Avoiding Ponding Water on Commercial Roofs

Manchester is a great city, but it also has a reputation for being one of the wettest cities in the UK. Despite the fact we’ve had one of the driest and hottest summers ever, heavy rain will always be commonplace in Manchester, especially with the winter months coming up.

Rainfall on commercial buildings can often lead to an accumulation of water that hasn’t properly ran off the roof, something flat roofs are particularly susceptible to. Many commercial roofing companies will attest to how much severe damage ponding water can lead to, on any commercial roofing or industrial roofing system in Manchester, the North West or anywhere in the UK for that matter.

With this in mind, we wanted to look into how you can avoiding ponding water on your commercial or industrial roof in Manchester.


What is ponding water? And why can it lead to problems?

Ponding water is unfortunately one of the most common issues facing many commercial roofing or industrial roofing systems in Manchester. This is because many of these properties have flat roofs, which only have a very slight pitch, meaning water from rainfall can’t always drain away as efficiently.

When this water accumulates and remains on the roof for 48 hours or more, this is what’s known as ponding water. Even if there aren’t any actual leaks, ponded water on the roof can still lead to various problems and significant damage, including:

  • Accelerated deterioration of the membrane surface.
  • Potentially damaging vegetation and algae growth.
  • Premature failure of the roof system.
  • Decrease in insulation thermal resistance.
  • Potential for damage to the interior of the building.
  • Deformation of the roof deck structure due to increased load.
  • Accumulation of debris and other contaminants. 

Preventing ponding water

Avoiding these problems and preventing ponding water, all comes down to proper roof design. Any commercial roofing or industrial roofing system in Manchester, or the UK, which has not been designed or installed correctly in the first place, has the potential to be prone to ponding water.

Correct design and installation is key, because a roof needs to have adequate slope built in from the beginning, so that water can run off quickly and effectively. This is why professional and accredited commercial roofing companies in Manchester, can be essential to providing the correct installation of a roofing system.

The potential damage of ponding water can be eliminated with a bespoke roof design, installed to the proper standards. This needs to be combined with the use of high-quality roofing materials, and proactive maintenance, all from dependable roofing contractors.
