Grocery store roof repair in Berkeley, CA: leaking refrigeration curbs, wet insulation and condensation problems fixed with the store open.
Property Types We Roof | Berkeley, CA
A grocery store roof carries a lot of equipment: refrigeration condensers, HVAC units, exhaust fans and the lines that run between them. Each one sits on a curb or support that has to be flashed into the roof. On a grocery store in Berkeley, CA, a loose curb flashing can drip onto a produce case or a stockroom shelf, and the wet insulation around it can keep leaking long after the flashing is patched. Grocery stores also have plenty of cold surfaces inside, so not every drip is a roof leak. Sorting that out early saves money, because a roofer cannot fix a condensation problem and a refrigeration tech cannot fix torn flashing.
We start on the roof at the curb nearest the leak and check the flashing, the curb framing, line penetrations, nearby seams and drains. If water is coming in now, we can install temporary protection the same day, including nights, weekends and holidays. Your store manager arranges access and tells us what is stocked below. Refrigeration lines and units stay with your refrigeration contractor, and wet electrical goes to an electrician.
Curb flashing can look fine while the wood behind it has rotted. Our rooftop curb and equipment support repair opens the flashing to check the framing. If a unit has to be shut down or lifted to reach the curb, your refrigeration or HVAC contractor does that, on a schedule that keeps product safe. Rotted wood gets replaced and short curbs get raised. New sealant along the top edge of a rotten curb will not hold. We also check that condensate lines drain onto the roof or into a drain properly, since water from a misrouted line can sit against a curb all year.
Water inside a grocery store can come from more than the roof. Condensation on cold case piping, a clogged condensate line or a gap in the cooler walls can all drip in the same aisle. We check the roof above the drip and compare it with when the water appears; leaks that show up only in rain usually point to the roof. If the evidence points to refrigeration or the building envelope, we say so and pass it to the right specialist. Any test cuts we make are sealed the same day. That keeps everyone from paying for the wrong repair.
Wet insulation around a curb or line penetration has to come out. Our insulation and cover board replacement removes it back to dry material, confirmed with small core cuts, and installs new boards. Any deck damage goes to an engineer. New insulation can raise the roof surface around the curb, so we check that the curb is still tall enough and that water drains away from it. That work happens before the new membrane closes off access to the curb.
The flashing itself depends on the roof. Our penetration and curb flashing work uses heat-welded flashing on PVC or TPO, and compatible bitumen products on modified or built-up roofs. If the membrane around the curb is dirty with grease or too brittle to bond to, we cut back to clean material. If the refrigeration contractor needs to service the unit first, the curb gets a secure temporary seal until they are done. We also look for grease from kitchen exhaust on stores with a deli or bakery, since grease breaks down some membranes and has to be cleaned or the area replaced.
Grocery stores stay open, and food has to stay protected. Our occupied building reroofing plan shows which aisles, cases and stockrooms sit under each day's work, when deliveries and crane lifts happen and how debris comes down. Your store team decides which product gets covered or moved and when aisles close. Your refrigeration contractor decides what equipment can be shut down and for how long. We keep lifts away from customer entrances and schedule noisy work early.
If the wet insulation turns out to run over another department, we stop, show your manager what we found, and agree on protection before cutting further. If the refrigeration or envelope specialist needs to finish their part before we can close the roof, we leave a secure temporary seal and note it. Every opening is sealed before the crew leaves, and the daily notes say what is permanent and what is temporary. If a delivery or a refrigeration service call changes the plan, we adjust the schedule the same day.
Grocery roofs in Berkeley and Oakland cover sales floors, coolers, receiving areas and equipment zones, each with different needs. For stores near downtown Berkeley, we schedule visits around deliveries and store hours. It helps to know where the drips are, when they show up, and whether you have refrigeration or roof drawings. Past repair invoices also tell us which curbs have been patched before.
In West Berkeley and Emeryville, grocery stores sit near busy commercial corridors and older industrial buildings. Berkeley's long dry season followed by heavy winter rain dries out sealants and then tests them all at once. Refrigeration equipment adds its own wear, with vibration and condensate water on the roof. We inspect every curb and penetration on the roof and write the repair plan for your store, not one copied from another location. Curbs that have been patched more than once usually get rebuilt rather than patched again.
Cold storage roofs face the same condensation questions on a larger scale. For a grocery store, the closeout package includes photos of each rebuilt curb, the new flashing and any replaced insulation, plus a roof plan marking them. Roofing work is kept clearly separate from refrigeration work, so each contractor knows what they own, and anything still open for another specialist is listed.
Restaurant roofs share the grease and equipment issues, but each building's hidden damage is different. For your store, the roof plan gives facilities staff a clear reference. If a drip shows up later, they can check whether it is under a curb we repaired, note whether it was raining, and send us photos. That helps us tell a roof leak from a refrigeration problem quickly.
Tell us where the drips show up and when, and send any equipment drawings you have. We will inspect the curbs and send a photo report with a clear repair plan.
