Roof Estimate Calculator

Built for residential roofing contractors, RoofBid keeps the bidding workflow in one place. Start a project, record the roof measurements, review your quantities and costs, and create a branded proposal. Save a draft before collecting the customer's signature. YOUR PRICES, YOUR BID Edit the roofing Price Book, add custom items or import supplier prices. Save your own material and labor adjustments by US ZIP prefix. Starter costs are planning estimates, not live supplier quotes or verified local market prices. MEASURE AND DOCUMENT Enter roof measurements, sketch a scaled outline, capture pitch, annotate site photos or attach an existing aerial report. Review quantities before using them in a bid. PROPOSALS THAT STAY CONSISTENT Build editable line items, optional additions and proposal options. Saved proposals preserve their pricing snapshots. Revise a sent or signed proposal without changing the original. Capture signatures on your device. KEEP THE JOB TOGETHER Organize customer records, photos, follow-ups and appointments. Create invoices and change orders, record payments and compare actual job costs with your estimate. RoofBid records payments; it does not process card or ACH transactions.
