A dead level surface with a low point that is in a drain line.

If this isn t practical then perform the same measurement on the underside of. Conventional roofs are the easiest to construct and you can walk on them safely. 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. Smaller crickets are covered with metal flashing and larger ones can be covered with the same material as the rest of the roof.

Assuming a slope of 1 4 per foot 1 48 label roof high points. See figure 1 for the ranges of manufacturers acceptable duration policies for ponding for various roof system types.

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. Assuming the high point on the central cricket is 6 25 160 mm above the drain level what is the slope of the cricket. Assuming the high point on the central cricket is 6 25 160 mm above the drain level what is the slope of the cricket. 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.

The slope goes from that point to a high point either at the roof perimeter or at a point between two drain lines.
