How Your HVAC System Can Damage Your Roof

HVAC units installed on roofMost people prefer installing a rooftop air conditioner as opposed to a ground unit. This is probably because the former accumulates less yard debris and dust, which means that it won’t require cleaning as often. Besides, positioning your AC unit just out of earshot means less noise, as you don’t have to hear the buzz and rumble the system makes when turning on.

However, this type of unit is among the most prominent culprits for water-related damage on your roof. Explained below is how your roof-mounted AC unit can create problems.

Condensation causes mold growth and stains

The condensation emanating from your HVAC system needs to go somewhere. If this condensation is discharged on your roof, you are bound to experience localized ponding that enhances the risk of damage. Constant moisture also often attracts airborne dust and debris, which in turn causes mold, and in time, stains.

Incompetent technicians cause damage to the roofing material

Countless roofs get damaged due to hiring unskilled and careless technicians to install or maintain your HVAC unit. It is prudent to get services from a reliable HVAC company in West Valley to inspect your unit and prevent the development of leaks.

While the majority of technicians can easily isolate leaking evaporator coils or even replace fans, fins and motors, not every person is sufficiently trained to mount a unit and work from your roof safely.

Inappropriate flashing around the unit

This problem is frequently caused by errors committed during the installation of the HVAC system. All units are typically horizontal, meaning that they ought to have a metal cap that overlaps the roofing material. Failure to do this will lead to water seepage below the roofing material.

Most people have experienced the prevalent problem of water leaks, which is especially true during storms. While you would want to think that a leaking roof must be the result of a negligent roofer, sometimes the culprit is your HVAC system. It is, therefore, essential to ascertain that the technician you hire for either HVAC installation or repair is dully certified and has ample experience.
