Calculateur de pente de toit

In construction, the 'pitch' of a roof describes its vertical rise relative to its horizontal run. Understanding pitch is vital because it determines which roofing materials can be used (e.g., shingles vs. metal), how fast water will drain, and the complexity of the rafter cuts. In the US, pitch is typically expressed as a ratio over 12 (like 4/12), while engineers may prefer degrees. Our Roof Pitch Calculator provides both, helping homeowners and contractors communicate clearly and ensure their roof meets local building codes for snow load and weather resistance.
