Water Pooling and Ponding on Flat Roof Tiles: Why Should it Be Fixed Immediately?

10 September 2020

Water pooling and ponding should be a primary concern with any type of roofing, including tile since it can occur with any style of roof, home or building, especially during the colder months of the year, unless proper measures are taken. Moisture is the main cause of this issue, and it happens when the heated air inside the building rises into the attic or roof area. This is where the warm air comes into contact with the cooler exterior air to form the water pooling and ponding. When the roof is not designed correctly, the moisture has no escape route and can cause major issues. We provide further facts about the problem of water pooling and ponding, and why should it be fixed immediately.

Water Pooling and Ponding on Flat Roof Tiles Cause Damages

Excessive water pooling and ponding in your roof’s structure encourages mould growth. Mould can spread throughout the area rapidly since it prefers a moist environment to a dry one. When you do not address this issue fast enough, it can affect other parts of your home or building and the health of everyone who frequents it. Also, mould has been known to feed on the organic materials in homes and buildings.

In addition to mould growth, roof water pooling and ponding can cause the structural components of the roof to rot. Wood beams and other parts can start to decay while steel or metal parts can corrode and weaken. As a result, the integrity of your house’s or building’s framework will decrease drastically.

How To Prevent Roof Water Pooling And Ponding

The first way to prevent moisture from accumulating enough to cause water pooling and ponding is to hire a reputable, experienced roofing company to install your tile roofing. It will know the specific setup that your roof requires to prevent this issue.

Adequate roof ventilation is a must to allow the moisture a route to escape from your home and building. An experienced roofing crew knows how to add just the right amount of ventilation without going overboard. Excessive venting can cause heat loss, which increases your heating costs.

While insulating your house or building in a quality fashion can cut down on water pooling and ponding, go one step further and have the roofing crew install a vapour barrier. A vapour barrier is a waterproof membrane that moisture cannot penetrate.

As you can see, roof water pooling and ponding can be a major concern with of roofing materials, including tile roofing, since it is a structural and design issue more than it has to do with the nature of the roofing.
