An Anvilfield app for commercial low-slope roofing foremen, estimators, and reviewers. Android-first, offline in the field, free for two roofs, one-time Pro unlock for fastening-plan PDFs.
Draw the zones on your roof
Enter the roof size, height, wind speed, exposure, enclosure, and assembly allowables. UpliftZone computes edge width a, shades Zone 1, Zone 1 prime, Zone 2, and Zone 3, and shows the uplift pressure for each zone.
Turn pressure into a fastening plan
The app selects a row and in-row spacing for each zone, draws picture-frame rows, and counts fasteners and plates by zone. The Pro export creates a fastening-plan PDF for the bid, crew, or permit file.
Important note
UpliftZone is a layout and estimating aid. Always verify all zones, pressures, and fastener patterns with the membrane manufacturer, a licensed engineer, and your local code authority before installation.
