Should I worry about ponding water on my flat roof?
If it hasn’t rained for 48 hours and your flat roof still has ponding water, your roof has a problem. This is a big problem because flat roofs are only designed to shed water, not hold water. Sometimes the issue is clogged drains, gutters or downspouts. Flat roofs should contain a slight slope to achieve positive drainage. Ponding water can promote the growth of vegetation and mold, attract insects and can cause serious structural damage to the building.
Regardless of your roof membrane, any roof will experience rapid deterioration when submerged in water. Ponding water damages your roof due to increased UV power from the sun on every component of the roofing system. If you do see standing water on your roof, the first thing you will want to do is to find out what the location is and why it is not draining.
