7 Commercial Roof Issues to Avoid

As commercial roofing professionals, we are often asked to respond to roofing emergencies after something catastrophic takes place. However, most roofing issues are less devastating and can be fixed if caught in time. Here are seven of the most common roofing issues that we see at commercial buildings.

1. Poor Installation and Workmanship: When your commercial roof is installed improperly, leaks, shrinkage of roofing materials, and even premature failure of the entire roofing system may be in your future. This often happens when the roofing contractor lacks experience or cuts corners to save on costs. The key to avoiding this problem is to thoroughly vet your roofing contractor. Look for certifications, ask for references, and ensure they have a solid track record with commercial roofing projects.
2. Roof Leaks: Roof leaks and water damage remain among the biggest problems that commercial properties face. The insidious thing about leaks is that water can travel far from the original breach before showing signs inside the building. By then, the damage might have already become extensive, potentially affecting your property’s structure. At the first sign of a leak, even something as seemingly inconsequential as a water stain on the ceiling tiles, immediate action is required to track down the source and repair it before the issue escalates.
3. Standing Water or Ponding: Ponding water is a frequent issue with flat or low-slope roofs on commercial buildings. It usually occurs when the drainage system is inadequate or becomes clogged, preventing water from being efficiently removed from the roof’s surface. The danger with standing water is multifaceted, with leaks, roof degradation, and structural integrity concerns being the most pressing issues.
4. Weather-Related Damage: Commercial roofs are particularly vulnerable to weather-related damage, especially in a state like Florida. To protect your investment, it’s important to have a roof designed to withstand local weather conditions. After any significant weather event, have a professional look for signs of damage on your roof. Early detection of issues like loose materials or water infiltration can prevent costly repairs or replacements down the line.
5. Blistering, Cracking, and Surface Erosion: Blistering and cracking on the roof’s surface are often signs of aging, but they can also indicate deeper issues that are accelerating the eventual degradation of your roof. Surface erosion, particularly on asphalt roofs, can occur due to weather exposure, leading to the loss of granules and weakening of the roof’s protective layer. Regular roof inspections can catch these problems early, as maintaining adequate drainage and keeping your roof free from debris can prevent water accumulation that leads to blistering and cracking. Repairing small areas of damage promptly can prevent larger, more expensive issues from developing.
6. Flashing Issues: Flashing is designed to seal and protect the perimeter and protrusions such as vents, chimneys, and skylights on your roof. However, it can become a major concern if improperly installed, corroded, or damaged. Given that flashing is one of the most important parts of preventing water from entering your building, inspect these areas regularly for signs of wear or damage. A professional should address any gaps, rust, or detachment promptly. If you’re installing a new roof, choosing a reputable contractor who uses high-quality materials for flashing can save you from future headaches.
7. Damage from Foot Traffic: Commercial roofs often accommodate more foot traffic due to maintenance, installation of equipment like HVAC units, or even access for employees in some cases. This traffic can lead to punctures, especially in single-ply roofing systems, and the degradation of roofing materials over time. Educating staff and contractors about the importance of minimizing foot traffic and identifying safer pathways can also help preserve your roof’s integrity.
