Roof Cricket Slope Roof Hugh Point

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

Roof cricket slope roof hugh point.

High pitched roofs often need extra fasteners and their pitch can be as high as 21 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. A cricket or saddle is a ridge structure designed to divert water on a roof around the high side of a chimney or the transition from one roof area to another the cricket is normally the same pitch as the rest of the roof but not always. On the roof plan below.

Ommend a roof assembly have positive slope to drain and allow for short durations of ponding water. Smaller crickets are covered with metal flashing and larger ones can be covered with the same material as the rest of the roof. Complete the roof drainage plan below taken from exercise 11 2 showing roof drains crickets directions of slopes magnitudes of slopes and roof high points. Assuming the high point on the central cricket is 6 25 160 mm above the drain level what is the slope of the cricket.

Modify the roof plan so that the slope of the cricket matches the typical slope of the roof. See figure 1 for the ranges of manufacturers acceptable duration policies for ponding for various roof system types. Assuming a slope of 1 4 per foot 1 48 label roof high points. They have a pitch ranging from 4 12 to 9 12.

Add arrows indicating slope. Assuming the remaining roof surfaces slope at 3 8 per foot 1 32 label the roof high pointe. You can also calculate roof pitch even without using a roof slope calculator. Once the primary slope is created crickets are installed both between drains and between the end of the building and the drain to direct water to the outlets.

The slope goes from that point to a high point either at the roof perimeter or at a point between two drain lines. Assuming that the remaining roof surfaces slope at 3 8 per foot 1 32 label the roof high points. Assuming that the high point on the central cricket is 6 2 5 160 mm above the drain level what is the slope of the cricket. If this isn t practical then perform the same measurement on the underside of.

This design is accepted as good roofing practice among industry professionals with the. A dead level surface with a low point that is in a drain line. The slope goes from that point to a high point either at the roof perimeter or at a point between two drain lines. Otherwise the effective slope of the cricket would be compromised by the difference between these two dimensions so as to maintain the 2 4 m 8 ft requirement at the cricket s highest point.

Conventional roofs are the easiest to construct and you can walk on them safely. Providing positive slope many components contribute to a roof system s slope and some elements are outside your responsibility. Assuming the high point on the central cricket is 6 25 160 mm above the drain level what is the slope of the cricket.
