A flat roof can be very durable, but summer can cause damage to a flat roof over time. The heat can lead to all sorts of problems that might eventually necessitate repairs or even a full roof replacement. 

Poor Installation and Poor-Quality Materials

Flat roofs are the most vulnerable to heat if they are not installed properly and if they are not made with high-quality materials. Then, heat can lead to the flat roof sagging. For this reason, it's important to have a flat roof replaced by a roof replacement service.

Thermal Movement

During the summer, temperatures can fluctuate. The temperature tends to be lower in the morning, but it rises throughout the day. These changes in temperature can lead the material that makes up the flat roof to expand and contract. Adding a breathable PVC material can make the temperature fluctuations less damaging to your roof.

Moisture and Blistering

Warm weather can cause your roof to blister because humidity will cause the felt to lift off the roof. If you do not repair the blisters fast enough, the roof could become damaged beyond repair and will need a full roof replacement. 

Mold and Fungus Growth

A hot and humid climate can also cause mold and fungus to grow on the roof. The fungus can damage flashing on the roof. This can reduce the drainage capacity of your roof. Sunlight and high temperatures lead to the mold and fungus growing even more quickly. The best way to eliminate mold and fungus is to remove moisture from the roof. You may also want to apply an anti-fungal chemical to the roof.

Poor Drainage and Damaged Flashing

When a roof is not able to drain properly as a result of a damaged flashing, this can lead to pools of water forming. When this occurs, your roof will become even more damaged and you'll need to replace it sooner. You should not let water sit on your roof for longer than three days. If it won't evaporate on its own, you should manually remove the water. This is best done by a professional because walking on the roof can also cause damage.

If your roof is old or if it is exposed to summer temperatures frequently, you'll need to have your roof undergo more frequent inspections. If you fail to do so, you may need to have your roof replaced sooner than you'd like.
