What is Pitch Pocket?

Definition of Pitch Pocket in Construction
A pitch pocket is a construction detail that allows the installation of vertical supports on the top of a waterproofed roofing system, without negatively influencing the water tightness of the installation.

Although there are several other construction waterproofing techniques that are being used, the original pitch pocket is still s effective. Basically the technique involves the filling of a pocket or receiving box formed around the vertical support full of an asphalt material creating the pitch pocket. In some instances the need to caulk, with a synthetic caulking material around the vertical support or provide additional flashing is necessary to ensure water tightness.
