We designed the porch with wide overhangs for shade from the hot north carolina summer sun. Cut a 2 inch by 4 inch board that s 2 feet long then cut a slope into the board to match the slope of the cricket. Crickets are also often referred to as saddles in this context.

Cut 3 4 inch plywood to fit that triangle space for both sides. Depending on the roof surface slope there is an accepted maximum length to width ratio. The porch joined the house at right angles to a shed roof section. Most roof s have a pitch in the 4 12 to 9 12 range.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. We began by tearing off the shingles and removing a skylight from the shed roof. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. The functionality of the cricket is determined by the cricket valley slope.

The roof cricket is normally the same pitch as the rest of the roof but not always. Measure the triangle along the sides of the cricket beam the length up the roof the width against the chimney and the angle between the outside of that line and the top of the cricket beam. Cricket panel slope is typically double the roof surface slope. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page.

As this angle increases the cricket valley slope increases resulting with more effective drainage. For a 4 in 12 slope measure 4 inches down from one end of the 2 inch by 4 inch. Since roof drains are rarely placed in the lowest point of a structural sloping roof deck crickets are usually needed. Without crickets the area between the drain and the wall remains low and collects water.

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. Roof crickets are found on the high side of a chimney or when one roof meets another.

Roof crickets can be covered with metal flashing or with the same material as the rest of the roof.
