Flat commercial roofs are more prone to leaks and damage than those with even the slightest slope.

No matter what material they’re made from, flat roofs allow water and debris to remain in one location on your commercial roof for a long period of time. This added weight can lead to weak spots in your roof.

The addition of even a slight slope to your flat commercial roof can help to alleviate many of the issues associated with entirely flat roofs. If you’d like to replace your flat commercial roof with a sloped one, or even just add a slight slope to your existing roof, get in touch with a commercial roofing contractor to discuss your options.

In this blog, we’ve put together a list of the most common problems with flat commercial roofs, so you know what to look out for.

Poor drainage to flat commercial roof

Inadequate drainage is the most frequent problem experienced with entirely flat commercial roofs. This is because the water often has nowhere to go, leading to ponding, which can cause major damage to your roof.

If your commercial property has a flat roof, it’s important to have the drains inspected by commercial roofing contractors regularly, to check that rainwater has a clear exit route.

Several layers of roofing installed

Harder to notice than bad drainage, this one is more common than you’d think. 

Sometimes, when commercial roofing contractors need to replace a flat commercial roof, they will just install the new roof over the top of the old one. 

This could happen multiple times over many years, leaving the materials underneath to rot, and ultimately compromising the whole structure.

Flat commercial roof not properly maintained

As we all know, prevention is always better than cure. Hiring commercial roofing contractors to carry out routine roof maintenance can help to avoid a host of problems with your flat commercial roof. These issues include a build-up of debris, leaks, and general wear and tear.

Poor installation of flat commercial roof

Flat commercial roofs, when properly installed, can last for decades. However, if they have not been installed by expert commercial roofing contractors, using quality materials, there is a huge potential for damage.

Whilst it may be tempting to go with the cheapest quote when replacing your flat commercial roof, it could end up costing you more in repairs and premature roof failure.
