So you should essentially see the top edge of the eve or gutter line up with the peak of the roof pitch. The easiest way to measure this section is to divide it up into three different sections: For help determining the area of a sloped roof, see here.

In the united states, a run of 12 inches (1 foot) is used, and pitch is measured as the rise of the roof over 12 inches. How to measure the roof using google earth. We multiply the roof length (c) (which is the sum of building length plus the gable end overhangs of the roof) by the roof width of slope (a) that we just figured out above when we computed the hypotenuse of the roof triangle (that's why we needed the roof rise number).

Determine your roof pitch ( see roofpitch) if you need help. As a tip, if you had hooked the tape measure to the house when you backed away from the wall, you’ll be able to do this without help from someone else!

Extend it upward so it is perpendicular to the level. Measure the inches from the level’s end up to the bottom edge of the rafter. The next step is to measure the pitch (also referred to as the roof slope) of the roof deck.

· make sure you rotate the tape so it is perpendicular to the level. A hip roof split in half fig. Record these values as roof rise over run, with the vertical measurement listed first and the horizontal second.

Also called the roof angle, the roof pitch is defined as the numerical measure of the steepness of a roof, or the ratio of the rise of the roof to the horizontal span. Measure the distance from where you’re standing to the face of the wall you walked away from. To measure a roof, start by measuring the length and width of the building's exterior walls and multiplying them to get the area.

Note the vertical distance on the tape measure and write this value down. Here we show how to use a carpenter's folding ruler to obtain the slope and other dimensions of a roof.

How to use a folding rule to measure angles, roof slope, pitch, area and other dimensions: Then, calculate the pitch of the roof by placing a level against it, angling the level so the bubble is centered, and measuring the distance between the end of the level and the roof. The advantage to this option is that it’s the most accurate, but it involves a little more geometry and math than the other options.
