Restaurant Roofing in Richmond, CA
Restaurant roofs have a problem most roofs never see: grease. Kitchen exhaust fans push cooking grease out onto the roof, and over time it soaks into the membrane around the fan curb. Many single-ply and asphalt-based roofs soften, swell or blister under grease, and once that happens a patch or coating will not stick. The flashing at the exhaust curb usually fails first. Fixing it means removing the grease-damaged membrane, rebuilding the curb flashing with material that can stand up to it, and often adding a grease containment system so it does not happen again. Hood and fan cleaning crews handle the equipment side.
Send us the exhaust fan locations, any roof records and the name of the manager we should coordinate with. We inspect the roof before choosing a repair, and your team decides how the kitchen and dining room are protected while we work. The price is based on how far the grease damage actually reaches. Exhaust fans, hoods and their service stay with the kitchen exhaust contractor, and every trade handles its own part of the job.
How far does the grease damage go?
A stained roof around an exhaust fan is not proof the membrane is ruined, but it needs a close look before anyone assumes a patch will hold. Our commercial roof repair inspection checks whether the membrane around the fan has softened, swelled or lost its bond. TPO and PVC repairs are heat-welded and need clean, sound sheet; other roof types use their own methods. Some stained membrane can be cleaned and kept. Membrane that grease has broken down has to be cut out. The repair is priced to sound material, not just the first visible crack.
Grease often spreads well beyond the fan, carried by wind and rain toward drains. We check how far it has gone and where the roof needs extra prep or replacement. Roof coating restoration is only an option on surfaces that are clean, sound and compatible with the coating. A coating will not fix membrane damaged by grease just by covering the stain. The price separates required repairs at the exhaust curb from optional coating work on the rest of the roof.
The exhaust contractor goes first
Sometimes the fan has to be cleaned, serviced or lifted before we can reach the curb flashing. The kitchen exhaust contractor handles fan performance, clearance and cleaning. Our rooftop equipment curb and support work identifies the roof detail at the curb and what the exhaust contractor needs to do first. A new layer of roofing will not fix a fan that keeps throwing grease, so the bid keeps the exhaust work separate from the roof repair that follows.
The flashing up the curb needs solid wood and insulation behind it and a membrane that can handle grease exposure. We check what is under the flashing and remove anything that cannot hold a lasting repair. Structural or curb-height questions go to an engineer or the designer. A thicker new roof can shorten the curb and affect clearances around the fan. The price lists those items before a full reroof is treated as ready. You can compare complete options, with the roofing and exhaust work each shown where they belong.
Working around the kitchen and dining room
An opening above the kitchen or dining room can affect more of the restaurant than the spot where the leak showed. For reroofing occupied buildings like restaurants, we share the planned openings, debris routes and material deliveries with the manager. They decide how food areas and guests are protected and when we can work, often before opening or after close. Exhaust service, equipment and electrical work stay with the right trades. Patching any test openings is included in our price, so the bid reflects the real work instead of one protection setup for every room.
If more damage turns up, the opening may grow and reach another prep area or the dining room. We explain the larger area before removing more and review the effect with the manager. Temporary roofing may stay in place while an exhaust or structural issue gets sorted out. The operator tells us about kitchen exhaust schedules, dining hours and interior protection before rooftop work begins, and arranges our inspection access. Electricians check any affected equipment. Temporary patches are recorded separately from the finished curb repair.
Checking the insulation underneath
The insulation around a leaking exhaust curb can be wet even where the membrane still looks fine. Infrared scans help find likely wet areas, but the readings depend on how the roof is built and the conditions during the scan. We confirm with core cuts wherever the decision to keep insulation depends on it. Each test spot is patched, and the manager knows what is below. A stain on the surface does not tell you the condition of every layer. We explain how the findings change the repair, rather than assuming the whole restaurant roof is in the same shape.
A local curb repair and a larger reroof should each include complete flashing at every curb and any exhaust work needed. We list the membrane that can stay, the curb details and the insulation each option requires. The designer and other trades decide on items that fall to them. Final photos show the finished curb and the insulation we kept. You can tell finished work from temporary patches and open exhaust items, so future spending goes where it is needed. Any future coating can start from those repairs instead of being spread over membrane that grease has already ruined.
Restaurant roofing in Richmond
For restaurant roofing in Point Richmond and nearby neighborhoods, every exhaust curb and the flashing around it gets its own check. Send us your roof records and the manager who arranges access. We inspect the roof before recommending a repair, and your team reviews protection and material handling. The price follows the grease damage we actually find and the exhaust work needed, with test openings and access listed.
Other food and retail buildings have similar roof equipment with different issues. A grocery store roof carries heavy refrigeration equipment and condensate lines. A shopping center roof covers several tenants, often including more than one restaurant. We document each restaurant's curb repairs separately, so a future project starts from what we actually inspected there. Grease damage and kitchen schedules vary from one building to the next.
Commercial Roofing Questions
Can a coating fix a grease-stained roof?
Not if the grease has damaged the membrane. That material has to be removed and replaced. Coating only works on clean, sound, compatible surfaces.
What does the exhaust contractor need to do first?
Clean or service the fan, and lift it if needed, so we can reach the curb. If the fan keeps throwing grease, that has to be addressed too.
What if more roof needs to come off over the kitchen?
We stop and show the manager the larger area. Protection and work hours are updated before we go further, and test openings are patched.
What should we keep after the repair?
Photos of the finished curb flashing and insulation, plus a list of temporary patches and any exhaust or other trade work still open.
