If you have a flat roof, you may be wondering what some common problems Flat roofs are susceptible to leaks and ponding water, so it's important to be aware of these potential issues. However, with proper maintenance and care, your flat roof can last for many years. In this blog post, we'll discuss some common problems with flat roofs and how to avoid them. Read on to learn more!

Exposure to Weather

Portland, Oregon is known for its rainy weather. The Portland area gets an average of 36 inches of rain each year, and that rain can cause problems for flat roofs. When water sits on a flat roof, it can seep under the shingles and damage the roof decking. In addition, the weight of the water can cause the shingles to buckle and break. As a result, it is important to make sure that your flat roof is in good condition and that it is regularly inspected for any signs of damage. Taking these steps will help to ensure that your roof can withstand the Portland area's notoriously rainy weather.

Your flat roof is constantly in the sun's UV rays every day, and over time, this can cause some serious problems. UV radiation breaks down the roofing materials, causing them to become brittle and eventually crack. This can lead to leaks, which can not only damage your roof but also your home's interior. In addition, the UV rays can also cause the roofing adhesive to break down, making it less effective at sealing the roof. As a result, your flat roof is more vulnerable to water damage, which can lead to mold and mildew growth. To protect your flat roof from the sun's UV radiation, you should consider investing in a quality roof coating. A good roof coating will reflect the UV rays away from the roof, helping to extend its lifespan.

Ponding Water

Ponding water on flat roofs is a common problem and one that can cause a host of problems if left unchecked. The weight of the water can damage the roof structure, and the standing water can provide a breeding ground for mosquitos and other harmful insects. In addition, ponding water can also lead to the growth of mold and mildew, which can cause health problems for building occupants. While flat roofs are designed to drain water quickly, they can occasionally get overwhelmed during heavy rains. When this happens, it is important to take measures to remove the standing water as soon as possible.

When water pools on a flat roof, it puts additional pressure on the roofing materials. This can cause the seams and flashing to loosen, creating gaps that allow water to seep into the building. In colder climates, ponding water can also cause the formation of ice dams, which can further damage the roof and lead to leaks. As a result, it is important to take steps to ensure that water does not pool on a flat roof for any extended period of time. One way to do this is to install drains or scuppers that will quickly remove any standing water. Another option is to create a sloped surface that will allow water to run off more easily.


When you have a flat roof, it's important to be extra vigilant about maintaining it. Even the smallest leak can quickly turn into a big problem. punctures are one of the most common causes of leaks in flat roofs. They can be caused by everything from falling debris to heavy foot traffic. And once a puncture occurs, it's only a matter of time before the water starts seeping in. The good news is that punctures can usually be repaired relatively easily. However, it's important to act quickly before the leak gets worse. In some cases, a simple patch job may suffice. But if the damage is more extensive, you may need to replace the entire section of roofing. Either way, it's important to address punctures as soon as they occur to prevent further damage to your roof.
