## Accurate Aerial Roof Measurements and Takeoff Report

The Roof Measurement Report provides a detailed analysis of your roof layout and all the critical dimensions. … This report saves your time and enables accurate roof estimates for a roof repair or replacement.

To find your roof’s total square footage:
1. Measure the length and width of each plane on the roof (including dormers) then multiply length times width.
2. Add the square footage of each of the planes together.

### What is aerial measurement?

An Aerial Measuring System plane in the air. The Aerial Measuring System (AMS) is a rapidly deployable capability that can respond to all manner of nuclear incidents and accidents in the United States and overseas.

### How do I calculate roofing materials?

To estimate roofing materials, start by finding the total square footage of the roof and divide the number by 100 to determine the number of “squares” in the roof. Since it takes 3 bundles of shingles to cover a square, plan to purchase 3 bundles for each square. Then, add 10% to the number to account for waste.

How to Calculate Roof Pitch in Degrees
1. First, you need to measure the run of your roof. …
2. Next, you need to figure out the rise. …
3. Now, divide the rise by the run. …
4. Then, divide 1 by your tangent.
5. Finally, multiply this result by 180/π and you’ve calculated your roof pitch!

### How do you measure a roof for a light?

Pretty simple, measure along the roofline either directly at the edge between two people on ladders, along the ground under the roofline, or while walking along the ground with a rolling measure under the roofline edge. These are all fairy precise ways of measuring for your project.

#### What are standard roof pitches?

What are common roof pitches? For a typical roof pitch to use for a traditional house, you should start with the 4/12 pitch cited above, but anything falling in the range between 4/12 and 9/12 is pretty common. If your pitch is lower, you will see it sporting a slight angle, hence the term low-slope roofs for them.

### What does a 4/12 roof pitch mean?

A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a “4 in 12” slope. … The slope can be expressed numerically as a ratio. The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. For example, a “4 in 12” slope can be expressed as the ratio of 4:12
