replacement, weight limits when adding a new layer, and wind uplift design for the exposure category applicable to the Delaware Valley region. Your written scope needs to reference these conditions. Estimate.Pro's AI-generated scope of work produces plain-language descriptions that you review and edit — it doesn't fabricate code citations, and you can add specific IBC or Philadelphia Code section references in the notes field.

## AR Measurements on Philly Rooftops
On supported devices, Estimate.Pro uses ONNX-assisted live AR measurement to capture roof plane dimensions during your walkthrough. Measurements taken by camera or uploaded photos are flagged as estimates — you always know which numbers are field-verified. For steep-slope work in Germantown or Roxborough where getting on the roof to tape it is a safety issue, that distinction matters.

## From Bid to Invoice Without a Platform Fee
Estimate.Pro runs on Stripe Connect for payment collection. On the Pro plan at $39 per seat per month, the platform fee is 3%. On Elite at $79 per seat per month, the platform fee is 0% — useful if you're processing volume on commercial flat-roof contracts. The Crew plan at $399 per month flat covers your whole crew without per-seat math.
Elite also includes invoice exports and full Stripe Connect workflows, so the same tool that produced the estimate handles the invoice when the job closes.

## Built for 25 Trades, Tuned for Roofing
Estimate.Pro supports 25 trades. The roofing workflow is specific: it prompts for the inputs that matter on a Philadelphia roof — not generic construction fields that leave gaps in your scope. If you also quote gutters, skylights, or sheet metal work, those trades are in the same app.
Philadelphia roofers are competing against licensed contractors who've been working the same zip codes for decades. A faster, cleaner bid doesn't just save you time — it tells the customer you run a tight operation before the job even starts.
