HVAC Roof Problems can pose potential risks to your roof’s integrity.

Facility managers have a lot on their plates, and keeping the workers and employees who spend all day inside a commercial building comfortable is often a top priority. In most places, an HVAC system is installed on the roof of large buildings, but this carries with it several issues that a facility manager may have to deal with. While the benefits of having a cool building are numerous, HVAC roof problems can be exacerbated if you are unaware of the potential risks a faulty unit could pose.

Human Problems

While it is easy to blame all of your HVAC roof problems on the unit itself, there are some issues that are made worse by humans. Technicians who are not properly trained to locate concerns with the roof in addition to the unit may miss important signs that a well-trained tech would know signal the potential for a leak. If an HVAC technician is scheduled to stop by for routine maintenance, it may be a good idea to have a roof consultant join in on the inspection to see if there are any other underlying issues. Additionally, servicemen who are unaware of the right way to walk on an industrial roof can cause damage. If there is too much foot traffic on a roof’s membrane, it can begin to leak into your building. Make sure that anyone who gets on your roof knows to stay on walkways.

Condensation

When water collects on your building’s roof, it can cause the materials to break down faster and could lead to leaking, one of the top HVAC roof problems. The water that is vaporized in an HVAC unit has to escape into the air, but a faulty unit can cause it to pool. To solve this problem, it is important to have the right discharge system in place to keep excess condensation from collecting on the roof, either by proper drainage or through interior lines that keep moisture away from the roof.

Improper Installation

HVAC units are big, bulky and heavy, and if they aren’t installed correctly on an industrial roof, there could be serious consequences. Some facility managers find that they have to repair the same leaks over and over again, only to realize that the problem lies within how the unit was installed in the first place. Any time a unit is installed, it is wise to have a roofing contractor on hand to oversee the process.

HVAC roof problems can be frustrating, but they can also be easy to solve as long as facility managers are aware of the risks associated with these important systems.  Please feel free to contact us if you have any questions.
