±1–2% roof area, ±1–3% wall area, and ±0.5–1% wall height in LiDAR mode. Derived from USGS 3DEP point clouds at 1–8 pts/m². Cross-validated against 28 independent sources. Independent of on-site inspection.
Applies to up to 90% of contiguous US addresses where USGS 3DEP LiDAR coverage exists at 1-meter resolution or better.
A single percentage point of error on a 2,400 sf roof is 24 square feet — nearly a full bundle of shingles. At scale, inaccurate measurements cost carriers millions and expose contractors to scope disputes on every job.
Human measurements vary by adjuster, time of day, and site conditions. ProMeasure delivers the same result every time — ±1–2% repeatability in LiDAR mode. Build underwriting models, pricing tools, and SLAs on measurements that don’t drift.
Every report is cross-validated against 28 independent sources including LiDAR RANSAC plane fitting, multi-date shadow triangulation, Mapillary stereo geometry, and assessor record comparison. A documented methodology that withstands adjuster, carrier, and legal scrutiny.
Under-measure and you lose margin. Over-measure and you risk claim denial. ±1–2% accuracy means material orders land within one bundle of shingles on a typical residential roof — eliminating shortage callbacks and excess returns.
