For roofing contractors
Roofing estimates built from measured geometry, not guesswork
Squares, bundles, starter, drip edge, ice and water, ridge vent, pipe boots — roofing estimates live or die on measured edges and penetrations. Drevanto structures that takeoff so nothing falls off the truck list.
The estimating problems you already know
Accessory materials get forgotten
Starter strip, drip edge, flashing kits, and vents are small lines that add up to real money across a season.
Tear-off and disposal are underpriced
Layer count and dumpster logistics belong in the estimate, not in a surprise change order.
Waste varies with roof complexity
Valleys, hips, and pitch change waste; a flat percentage is a starting point, not an answer.
How Drevanto fits
Measured-scope takeoff
Roof-plane area, eaves, rakes, ridges, valleys, and penetrations are explicit estimate inputs, so material lines follow the measurements.
