Hawaiian Gardens Commercial Roofing from Downey, CA
Leaks around rooftop HVAC units in Hawaiian Gardens: our Downey crew separates roof curb flashing problems from equipment problems and prices the repair.
A leak near a rooftop unit in Hawaiian Gardens can come from two very different places: the roof flashing around the equipment curb, or the unit itself. Condensate lines, cracked drain pans, loose panels and failed duct seals all drip water that looks exactly like a roof leak inside. Repairing the curb flashing will not fix a unit that is leaking, and servicing the unit will not fix torn flashing. We check the roof side and tell you if we think the HVAC contractor needs to look at the equipment. Nearby, we also serve commercial properties in Artesia.
Hawaiian Gardens is a compact city crossed by Carson Street, Norwalk Boulevard, Pioneer Boulevard and I-605, and it borders Long Beach, Lakewood and Cypress. Its commercial buildings sit close together, so a service request should name the building and how to get on the roof. At the property, we check the equipment curb, the membrane and the details around it, then separate roofing work from equipment work and say what prep and permanent flashing are needed. That inspection also confirms the membrane type and flashing method before the repair is priced.
Find the leak at the curb
On the roof, we look at all four sides of the curb: the membrane flashing up the curb, the corners where splits are common, the top edge where the flashing meets the curb cap or unit, and the seams in the roof around it. We also note condensate lines, standing water around the unit and any obvious equipment leaks.
Our leak repair inspection compares what we see on the roof with where the water shows up inside. A stain near the curb does not prove the curb flashing failed. If the roof looks sound and the unit is dripping, we will say the equipment should be checked first.
Each unit gets its own look. One leaking curb does not mean every curb on the roof is bad.
We also check how the unit drains its condensate. A line that dumps water straight onto the membrane next to the curb keeps that spot wet all summer, wears the roof surface and can hide a real flashing leak. Routing it to a drain or adding a splash pad is cheap and often part of the fix.
Prepare the membrane around the curb
When the curb flashing has failed, we cut out the damaged membrane, clean and prepare the roof around it and repair any loose seams nearby. New flashing has to bond to sound membrane. Patching over a weak area just moves the leak.
A good roof repair at a curb also checks the insulation around it. Water that has been running down the curb for a while usually soaks the insulation next to it. We confirm and replace wet material, and make sure the new roof height still leaves enough flashing height on the curb.
If we open the roof and find more damage than expected, we stop, show you photos and agree on the added work. The curb is protected while you decide.
Coordinate with the HVAC contractor
Some curb repairs need the unit lifted, disconnected or supported so the flashing can go all the way up the curb. That is work for the HVAC contractor, not the roofer. We tell you exactly what we need from them and schedule our flashing after they have done it.
On a PVC roof, curb flashing is usually a sheet of PVC welded to the field membrane and run up the curb, with prefabricated or field-welded corners. If the curb is being raised or replaced, the flashing detail changes to fit the new curb, and the estimate should say which detail you are getting.
If the equipment work causes a delay, we leave the curb sealed temporarily so it sheds water. That is a stopgap, not the finished repair.
Old curbs are sometimes too short once the roof has been rebuilt or recovered a few times. If the flashing cannot reach a safe height above the finished roof, raising the curb is the real fix, and we will tell you that rather than stretch the flashing.
Plan the work area and sequence
We confirm roof access and where materials can be staged with the property manager, and coordinate timing with the HVAC contractor if the unit needs to be shut down or moved. Some units serve areas that cannot go without cooling for long, so we plan the work to keep downtime short.
When comparing estimates, look at what each one covers. A low number may reseal the existing flashing. A higher one may replace the flashing, the wet insulation and the corners. We will show you the difference. We also repair curb flashing in Lakewood, with each building inspected on its own.
We offer emergency leak response nights, weekends and holidays. A quick fix stops the water; we will list what is still needed for a permanent repair.
Photograph the curb before it is closed up
Before the new flashing is closed up, we photograph the cleaned roof surface, any replaced insulation and the flashing as it goes in. After the job, those layers are hidden, and the photos show what was done.
The photos go into your roof asset management file with the unit location marked. Equipment problems we flagged for the HVAC contractor stay on the list as open. Curbs we did not work on are noted, so no one assumes the whole roof was covered.
The right price fixes the actual leak: sound flashing on all four sides, dry insulation around the curb, and any equipment issue handed to the right contractor.
Commercial Roofing Questions
How do I know if the leak is the roof or the HVAC unit?
We inspect the curb flashing and the membrane around it, and look for signs the unit is dripping. If the roof looks sound and the equipment is leaking, we will tell you to have the HVAC contractor check it.
If the HVAC unit was just serviced, does that mean the curb flashing is fine?
No. Equipment service and roof flashing are separate. The curb flashing still needs its own inspection.
What should a curb flashing repair estimate include?
Removing damaged flashing, cleaning and preparing the roof around the curb, fixing nearby seams, replacing wet insulation and installing new flashing with sealed corners.
What if the curb or unit needs to be raised or replaced?
The HVAC contractor handles the equipment, and we install flashing to fit the new curb. The estimate shows which flashing detail goes with which curb.
What will I have after the repair?
Photos of the curb and flashing before and after, a record of what was replaced and a note of any equipment issues that were passed to the HVAC contractor.
