thermoplastic roofingWhen it comes to your business’s success, the exterior of your building is critical. By having a solid roof over your head, you can focus your assets on what really matters rather than pouring money into roofing repairs. This is why it can be frustrating when your flat roof leaks.

If you do spot a leak in your roof, it’s important to work with commercial roofing contractors to pinpoint the cause. This way, you can prevent the issue in the future. The following are just some of the most common reasons why flat commercial roofs leak.

  1. Poor Drainage: This¬†issue often happens when a roof is not installed properly. Flat roofs aren’t actually flat. Rather, they should be sloped just slightly to allow water to drain. This slope is .25 inches of rise for every 12 inches of distance on average. If this structure is off, water can pool and then leak.
  2. Membrane Damage: Most commercial buildings have thermoplastic roofing to prevent water from leaking through. When the membrane is cracked or pulls away from the roof, this protection can be compromised.
  3. Damaged Penetrating Structures: As with other roof types, flat roofs typically have structures coming out of the surface, such as pipes and drains. When these features are installed, they are typically sealed water tight. Over time, this seal can loosen, allowing water through.
  4. Faulty Perimeter Flashing: Weather and other types of damage can loosen perimeter flashing. This can then cause the thermoplastic roofing membrane to pull away from the roof’s surface. When these structures are compromised, water can seep through quite easily. Ignoring this damage can create a ripple effect of other issues.
  5. Age: Sometimes multiple issues spring up at once because the roof is simply getting old. This is why it’s important to note when it’s time for flat roof repair. If you find yourself paying for roof repair often, replacement might be best.

By keeping an eye on your commercial roof and noting when certain features need repair, you can keep your roof functioning for years to come. This will keep the interior of your business dry and moving along as you should. Then you can focus on the most important company operations.
