When the flashing around a rooftop HVAC unit pulls loose on a Moyock commercial building, rain can run straight down the curb and into the room below. Sometimes the curb itself is rotted, or the unit has shifted and torn the flashing. We repair rooftop equipment curbs for commercial buildings in Moyock and around Chesapeake, VA. We start by figuring out whether the problem is the roof flashing, the curb or the unit itself. If the unit needs to be moved or repaired, your HVAC contractor handles that part, and we coordinate with them so the curb gets fixed properly. You get photos and a clear explanation of the repair.
Moyock is the largest community in Currituck County, just south of the Virginia line along NC 168. Many people who live there commute into Hampton Roads on the Chesapeake Expressway, and its businesses range from small offices to retail and light industrial buildings. Before we inspect, the building contact gives us access and tells us which rooms are affected. We check the curb, the flashing and the wood and insulation underneath. Our recommendation covers what needs protecting and any testing needed before the permanent repair.
Is it the curb or the unit?
Rooftop units have their own seals and panels, separate from the roof flashing around the curb. A leak from either one can show up as water in the room below. We inspect the roof flashing and note any damage we find. If the unit itself looks like the problem, such as a failed panel gasket or clogged condensate pan, your HVAC contractor should check it. A roof patch won't fix a leaking unit, and a new unit won't fix bad curb flashing.
Our equipment curb and support repairs in Moyock follow what we find. Buildings in Camden get their own inspection. If the unit needs to be lifted or disconnected so we can reach the curb, we schedule that with your HVAC contractor before opening the roof. We explain which repairs are ours and which belong to another trade. Photos show the damaged flashing and the roof around it that will stay. If we can't tell whether the unit is part of the problem, we say so.
Rotted curbs and wet insulation
A curb has to be solid to hold flashing. If the wood is rotted or the curb has shifted, new flashing won't stay attached. We check the curb and the insulation around it. Sometimes we can't tell how bad the damage is until we remove the old flashing. Damaged wood or insulation is replaced, and the new curb has to support the unit and leave room for proper flashing height. If there's a question about whether the roof structure can support the unit, we'll recommend an engineer.
When insulation and cover board around a curb need replacing, we confirm what's wet first. Buildings across Chesapeake's commercial areas get the same attention. The building manager confirms access and which areas need protection. A taller or rebuilt curb can change the flashing size, so we measure after the curb is repaired, not from photos. Sound material stays in place. If we find more damage once the roof is open, we document it and explain the added work.
Scheduling around your HVAC contractor
Your HVAC contractor may need to disconnect, lift or service the unit before we can rebuild the curb. They're responsible for the equipment, and we're responsible for the roof around it. If the unit is being replaced or moved, the new arrangement can change the curb size or position, so we plan around that. We coordinate access so the new curb flashing doesn't get damaged when the unit goes back on. If the unit is waiting on repairs, that can limit how much roof work we can finish in one visit.
Our penetration and curb flashing repairs follow that plan. We check the membrane around the curb before choosing a repair method. Old sealants and weathered membrane may need to be removed so the new flashing bonds. Materials are matched to your roof type, not a generic product. On some roofs, we test a small area first. Those results apply only to the spot tested. We install the new flashing once the curb, the roof and the HVAC work are all ready.
Protecting the curb while parts are on order
Opening up a curb can leave the building exposed if the unit or parts aren't ready. The building manager tells us which rooms below need protection. We set up temporary protection that ties into the existing roof and clearly mark it as temporary. New flashing parts and HVAC work need to be scheduled before we open a larger area. If ceilings or electrical equipment got wet, your maintenance staff or an electrician should check them.
Our emergency roof repair crews can put temporary protection on a Moyock curb right away. If we're waiting on parts or the HVAC contractor, we explain what needs to happen before the permanent repair continues. Temporary materials are chosen to fit the curb and the weather expected. We keep water draining away from the curb where possible. If water shows up somewhere new, we check it against the temporary setup. We plan how materials will be carried across the roof so we don't damage it on the way.
After the curb is rebuilt
When the curb is rebuilt, we check every seam and edge of the new flashing. We confirm the curb is solid and the flashing transitions properly to the surrounding roof. If HVAC work is still pending, we note it separately. Future service crews should use paths that won't damage the new flashing. If the roof around the curb gets disturbed later, we inspect it fresh. Photos show the rebuilt curb, the unit and the roof around it.
Our roof condition reports for Moyock buildings show exactly what we repaired. For office buildings, the building manager confirms access. Interior contractors can move ahead once the roof is done, but they decide when the room is ready. If a new leak appears, tell us when it started and where water showed up first. You can report leaks nights and weekends with the location, and we'll confirm timing after reviewing the conditions and access. Our repair is always based on the damage we actually found at the curb and the support it needed.
Commercial Roofing Questions
Will replacing the HVAC unit fix a Moyock curb leak?
Not necessarily. The unit and the roof flashing around its curb are separate. We inspect both and repair the one that's actually leaking.
How do you size the new curb flashing?
We measure after any damaged curb wood is replaced, since a rebuilt or taller curb changes the flashing size. Changes to the unit can affect it too.
Who moves the HVAC unit during curb repairs?
Your HVAC contractor. They handle the equipment, and we coordinate so the curb can be rebuilt and flashed while the unit is off.
How do you protect the curb while waiting on parts?
We install a temporary seal that ties into the surrounding roof, keep water draining away and explain what's needed before the permanent repair.
What should HVAC crews know after the curb is repaired?
Where the new flashing is and how to avoid damaging it. If the roof around the curb gets disturbed, we'll inspect it fresh.
