Roofing Hotels That Fill Up on Football Saturdays
Hotel demand in this market swings harder than almost anywhere else in the region, driven by University of Michigan football Saturdays that can fill every room within a twenty-mile radius months in advance. That swing shapes hotel roofing scheduling as much as the building itself does, and a roofing contractor who doesn't track the football calendar is going to propose work windows that simply don't exist for a hotel manager here.
Hotel Stock From Briarwood to the Airport Corridor
Hotels cluster around a few distinct nodes in this market: the Briarwood Mall area along State Street and I-94, downtown boutique properties near campus, and the corridor out toward Romulus that serves Detroit Metro Airport traffic. Each has a slightly different roof profile. The Briarwood-area and airport-corridor properties tend to be larger flag hotels with big low-slope roofs over guest wings and a separate roof section over the lobby, restaurant, and meeting space. Downtown boutique properties are often older buildings converted to hotel use, carrying the same retrofit flashing challenges we see in converted medical office buildings, added mechanical equipment layered onto a roof that wasn't originally built for it.
Game Weekends Leave No Room for Downtime
A hotel that's sold out for a home football Saturday can't tolerate a roof leak dripping into a guest corridor, and it definitely can't tolerate a crew staging equipment in a lot that valet and guest parking need that weekend. We build hotel project schedules around the football calendar specifically, avoiding home game weekends and the Friday-Saturday windows around them entirely, and we confirm graduation weekend and other high-demand dates directly with hotel management rather than assuming a generic seasonal slow period exists. The actual slow windows tend to be narrower than owners expect once you account for graduation, move-in weekend, and the busier home game dates.
Pool, Kitchen, and Laundry Penetrations Overhead
Hotels carry a specific mix of rooftop penetrations tied to amenities most other commercial buildings don't have: pool mechanical and dehumidification equipment, commercial kitchen exhaust for the restaurant or banquet space, and heavy-duty laundry exhaust running long hours. Each of these runs hotter and more continuously than standard HVAC, and each needs flashing detail built for that specific load rather than a generic curb treatment. Pool area roofs in particular deal with elevated humidity from below in addition to weather from above, which changes how we think about vapor management in the roof assembly over natatoriums and indoor pool enclosures.
- Scheduling anchored to the home football calendar, not a generic slow season
- Reinforced flashing at pool dehumidification and natatorium penetrations
- Kitchen and banquet exhaust curb detail sized for continuous heavy use
- Laundry exhaust flashing built for long-duration, high-heat operation
- Guest-wing phasing that avoids working directly over occupied rooms overnight
- Coordination with hotel management on valet and parking lot staging
Guest Room Wings vs Low-Slope Common Areas
The roof over a hotel's guest room wing and the roof over its lobby, restaurant, and meeting space often need different treatment even on the same property. Guest wings are long, relatively simple membrane fields punctuated by individual room HVAC units, where the main risk is many small leak points rather than one large failure. Common area roofs carry heavier concentrated mechanical loads, kitchen exhaust, larger HVAC units for open lobby and ballroom spaces, and sometimes rooftop generator equipment for backup power. We survey and often phase these two roof types separately, since a hotel doesn't need to shut down guest room access to work on the restaurant roof, and vice versa.
Freeze-Thaw and Ice Damming Over Guest Corridors
Michigan winters put the same freeze-thaw stress on hotel roofs as any other flat roof in the region, but ice damming over a guest corridor creates a specific problem: water finding its way through a compromised parapet or unit curb flashing directly above a room a guest is paying to sleep in that night. We prioritize parapet and curb flashing inspection on guest wings heading into winter specifically, since the cost of a guest complaint and a comped room is a different kind of expense than a maintenance ticket on an empty warehouse.
Questions Hotel Facilities Managers Ask
How do you avoid scheduling conflicts with football weekends?
We build the project schedule around the home game calendar first, confirming actual slow periods directly with hotel management rather than assuming a standard seasonal window, since graduation and other high-demand dates narrow it further.
Can you work on the restaurant roof without disturbing guest rooms?
Yes, in most cases. We survey and phase guest wings and common area roofs separately, since they usually carry different equipment loads and don't need to be worked on at the same time.
What's different about pool area roof penetrations?
Natatorium and pool dehumidification equipment adds elevated humidity exposure from inside the building in addition to normal weather from outside, which changes how we approach vapor management in the roof assembly there.
How do you handle staging around valet and guest parking?
We coordinate directly with hotel management on lot staging and crane placement to avoid disrupting valet operations or guest parking, particularly around high-occupancy weekends.
Why prioritize guest wing flashing before winter specifically?
Ice damming over a guest corridor risks water intrusion directly above an occupied room, and the cost of a guest complaint or a comped stay makes preventive flashing inspection worth prioritizing before the freeze-thaw season hits.
