Read a roof's pitch from the ground with your camera, take off squares and shingle bundles, and export a branded PDF before you leave the driveway. Offline.
MEASURE THE ROOF, SIZE THE JOB, KEEP THE RECORD.
Roofing Calculator Pro is a focused roofing calculator — read the pitch, take off the
material, and keep every number with the job. No paper pad, no second app, no
account.
MEASURE THE PITCH
• Pitch gauge — lay the phone on the deck or hold it to a rafter for the angle
in degrees and inches-per-foot, with a haptic lock when the reading settles.
• Pitch from a photo — shoot the gable end square-on from the ground, drag a
line onto the slope, and read the pitch without climbing.
TAKE OFF THE ROOF
• Tape measure — log every run (eave, rake, ridge, hip, valley) on the fast
fraction keypad; it totals the linear feet and can seed the material list.
• Material calculator — plan area, pitch, and waste in; squares, shingle
bundles, underlayment, ice-and-water, starter, ridge and hip cap, drip edge,
and nails out. Coverage and waste presets are editable, and any count can be
overridden.
CHECK THE DETAILS
• Ventilation — attic area with a 1:150 or 1:300 ratio gives required net free
area, balanced intake and exhaust, ridge-vent feet, and soffit count.
• Rafter — run, pitch, and overhang give common and hip/valley rafter lengths,
with the pitch, angle, and slope factor shown together.
• Plumb bob — a true vertical for a chimney, parapet, or wall.
KEEP THE JOB
• Every reading saves to an on-device job ledger — search it, pin it, reopen it.
• Export a clean, branded PDF or PNG, or a .plumb backup, when you choose to.
• English and Spanish, in the app and in the exports.
Free to try for 14 days, then a one-time unlock — no subscription, no ads, no
account. Your jobs stay on the device and leave only when you share or export
them.
MORE FROM PLUMB
Need stairs, concrete, or framing math too? Construction Calc Pro and the rest of the Plumb apps are a tap away in Settings.
A note on accuracy: phone-sensor and photo measurements are a fast field
reference, not an engineering or code determination. Confirm structural,
ventilation, nailing, and safety-critical numbers with calibrated tools and
current local code.
This app hasn’t received enough ratings or reviews to display an overview.
New icon. A steadier, more precise level: smarter sensor filtering, readings taken the moment you tap Save, and less buzzing near level. Plus fixes for saving, importing, sharing, photos, typed fractions (6 5/8), small screens and the Spanish translation.
