Roof Pitch Gauge - Gabled

Measure roof pitch instantly using your phone's built-in sensors or camera — then calculate the materials and rafter dimensions you need for any roofing project. ◆ TWO WAYS TO MEASURE • Tilt Sensor — Place your phone on the roof surface for a direct reading. A precision sensor filter (gyroscope + accelerometer fusion) delivers stable, accurate results. • Camera Sight — Stand on the ground and aim at the roofline. On-screen guides help you align while sensors compute the angle automatically. ◆ BUILT-IN BUBBLE LEVEL An animated circular spirit level with a color-coded stability indicator (amber → green → blue) helps you confirm your reading is locked and accurate. ◆ MATERIALS CALCULATOR Enter your pitch and roof dimensions to get a complete materials list: • Squares, bundles, and underlayment rolls • Starter strip, ridge cap, and drip edge • Nails and optional ice & water shield • 9 roofing materials — 3-Tab Shingles, Architectural Shingles, Standing Seam Metal, Corrugated Metal, Wood Shakes, Clay Tile, Concrete Tile, Slate, and Roll Roofing • Minimum pitch validation for each material type ◆ RAFTER CALCULATOR (Pro) Compute everything you need for framing: • Common rafter length, run, and rise • Overhang tail length • Plumb and seat cut angles • Framing square reference marks • Ridge height • Hip/valley rafters with compound angles ◆ REFERENCE TABLES • Pitch Table — 47 entries from 0.5:12 to 24:12 with degrees, slope %, multiplier, and hip/valley factor. Tap any row to use it in the calculator. • Span Tables (Pro) — IRC R802.4 rafter spans for 2×4 through 2×12, SPF #2 and Douglas Fir #2, at 16" and 24" OC. • Unit Converter — Feet & inches ↔ decimal feet/meters, degrees ↔ pitch, slope % ↔ pitch, sq ft ↔ roofing squares. ◆ MEASUREMENT HISTORY Save up to 50 measurements with timestamps, mode (tilt or camera), and custom labels.
