7 Signs It’s Time to Replace Your Commercial Roof


When it comes to maintaining your commercial building, one of the most critical aspects is ensuring the integrity of your roof. A well-maintained roof not only protects your assets but also provides a safe environment for your employees and customers. However, like any other structure, commercial roofs have a lifespan and may require replacement after a certain period. In this article, we will discuss seven signs that indicate it’s time to consider a commercial roof replacement.

1. Age of the Roof

Commercial roofs are designed to last for a specific period, typically between 20 to 30 years, depending on the material used. As the roof ages, it becomes more susceptible to wear and tear, making it essential to consider the age of your roof when assessing its condition. If your commercial building roof is approaching or has exceeded its recommended lifespan, it may be time to think about commercial roof replacement.

2. Water Leaks

Water leaks are one of the most common signs of roof damage in a commercial building. If you notice water stains on the ceiling, mold growth, or musty odors inside the building, it may indicate a leaky roof. J.R. Swigart Roofing recommends addressing water leaks promptly to prevent further damage to the structure and considering commercial reroofing.

3. Sagging or Uneven Roof Areas

Sagging or uneven areas on your commercial roof can indicate structural issues such as water pooling, improper installation, or weakened roof supports. These issues can compromise the integrity of the roof and pose a safety risk to your building occupants. It is crucial to address sagging or uneven roof areas immediately to avoid collapses or further damage.

Sign of Sagging Roof:

Potential Signs of Sagging Roof
– Visible dips in the roof
– Uneven or sloping roof surface
– Cracks in interior walls

4. Visible Damage

Inspect your commercial roof regularly for visible damage such as cracks, blistering, peeling, or missing shingles. These damages can weaken the roof’s structure and lead to more severe problems if left unattended. Timely repairs or replacement can help prevent extensive damage and protect your commercial building.


5. Increased Energy Bills

If you notice a sudden increase in your energy bills, it could be a sign of a faulty commercial roof. A compromised roof can result in poor insulation, causing your heating and cooling systems to work harder and consume more energy. Monitoring your energy bills can help you detect potential issues with your roof and consider commercial roof replacement to improve energy efficiency.

6. Deteriorating Roofing Materials

Pay attention to the condition of your roofing materials such as shingles, membranes, or metal sheets. Deteriorating materials are more prone to leaks, cracks, and other damage, compromising the effectiveness of your roof. J.R. Swigart Roofing suggests replacing deteriorating materials to ensure a durable and reliable commercial roof.

Common Deteriorating Roofing Materials:

Deteriorating Roofing Materials
– Cracked shingles
– Warped membranes
– Rusted metal sheets

7. Roofing Problems After Severe Weather

Severe weather events like storms, hail, or high winds can cause significant damage to a commercial roof. If you observe signs of damage such as torn or missing shingles, dents, or debris on the roof after a severe weather event, it may be time to schedule a professional inspection. Prompt action following severe weather can help assess the extent of damage and determine if a commercial roof replacement is necessary.

In conclusion, recognizing the signs indicating the need for commercial roof replacement is crucial to maintaining a safe and secure environment for your commercial building. Regular inspections, prompt repairs, and timely replacement can help prevent costly damages and ensure the longevity of your roof. If you notice any of the signs mentioned above, consider contacting J.R. Swigart Roofing for professional commercial reroofing services.
