The answer to 'flat roof curling' is that curling or buckling of a flat roof is a common problem caused by a variety of factors. Curling is typically a sign that the roof is reaching the end of its lifespan and may need repair or replacement. Some common causes include age, poor installation, moisture damage, and exposure to UV rays.
Symptoms of a curling flat roof include visible waviness or ripples in the roofing material, gaps or cracks forming at the edges, and potential leaks. If left untreated, a curling roof can lead to further damage and even structural issues. In many cases, calling a professional roofing contractor is recommended to properly diagnose and address the problem.
