Top Common Commercial Roof Problems in New Rochelle

Running a business comes with many responsibilities, and one that often gets overlooked is roof care. In New Rochelle, fluctuating weather, heavy storms, and aging buildings contribute to a variety of common commercial roof problems. These issues can disrupt operations, lead to expensive repairs, or even force temporary closures if not handled early.

At RJM Best Roofing Inc., we specialize in protecting commercial properties across the area. From flat roofs to multi-layered systems, we help business owners stay ahead of damage and prevent major structural issues. Let’s break down the most frequent concerns and how they relate to other common roof problems in New Rochelle.

Flat Roof Concerns in Commercial Buildings

Most commercial roofs are flat or low-sloped, which increases the risk of water-related problems. Ponding water, membrane cracking, and poor drainage are the biggest threats. Water that doesn’t drain properly can lead to leaks, structural sagging, and material breakdown.

Many businesses in New Rochelle deal with flat roof vulnerabilities every season. Our team is trained to detect early signs of wear and tear to help you avoid emergency repairs.

Damaged or Separated Flashing

Flashing protects the edges and seams of your roof, especially around vents, HVAC units, and skylights. On commercial roofs, these areas are more complex and prone to gaps as materials expand or shift. When flashing fails, moisture can get into insulation layers or ceilings, causing internal leaks and even mold growth.

Frequent inspection and re-sealing of flashing areas is a key part of preventing long-term damage in commercial systems.

Roof Membrane Blistering and Shrinkage

Single-ply or rubber roofing membranes are popular on commercial buildings, but they can develop bubbles or blisters due to trapped air or moisture. Over time, these weak spots split open, especially under UV exposure.

Membrane shrinkage can also pull seams and flashing apart, increasing the risk of water infiltration. These are all examples of common roof problems in New Rochelle that require professional attention before they escalate.

HVAC-Related Leaks and Penetrations

Most commercial rooftops support HVAC systems, vents, and ductwork. While these are essential, they also increase the risk of punctures and leaks. Improperly sealed penetrations or shifting equipment can damage the roofing material beneath, often going unnoticed until interior stains or mold appears.

At RJM Best Roofing Inc., we inspect around all units and accessories during routine roof checks to catch early signs of damage.
