Restaurant Roofing
The roof over a restaurant kitchen keeps a visible record of what the kitchen sends up through it: a dark ring around the exhaust fan, a film on the membrane downwind of it, grease collected in the nearest drain. On a restaurant roof in St. Paul, MN we photograph all three and date the entry, because the observed condition documents residue and damage that can be compared during later visits. That record is the first thing an owner needs when deciding between a repair and a new roof.
Following the Grease Trail From Exhaust Fan to Drain
Cooking exhaust deposits fats and oils on the roof surface, and those deposits attack some membranes and clog drains. We trace the path from each fan to the nearest drain, mark how far the film spreads and take readings of the membrane along it. A fan with a missing or full grease containment tray tells us what the roof has been absorbing, and the photographs show whether the residue is spreading toward a seam.
Drains downwind of an exhaust fan get checked on every visit. A drain that holds grease slows during a thaw, and meltwater that ponds beside a kitchen roof softens the film and carries it into seams. Where the problem is persistent, a membrane option evaluated for the actual fat and oil exposure, including the PVC roofing type, can be specified for the kitchen zone. The drains and scuppers are cleaned and logged each time so the file shows a maintenance pattern.
Coring Roofs in Converted Lowertown Buildings
Lowertown includes a historic building district and converted restaurant spaces. Their roof assemblies need independent investigation; original building dates do not establish present layer counts or roof age. A restaurant in one of the converted buildings needs its roof read before anyone bids on it, because the layers are not known until they are cut. We take small core samples through the assembly and log what is actually there.
That cut also shows whether wet insulation has accumulated under older patching. In Lowertown, where Union Depot and CHS Field sit close to the converted buildings, a leak over a dining room is a visible problem, so each finding is recorded and acted on before the weather turns. The same coring step applies to a restaurant on University Avenue in the Midway, the district's main commercial corridor and the route of the Green Line.
Working Around Lunch, Dinner and Weekend Service
A restaurant earns its money in service hours, so the schedule starts with the closed hours and builds outward. Early morning is the quiet window before prep, and the roof is worked in sections that can be finished and sealed before the first delivery. Noise, dust and fumes are kept away from the dining room and the kitchen the way they are on any occupied building reroofing job.
Fire control is part of the plan. We avoid open flame and hot work near exhaust ducts and grease-coated surfaces, and we choose adhesives and sealants whose odor will not drift into the make-up air intake. The kitchen's exhaust fans are located on the plan so no one lays material across them, and the daily photograph shows the roof sealed and clear when the cooks return.
Logging Rooftop Units, Condensers and Winter Ice
A restaurant roof carries rooftop heating and cooling units, make-up air, walk-in cooler condensers and exhaust fans, all within a small area. Each is a curb or support and each is a penetration. We record them individually with photographs and readings, so a leak that appears beside one is traced to that unit and not blamed on the whole roof.
Winter adds ice and snow. The historical 1981 through 2010 Twin Cities annual snowfall normal was 54 inches, and drifts form against units and screen walls. Where heat escaping through the roof assembly melts snow, the water can refreeze at the nearest edge and form an ice dam over the entrance. Engineers in Ramsey, Dakota and Washington counties check roofs against a 50 psf ground figure, and our drift measurements support engineering review without establishing final roof load or remaining capacity.
Keeping the File That Lenders, Landlords and Franchisors Request
A restaurant operator often answers to a landlord, a lender and sometimes a franchisor, and each may ask for a roof report. We deliver a dated condition report with photographs, moisture readings, core findings and a list of repairs, so one document serves all three. For operators with several locations, the file can follow the format used for retail and restaurant chains, so the stores can be compared.
When a roof leak damages inventory, equipment or the dining room, the claim depends on showing when the damage began and what caused it. The photographs from before and after the repair, plus the record of the temporary measures, provide evidence for that review. A restaurant inside a shopping center or a hotel often depends on a landlord for the roof, and a tenant who holds a copy of the same file can answer questions faster.
We coordinate roof access with the kitchen exhaust lead and the building contact who can authorize equipment downtime. Work near a hood or duct includes the agreed protection and any cleaning or restart check by the responsible trade. The dated roof record identifies membrane repairs separately from kitchen-system maintenance, so when a leak recurs beside an exhaust curb, the building team can compare service dates and investigate the connection. Closeout photographs show the curb and surrounding membrane after the work is complete.
Questions We Hear
Does grease from the exhaust fan affect the roof warranty?
Warranty terms differ by manufacturer, and grease exposure is one of the conditions worth reading closely. Some membranes are rated for fats and oils and others are not. We read the warranty before work starts, document the condition of the surface near each fan, and keep the cleaning dates in the maintenance file.
How do adhesive fumes stay away from the kitchen's air intake?
Intakes are located on the roof plan before any material is opened. Odor-prone products are applied when the intake can be shut down or moved away from the work area, and low-odor products are chosen near it. The daily log records the products used and the time they were applied.
A ceiling stain appeared over a dining table. How do you find the entry point?
We begin with moisture readings on the roof around the area and trace them uphill, because water often travels along the deck before it reaches the ceiling. A core sample confirms wet insulation, and the leak is followed to the flashing, curb or seam that admitted it. Photographs of each step go in the file.
What does a lender or franchisor want to see about the roof?
A dated condition report with photographs, moisture readings, a list of open repairs and an estimate of remaining life. Evidence of recent maintenance, including drain cleaning near the exhaust, counts for as much as new material, since it shows the roof is being looked after.
Why do roofs on converted Lowertown buildings need cores before a bid?
Cores show what the roof is made of, and existing records may not establish later changes in a converted building. A sample reveals the layers, the insulation condition and the layer count at the sampled location. With that known, the bid reflects the real assembly instead of an assumed one.
