Flex industrial roof repair in Berkeley, CA: leaking drains, wet insulation and drain flashing fixed across office, shop and storage tenants.
Property Types We Roof | Berkeley, CA
Flex industrial buildings put offices, light production and storage under one long, low-slope roof, and that roof drains to a handful of drains or scuppers. When the membrane around a drain splits or the clamping ring loosens, water goes down around the drain and into whatever space sits below, which might be an office in one bay and a shop floor in the next. On a flex building in Berkeley, CA, one bad drain can mean calls from two tenants who never talk to each other. That makes it easy for a small drain problem to go unreported for months, with each tenant assuming someone else already called.
We start by clearing the drain and checking what is underneath, then look at nearby seams, curbs and walls for another source. If water is coming in now, we can install temporary protection the same day, including nights, weekends and holidays. Your property manager arranges access to the roof and to the tenant spaces below. Plumbing inside the building goes to a plumber, tenant equipment stays with its owner, and wet electrical goes to an electrician.
Before we price anything, you get photos of each drain and what we found around it.Our roof drain and scupper repair separates cleaning from repair. Cleaning restores flow. Repairing a drain means pulling the clamping ring, checking the membrane and drain bowl for cracks or rust, and resetting it with new flashing that matches the roof. If the drain body or pipe below is cracked, a plumber needs to look at it. We cannot see inside the pipe from the roof, so we tell you plainly when it needs a camera or a plumber's inspection.
A drain that has leaked for a while usually leaves wet insulation around it, and it may spread under the roof into the next bay. An infrared moisture survey shows where the wet areas likely are, and a few small core cuts confirm the edges. We seal each core the same day and coordinate with the tenant below. Those results decide whether the repair stays at the drain or grows into a larger section. If it does grow, we mark the new boundary on a roof plan before any extra work is approved.
Wet insulation around a drain has to come out. Our insulation and cover board replacement removes it back to dry material and installs new boards, tapered toward the drain where it helps water move. If the deck under it is rusted or soft, an engineer reviews it first. New insulation can change the roof height at the drain, so we check that the drain will still sit low enough to drain properly, and add an extension or sump where needed.
If the rest of the roof is sound, a coating can extend its life, but only once the drains and wet areas are fixed and the surface is clean and compatible. A coating does not repair a broken drain or wet insulation. We also look at nearby curbs and equipment, since tenant units often sit close to drains. Any HVAC or equipment work is coordinated with the tenant's contractor. You get a side-by-side of a targeted repair, a coating and a larger replacement. That way you are comparing complete jobs, not just the price per square foot.
On a flex building, one roof section can sit over a storage bay, a workshop and an office. Our occupied building reroofing plan shows each tenant space under each day's work, where material gets lifted and how debris comes down. Your property manager notifies tenants and decides on access and protection for each space. A storage tenant may be fine with a tarp; an office tenant may need the area closed.
If we open the roof and the wet insulation runs over another tenant's space, we stop, show your manager what we found, and wait for that tenant to be notified before cutting further. If a plumber or another trade 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, what is temporary and what is next. Tenants hear about delays through your manager, not through water on their desks.
Flex industrial roofs around Berkeley and Oakland often cover office, production and storage space in one continuous roof, and the drains serve every tenant at once. For properties near downtown Berkeley, we plan visits around tenant hours and need to know which spaces have leaks. Any drainage drawings or past repair invoices help us decide which drains to look at first.
In West Berkeley and Emeryville, many flex buildings are older industrial structures that have been divided and re-divided, so drains do not always line up with tenant walls. We trace each drain to the space it serves and note which tenants could be affected by work there. Berkeley's long dry season followed by heavy winter rain means drains that collected debris all summer get tested hard in the first storm. We inspect every drain and price the repair on what we find on your building.
Manufacturing plant roofs tend to have more equipment near the drains and a single operator below, which makes coordination simpler. On a flex building, the closeout package includes photos of each repaired drain, the replaced insulation and new flashing, plus a roof plan marking which tenant space sits under each repair. Temporary repairs are labeled, and plumbing or equipment items are listed for the right trade.
Office building roofs have similar tenant coordination, but each building's drains and hidden damage differ. For your flex building, the roof plan helps the property manager answer tenant leak calls quickly: they can see whether the space sits under a drain we rebuilt or somewhere else, and send us photos. Regular drain cleaning before the rainy season also prevents a lot of these calls. Strainers that are missing or broken should be replaced at the same time.
Tell us which tenant spaces have leaks and send any drainage drawings you have. We will inspect every drain and send a photo report with a clear repair plan.
