4 12 Pitch Hip Roof

For example if you measure 4 inches the pitch of your roof is 4 12.

4 12 pitch hip roof. Enter the pitch of the roof. Rise 12 enter the square foot one pack will cover. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. Hip roof framing hip to common to ridge join diagram ply sheathing angle and cut set back both sheet orientations sheathing hip cut calculator hip roof ply cut angle diagram 1138 93 ft 35 6 sheets 5 10 15 waste 40 sheets.

On a related note the pitch properly the slope of a hip or valley rafter will not be the same as the pitch of the adjacent roof sections. Modern residential hip roof construction uses common pitch ratios in general. This calculator will help you estimate hip roof parameters including rafters and roof area person outline anton schedule 2011 08 29 17 53 20 one of users asked us to create calculator which will help him estimate hip roof parameters like rafter s lengths roof rise and roof area. Ft enter a waste factor.

The roof pitch factor is also used to calculate the length of common rafters. While the slope of the common rafters are expressed as x in 12 the slope of the hip and valley rafter on the same roof will be x in 16 97 so where two roof sections intersect to form a 90 angle a regular hip or valley and each roof. If this distance measures 4 inches you have a 4 in 12 pitch. A roof pitch of 4 in 12 4 12 has a rise of 4 and a run of 12.

Starter strip the perimeter of the roof in lineal feet. The most common hip roof pitch ratios fall between 4 12 and 6 12 although variations occur based on factors such as snow rain and wind conditions which is because steeper hip roof pitch ratios allow for less accumulations of snow and rain on the roof and lower ratios provide less wind resistance. In that case the multiplier is multiplied by the run of the rafter the horizontal distance that will be covered by the rafter. On the roof hold the level perfectly level and measure the height from the roof to the level 12 inches away from where the level touches the surface this will be the rise.

Ridge length top ridge plus the 4 hips in lineal feet. Pitch measurement method 1. Percentage the results roof area total square footage of the roof. Measuring roof pitch 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.

8 inches and you have an 8 in 12 pitch.
