Estimate a realistic planning range, see what may be missing from a contractor quote, and compare bids before you commit.
Decking allowance, permits, flashing and workmanship warranty need clarification.
ProjectGauge gives homeowners useful information first. Sharing contact information with a contractor comes later—and only if the homeowner chooses.
Build a planning range using the project size, material, stories, complexity and tear-off assumptions.
Review whether major scope items, allowances, warranties and fees are clearly stated.
Put bids side-by-side, then request another estimate only if you want an additional comparison.
Get a 2026-calibrated planning range. Southern California ZIP codes use a dedicated launch-market model; other ZIP codes use the national planning model.
See where your submitted price falls against the same ProjectGauge planning model, then flag scope items that need clarification.
See the most important differences in one place.
The current beta model is calibrated from 2026 published roofing-cost data. Southern California uses Los Angeles-area material ranges as its local anchor; the national fallback uses current published material-cost guidance. ProjectGauge narrows those broad published figures into a planning band, then adjusts for access, complexity, tear-off and solar handling. We will replace these broad market assumptions with deeper ZIP-level data as usage grows.
