Mystic Commercial Roofing Contractor
Membrane Around Kitchen Exhaust Fans That Holds Up to Grease
As a Mystic commercial roofing contractor, we replace roofs on restaurants, inns, and shops with membrane and flashing built for kitchen exhaust, crowded rooftop units, and constant service traffic.


Mystic Commercial Roofing for Kitchens, Inns, and Shops
Mystic commercial roofing work often lands on restaurant and hospitality buildings, where the roof is crowded with kitchen exhaust fans, make-up air units, and condensers. Grease from exhaust fans softens some membranes over time, so the area around each fan needs a plan of its own.
Mystic is a village split by the Mystic River between the towns of Groton on the west side and Stonington on the east side. Which building department issues the roof permit depends on the side of the river your building sits on, and we confirm that with the right office first.
- Grease-resistant membrane or a protective pad ring around each exhaust fan
- Raised curbs and new flashing on make-up air units and condensers
- Walkway pads on the paths hood cleaners and HVAC techs walk every visit
- Tear-off timed around lunch and dinner service so kitchens keep cooking
Commercial Roofing Trouble on Mystic Restaurant Roofs
Restaurant roofs wear out in different places than an office roof. These are the signs staff notice and the causes we find above them.
Drips Near The Hood Line
Water appearing along the kitchen hood or near the exhaust duct usually starts at the fan curb overhead, where grease and heat have broken down the membrane and flashing.
Grease Damage Around Kitchen Exhaust Fans
Grease softens and swells some membranes until seams open. The damaged area is cut out, and grease-resistant membrane and a catch box go in around the fan.
Stains Over The Dining Room
Ceiling spots in the dining area often sit under a condenser or make-up air unit, where curb flashing has cracked from vibration and years of service visits. Stains that grow in July point to units running hardest.
Cracked Curb Flashing Under Rooftop Units
Units that run hard all season shake their curbs loose. Curbs are rebuilt or raised, and new flashing is welded or taped up each side.
Leaks After A Service Visit
Owners sometimes notice a new leak right after the hood cleaner or HVAC tech has been on the roof, a sign of punctures along the path they walked.
Worn Paths Across The Membrane
Dropped tools and heavy boots wear through membrane along service routes. Walkway pads mark the path and protect the roof underneath it. Small punctures found during inspection are patched first.
How New Commercial Roofing Helps Mystic Restaurant Owners
A replacement planned around the kitchen keeps food service running and stops the leaks that tend to show up mid-shift.

Fan Curbs Built For Grease And Heat
Kitchen exhaust is the hardest spot on any restaurant roof. Grease-resistant membrane, a catch box under the fan, and a hinged fan base that lets the hood cleaner work without lifting the curb flashing keep that corner sealed. Fewer leaks near the hood means fewer interruptions on the cook line during the busy season.
Service Visits Stop Causing Leaks
Walkway pads from the roof hatch to each unit give hood cleaners and HVAC techs a protected path, so tools and boots stay off the open membrane.
Cooler Dining Rooms In Summer
A white TPO surface reflects sun that a dark roof soaks up, easing the load on the units cooling a packed dining room.
Kitchens Keep Running During Work
Tear-off around the kitchen happens between meal services, and exhaust fans are shut down only when the kitchen manager agrees.
Commercial Roofing Systems for Mystic Hospitality Buildings
Restaurants, inns, and shops each get the system that fits their equipment and how often people walk the roof.

TPO Roofing
Reflective TPO with welded seams suits dining rooms and guest rooms that run air conditioning hard, and grease-resistant versions can go around exhaust fans.

EPDM Roofing
EPDM fits inns and shops with many vents and plumbing stacks, though areas near kitchen exhaust need a grease-resistant membrane or a protective ring.

Industrial Roofing
Banquet kitchens and larger hospitality buildings carry heavy equipment, so we add raised curbs, sturdier membrane, and walkway pads along service routes.

Commercial Metal Roofing
Standing-seam metal fits porches, sloped dining additions, and outbuildings, and it sheds snow and rain away from entrances guests use.

Restaurant roofs follow a schedule built around the kitchen, from the first walk to the last flashing.

- ROOF WALK
Inspect Your Roof
We core the roof, check every fan curb for grease damage, and map each unit and the paths service crews take across the membrane. Hood cleaning records help show how long grease has built up.
- PERMIT SIDE
Confirm The Right Permit Office
Depending on which side of the Mystic River the building sits, we check permit needs with Groton or Stonington before work is scheduled. That office's requirements go into the schedule.
- OFF-HOURS
Tear Off Between Services
Crews strip sections in the hours between lunch and dinner, or before opening, and close every opening before the evening rush. Debris goes out the back, away from guest parking.
- FAN CURBS
Rebuild Fan And Unit Curbs
Exhaust fan curbs get grease protection and hinge kits, and unit curbs are raised or rebuilt before membrane goes on. Condensate lines are piped to the nearest drain.
- WALKWAYS
Membrane, Flashing, And Walkways
Membrane and flashing finish each section, then walkway pads go down along every service route from the hatch to the units. Staff get a short note on where to walk next time.

Mystic Restaurant Roof Questions
Restaurant and inn owners ask these before planning a new roof.
How do you prevent grease damage around kitchen exhaust fans?
Start with the right materials. Grease-resistant membrane around the fan, a grease catch box, and regular hood cleaning keep grease from soaking the roof. A hinge kit on the fan lets cleaners tilt it back without damaging the curb flashing underneath. Checking the fan area at each cleaning catches trouble early.
Can a restaurant roof replacement happen while we stay open?
Usually, yes. Tear-off runs between meal services or before opening, exhaust fans go down only with the kitchen manager's okay, and each section is sealed before the dinner rush so service carries on below.
Which town issues roof permits in Mystic?
It depends on the side of the river. Mystic is split by the Mystic River, with the west side in the town of Groton and the east side in Stonington, so the building's address decides which building department handles the permit.
Do inns and shops in Mystic need a different roof than restaurants?
Often they do. Inns and shops have fewer grease sources, so the choice turns more on slope, insulation, and the number of vents and units. Restaurants need grease protection at every exhaust fan on top of that. Guest rooms under the roof also call for quieter work hours.
