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. You can subtract those measurements from your total area.

How do laser measures work?
In a nutshell, laser measurement tools are based on the principle of reflection of a laser beam. To measure a distance, the device emits a pulse of laser in the direction of an object, for example a wall. The time necessary for the laser beam to get to the object and go back determines the measurement of the distance.
Are laser measures accurate?
The Accuracy of Laser Measuring Tools
Most construction lasers will be accurate to 1/8 or 1/16 of an inch. For basic estimating, a laser measuring tape with a 1/8-inch accuracy will work fine. And even if you don’t need to bump the tool up to 1/16-inch accuracy, longer-range models will have it available.
