Roof systems are built to endure harsh environmental conditions, but the foot traffic and service of rooftop unit contractors can introduce unique risks that jeopardize the roof’s integrity. From improper cleaning practices to mishandling of HVAC equipment, learn how issues can lead to premature roof failure and costly repairs.
Grease Contamination from Hood Vent Cleaning. For roofs equipped with grease ventilators, routine hood vent cleanings are essential for maintaining kitchen exhaust systems. However, improper cleaning practices can contaminate the roof membrane and drainage systems. Grease is highly caustic to all types of roofing materials, and if allowed to accumulate over time, it can cause significant damage. This contamination leads to premature roof failure, often resulting in leaks that can only be repaired through the replacement of affected sections. The combination of grease, moisture, and prolonged exposure accelerates the deterioration of the membrane, weakening its protective properties. Ensure your hood clean vendors are not using damaging chemicals.
Mechanical Contractor Hazards. Mechanical contractors, particularly those servicing rooftop units (RTUs), can inadvertently cause physical damage to the roof system. When working on RTUs, it’s common for fasteners, screws, or sharp tools to be misplaced or dropped. These objects can easily puncture or cut the roof membrane, especially if stepped on. Even small punctures can lead to serious leak activity, as water finds its way through compromised areas. Having contractors who provide before/after photos of service helps eliminate the chance of material being left behind to cause damage.
Another common issue is the removal and handling of HVAC unit panels. These heavy panels, when dropped onto the roof, can cause punctures or tears in the membrane. Furthermore, air filter media is often trimmed to size directly on the roof surface using straight blades. This practice can score or gouge the membrane, severely compromising the roof’s watertight integrity. Making sure you hire professional, diligent HVAC/R contractors is imperative.
Damage to Aging Roofs. Roof systems, particularly older ones such as PVC membranes, are more vulnerable to damage from third-party activity. As membranes age, they naturally degrade and become brittle. This makes them more prone to fracturing, especially under the weight of individuals walking on the roof. In these cases, even routine maintenance visits by contractors can exacerbate the roof’s degradation, causing it to tear away from itself and increasing the likelihood of leaks.
How to Prevent Third-Party Rooftop Damage:
Requiring Proper Documentation including before-and-after photos and detailed service reports, is essential for maintaining a safe and well-maintained roof. These records can provide valuable insights into the roof's condition before and after service performed for accountability of third-party contractors.
Installing Walk Pads is essential for establishing and safeguarding designated walking paths on rooftops. These durable materials not only provide secure footing for those accessing the roof but also shield the underlying membrane from potential damage. We strongly recommend the installation and upkeep of walk pads on all roofing systems. They clearly mark safe walking areas and add a critical layer of protection to vulnerable sections of the roof.
Preventing Unauthorized Access Of The Rooftop it should only be accessed by authorized personnel at all times. They are not suitable for employee breaks, smoking, or any other non-essential activities. Limiting access exclusively to qualified individuals is a crucial step in preserving the roof’s longevity and ensuring its optimal condition.
Third-party contractors can significantly impact the performance of a roof system. Proper care and awareness when working on or near the roof are crucial to preventing avoidable damage. By addressing these risks, building owners can extend the lifespan of their roof system and avoid costly repairs.
