3 Commercial Roofing Red Flags to Keep an Eye Out For

Thanks to their low slope, flat roofs are more leak-prone than sloped residential roofing systems. Remember: water ponds on flat surfaces. Aside from leaks and ceiling stains, what are the roofing red flags you need to keep an eye out for? Wortham Bros, your trusted McKinney roofing company, lists them in this blog post.  

Ponding Water 

The term flat roof is a bit of a misnomer: it’s slightly elevated to allow water to flow to the drains. If there’s water ponding on top of the flat roof, check if the drains are clogged. Ponding water is a cause for concern because flat roofs aren’t designed to handle additional weight loads for long periods of time. Don’t underestimate how much a pool of water can weigh—ponding water 20 by 20 feet and only an inch deep weighs 2,000 pounds. Additionally, according to the National Roofing Contractors Association, standing water shouldn’t be left unattended for more than two days. Otherwise, the pooling water might seep into the roof’s underlayers.

Vegetation 

Vegetation may start to grow on the surface of the flat roof if rainwater deposits enough dirt on top of its surface. Any vegetation growing on your roof is a problem because its roots can penetrate the roof’s surface, leaving it vulnerable to moisture damage. 

Cracks

Large cracks are usually a sign your roof is nearing the end of its lifespan. If you’re not sure if you need a roof replacement, it’s best to consult a commercial roofing contractor. 

Here’s a tip: To keep track of your roof’s lifespan, contractors recommend keeping a roofing file containing important details such as the date of the roof installation and the maintenance records.
