That’s why having a roofing material that reflects sunlight is important, especially in Southern climates. This breaks down the roof quickly, and leads to warm buildings underneath. Īnd because commercial roofs are often so large they can act as huge UV absorbers. The sun brings a lot of joy to humans, but roofing contractors know that it is one of the main things that degrade a roof. The materials used on flat or low slope roofs need to be durable and able to resist punctures. Other trades are notoriously careless when it comes to working on the roof, and are one of the highest causes of leaks not related to workmanship and aging. Unfortunately, every step holds the possibility of puncturing the roof by stepping on a sharp screw or shard of metal. On top of that, servicemen will need to access them, which creates foot traffic on your roof.
