What Is A Pitch Pocket In Construction?

A pitch pocket is a type of detail in construction where two sloping roof surfaces meet at a valley. The pocket is a recessed area that is used to channel water from one roof surface to the other.

The pitch pocket provides an opportunity to insulate the roof surface, prevent water from penetrating into the building, and improve the overall weather tightness of the roof.

A Pitch Pocket is a vital component of any roofing system. It is a sheet of metal sleeve that is flashed into the roofing membrane and used for sealing awkward roof penetrations.

Installing a Pitch Pocket can be tricky, but the end result is worth it as it provides an impenetrable barrier from water penetration and helps to maintain the integrity of the roofing system.

Although Rubber Flat Roof doesn’t sell pitch pockets themselves, they do offer the tools necessary to install them securely on rubber flat roofs.

What Is The Purpose Of A Pitch Pan?

A pitch pan is a retrofit roof flashing kit that has a single purpose: to create a secure seal around any odd-shaped penetrations and prevent leaks.

It functions as a container to hold fluid sealant, thus creating a barrier that effectively blocks any water from entering the structure through the penetration.

This product is easy to install and can help maintain the longevity of your roof by acting as an effective safeguard against damage caused by weather conditions or water seepage.

What Does A Pitch Pocket Look Like?

A pitch pocket typically looks like a top hat with an open bottom and top. Flanges located at the bottom of the pocket are affixed to the roof structure using vertical sections that fit around rooftop equipment, pipes, or other objects installed on the roof.

The design of the pitch pocket allows for proper water drainage away from any unit or equipment located on the roof, protecting it from potential water damage should a large storm hit.

What Is The Main Cause Of Pitch Pocket Problems?

The main cause of pitch pocket problems is primarily due to the sealer drying out and shrinking, or structural movement which can compromise the seal.

When the penetration wrapped by the pitch pocket moves or vibrates, it fails to maintain a secure seal over time due to an inability to keep up with the motion, leading to failure.

In order to mitigate such issues, it is important that a good quality sealant is used in combination with proper installation methods and sufficient maintenance.

What Does Pitch Pocket Mean In Carpentry?

A pitch pocket is a cavity found in lumber that has either contained or continues to contain resin. Its primary purpose is to help keep the wood strong and intact as it ages, and it generally ranges from one-eighth inch to two inches wide.

It also helps in keeping the wood clear of any dust, dirt, and debris which might be detrimental to its overall stability.

The presence of pitch pockets can be detected through their distinct discoloration relative to the rest of the lumber, as well as by their scent which may range from sweet like vanilla ice cream to more pungent smells depending on how old they are.

What Is The Main Cause Of Pitch Pocket Problems?

The main cause of pitch pocket problems is typically due to the sealer drying out and shrinking, or structural movement of the penetration that it wraps which can compromise the seal.

If the pitch pocket is not properly installed, with a quality sealer, then it will eventually fail due to normal wear and tear over time.

 

Poor installation techniques, such as leaving gaps between underlying subsurfaces, not adequately cleaning the surface, or using incompatible materials to construct the pocket may also be factors in pitch pocket failure.
