Complete Roofing Business Platform
TARC delivers a full suite of professional tools built specifically for Australian roofing contractors. From AI-powered satellite analysis and detailed estimation to client management, invoicing, and supplier integration — everything you need to estimate, manage, and grow your roofing business in one platform.
Every calculator shares the same traced roof profile, so you measure a property once and the dimensions flow into quotes, gutters, flashing, ventilation, pitch and load reports automatically. Every export is a consistent, branded, client-ready PDF.
AI-Powered Full Estimator
Our flagship 4-step estimation wizard combines AI satellite analysis with floor plan uploads and 2D tracing. The AI uses DSM height data + RGB edge fusion to detect every roof plane, ridge, hip, valley, and eave — generating professional Blocking and Flashing Layout diagrams with per-face confidence scores and a complete Bill of Quantities.
- AI Satellite Analysis: Enter an address — DSM + RGB data fusion detects roof planes, ridges, hips, valleys, and eaves with confidence scores
- Professional Diagrams: Auto-generated Blocking Layout (coloured face polygons) and Flashing Layout (ridge/hip/valley lines with measurements)
- Floor Plan Tracing: Upload floor plans and use 2D tracing tools for precise manual measurements
- Trace Once, Use Everywhere: Saved roof profiles can be loaded into any of the other 12 calculators — no re-measuring required
- Nett Roofing Quantities: Accurate ridge, hip, valley, and eave lengths computed from face polygons
- BOQ + Supplier Matching: Automatic Bill of Quantities matched to 6,500+ Lysaght products
- Professional PDF Reports: Multi-page reports with diagrams, cutting lists, and material breakdowns
Roof Profile Tracer
Trace a roof once on the satellite image and save it as a reusable Roof Profile. That same profile loads into every other TARC calculator — gutters, flashing, pitch, ventilation, weather loads, insulation and quoting — so you never re-measure the same property twice.
- High-Resolution Satellite: Google Solar API imagery loaded straight into the tracer canvas
- Click-to-Trace Faces: Draw each roof face in seconds — automatic m² and per-face pitch
- Saved & Shared: Profiles are saved to your account and auto-appear in every calculator's "Load Roof Profile" menu
- Link to Projects: Optionally attach a profile to an existing project so the Full Estimator can pick it up too
