What are the three types of flashings commonly found on low slope roofs?

The three types of flashings commonly found on low slope roofs are base, counter, and capping flashings.

Base flashings are installed at roof edges and are crucial for directing water away from the structure. They are typically placed over the roofing material and extend up the wall or parapet to provide a watertight seal at those transition points.

Counter flashings are used to protect the joints where vertical surfaces meet horizontal surfaces, which is particularly important around chimneys, vents, and other roof penetrations. They are layered over base flashings, enhancing the overall water resistance of these areas.

Capping flashings serve to cover the top edges of walls or parapets and are essential for preventing water from seeping underneath roofing materials or into the building. This type of flashing creates a protective cap that helps maintain the integrity of the roof assembly.

These flashings work in concert to create a comprehensive water management system on low slope roofs, minimizing the risk of leaks and damage to the underlying structure.
