Climbing up on a house to calculate roof square footage by hand every time you prepare an estimate means you can only cover so much ground after a big storm. It takes time to measure every area and input the information into an estimate, setting you back hours a day.

How to Manually Measure a Roof
To manually measure a roof without the help of aerial measurement reports, you must visit a job site and climb onto the roof to take precise roof measurements by hand.
- Measure the width and length of each plane of the roof (including dormers), and then multiply those numbers to get the correct figure for the square footage of that area.
- Note any skylights, chimneys or other parts of the roof that would not require materials so you can subtract those measurements from your total area.
- Add together the calculated square footage of each surface to get the figure for total square footage of the roof.
- After determining the total square footage of the roof, you must calculate the pitch of the roof by measuring the vertical distance (rise) over a 12 inch horizontal segment (run).
- Write down these numbers as the vertical measurement listed first and the horizontal measurement recorded second so you can find rise over run.
- When you have the total square footage and rise over run of the roof, you can calculate the roof squares to determine how much materials are needed to cover the roof. To calculate the number of squares on a roof, you need to divide its total square feet by 100.
By combining multi-angle aerial images with advanced analytics, our reports provide precise area, pitch, and length measurements. Colour coding distinguishes every detail, from ridges, hips, and valleys to verges, eaves, and flashings. Fast report turnaround saves you time. High-resolution aerial views and 3D diagrams make your tender stand out.
