common commercial roof problems

No roof can last forever. At some point, all commercial roofs will show signs of damage. As a property owner in Tennessee, you must know common flat roof problems. Catching minor issues can save you high replacement and repair costs.

At Miller Roofing and Renovations, we understand that your roof is an important investment in your building. We have listed 10 of the most common commercial roof problems to protect your investment from deterioration. Spotting and fixing these issues early can save your business from unnecessary downtime and structural damage. 

#1 Moisture Buildup & Roof Leaks

Leaks are a common issue for any roof. If moisture gets into your roofing system, it might cause mold growth or even roof collapse if the leak worsens. Excess moisture can damage the structural components and insulation of your roofing system. 

#2 Poor Installation

Improper installation is one of the common commercial roof problems that can impact the lifespan of your roof. Even a minor problem during installation can lead to bigger issues in the future or premature failure of your roof. If one layer of your roof was not installed properly, there is a chance that other parts were installed improperly, too. 

#3 Roof Ponding

Roof ponding is another common issue for commercial buildings. Common causes of roof ponding are clogged drains, structural irregularities, and foundational settling of the building, to name a few. To figure out the exact cause, consider asking an expert to conduct a roof inspection before starting repairs. 

#4 Blistering 

Roof blisters are formed when air or moisture gets stuck between the layers as the materials age and start to separate slightly. In the humid climate of Tenessee, this is another common concern for flat roofs. As the trapped air or moisture expands from heat, it pushes out the roofing layers, creating a raised blister. 

If the blister cracks open, it creates an entry point for water. When it rains, water can seep through the crack directly into the roof layers below. This repeated water intrusion can cause rot, mold growth, and structural damage if left unchecked.

The blisters can also weaken the overall roof structure. Large blisters make the roofing material more prone to tearing, puncturing, or completely detaching in areas. This accelerates the failure of the roof.

#5 Shrinkage

Roof membranes can shrink over time, leading to cracks and gaps. This is a common problem especially with EPDM (ethylene propylene diene monomer) roofs. Common causes of membrane shrinkage in commercial roofs are faulty design of the roof, incorrect installation, or poor quality manufacturing. 

#6 Hail Damage

Hail is another common issue in Tennessee, with Nashville and the surrounding areas of Tennessee witnessing 59 hail storms in 2023. Hail storms can dent and puncture your roof and affect the HVAC system and other rooftop equipment. 

#7 Faulty Flashing

Besides poor installation, the contraction and expansion of your roof over time can cause faulty flashing. Flashing is the metal strips that seal roof edges and protrusions. As roofing materials age, they can shrink and pull away from the flashing. Expanding and contracting from temperature changes can also loosen and crack the flashing. 

#8 Debris Buildup

The buildup of debris is another common commercial roof problem and can be caused by both natural and man-made reasons. Natural sources like trees, birds, and weather events can leave behind leaves, branches, nests, and dirt on the roof. Human activities like construction, rooftop equipment maintenance, or people walking on the roof can also lead to litter and miscellaneous items being left behind.

No matter the source, debris accumulation on a roof can clog drains and allow standing water to develop. It can also damage roofing materials over time as the debris rubs, scratches, or traps moisture against the roof surface.

 #9 Thermal Shock

Rapid changes in the temperature can cause thermal shock, leading to cracks and splits in the roof membrane. This is a common problem in Tennessee, where the temperature can fluctuate significantly. Using reflective coatings can help mitigate thermal shock.

#10 Animal and Insect Damage

Animals, pests, and insects can cause significant damage to commercial roofs, especially in Tennessee, where the climate is conducive to pest infestations. These little guests may nest, chew, burrow, or scratch into the roofing materials, creating an opening for moisture to seep into your roofing system. 

How to Avoid Common Commercial Roof Problems In Tennessee

To avoid these common commercial roof problems in Tenessee, it is important to prioritize regular inspections and maintenance. This includes scheduling annual inspections with a reputable commercial roofing company to identify and address potential issues before they become major problems. 

Additionally, property owners should ensure their roofing contractor or maintenance technician is certified to install and repair their roof and that they use the appropriate materials for their specific roof type and climate. Regular cleaning of drains, gutters, and downspouts can also help prevent debris buildup and ensure proper drainage.

Furthermore, property owners should consider implementing preventative measures, such as installing a roof coating or sealant to protect their roof from the elements. This helps prevent damage from wind, UV rays, and hail, and can also help to extend the life of the roof. 

Property owners should ensure their roof is ventilated properly to prevent moisture buildup and minimize the risk of mold growth. By taking these steps, property owners can help prevent common commercial roof problems, making sure that their roofs remain in good condition for years to come.
