A hotel reroof is a revenue decision as much as a roofing one. Rooms under an open section come off the sales sheet, and in a market where tourism has been the main economic driver since the 1940s, a room out in July costs more than a room out in November. Coeur d'Alene, ID has a short peak and a long shoulder, and the roof schedule should live in the shoulder. The new roof also needs to be finished before the first big storm of the cold months, because the design snow load is 60 psf.
We write the hotel bid in two currencies: dollars and room-nights. The roofing scope carries a price. The sequence carries a count of rooms affected and for how long. An owner or an operator can trade the two, spending a little more on a night crew to save rooms, or taking a section of rooms offline to save on labor.
The Call: Count Room-Nights Before You Count Squares
We start with the room plan. Which floors sit directly under the roof? Which wing has the oldest leaks? Which rooms are already out of service? A top-floor room under a failed section may be offline already, and fixing that section first brings it back to the sales sheet.
The sequence follows the answer. We work on the wing with the lowest occupancy forecast first, shift the loudest steps to the hours when guests are out of the room, and keep an eye on check-in times. The front desk gets a daily note that says which rooms may hear work and which will not. The operator can offer affected guests a different room before they ask, and the housekeeping lead can plan the day around the rooms that will be blocked. A hotel that handles this well turns a construction project into a non-event on the review sites, and the notice costs nothing to write. It also tells us which rooms are the first ones guests will complain about, so we move that work to the earliest hours.
What It Costs: Rooms, Equipment and Amenities
A hotel roof carries more than the field. Rooftop mechanical units, exhaust risers from every bathroom, the stair and lift penthouse, the pool equipment room and the kitchen exhaust each add a curb or a boot. Hotels with sloped sections, mansard edges or parapet walls around a flat core add flashing lines. Added together, those details can outweigh the field membrane in the bid, and they are the lines where two contractors disagree most. A bath exhaust boot is a small item, but a hotel with many guest floors has a lot of them, and a count in the bid that is low by a few dozen shows up later as a change order.
The occupied-building premium is the other swing. Night work, weekend phases and quieter fastening cost more per day. Protection of entries, porte-cocheres and pool decks adds more. We separate all of these from the base roof so the operator can see which choices save rooms and which are only a convenience. A night crew, for example, costs more per hour but can keep a whole wing sold, while quieter fastening costs more per square and protects the guests on one floor. Each tradeoff has a price and a room count beside it.
Where It Fails First: Porte-Cocheres, Pool Rooms and Bath Exhaust
Hotels fail at the extremities. The porte-cochere and entry canopy hold snow and shed it onto arriving guests. The pool room has a humid interior that pushes moisture into the roof assembly from below, so the insulation over it can soak without a visible leak. Bath exhaust risers cross the membrane in dozens of places, and each boot is a chance for a leak.
The Village at Riverstone along Northwest Boulevard combines a 14-screen cinema, a Hampton Inn and retail space, and Silverwood Theme Park near Athol and Boulder Beach Water Park beside it are a large seasonal hospitality and attraction roof stock. A seasonal attraction or a lodging property in this market spends the summer as a destination and the winter under snow, so the roof has to handle both extremes. For a hotel the gap between the two matters in a specific way: summer heat softens adhesives and stresses seams on a dark membrane, and winter cold stiffens the same seams. A reflective membrane takes some of the summer stress off, and a firm cover board takes some of the winter stress off. The operator can see both choices on the alternates list.
What the Code Sheet Says: Snow, Wind and Energy
For a hotel, the 60 psf snow load shapes the entry canopy and the drift behind taller sections, and the wind speed shapes the fastening along the edges of a multi-story building.
A replacement brings the insulation up to the current energy-code requirement, and the extra depth raises every curb. Wet snow is dense, so the drift pocket behind a taller wing or a mechanical penthouse can add far more than the open roof carries. We show those checks to the operator before the bid is final.
Alternates: What Protects Rooms and Reviews
Hotel operators and owners choose from this list:
- Night phases over guest floors
- Temporary covers and sound mats above occupied rooms
- Snow guards or a retention layout over entries and the porte-cochere
- A vapor retarder or moisture check over the pool room
- A cool-roof membrane for a lower cooling load
- A twice-yearly roof visit written into the engineering schedule
The moisture check over the pool is worth a close look. Humid air rising into a roof for years soaks the insulation, and finding it during a reroof is cheaper than finding it after a ceiling stain in a guest room. A core sample over the pool, taken before the bid, tells us whether the insulation there needs replacement or can stay, and the same visit counts bath exhaust boots by floor so the quantity in the bid matches the roof.
Closeout: A File for the Engineer and the Brand
The chief engineer receives a roof plan, a drain map and a list of boots and curbs. The owner and the brand standards office receive the warranty documents and photos. The phasing follows the pattern of occupied building reroofing, and a yearly preventive roof maintenance visit protects the investment. A hospitality group with several properties can add a roof asset management plan. A hotel shares entry-canopy and rooftop-unit details with a shopping center and guest-floor leak risks with an apartment building. TPO is a common choice, and hotels in Riverstone and Athol follow the same plan.
Commercial Roofing Questions
How many rooms go offline during a reroof?
Only those directly under the open section, and only for the days it is open. We work wing by wing to keep the count low.
Can work happen while guests are in the building?
Yes, with quieter methods, daily notices to the front desk and louder steps timed for hours when guests are out.
Why does the pool room need special attention?
Humid air pushes moisture up into the roof assembly. A moisture survey shows whether the insulation is wet, and a vapor retarder keeps it from happening again.
What about a porte-cochere in winter?
Snow that slides from the main roof lands on arriving guests. Snow guards and a drift check keep it on the roof.
Should the reroof wait for the off-season?
Usually the shoulder season is best, between summer peak and the first hard freeze. Adhesives and seams need workable temperatures.
