How to fix ponding water on a flat roof
Find out the secret to fixing ponding water on your flat roof. It doesn’t have to cost the earth and you really can do it yourself!
After any rainfall lands on a flat roof, water will begin to pool. On a performing flat roof ponding water is not a problem as it will drain, or even evaporate, away. However when your flat roof has uneven areas due to sagging, an insufficient slope, or drainage issues, the ponding water doesn’t dissipate.
Common problems caused by flat roof ponding:
- Degrading roofing materials, particularly on older modified and built up roofs
- Extra stress and damage to the load bearing structure due to the extra weight of the water
- In winter freezing standing water will expand causing more damage
- Where seams overlap the ponding water can cause the membrane to lose it’s seal, allowing water in underneath
- Stagnant water allows moss, algae and debris to collect and provides a breeding ground for insects
