Standing Water On A Flat Roof

Article Number

5.19

Condition

STANDING WATER ON A FLAT ROOF

Acceptable Performance/Condition

Flat roofs shall be installed to drain water. Standing water on roofs designed for water retention is acceptable.

Warranty

One-Year - Work and Materials

Action

Roofs not meeting the acceptable condition shall be repaired.

Remarks

Flat roofs typically are slow to drain and should be constructed to handle exposure to standing water over short terms. Municipalities can require flow control devices to be installed on roof drains. Some standing water is normal and should generally dissipate after a few days.
