Why is the use of pitch pockets discouraged in roofing systems?

1. A They are prone to water leaks

2. B They require frequent maintenance

3. C They are not aesthetically pleasing

4. D They are costly to install

The correct answer is: B They require frequent maintenance

The use of pitch pockets is discouraged primarily because they are prone to water leaks. Pitch pockets, which are typically used for sealing around pipe penetrations or other rooftop structures, can collect water rather than providing an effective barrier. Over time, the sealant within these pockets can deteriorate, and if the water finds its way into the roofing system, it can lead to significant leaks, structural damage, and deterioration of roofing materials. While maintenance concerns might arise, the critical issue with pitch pockets is their inherent vulnerability to leaks, which can result in more severe and costly problems down the road. In many cases, roofing professionals recommend other methods of sealing and flashing that offer better waterproofing capabilities and long-term durability.
