Flat roofs are a common feature in modern architecture, offering a sleek aesthetic and space for rooftop amenities. However, they also come with unique maintenance challenges. Here are some specific repairs you may need for a flat roof.

Ponding Water

One of the most common issues with flat roofs is ponding water. This occurs when water collects on the roof after rain, leading to excess weight and potential leaks. Unlike pitched roofs, where water naturally drains off, flat roofs may need additional drainage systems or slight slopes to prevent ponding. If you notice pools of water on your roof 48 hours after it rains, you may need to call a professional to assess and repair the issue.

Surface Degradation

Flat roofs often face direct sunlight, which can cause surface degradation over time. The UV rays can cause the roofing materials to break down, leading to cracks and leaks. To prevent this, you may need to apply a UV-protective coating to your roof. This is a specific repair you might only need on a flat roof, as pitched roofs typically have shingles or tiles that provide some degree of UV protection.

Membrane Blisters

Flat roofs are typically covered with a waterproof membrane to prevent leaks. However, over time, air or moisture can get trapped under the membrane, causing it to blister. These blisters can eventually rupture, leading to leaks. Repairing them involves cutting out the blistered section, replacing it with new material, and then re-sealing the membrane.

Flashing Issues

Flashings are components used to seal roof system edges, perimeters, penetrations, walls, and other areas from water penetration. On flat roofs, flashing issues are quite common due to the lack of slope, which can lead to water pooling around these areas. Over time, the flashing may corrode or separate from the roof surface, leading to leaks. Repairing or replacing the flashing is crucial to maintain the integrity of a flat roof.

Drainage Problems

Proper drainage is crucial for flat roofs. Without it, water can pool on the roof, leading to structural damage and leaks. Over time, drains can become clogged with leaves and other debris, or they may not be adequate for the size of the roof. In such cases, you might need to repair or upgrade your roof's drainage system.

Owning a building with a flat roof comes with unique maintenance and repair requirements. Regular inspections are key to catching and addressing these issues early. By understanding these potential problems, you can ensure your flat roof remains in good condition for years to come. Always remember that while some minor issues can be fixed with a DIY approach, many repairs require the expertise of a professional roofer. Don't hesitate to call in the professionals when needed to maintain the longevity and durability of your flat roof.
