The Dangers of Ponding Water

Many homeowners ignore ponding water that appears on their roof, thinking it’s not a major deal if there are no leaks right now. But they couldn’t be more wrong; ponding water is a major problem even if your roof isn’t leaking yet. There are very serious dangers of ponding water that can impact your roof and home greatly if you don’t stop the problem when it first develops. Let’s look at some of the dangers of ponding water to see how you can avoid it.

Ponding water on your home may not seem like a big deal, but it is usually the start of a vicious cycle.

Ponding Water Leads to Leaks in Your Home

When water sits on your roof for more than 24 hours after rainfall, we call that ponding water. Unfortunately, this is a common problem in flat or low-sloped homes due to many different reasons. Sometimes the house settles, sometimes the roof sags, sometimes the roof was installed poorly. Whatever the reason, when you have ponding water on your roof, it can lead to serious leaks on the inside of your home. The constant presence of water will put pressure on tiny holes that can expand them and lead to a leak, and the pressure of the water will force more and more water through that hole until it is a large leak. Homeowners want to avoid roof leaks in any way possible, and one of the best ways to do that is to ensure you don’t have ponding water on your roof.

It Accelerates the Deterioration of Roof Materials

Most roofing systems cannot resist ponding water like a silicone membrane can. Single-ply roofs will begin to thin out, or chalk off under the pressure of ponding water. This basically means that the material is dissipating and will soon be gone. Ponding water also deteriorates acrylic coatings, can lead to mold and rust on metal roofs, and can cause seams to come apart. Simply put: ponding water is a destructive force on your roof.

Ponding Water Adds Stress to Your Homes Structure

Homes are built based on exact calculations and specifications, centered around how much weight is expected to be at certain points on the roof at certain times. Sure, these calculations have room for error, but a constant pressure of ponding water over time can compromise the structural integrity of your home which can lead to major problems.

Ponding Water is a Compounding Problem

If your roof has ponding water, it’s likely to sag a little bit. Once your roof sags, it can hold more water. With more ponding water comes more weight and more sagging. You see where this is going, ponding water leads to more ponding water. In addition, a tiny hole that allows some water to leak into your home will be expanded as more water and more pressure is applied. The leak becomes bigger and bigger until it is a major problem. Ponding water almost always starts small, but grows naturally; that is why it is so important to catch it early.

Conclusion

Ponding water is often underestimated and ignored by homeowners, but it is a major problem that you should pay attention to. It always grows and compounds on itself, and it can really wreak havoc on your home if it is ignored. Give us a call today to see how you can remedy problems caused by ponding water.
