Slope Roof Factor

You could calculate the slope factor for every single roof pitch but as a public service many roofing.

Slope roof factor.

You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. Roof pitch refers to the slope which the rafter creates. Roof area in square metres length in metres width in metres slope factor roof area in square feet length in feet width in feet slope factor. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

Climb up the ladder and onto the. The slope factor works with metric and imperial measurements. Valley hip factor. For roof slopes expressed as x in 12 rise in run the roof pitch multiplier is determined by finding the square root of rise run 1.

A roof pitch multiplier also called a roof pitch factor is a number that is multiplied by the area covered by a sloped roof to produce the area of the actual surface of the roof. Roof slope multiplying factors theory and solution of factor. The overall length of the roof or a common rafter from the base to the ridge is. Place your extension ladder against the roof.

How to determine roof slope factor 1. Once you ve figured out the pitch of your roof you can consult the following chart to discover the slope factor and hip valley factor. In construction the slope factor can be used to easily calculate the area of a roof. Hold out your arms and hands perpendicular to the ground as you stand.

A 10 slope roof should not be confused with a 10 pitch roof as a 10 slope roof means that the roof rises by ten inches for every foot of run. The roof slope factor chart also consists of conversion factors to determine the slope of the roof. Examine your roof and look for a safe place to climb.
