Ponding
Ponding is water sitting on a roof surface instead of draining off.
Why it matters
Standing water increases leak risk and can shorten roof life.
Where people get this wrong
Ponding is most common on low slope roofs. A small depression can create a big pond over time.
Real-world example
After a rain you still see a shallow puddle on the roof the next day. That is ponding and it deserves attention.
Where this hits your build
This term shows up during construction and affects decisions that are hard to reverse once the work moves forward. Understanding it now saves time, money, and frustration later.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
