INDEPENDENT ROOFING UTILITY & MEASUREMENT PLATFORM
Free Roofing Calculators & Tools
Roofing Logics provides practical roofing calculators, measurement tools, cost estimators, and easy-to-understand guides for roof pitch, rafters, shingles, roofing squares, materials, and costs.
Popular Roofing Calculators
Roof Pitch Calculator
Convert rise and run measurements into slope ratio, degrees, and pitch multipliers in real time.
Rafter Calculator
Calculate precise rafter lengths, building spans, rises, and overhang extensions.
Shingle Calculator
Estimate total shingle bundles, square requirements, ridge caps, and waste margins.
Roof Square Footage Calculator
Calculate accurate true roof surface area from ground building footprint and pitch factor.
Roofing Square Calculator
Convert roof square footage into standard industry roofing squares (100 sq ft units).
Metal Roofing Calculator
Calculate panel quantities, linear footage, and square footage for metal roofs.
Calculate, Measure & Plan
Calculate
Get immediate, mathematically verified calculations for pitch, slope, rafter spans, and angles without complex manual trigonometry.
Measure
Convert ground footprint dimensions into actual roof surface area, accounting for pitch multipliers and standard waste margins.
Compare
Evaluate lifespan, cost per square, wind resistance, and pitch suitability across asphalt shingles, standing seam metal, and tiles.
Plan
Accurately estimate required material quantities—bundles, underlayment rolls, fasteners, and ridge caps—before ordering.

Why Roofing Logics?
Roofing Logics is built on four core principles:
- Practical Calculation Tools: Focused strictly on solving real-world measurement and estimation problems quickly and accurately.
- Transparent Formulas & Assumptions: Every calculator clearly documents the geometric formulas, code assumptions, and constants used.
- Clear Roofing References: Easy-to-understand charts, tables, and guides designed for homeowners, DIYers, and builders alike.
- Independently Maintained: Free from contractor sales commissions or biased quote generation forms.
