Shopping center roof repair in Berkeley, CA: leaking demising walls, wall flashing, drains and wet insulation fixed across multiple tenants.
Property Types We Roof | Berkeley, CA
Shopping centers often have raised walls on the roof where one tenant space ends and the next begins, plus taller walls where a larger anchor store meets the inline shops. Each wall has flashing that runs up the side and a cap or counterflashing on top. On a shopping center in Berkeley, CA, that flashing pulls away over time, the wood behind it rots, and water runs into one tenant's ceiling, sometimes the tenant next door to where it actually entered. Two tenants, one leak and a lot of phone calls. Sorting out which wall is actually leaking saves both tenants, and you, from paying for repairs in the wrong place.
Before the visit, tell us which tenants have reported leaks and send any roof drawings. On the roof, we check each wall flashing and cap, nearby seams, curbs and drains. A rooftop unit belonging to one tenant can leak into the neighbor's space. If water is coming in now, we can install temporary protection, including nights, weekends and holidays. Your property manager arranges access to the roof and the tenant spaces. Electrical problems go to an electrician.
Before anything is priced, you get photos of each wall and drain we checked.Wall flashing can look intact while the backing behind it has failed. Our wall and penetration flashing work opens the flashing to check the wood and how the top edge is sealed. Rotted backing is replaced before new flashing goes on. If the wall itself is damaged, a mason or framer repairs it first. Resealing old flashing over rotten wood only lasts until the next storm. It also hides the rot, which makes the next leak harder to trace and more expensive to fix.
Water that gets behind wall flashing usually soaks the insulation along the base of the wall, and it can reach under the roof of the next tenant space. A few small core cuts tell us how far the wet area goes, and each one is sealed the same day with the space below protected. If the wet area spreads, we mark it on a roof plan and review it with the property manager before any extra work, since it may affect another tenant. That review matters because the cost may need to be shared or charged back under the leases, which is your call, not ours.
On a shopping center, the field of the roof can be in fair shape while each wall has a different problem. Roof coating restoration can extend the life of a sound field, as long as the membrane is clean and compatible with the coating. But a coating does not fix rotted wall backing or loose caps, so each wall gets the repair its own condition needs first. We price the wall work and the coating separately so you can compare that with a full replacement.
Drains matter just as much. If new insulation goes down, it can raise the roof around the drains and leave water sitting there. Our roof drain and scupper repair checks each drain, resets damaged flashing and adds extensions where needed. A cracked drain body or pipe goes to a plumber. Tenant HVAC units near the walls are coordinated with each tenant's contractor before the new roof closes them in.
That avoids cutting into a brand-new roof later to reach a curb.A shopping center roof covers many businesses, each with its own hours and customers. Our occupied building reroofing plan shows which tenant spaces sit under each day's work, where the crane sets up, how debris comes down and which parking areas or walkways close. Your property manager notifies tenants and decides on access and protection for each space. One tenant closing early does not mean the store next door can be ignored.
If we open a wall and find damage running into another tenant's space, we stop, show your manager what we found and wait until that tenant is notified before cutting further. If a mason or HVAC contractor needs to work first, 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. Material is staged away from storefronts and customer parking, and lifts are scheduled before stores open wherever possible.
Shopping centers across Berkeley and Oakland combine tenant spaces, common areas and shared roofs, often built in phases with different roof types. For centers near downtown Berkeley, we plan visits around store hours and deliveries. It helps to have the tenant list, a roof plan showing which tenant sits where, and any records of past roof repairs.
In West Berkeley and Emeryville, roof work has to account for tenant access, storefront protection and how water actually drains across a large roof. Berkeley's long dry season followed by heavy winter rain cracks sealants along walls, and the first storm finds the weak spots. We inspect every wall and drain on the roof, photograph what we find and write the repair plan for your center, with each repair tied to the tenant space below it.
Big box retail roofs usually have a single tenant, which makes scheduling simpler. For a shopping center, the closeout package includes photos of each rebuilt wall flashing, any replaced insulation and repaired drains, plus a roof plan marking which tenant space sits under each repair. Temporary repairs are labeled, and anything left for another trade is listed separately.
Apartment roofs also have many occupants under one roof, but each building's walls and hidden damage are different. For your center, the roof plan helps the property manager answer tenant leak calls quickly: they can see whether the space sits under a wall we rebuilt or somewhere else, and send us photos so we can respond. Walking the roof each fall, before the rains, catches most wall and drain problems early.
Tell us which tenants have reported leaks and send a roof plan if you have one. We will inspect the walls and drains and send a photo report with a clear repair plan.
