Mean Roof Height Calculator

As a reminder please don t forget to add height of rafter thickness of roofing material and ridge vent to the number that you ll get using our calculator.

Mean roof height calculator.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. The height h means height above base not height above ground. 45 is a standard value for the slope α for the thickness of the roof r 30 cm are assumed. If your wall has a starting height of 96 8 feet the rake wall will have a total height of 96 62 5 158 5 inches 13 2 1 2.

Calculate the height of your roofing surface using the width and pitch. To determine the y height measure from the bird s mouth up the calculated slope x in 12 to the top of the rafter. At a base width b of 500 cm the height is 292 43 cm. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials. Another simple method is to double the height achieved by the child by age 2 for a boy or age 18 months for girl. Roof calculator calculates height length and width of a gable roof from the angle of slope and the thickness of the roof. The top of the ridge beam m y.

The second calculator above is based on this method. The 62 5 inches is the increase in height for the rake wall from its lowest to the highest point. Visually aama tir a15 14 illustrates the mean roof height as per the image below where h on the sloped roof is ridge height eave height 2 eave height is the distance from the ground surface adjacent to the building to the roof eave line at a particular wall. If this isn t practical then perform the same measurement on the underside of the roof.

For example if your roof is 20 feet wide and has a pitch of 1 2 which means it rises 6 inches in height for every 1 foot of width the height of your roofing surface from base to peak is 10 feet. We included a roof pitch chart below the 7 12 example image and the calculator below that. If this distance measures 4 inches you have a 4 in 12 pitch. 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.

8 inches and you have an 8 in 12 pitch. To determine the finished height of the ridge beam add the rise m and the y height.
