Commercial roofing systems are often much larger and feature flat roofing structure that are less common and use lesser known building materials than residential roofing systems. When these structures get old, they can show some signs that they need to be replaced or need of roof repair Southlake TX contractor can perform, but these are harder to spot in many cases, than with most residential roofs.

One of the main thing you might notice is that the roof is uneven. Pooling can happen in areas where there are larger dents in your flat roof, and the water gathered there can cause even more damage in the long run. Repeated pooling and leaking is a sure sign that spending money on repairs is no longer worth it, and you should simply have your flat roof replaced.

Another sign that it’s time to replace your roof is that it has already reached a certain age. For metal panel roofing, that age can be closer to 50-70 years, while for most other types of commercial roofs – such as bitumen, EPDM or built-up roofing, you can expect an average lifespan of 25-40 years.
