Use Stair Calculator

How to choose the right calculator

The best calculator depends on the measurement or construction task you are working on.

Estimating roofing work: start with the Roofing Calculator for the relevant roof measurements and material estimate.
Finding roof pitch: use the Roof Pitch Calculator when you know the required rise and run measurements.
Calculating slope: use the Slope Calculator for rise, run and grade-related calculations.
Planning stairs: use the Stair Calculator when working with stair rise, run and layout dimensions.

Roofing & Exterior Calculator FAQs

What can I calculate with these roofing tools?

These calculators cover common roofing and exterior measurements, including roof calculations, roof pitch, slope and stair dimensions. The appropriate tool depends on the measurements and construction task you are working on.

Which calculator should I use to calculate roof pitch?

Use the Roof Pitch Calculator. It is designed for calculating roof pitch from the relevant rise and run measurements.

What is the difference between roof pitch and slope?

Roof pitch describes the steepness of a roof and is commonly expressed as a ratio of rise to run. Slope can describe the rate of vertical change relative to horizontal distance and can be used for roofs, ramps, grades and other applications.

Which calculator should I use for stair measurements?

Use the Stair Calculator for stair-related dimensions and layout calculations.

Are roofing calculator results exact?

Calculator results are estimates based on the measurements and assumptions entered. Actual roofing and construction requirements can vary because of design details, material specifications, waste, overlaps, site conditions and local construction requirements. Verify important measurements before ordering materials or starting work.
