As a business owner, it’s crucial to maintain every part of your commercial building, and that includes your roof. The roof protects your business, employees, and assets from the elements. 

However, over time, roofs can develop issues that require repair or even replacement. In this comprehensive guide, we will explore the signs that indicate your commercial roof needs repair. By understanding these signs, you can take proactive measures to address any problems, prevent further damage, and ensure the longevity of your roof.


One of the most obvious signs that your commercial roof needs repair is leakage. If you notice water seeping through your roof during rainfall or detect wet spots on your ceiling or walls, it’s essential to address the issue promptly. Even if you can’t see visible signs of leaks, keep an eye out for secondary signs such as mouldy spots or a musty smell in your building. Water damage can lead to significant problems if left unattended, so it’s crucial to consult a professional roofing company to assess the situation and recommend suitable repair solutions.

Blisters and Bubbles

The appearance of bubbles or blisters on your commercial roof is another sign that should not be ignored. These bubbles are often caused by trapped moisture or inadequate roof application. While they may seem harmless at first, they can lead to more severe issues if left untreated. Blisters can allow water to seep through the roof, resulting in extensive damage to your building. To prevent further blistering and potential leaks, it’s crucial to address this problem promptly. Consult a roofing professional who can assess the situation and recommend the appropriate repair solutions.

Damaged Roof Membrane

Storms and strong winds can cause damage to your commercial roof membrane. If you notice uplifted sections, bald spots, or visible damage, it’s a clear indication that your roof needs attention. Minor damages can often be repaired, preventing further issues. However, if the damage is significant, or if the roof membrane is more than 25% uplifted, replacement may be necessary to ensure the structural integrity of your roof. Consulting a professional roofing company will help you determine the best course of action.

The Aging Factor

All roofs have a lifespan, and as they age, they become more susceptible to damage. If your commercial roof has reached its expected lifespan, it’s a strong indication that replacement may be necessary. Regular inspections and maintenance can help prolong the life of your roof, but eventually, age catches up. By having your roof inspected by a professional, you can determine whether it’s still in good condition or if replacement is the best option.

Shingle Damage

Shingles are a common roofing material for sloped commercial roofs. If your building has shingles, it’s essential to inspect them regularly for any signs of damage. Curling, cracking, splitting, or moss growth on shingles are indications of underlying issues. Additionally, patchy or bald spots on shingles require immediate attention. Ignoring shingle damage can lead to leaks and further damage to the roof. Contact a roofing professional to assess the damage and recommend appropriate repair solutions.

Flashing Wear and Tear

Flashing plays a vital role in commercial roof systems as it seals joints and protects against moisture. Damaged or deteriorating flashing can compromise the integrity of your roof, allowing water and debris to penetrate. Regularly check the condition of flashing around pipes, vents, and other structures on your roof. If you notice any signs of wear and tear or missing flashing, contact a professional roofer to replace it and ensure proper sealing.

Failed Downspouts: A Drainage Issue

Gutters and downspouts are integral components of your commercial roof’s drainage system. If they fail to carry water away from your roof, it can lead to pooling water and potential leaks. Clogged downspouts are a common problem caused by debris accumulation. Regularly inspect and clean your gutters and downspouts to ensure proper water flow. If you notice any issues with drainage, contact a roofing professional to assess and address the problem.

Damage Caused by Contractors: Act Swiftly

Contractors who access your roof for other purposes, such as HVAC repairs, can inadvertently cause damage. Even minor damage should not be taken lightly, as it can lead to more significant problems if left unattended. If you suspect that a contractor has caused damage to your commercial roof, it’s advisable to have it inspected by a professional roofer. They can assess the extent of the damage and recommend the necessary repairs to prevent further issues.

In conclusion, regularly inspecting your commercial roof for signs of damage is crucial for its longevity and the protection of your business. Addressing any issues promptly can save you money and prevent more extensive damage. If you notice any of the signs mentioned in this guide, it’s essential to consult a professional roofing company to assess the situation and recommend appropriate repair or replacement solutions. By taking proactive measures, you can ensure the integrity of your commercial roof and the safety of your business.
