Roof Measurements

What is the standard unit for roofing measurement?

A roofing square is a unit of measurement for calculating the size of a roof and is equivalent to 100 square feet. The larger unit is useful for calculating the amount of material needed for a roof. It’s common to calculate the size of your roof in “squares”, and then order an additional 15% in backup materials.

How do you calculate the rise and run of a roof?

Calculate the roof rise using the figures for unit rise and total run. Multiply your figure for unit rise by your figure for total run to get the total rise. Using the example, it would be six inches times 13 feet. The total roof rise in the example equals 78 inches.

How do I calculate a rise?

Subtract the difference in elevation between two points on a hill to calculate the rise. The elevation could be determined by an altimeter or you could use a topographic map. As an example, you might read 900 feet at the top of a hill and 500 feet at the bottom, so subtract 500 from 900 to get a rise of 400 feet.

What are the 4 types of slopes?

Slopes come in 4 different types: negative, positive, zero, and undefined. as x increases. The slope of a line can also be interpreted as the “average rate of change”.

How to measure your roof area from the ground

A more accurate way to calculate the area of the roof than using Google Earth is to get outside to estimate the roof pitch and the base area of the property. Using these two figures, we can get a good idea of the shingle roof’s square footage and estimate your asphalt shingles’ needs and costs. This DIY technique can be helpful, especially if you are not comfortable getting on your roof, or if you have limited access to it.

Ground measures only work well for a gabled roof, since there are usually just two main rectangular pitches to calculate area for. For more complex roof shapes, like hip roofs, you’ll need to work with a roofer or measure from on top of the roof itself to calculate its total area.
