Understanding Roof Pitches

Roof pitch is what roofers call the angle of the roof relative to a horizontal line.

Understanding roof pitches.

The bottom horizontal line of the triangle is the base of the roof. Roof pitch is indicated by the measure of vertical ascent they ensure for each twelve creeps of horizontal estimation. If the pitch is 1 3 the slope is 8 12. Since a low pitch roof doesn t require as many shingles more often than not a low pitch roof will end up being more.

Mathematically the pitch of a roof is different calculation than roof slope. Low pitch roofs are safer and easier to access when maintenance. Especially for homes in the south a low pitch roof. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

This implies a rooftop that is 4 inches higher than it was 12 creeps back assessing on a flat plane is a four and twelve rooftop. A roof that rises 4 inches vertically for every 12 inches horizontally is said to have a 4 12 pitch. It can be measured in degrees or what is known as pitch. Roof pitch is the rise of the roof over the run of the roof.

And pitch is a fraction derived by dividing the rise by the entire span. The rise is the height of the roof from the base to the top. To calculate pitch you simply divide rise by span and display your result as a fraction. How to measure roof pitch to measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

Pitch is further defined as rise over run. Pitch compares the roof s span to the rise while slope compares rise and run. A roof that ascents six inches each twelve level inches is depicted as a 6 and 12 roof. In this instance we want to take a look at how this can be changed and improved with the help of a roof pitch chart.

If the slope is 4 12 the pitch for the 24 foot span is 1 6. For example if a roof is 8 feet high and spreads out from the center covering 12 feet in each direction the rise over the run would be 8 12. Remember slope is expressed as a ratio and in inches per foot. First measure 12 inches from one end of the level and make a mark.

The roof pitching is essentially how steep the roof is going to be they are either going to be flat or pitched. The lower pitch of the roof means greater walkability.
