Roofing costs for commercial vary widely, but regardless you know that it will be expensive. Thus, the state of your roof is something that you push to the back of your mind and never think about.

But, that roof is the only thing standing between your precious business and the outside elements.

Major problems with your roof could spell disaster, or even the end, for your business. You could lose expensive equipment and experience a lot of downtime due to an unexpected roofing failure.

Thus, it’s far better (and cheaper) to keep up with roofing maintenance. It’s also important to know the signs that your commercial roof needs to be replaced.


If you have water leaking down on your head when it rains, that’s an obvious sign that your roof needs some help. But, water leaks aren’t always that noticeable. This is especially true in commercial buildings where you can’t always easily see the underside of the roof.

Instead, you have to keep an eye out for secondary signs of leaks. Watch for water spots or signs of mold on the ceiling. If your building has an attic, go up on occasion to look for water damage.

Pay attention to how it smells while you’re there. If mold is beginning to grow in your roof you may notice a moldy smell long before visible damage appears.


Another thing to watch out for is blistering on the outside of your roof. This is also typically related to water damage.

Water trapped in the insulation will slowly eat up the inside of your roof. This process causes a release of gases which in turn cause blistering on the roof.

Shingle Damage:

If your commercial roof has shingles, you’ll want to inspect them on occasion. Take note if they are beginning to curl, crack, or split. Also, watch for bald or patchy spots. Moss growth can also be an indication that water is getting trapped inside.

Roof Membrane Damage:

A popular type of roofing for commercial buildings is a flat roof made from a roofing membrane. As with shingles, you should regularly inspect the membrane for signs of damage.

Keep an eye out for bald spots or lifting. These are both signs that the roof is no longer properly sealed and water can start being a problem.

You should also watch for open laps in the membrane. This can happen as the roofing adhesive ages and becomes less efficient. However, it can also happen on newer roofs if the insulation wasn’t installed correctly. Be sure to always be watching for it.
