5 Common Signs of Roof Damage

Think it might be time for a new commercial roof? We’ve got your back. Your commercial property’s roof is like its superhero cape, protecting your assets, employees, and customers from the elements. But over time, it can take a beating from Mother Nature. Ignoring those signs of roof trouble can lead to pricey repairs and a headache for your business. In this post, we’ll take a look at some telltale signs your commercial roof needs some TLC and why you should act fast.

1) Water Stains 

When it comes to spotting roof issues, water stains are hard to miss. If you spot water stains on your ceiling or walls, it’s a clear sign that your roof’s defenses are down. Leaks can be caused by all sorts of things, like damaged roofing materials, worn-out flashing, or clogged drains. Fixing leaks pronto is the name of the game to keep your building’s interior dry and mold-free.

2) Damaged Roof Materials 

Give your roof a once-over to spot any missing or damaged roofing materials, whether it’s shingles, tiles, or membrane sections. Strong winds, hail, and heavy rain can do a number on these materials. When they’re missing or damaged, they leave your roof’s insides exposed to the elements, inviting more damage. Don’t wait—replace or repair those materials ASAP to keep your roof in tip-top shape.

3) Standing Water 

Water that hangs around on your roof’s surface after a rainstorm is a red flag. It could mean your drainage system is wonky or your roof’s structure is sagging. Pooled water can speed up roof wear and tear and cause leaks, so it’s crucial to find and fix drainage problems quickly. Make sure your roof’s drainage system is doing its job, directing water away from your building.

4) Blisters and Bubbles 

Commercial roofs go through temperature swings that can make roofing materials expand and contract. Over time, this can lead to unsightly blisters and bubbles on the surface. These bubbles hint at trapped moisture beneath the roofing material, making it less effective. If you ignore them, things can get even worse. Call in a pro roofing contractor to assess the situation and recommend the right repairs.

5) Sagging Roof Structure 

A saggy or misshapen roof structure is a big warning sign that your roof needs help, and fast. It can happen for all sorts of reasons, like water damage, weak structural support, or too much weight up top. A sagging roof isn’t just a safety concern—it also increases the risk of more damage to your roof materials. If you spot any structural weirdness, don’t hesitate to bring in a structural engineer or roofing expert for a thorough check-up and the necessary fixes.
