How It Works
From address to bid-ready BOM in three steps.
Enter the Project Address
Feathers geocodes the address, auto-determines wind speed, climate zone, exposure category, and applicable codes (IBC, ASCE 7, HVHZ, TDI, FM). You confirm — or override with your own numbers.
Configure the Roofing System
Select membrane type, manufacturer, attachment method, deck type, insulation target, and warranty level. Smart-filtered dropdowns prevent invalid combinations. Set project-wide defaults, then override per section for mixed-system buildings.
Get a Complete, Traceable BOM
Every line item — membrane, insulation, fasteners, edge metal, accessories — is calculated deterministically and cited to its source: manufacturer spec, FM approval, or code section. Export to PDF bid document or Excel.
Built for Estimators Who Need to Be Right
Every feature designed around the workflow of commercial roofing estimation.
Deterministic Calculations
Zone areas, wind uplift, fastener patterns, membrane quantities, insulation layers, and edge metal — calculated from first principles using ASCE 7 and manufacturer-specific rules. Not AI-generated estimates.
Manufacturer Coverage
Assembly rules and fastener patterns seeded from Mule-Hide and Versico installation manuals. Every BOM line traces to the specific manufacturer spec and FM approval document used. Additional manufacturers are added as their rules are validated and coverage is confirmed.
Confidence Scoring
Every field in the estimate is tagged confirmed, assumed, or blocked. The Feathers Verified badge requires both geometry and BOM confidence above 90%. You always know what's solid and what's an assumption.
Professional Exports
PDF bid documents with executive summary, clean BOM table, assumptions section, source citation appendix, and the Feathers Verified badge when the estimate qualifies. Excel export for purchasing.
