Low-Slope Roofing Estimator
Generate accurate EPDM, TPO, and PVC material takeoffs in minutes, not hours. Feathers uses AI to produce complete bills of materials with all the components you need — membrane, insulation, fasteners, adhesives, flashings, and more.
You know the pain.
A complex low-slope job can take 2-6 hours to manually calculate. Membrane, insulation, fastener patterns, adhesive coverage, edge details, penetrations... it adds up fast.
Forget a termination bar? Miss the cover strip calculation? Those "small" omissions become expensive change orders that kill your margins and damage client relationships.
GAF, Carlisle, Firestone, Johns Manville, Versico... each has different product names, coverage rates, and compatible accessories. Keeping track of it all is a nightmare.
FM Global requirements, wind uplift zones, energy codes, local amendments... getting it wrong means rejected submittals and costly rework.
AI-powered takeoffs that understand commercial roofing.
