Your Commercial Roof is Under Attack: How HVAC Equipment Threatens Your Most Valuable Asset
Commercial roofs represent one of the largest investments in any business property, yet they face constant threats from an unexpected source: the very HVAC equipment designed to keep buildings comfortable. HVAC units can affect your commercial roof through weight and placement of these units, creating a complex relationship that requires careful management to protect your investment.
The Hidden Dangers of Rooftop HVAC Systems
Industrial strength HVAC units are often installed on the roofs of commercial buildings and kept out of sight from the general public. While the importance of having a temperature controlled building may be great, these units can cause a variety of different roof problems and must be closely monitored.
The primary threats to your commercial roof include:
- Structural Overload: You don’t want your roof bearing too much weight, risking damage. When you add too much weight it can strain a roof’s structure causing it to sag or even collapse.
- Installation Damage: Industrial HVAC units are massive, heavy, and bulky, and if they are not installed properly, there could be costly consequences. It is not uncommon for some facility managers to have the same leak fixed over and over again, only to discover that the issue is really attributed to poor installation.
- Condensation Issues: One of the top HVAC-related roofing problems is leaking. HVAC units produce vaporized water which is ordinarily released into the air, though faulty units may cause this vapor to condense and pool at the base of the unit, leading to roof leaks, deterioration, and possible mold development.
The Foot Traffic Factor: When Maintenance Becomes Destructive
Regular HVAC maintenance is essential, but it comes with its own risks. While having your roof’s HVAC unit regularly inspected is important to lengthen its lifespan and detect leaks early, servicemen who are unaware of the correct way to walk on an industrial roof can end up causing damage. Excessive foot traffic can cause a strain on a commercial roof’s membrane and lead to cracks and leaks.
Roofing membranes are tough and durable when they’re new, but over time, they can wear and erode. They thin out in high-traffic areas, usually the result of maintenance workers or HVAC mechanics servicing rooftop equipment. This creates a vicious cycle where necessary maintenance actually accelerates roof deterioration.
Water Damage: The Silent Destroyer
Water infiltration from HVAC equipment poses one of the most serious threats to commercial roofs. Improperly sealed or damaged flashing around roof penetrations can result in water leakage. Water intrusion can lead to significant damage to the HVAC unit and its components, such as electrical systems, motors, controls and insulation. Moisture can cause corrosion, rust and short circuits, compromising the unit’s performance and potentially leading to costly repairs or even system failure.
The consequences extend beyond immediate damage. Water leakage due to inadequate flashing can lead to moisture buildup within the building’s structure. Excessive moisture can create an ideal environment for mold and mildew growth. Mold growth not only affects indoor air quality but can also spread to the HVAC unit, contaminating its components and ductwork.
Protecting Your Investment: Best Practices for HVAC and Roof Harmony
Protecting your commercial roof from HVAC-related damage requires a proactive approach that addresses both installation and ongoing maintenance concerns.
Professional Installation and Coordination
It is always recommended to have a roofing contractor oversee the installation process to protect the integrity of your roof. If you’re having a new HVAC unit installed, put your roofing contractor in contact with the equipment installer. They can discuss penetrations, appropriate flashing details, and the location of the unit to minimize its impact on the roof (e.g. slope, drainage, excessive weight, etc.).
Implementing Protective Measures
Smart facility management includes establishing protective protocols:
- Providing flag stands and flagging, guardrails, pathway marking tape, walkway pad, or an elevated walkway indicates where workers should traverse the roof. In the case of walkway mats/pad or elevated walkway, it also limits damage from foot traffic and restricts activity to designated areas.
- Minimize foot traffic on the roof to reduce the risk of damage to roofing materials and membranes. Establish designated walkways or access points and train personnel accessing the roof to avoid unnecessary damage.
- Limit and track who’s on the roof. Besides limiting who has roof access, keep track of it. Have people sign a log with the date and times they’re on the roof. People are more careful not to cause damage when they know they’ll be held accountable.
Regular Maintenance and Inspection
Maintain the HVAC unit’s rooftop equipment to prevent leaks caused by improper installation, condensation, or mechanical damage from equipment vibrations. Scheduling professional maintenance checkups is another important step. When you have an expert look over your roof and HVAC system every year, you can catch issues early on.
