William Gibson Posted: Jul 25, 2011 12:18 PM	Roof Cricket All: working on a bid for a roof. Have a low-sloping roof that slopes down to a 2nd level building. The building was an after-thought and obviously roof drainage wasn't thought about. The building spans 24' of the roof. Looking to build a cricket to keep the water to the right and/or left of the building. Do you find it easier to make a site-built cricket, buy a pre-built cricket, or build up the SPF to form a cricket?
mason Posted: Jul 26, 2011 09:13 AM	I posted this earlier on my forum It is easier to spray in crickets, not to mention that it would be an integral part of the roof and not another mechanically fastened assembly that could be a source of problems later on. The technique takes some practice. You want to start by spraying the center of the cricket first in the shape you want, then spray another layer of foam just slightly larger on the next pass and continue until you have the cricket the size required. Spray the foam in 0.5 inch lifts and make sure to let it cool before installing the next pass to prevent too much exothermic heat from developing. Try practicing on the ground first until you feel comfortable with the shape and size.

Roof Cricket

All: working on a bid for a roof. Have a low-sloping roof that slopes down to a 2nd level building. The building was an after-thought and obviously roof drainage wasn't thought about. The building spans 24' of the roof.

Looking to build a cricket to keep the water to the right and/or left of the building.

Do you find it easier to make a site-built cricket, buy a pre-built cricket, or build up the SPF to form a cricket?
