How this service works
Convert roof pitch (rise per 12), angle or percent slope; get the rafter length multiplier and roof area factor.
Output
Returns the roof pitch as rise-per-12, angle in degrees, slope percent, rafter multiplier, optional rafter length in feet (if run provided), and area multiplier — all in a single JSON response.
Example use cases
Estimating materials for a new roof
“I'm pricing out roofing shingles for a 6:12 pitch roof with a 22-foot horizontal run — can you give me the area multiplier and rafter length so I can calculate total surface area?”
Converting architect's angle to pitch
“My architect drew the roof at a 35-degree angle but my framing crew works in rise-per-12 pitch — can you convert 35 degrees to pitch and tell me the rafter multiplier?”
Checking if slope meets code from grade percent
“The grading plan shows a 50 percent slope — what's that in degrees and rise-per-12 pitch so I know if it meets the minimum roof pitch code?”
Technical details
Endpoint
GEThttps://construction-calc.x402tookit.com/roof-pitch?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, accurate roof pitch conversions between rise-per-12, degrees, and percent slope — especially when you also need the rafter multiplier or area factor for material estimation. Prefer this over manual trigonometry or generic math APIs when roofing-specific outputs like rafter length and area multiplier are required.
Side effects
- Missing all three input parameters (pitch, angleDeg, percent) results in an error — at least one must be provided
- Non-numeric or out-of-range values (e.g. negative pitch) may return null fields or a degraded response
- Very large or physically impossible angles (≥90°) may produce null or undefined output values
- Network or payment authorization failure returns a 402 or connection error before any calculation is performed
