Commercial roofs are built to endure harsh environmental elements, but they are still susceptible to damage. Being aware of the most common causes of commercial roofing issues can help property owners take proactive steps to protect their investment. Below, our experts outline the top reasons for damage and how to prevent costly repairs down the line.

1. Weather Extremes
Middlebury, CT experiences a wide range of weather conditions, including heavy rain, strong winds, hail, and fluctuating temperatures. Each of these can wreak havoc on commercial roofs. Wind can lift and tear materials, rain can lead to ponding and leaks, and hail may cause dents or cracks. Temperature shifts can cause roofing materials to expand and contract, eventually leading to brittleness or warping.
2. Improper Installation
Poor installation is one of the most preventable causes of roofing failure. If the roof was not aligned correctly, sealed properly, or installed using subpar materials, it becomes vulnerable from the start. Hiring a certified roofing contractor who follows manufacturer specifications and industry best practices is essential to ensure long-term performance.
3. Lack of Maintenance
Skipping regular maintenance is a costly oversight. Without routine inspections, minor issues like debris buildup or clogged drains can go unnoticed and escalate into significant problems. Regular cleaning, prompt repairs, and seasonal checkups are key to extending the life of your commercial roof.
4. Punctures and Tears
Foot traffic, falling branches, or dropped tools can create punctures and tears in roofing membranes. Once compromised, these areas are prone to water infiltration and further degradation. Protecting vulnerable sections and addressing minor damage quickly can help avoid bigger issues.
5. Poor Drainage
Commercial flat roofs must have adequate drainage systems to avoid water pooling. Standing water adds weight and can eventually seep through the roof, weakening the structure. Gutters, downspouts, and internal drains should be inspected and cleared routinely to ensure water flows away from the roof efficiently.
6. Biological Growth
In humid or shaded spots, roofs can develop moss, algae, and mold. While they may seem harmless at first, these organisms trap moisture and deteriorate roofing materials over time. Regular cleaning and preventative treatments can combat growth and help preserve your roof’s integrity.
7. Age and General Wear
Even the best-maintained roofs have a lifespan. Over time, exposure to the elements causes gradual wear and tear, reducing effectiveness. Signs of aging—like cracked materials, leaks, and insulation problems—signal that it may be time for repairs or a full replacement. Professional inspections help determine the right course of action.
