Project Roof Pro

Project Roof Pro is a compact, professional roof-truss design tool that runs on your phone, letting roofers, carpenters, contractors and site managers create accurate truss layouts and cutting lists on the spot. Enter spans, end and mid heights, strut counts and beam thickness and the app instantly produces a parametric truss, a CAD-style drawing, and a full cutting schedule ready to export as DXF, PDF or TXT. Because calculations run locally, Project Roof Pro works offline and keeps project data until credits are synced, making it ideal for busy job sites where speed, accuracy and clear documentation matter.

Key Features

⭐ Parametric truss design: define span, mid- and end-heights, number of struts, spacing and material thickness to generate a complete layout and cutting list instantly.

⭐ Four cross-bracing patterns available (Straight, Reverse Straight, Zigzag, Reverse Zigzag) to match common construction details.

⭐ Interactive CAD-style drawing with realistic element thicknesses, vertical cut joints, labeled elements and pinch-to-zoom/pan for on-site inspection.

⭐ Detailed cutting lists showing part names, lengths, total length, bevel and straight-cut info, thickness and quantities, grouped by category for efficient cutting.

⭐ Professional export options: industry-standard DXF with layers, PDF reports for clients and TXT cut lists for quick reference and sharing.

⭐ Project management and pricing: save unlimited projects, browse project statistics, work offline and try the first project free; Project Roof Pro uses a pay-as-you-go credit system (1 credit per meter) with larger credit packs available.

Advantages

✅ Speeds up on-site decisions by delivering instant calculations and ready-to-use cut lists that reduce guesswork and downtime.

✅ Improves accuracy and consistency with labeled drawings, realistic element representation and grouped part lists that cut material waste.

✅ Export and sharing features make it straightforward to hand off DXF/PDF/TXT files to fabricators, clients or team members.

✅ Offline-first operation ensures calculations are available without internet and Project Roof Pro will sync credits when you reconnect.

✅ Flexible pricing and a free starter project let you evaluate results before committing to credits.

✅ Multilingual interface and multiple sign-in options including guest mode simplify adoption across diverse crews.

Disadvantages

❎ Project Roof Pro is a calculation and documentation tool and does not replace a qualified structural engineer for load-bearing analysis and safety checks.

❎ Some export and advanced features require purchasing credits, so ongoing use may incur costs depending on project volume.

❎ The app is designed for experienced professionals; users unfamiliar with truss conventions or cutting angles may face a learning curve.
