RoofingCalc Pro vs RafterMate

RoofingCalc Pro is the professional roofing calculator built for roofers, contractors, and estimators who need fast, accurate answers on the job site — no internet required. Four powerful calculators in one app. Punch in your measurements, get precise results, and export a clean PDF estimate you can hand to your client or attach to a claim file. Works completely offline — even on top of the roof. FOUR CALCULATORS: 1. ROOF AREA & MATERIALS Enter your roof footprint dimensions and pitch. Get the exact roof area in square feet AND in roofing squares (1 square = 100 sq ft). Instantly see how many bundles of shingles, rolls of underlayment, and ridge cap pieces you need. No more guessing at the supply house. 2. PITCH CALCULATOR Enter rise and run — get pitch as a ratio (e.g. 6/12), in degrees, and as a percentage. Or enter any one value and calculate the others. The slope factor and hip/valley factor are shown so you can use them in your own calculations. Covers every pitch format roofers use. 3. RAFTER LENGTH Enter the run and pitch — get common rafter length, hip rafter length, and valley rafter length. Accounts for the correct geometric factors (slope factor for common rafters, hip/valley factor for hip and valley rafters). Cut your lumber right the first time. 4. JOB COST ESTIMATOR Enter roof area, material costs per square, labor rate, and waste factor. Get a complete job breakdown: materials cost, labor cost, waste allowance, and total job price. Perfect for quick on-site estimates and formal bids.
