Ponding typically occurs after heavy rains and storms as well as when snow melts. Furthermore, it is common mostly in flat roofing systems. Although no roofing is designed to hold water, flat roofs tend to be more vulnerable because they only have a slight slope for draining water.
That said, when the water has collected on your roof, make sure to address it immediately and find out the reason behind this. Otherwise, your roof may suffer from more extensive damage.
DNB Roofing, a top-rated roofing construction expert, discusses what could potentially happen if you ignore ponding on a flat roof.
What Happens When You Ignore Ponding?
Here are some of the scenarios that may arise in the event that your roof couldn’t drain water properly:
1. Ponding water can cause premature deterioration of your roof membrane, coatings, and flashings.
2. Ponding water can weaken the integrity of your roof, as the adhesives used to make field-fabricated single-ply laps are compromised.
3. Ponding water can function as a magnifying glass that increases your roof’s risk for higher UV exposure. This can damage your roof over time and make it vulnerable to deterioration.
4. Ponding water can attract insects and cause dirt to collect on your roof. This can further lead to vegetation growth or mud cracking.
What Can You Do to Prevent Ponding?
Any roofing contractor will tell you that maintenance is critical in preventing this kind of issue. Whether you have a flat roof or any other type of roof system, you should see to it that every component is checked for signs of problems. In the case of ponding, it’s especially important to look for clogged drains.
Ensure that positive drainage is maintained so that no amount of water is retained for 48 hours or more under dry conditions. Keep in mind that neglecting your roof or ignoring your ponding problem may void your roofing warranty as well.
