Which type of flashing includes pan flashing at the window and door seal?

Continuous flashing is the type that includes pan flashing at window and door seals. This method involves a continuous strip of flashing that directs water away from potential leaks. It is particularly effective in preventing water from entering around these critical areas.

Pan flashing, specifically, is a form of continuous flashing that is shaped to capture and channel water away from the window or door frame. This is essential because windows and doors are common points of water intrusion. By using continuous flashing with pan flashing, it ensures that any water that may penetrate the joints will be routed away before it can cause damage.

In contrast, the other types of flashing serve different purposes. J channel flashing is typically used when siding meets a roof or other surfaces and helps accommodate expansion and contraction. Step flashing is applied in a staggered way, commonly in conjunction with roofing practices, to ensure that water flows over shingles rather than under them. Header flashing is designed specifically to protect the top of windows and doors but does not encompass the full pan flashing application that continuous flashing does.
