Commercial roofs are a lot different from residential roofs as they are larger in area. Like residential roofs, Commercial roofs too need regular maintenance and inspection. Your commercial roof indicates the quality of your business. As many people work inside the property, one must ensure that the commercial roof is of prime quality all the time. Weather elements and the wear and tear of the roof often require one to get roof repairs done. 

An extreme thunderstorm of heavy wind may damage the roof to an extent where you might have to replace it. Both roof repair and replacement for a commercial setup can be very costly and expensive. Periodic roof inspection and maintenance helps to save money and avoid roof issues.


Some of the common roof issues identified by commercial roofers are listed here. Monitoring these issues determine whether your commercial roof needs a repair or replacement:

1. Roof Age

Every roof, be it residential or commercial, comes with a life span or an age. The age of your commercial roof can range from 15 to 30 years. Yet, it also depends on the materials used, weather elements, and maintenance of the roof. Keeping up the roof clean and tidy with regular maintenance in place can make the roof last longer. 


Most of the time, repairs performed by professionals help to keep the roof. Sometimes, with roof age and extreme weather, roof replacement is the only option. Getting the roof inspected is the best way to assess if the roof can sustain the rains and storms or not. Based on the experts' advice, one must consider commercial roof replacement if the roof is nearing its age.

2. Damage to Roof Membrane

Commercial roofs have a flat surface or a low slope made with layers of single-ply material coverings. These layerings include insulation, decking, and protective layering. Commercial roofs accommodate industrial pipes, generators, and commercial HVAC systems. When equipment maintenance takes place, there would be punctures in the roofing system and roof membrane. One must ensure to watch out for these damages to prevent roofing failure. To avoid colossal replacement or repair costs, conduct regular inspections. One must ensure to inspect the roof before the repair and maintenance of the roof. 

3. Bubbling on the roof

Bubbling of the roof occurs due to loss of adhesion of the roof. Improper roof installation and ventilation lead to bubble formation in the roofs. When moisture gets trapped under the roofing materials or membrane, the water evaporates. This results in bubbles and blisters on the roof. These bubbles allow the water to seep through the roof and cause damage to the building. One must contact the roof inspector to get the bubbling issues sorted. Before the bubbling spreads, it's best to get repairs done as soon as one notices the formation of bubbles or blisters. Tiny bubbles and blisters may not be a serious concern. But it is worth getting the commercial roof repairs done without delay to avoid a roof replacement.

4. Check Flashings

Flashings are the joints between structures like chimneys, vents, skylight, and the roof. The primary function of flashing is to divert water towards gutters and away from various spots of the roof. Flashing also protects roofing materials from harsh weather and moisture. With shoddy repair works, weather elements, and faulty installations, the flashing gets worn out. When the flashing becomes damaged, it stops to shed water away from the protrusion. This leads to water leaks into your building. To detect the origin of the leaks, a complete inspection of flashing is necessary. Whether the roof needs a repair or replacement depends on the extent of water damage. 

5. Insulation

The insulation deck below the roof helps to keep your building warm in cold seasons and vice versa. But in case you see a rise in your energy bills, it indicates that your roof is asking for a repair or replacement. Poor insulation with improper sealing makes the heat and cool air escape the indoors. When moisture gets trapped in insulation, you will notice mold and mildew growth. This is again a sign that your roof needs a repair. 

6. Clogged Drains

Twigs and leaves that fall off with winds and storms form debris over some time. If this debris is not cleaned out from the roof, they clog the drains of your commercial property. The water accumulates in the roof that shakes up the roof membrane. Having any stand-still water on the roof deteriorates the roof and its insulation system. This shortens the roof's life and, if ignored, can result in the failure of the roofing system. It is essential to clean the Clogged drains from time to time, especially after rains and storms. 

7. Leaks & Moisture

If you notice any water spots in the corner of your commercial setup, there are chances of roof leaks. Any such defects and weakening of interior walls is an indicator of roof leakages. Due to heavy rains and winds, there are potential holes in the roof and attics. This leads to leakages in the interior walls. The moisture stains the walls, and the interior walls may have cracks and peeling. It is always better to get the roof inspected to know whether you should go for roof repair or roof replacement. 

8. Sagging Roof

Heavy winds, snow, hail, and rainfall will cause damage to the roofing materials. This results in sagging of the roof as the roofing materials start to dip down. When the roofline begins to drift off its place, the sheathing and joints of the roof get damaged. Any kind of dropping in the roofline should make an alert to get the roof inspection done. Commercial roofing contractors can identify and fix the sagging roof issues in an efficient way. But if the extent of roof sagging is beyond repair, then one can opt for roof replacement. 

Wrapping Up

Commercial roofs last longer and can stay up for more than 30 years if maintained well. A few repairs after harsh and extreme weather elements keep your roof structure in place. Never ignore common roofing issues like mold formation, moisture, debris, or musty odors. All these issues are a clear indicator that your roof requires repair. 


In case of extreme damage, your roofing contractor may advise on roof replacement. Keeping all the considerations, one must discuss all possibilities with professional roofers. Based on their suggestion, one can choose to go for Roof repair and replacement.
