The summer heat can be the final push to failure for old flat roofs, especially those made from felt or bitumen. The stresses that flat roofs experience during hot weather may cause more problems in winter.
In this post, your local roofers at Goodrich Roofing discuss common problems that flat roofs may experience during summer.
1. Blistering – Water can penetrate through cracks or holes on the roof. Once it’s exposed to heat all day, the felt can lift from the surface. Blisters can be treated if they’re discovered early by replacing the affected areas of felt. The longer the blisters are there, the harder they would be to repair. In this case, replacement would be the best option. It should be addressed early because blistering can lead to bigger roofing problems.
2. Thermal Movement – The continuing heating and cooling cycles in summer can cause traditional flat roofs to expand and contract. This will allow water to easily seep into the roof. However, single-ply PVC membrane is designed to create a 100% watertight covering that withstands natural elements. This roofing material is also not affected by condensation.
3. Faulty Installation – Roofs that aren’t properly installed are more likely to experience heat-related damage. Flat roofs that are installed too flat or made of poor quality materials can sag in the middle, allowing rainwater to pool. Water will eventually penetrate through a crack or hole caused by thermal movement. Most licensed roofers, including Goodrich Roofing, are extensively trained to prevent this from happening so you can be assured the job is done right the first time. We only use top-grade materials from the country’s top roofing manufacturers.
4. Flashing Damage – Fungal growth and moisture buildup are the two major causes of flashing damage. Fungi grow faster in the summer as they need sunlight to survive. Have your roof inspected, and immediately complete the necessary repairs. Proper drainage is essential in making sure your roof lasts. Damaged flashing can eventually cause your flat roof to fail.
5. Standing Water – It’s one of the major causes of water leaks in flat roofs. Standing water will begin to damage your roof if it doesn’t drain within 72 hours.
