Common Flat Roof Issues in Commercial Buildings in North Carolina

Flat roofs are a practical and popular choice for commercial buildings in North Carolina, offering a cost-effective solution with minimal space requirements. However, flat roofs come with their own set of challenges, especially when faced with North Carolina’s diverse weather conditions. In this blog, we’ll discuss the common flat roof issues that business owners in North Carolina may experience and provide solutions to help you maintain a durable, long-lasting roofing system.

 

Understanding Flat Roofs

Flat roofs, despite their name, aren’t entirely flat—they feature a slight incline to facilitate drainage. They are typically made from durable materials such as:

  • EPDM (Ethylene Propylene Diene Monomer): A synthetic rubber membrane known for its flexibility and durability.
  • TPO (Thermoplastic Polyolefin): A reflective single-ply membrane, ideal for energy efficiency, particularly during North Carolina’s hot summers.
  • Modified Bitumen: A robust mix of asphalt and rubber or plastic, reinforced with fiberglass for extra protection against water and weather.

These materials offer excellent performance, but North Carolina’s varied climate can put flat roofs under stress, leading to several common problems.

 

Leaks

Leaks are one of the most widespread flat roof issues in North Carolina. Intense storms, heavy rain, and wind are common in the state and can cause damage to seams, flashing, and other vulnerable areas, leading to leaks. If left untreated, even a small leak can lead to significant water damage, mold, and costly repairs.

Solution: Regular inspections are key. After storms or heavy rain, have a professional roofer inspect your roof for any signs of damage. Promptly repair any cracks or worn-out sealants to prevent water intrusion.

 

Ponding Water

Flat roofs are designed with a slight slope to direct water away, but ponding water—where water collects in pools—can become an issue if drainage systems are blocked or the roof becomes uneven. This can lead to leaks, algae growth, and even structural damage over time, particularly during North Carolina’s rainy seasons.

Solution: Keep your roof’s drainage system clear of debris, especially after storms or during the fall when leaves can clog gutters. If ponding is persistent, consult a professional to regrade or adjust the slope of your roof for better water flow.

 

Blisters and Bubbles

Blisters and bubbles form when moisture gets trapped under the roof’s surface. This problem is often caused by improper installation or underlying damage to the roofing material. North Carolina’s temperature swings between hot summers and cool winters can also exacerbate this issue by expanding and contracting the roofing material.

Solution: If you spot blisters or bubbles, call in a professional roofer to address the problem. Future occurrences can be minimized by ensuring proper ventilation and using high-quality materials during installation.

 

UV Rays

North Carolina’s hot and sunny summers can take a toll on flat roofs. Prolonged exposure to UV rays can degrade roofing materials over time, causing them to crack or lose their protective coating. This is especially true for roofs made from materials that are not UV-resistant.

Solution: Protect your roof by applying a UV-resistant coating. This can reflect harmful rays and help extend the lifespan of your roof by preventing wear and tear from constant sun exposure.

 

Pests

Birds, rodents, and insects are common pests in North Carolina and can cause significant damage to your flat roof. These animals can create holes, damage flashing, and lead to leaks, making it crucial to keep pests at bay.

Solution: Regularly inspect your roof for signs of pest activity, such as nests or droppings. Sealing entry points and installing pest deterrents can help prevent animals from damaging your roofing system.

 

Thermal Shock

North Carolina’s climate can experience wide temperature fluctuations, especially between day and night. These changes cause the roofing material to expand and contract, leading to cracks, splits, and other issues. This phenomenon, known as thermal shock, is one of the main contributors to flat roof wear in the region.

Solution: Proper insulation is essential for minimizing thermal shock. Insulating your flat roof can help regulate temperatures and reduce the expansion and contraction of the roofing materials, protecting your roof from damage.

 

Neglect

Regular maintenance is vital for extending the life of your flat roof, but neglect is one of the most common reasons for roof problems. Without routine inspections, small issues like leaks or cracks can grow into significant problems, leading to expensive repairs or even the need for a complete roof replacement.

Solution: Schedule regular roof inspections with a trusted roofing contractor. Regular maintenance allows for early detection of potential problems and helps prevent major damage down the road.

 

Poor or Improper Installation

Improper installation is another common issue that can lead to ongoing flat roof problems. If the roofing materials are not installed correctly, you may experience misaligned seams, poor drainage, or material failure. This is why choosing the right contractor is critical when installing a flat roof on your commercial building.

Solution: Ensure that your flat roof is installed by a reputable roofing contractor with experience in flat roof systems. Proper installation from the start will save you time and money by reducing the likelihood of future issues.
