Roofing Calculator All In One

Smart roof framing, rafter, pitch, material and cost calculations.

This Roofing Calculator is an all-in-one calculator for roofers, carpenters, contractors, builders, estimators, property owners, and DIYers. Simple to use—plan your roof projects with confidence.

Calculate roof dimensions, rafter measurements, pitch, rise, run, overhang, ridge details, hip and valley lengths, jack rafters, birdsmouth references, roofing materials, waste, labor, and estimated project costs. Select your roof type, enter your measurements, and get clear results with helpful 2D drawings and basic 3D previews.

📐 Roofing Calculation Tools
Supports multiple roof types and framing layouts:
- Gable roofs
- Common rafter roofs
- Hip roofs
- Valley roofs
- Pyramid hip roofs
- Saltbox roofs
- Dutch gable roofs
- Gambrel roofs
- Mansard roofs
- Hexagonal roofs
- Cross-L gable roofs
- Cross-L hip roofs

Results may include roof pitch, pitch angle, rise and run, common/hip/valley rafter lengths, jack-rafter measurements, ridge length, roof area, overhang, plumb-cut angle, seat-cut reference, birdsmouth reference, framing-member quantities, and roofing-material estimates.

🖼️ Visual Tools
2D plan and elevation views, basic 3D isometric previews, common-rafter layouts, ridge/hip/valley lines, jack-rafter positions, birdsmouth and seat-cut/plumb-cut diagrams, measurement labels, and zoom/pan controls—so you can review roof geometry before cutting or ordering materials.

🧱 Material Estimator
Estimate rafters, ridge boards, hip/valley members, fascia boards, sheathing/plywood sheets, roofing coverage, underlayment rolls, fasteners, and waste allowance. Adjust waste percentage to match your roof shape and material type.

💰 Cost Estimator
Enter your own local prices to calculate framing, sheathing, roofing, underlayment, and fastener costs, plus labor cost, material subtotal, and estimated total project cost. Editable anytime for different suppliers, locations, and budgets.

📁 Project Management
Save projects with client name, address, roof type, notes, calculations, estimates, and costs. Reopen, update, rename, duplicate, pin, delete, search, filter, sort, and view recent projects.

📄 Reports & Exports
Generate project summaries, measurement reports, framing cut lists, material reports, and cost reports. Export as PDF or CSV, save PNG drawing snapshots, print, or share—you stay in control of where files go.

📏 Flexible Measurement Settings
Imperial or metric, decimal or feet/inches (with fractions), adjustable precision, and custom fraction denominators—built for both US-style and metric roofing workflows.
