Restaurant Roofing in Missoula, MT
Restaurant Roofing
The roof over a kitchen fails where the grease lands, and the repair has to be sequenced so the kitchen loses as few service hours as possible. Exhaust fans throw grease onto the membrane around their housings, and some sheets soften and swell under that film. The first step is to find where the grease collects, because the cleaning, the curb repair and the membrane choice all follow from it. In Missoula, MT, a restaurant roof also takes the weight of winter, so the order of work matters twice.
We map a restaurant roof job around the kitchen's schedule, the exhaust layout and the weather window, then we price it. The owner sees which hours the hood fans are off and which days the crane pick happens.
Trace the grease
We start at the exhaust fans. Grease runs down the housing, drips onto the roof and settles in a dark film. We look at the membrane around each fan for swelling, softening and discoloration. We check the grease containers and catch pans, which often overflow onto the sheet.
Then we look at the curb flashing, the fan base and the duct penetration. A cracked sealant joint or a loose fastener lets water into the roof. The report names each fan, shows a photo, states what to change and ranks the fix by urgency, so the owner can fund the worst fan first. Often the fix is a catch pan, a cleaning interval or a short duct repair, and each of those is a modest line compared with replacing a membrane that grease has already ruined. When the sheet itself has swollen, we say so and price the section that needs to come out. A roof cleaned on schedule lasts years longer than one left to collect grease. Kitchen hood cleaners often work on the roof, and their runoff lands on the sheet. We ask who cleans and how, and we suggest a plastic pad under the work area. The report shows the owner where to put it and when to replace it.
Sequence work around service
A kitchen cannot close for a roof job, so we work around it. The crew coordinates with the kitchen manager and the hood cleaning contractor. Fans are shut down only for the minutes needed to reset a curb or rebuild a flashing, and the work happens outside the busiest hours.
The staging area sits away from the kitchen door and the dumpster. Deliveries keep their usual time. The material hoist runs early in the day, before the lunch rush. Each section of the roof is dried in before the crew leaves. Where a dining room sits below the work, we install interior protection first, over the tables and the bar, and we leave it in place until the section is dried in and checked. Staff are told which areas are closed and for how long, so nobody is surprised by a ladder or a tarp. The sequence gets written down and shared before the first day, so staff know what to expect. Dining rooms, bars and patios below the work area get their own notes. Noise limits, dust control and the hours of the crew are in the scope. If a private event is booked, the manager tells us and we move the loudest work.
Respect snow and thaw
Missoula averages about 39.5 inches of snow a winter, with snow on the ground about 120 days a year, and about 45 days a year never rise above freezing. Snow can pile against rooftop equipment and parapets, and meltwater runs to the nearest low point. Drains and scuppers have to be clear before the first storm.
Warm exhaust melts snow around a fan, and the water refreezes a few feet away. That cycle works on the sealant and the seams nearby. We check those zones in fall, and we look at gutters and downspouts for ice buildup. A drain and scupper check is a short item that prevents a winter pond. The design ground snow load is 40 psf, which a roof with extra equipment must carry with margin. A restaurant that has added a walk-in cooler, a new hood or a patio heater over the years may have changed the load path without anyone checking. We look at the supports and the deck below any added equipment, and we flag signs of deflection before the next storm.
Pick the membrane for grease
Grease attacks some roofing sheets and spares others. A PVC membrane resists fats and oils better than most. A KEE-modified sheet adds plasticizer resistance for heavier exposure. TPO may do for a restaurant with little exhaust on the roof, at lower cost.
We compare options for each building, with installed cost, expected service and repair path. A roof with several exhaust fans clustered in one area can use a protective pad or a more resistant sheet in that zone alone. That keeps the cost down without leaving the grease zone exposed. The roof file records the choice and the reason. Exhaust is not the only contaminant. Dumpster enclosures near the building, compost bins and rooftop herb gardens can all bring moisture or organic matter to the surface. We note them and tell the owner what each does to the sheet.
Plan for the neighborhood
Restaurants sit in different parts of Missoula. The city has more than 60 National Register buildings, which raises questions about approvals and materials for older downtown properties. North Reserve Street carries more than 30,000 vehicles a day, which shapes delivery and staging. A restaurant in downtown Missoula may have tight alley access and a shared wall, while one on North Reserve Street has a parking lot and a drive lane.
We ask about access, adjacent buildings and local rules at the start. The answers go into the scope. A hotel with a restaurant adds guest areas to the same plan, and a grocery store with a deli adds refrigeration. Each shares details with a restaurant roof, and the walk records the differences. Near the University District, student demand shapes the calendar as much as the weather does.
Close out with a clean record
The closing walk with the manager covers a water test of the drains and a check of every flashing. The punch list is cleared before the crew leaves, and the manager signs it. The photographs, the cleaning schedule and the next review date go into the file.

Questions About Restaurant Roofing
How often should a restaurant roof be cleaned?
It depends on the exhaust volume and the catch pans. We recommend a check each season and a cleaning when the film reaches the membrane, with the interval written into the file.
Can a kitchen keep cooking during roof work?
Mostly. Fans are shut down only for short resets outside the busiest hours, and we coordinate with the kitchen manager and hood contractor.
Which roof membrane resists grease best?
PVC and KEE-modified sheets resist fats and oils better than most. We compare cost and service for each building before recommending one.
Why do restaurant roofs leak near the fans?
Grease softens the sheet and cracks the sealant around the curb. A catch pan that overflows makes it worse. A cleaning and a flashing repair usually fix it.
What should an owner send to start?
The roof plan, the exhaust layout, the kitchen schedule and the access constraints. We then map the staging area and the shutdown windows.
