Mean Roof Height Calculator

Mean roof height calculator. The second calculator above is based on this method. One of them is adding 2 5 inches 7 6 cm to the average of the parent s height for a boy and subtracting 2 5 inches 7 6 cm for a girl. 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.

The height h means height above base not height above ground. 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. Another simple method is to double the height achieved by the child by age 2 for a boy or age 18 months for girl. 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.

The 62 5 inches is the increase in height for the rake wall from its lowest to the highest point. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. If your goal is to only calculate the roof height do not enter any numbers in wall height field and only use building width and roof pitch fields. If this distance measures 4 inches you have a 4 in 12 pitch.

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. 45 is a standard value for the slope α for the thickness of the roof r 30 cm are assumed. 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. To determine the finished height of the ridge beam add the rise m and the y height.

Roof pitch calculator results explained. At a base width b of 500 cm the height is 292 43 cm. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. We included a roof pitch chart below the 7 12 example image and the calculator below that.

If this isn t practical then perform the same measurement on the underside of the roof. Roof calculator calculates height length and width of a gable roof from the angle of slope and the thickness of the roof.
