Common Flat Roofing Problems and How to Avoid Them

Flat roofing systems offer advantages like space utilization and accessibility, but they also come with challenges. This makes it important to be familiar with common flat roofing problems and how to avoid them. At Earl W. Johnston Roofing, we believe in empowering our customers with the knowledge to prolong the life of their flat roofs. In this post, we discuss the prevalent issues these roofs face and offer guidance on how to mitigate them.

Poor Drainage

Flat roofs can accumulate water if the drainage is inadequate, leading to ponding water. This can increase the load on the structure and cause leaks and structural damage over time. Regular roof cleaning and inspections can prevent this kind of problem. In addition, consider tapered insulation or additional drains to improve water flow.

UV Damage

UV rays from the sun can damage flat roofs over time, causing cracks and weakening the roof’s structure. Applying a reflective roof coating can help reduce surface temperatures and protect the roofing material from UV rays and excessive heat, extending the roof’s lifespan.

Thermal Movement and Stress

Temperature fluctuations can lead to thermal movement in roofing materials, causing them to expand and contract. This can result in stress on the roof system, particularly at the seams and joints, potentially leading to leaks and cracks. To avoid these issues, roofing materials should be chosen with thermal movement in mind, and expansion joints should be used where necessary. Regular inspections by local roofers can also identify early signs of stress, allowing for timely repairs before more significant damage occurs.

Membrane Punctures and Tears

Roof damage can occur from foot traffic, equipment installation, and natural debris. In storm-prone areas, it’s crucial to protect the roof membrane. Limit roof access, use walk pads in high-traffic areas, and conduct regular maintenance checks to promptly identify and repair small damage.

Blistering, Ridging, and Splitting

Moisture trapped in roofing layers or between the roof substrate and its membrane can cause problems. In humid areas, poorly ventilated roofs can make this issue worse. To prevent these problems, make sure the roof is properly installed and well-ventilated. Working with your local roof repair company for regular inspections can help address these issues early on.
