A traditional pitch pocket resembles a top hat with an open top and bottom. A pitch pocket is a sheet of metal sleeve flashed into the roofing membrane. Manufacturing facilities due to the large number of rooftop penetrations are plagued by pitch pocket problems. Problems with pitch pockets a type of roof flashing used to seal penetrations prevail on all types of roofs but are most typical on built up or modified bitumen roofing systems.

A pitch pocket is the last resort for sealing a roof penetration. The flanges at the bottom of the pitch pocket are fastened to the top of the roof structure with vertical sections that are fitted around the unit pipes or other rooftop equipment installed on the roof. By filling all the gaps between the base of the pocket and the roof the asphalt prevents water from leaking into the roof. Originally coal or tar pitch was used to seal these fixtures to the roof deck which is where the pitch pocket gets its name today installers may pour hot asphalt or grout into the top of the pocket to form a tight seal.

On traditional installations metal boots or pipe sleeves are used for water tight protection but often a specialty flashing is required this is also called a pitch pocket. A pitch pocket is used on both sloped and flat roofs to provide a water tight seal around columns or other roof penetrations. When you have exhausted every possibility for accommodating a roof penetration in a more fool proof way a pitch pocket is the solution. The penetrating object say a small angle penetrates the roof.

Once the edges of the curb are sealed the newly created pitch pocket is ready to be filled using the m thane pourable sealant the sealant will be tack free and water tight typically in 30 minutes to one hour depending on outside weather conditions. Pitch pockets are used for sealing awkward roof penetrations.
