AC Curb & Roof Penetration Repair in Orlando, FL


Some of the most leak-prone areas of a commercial roof are not in the main roofing surface—they are around the equipment, pipes, vents, and other components that pass through it.


Edgar Quintin Roofing provides roofing repairs around AC curbs and other roof penetrations throughout Orlando and surrounding Central Florida areas. We focus on the roofing, flashing, membrane, and waterproofing surrounding these areas to help stop water intrusion and protect the building below.

Why AC Curbs Can Become a Source of Roof Leaks

Many commercial buildings have HVAC equipment installed on raised roof curbs. These curbs create a transition between the roofing system and the mechanical equipment above it.


Because the roof membrane must terminate, wrap, or flash around the curb, these areas require careful waterproofing. Over time, sealants can deteriorate, flashing can loosen, membranes can separate, and previous repairs can begin to fail.


Heavy Florida rain can quickly expose a weakness around an AC curb.


Possible signs of a problem include water stains beneath rooftop equipment, recurring leaks during heavy rain, deteriorated sealant, loose flashing, or visible membrane damage around the curb.

Repairing Other Roof Penetrations

AC units are only one type of penetration found on commercial roofs. Water can also enter around:

  • Plumbing vents
  • Exhaust vents
  • Pipes
  • Electrical penetrations
  • Conduit
  • Roof drains
  • Skylight curbs
  • Equipment supports
  • Ventilation equipment
  • Other rooftop fixtures


Every opening through a roofing system creates another area that must remain properly flashed and sealed.

Fixing the Roof Around the Equipment

When investigating a leak around rooftop equipment, it is important to determine whether the water is entering through the roofing system, the flashing, the curb, or another nearby component.


Our roofing work can include repairing membrane around a curb, correcting flashing problems, addressing damaged roofing materials, resealing appropriate transitions, and repairing surrounding areas that have become vulnerable to water intrusion.


For HVAC equipment, our service is focused specifically on the roofing and waterproofing around the unit rather than repairing the mechanical AC system itself.

Protecting Commercial Roof Penetrations in Central Florida

Orlando's heat, UV exposure, heavy rain, and severe storms can gradually deteriorate sealants and other materials surrounding roof penetrations. These areas should be checked periodically, particularly after rooftop equipment has been installed, replaced, or serviced.


Something as simple as moving or replacing an AC unit can disturb an existing curb or surrounding roofing materials if the area is not properly addressed afterward.


If you have a leak around an AC unit, vent, pipe, or other rooftop penetration, contact Edgar Quintin Roofing. We can inspect the surrounding roofing system, identify potential water-entry points, and provide the appropriate roofing repair for your Orlando-area commercial property.
