Flat roofs are a great option for both residential and commercial properties. They have excellent durability, but they can also be prone to ponding. Since they are built with a slight slope, they sometimes have difficulty draining water after heavy rains or storms.

Ponding on a Flat Roof

To prevent ponding and its harmful effects, make sure you don’t ignore the water forming on your roof during rain. Here’s what could happen if ponding is left unaddressed.

What Are the Possible Effects of Ponding?

  • An increased risk of ultraviolet (UV) exposure, making your roof vulnerable over time

  • Dirt buildup that could lead to pest infestation, vegetation growth and mud cracking

  • Reduced effectiveness of the adhesives used on your flat roof

  • Premature deterioration of the roof membrane, layers, coatings and flashings

How Can Ponding Be Avoided?

A reliable roofing contractor often emphasizes the importance of preventive maintenance. Take note of these measures to keep your flat roof protected from ponding-related damage:

  • Check every roofing component for defects, damage, leaks or other problems. Do this regularly to keep track of your roofing system’s condition.

  • No amount of water should remain on the surface of your roof for 48 hours or more under dry conditions. Remember that any neglect on your part can void your roofing warranty, so ensure that there is positive drainage on your flat roof.

  • If ponding has already occurred on your roof, do not hesitate to contact roofing professionals. They can inspect and repair your roof and prevent further damage.
