Rooftop Units and Power Shutdowns in Grayson

A Grayson commercial roof repair contractor can only reflash a curb with the unit off. Grayson buildings are served by Grayson Rural Electric Cooperative or Kentucky Power, so the electric bill tells you who to call.

We line up the shutdown with your HVAC contractor before the curb is opened.

  • Power provider checked on the bill
  • Shutdown timed with HVAC service
  • Condensate lines rerouted off the roof

Grayson Commercial Roof Repair Around Rooftop Units

Rooftop units cause more repair calls here than any other part of the roof.

Most Common

Curb Flashing Pulled Loose

Unit vibration works curb flashing loose at the corners, and service traffic around the curb adds wear. Water gets behind the flashing and runs down inside the curb to the ceiling below.

Usually Means: Curb stripped and reflashed with matching membrane while the unit is off.

  • Condensate Drips

    Lines dripping onto the roof wear the surface beside the curb.

  • Tool Punctures

    Screws and dropped tools near units puncture the membrane.

  • Failed Curb Gaskets

    Old gaskets and loose screws between unit and curb let rain in.

  • Water Behind Curbs

    Large curbs with no cricket hold water on their upslope side.

Benefits of Repairing Your Roof

Curb repairs planned with the shutdown get done once, with the unit off and the flashing open.

Surface Saved

Rerouted condensate lines stop wear beside the curb.

Water Moves

Grayson Commercial Roof Repair Questions

Units, power and permits come up most.

Power and Units

Who supplies power for RTU shutdowns during roof repairs in Grayson?

Grayson buildings are served by Grayson Rural Electric Cooperative or Kentucky Power, and both list Carter County. Check the bill before planning the shutdown. Reflashing a curb, replacing curb gaskets and screws, and repairing condensate damage all need the unit off.

Can you reflash a curb with the unit running?

No. The flashing has to come off and go back up the curb, which means working inside the unit's footprint. A planned shutdown keeps the job to one visit.

How long is the unit off during curb reflashing?

Usually part of a day for a single curb. The unit is off while old flashing is stripped, the curb is cleaned and new membrane is run up and terminated. We set the time with your HVAC contractor so the shutdown falls when the space below can handle it.

Who disconnects the unit, the roofer or the HVAC company?

Your HVAC contractor shuts the unit down and restarts it. We work on the curb flashing, gaskets and membrane around the unit. Having both trades agree on the time keeps the unit off only as long as the repair needs.

Curbs

Why does my roof leak only when the unit runs?

Condensate lines dripping onto the roof or loose gaskets between unit and curb are the usual causes. Both get checked at the first visit.

What is a cricket and do I need one?

A small sloped build-up on the upslope side of a curb that splits water around it. Large curbs that hold water need one.

What damage do condensate lines cause on a roof?

A condensate line that drains onto the roof drips in the same spot for hours every day. The water wears the membrane surface, washes away granules on mod bit and keeps the area wet. We patch the worn spot and route the line to a drain so it stops dripping on the sheet.

Can a curb be repaired without replacing the unit?

Yes. Most curb leaks come from flashing, gaskets or screws, and all three are repaired with the unit in place. Replacing the unit itself is an HVAC decision. When a new unit is planned, we reflash the curb at the same time to avoid opening it twice.

Permits

Which office handles roof repairs in Grayson?

The Carter County sheet sends commercial construction to DHBC and lists a local inspector who covers Grayson. Ask which office handles curb replacement before a curb is rebuilt.

Do you repair other parts of the roof during curb work?

Yes. While the unit is off, we check and patch nearby seams, punctures from tools and the membrane where water ponds upslope of the curb. Doing it in one visit saves a second shutdown and a second trip onto the roof.

What does a curb repair cost?

It depends on the curb size, how much flashing has failed and whether wet insulation sits around the curb. Adding a cricket or rerouting a condensate line adds to it. We price it after the inspection, once the curb is opened up.
