About
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.
