Commercial roof work in Coeur d'Alene, ID is priced by snow. The city's own design sheet carries a 60 psf ground snow load, rates weathering as severe and requires ice barrier underlayment, and those three items decide where the money goes on a hospital roof, a school roof or a retail strip alike. The membrane brand matters less than the drains, the drift pockets and the edge metal.
Low-slope and metal roofs across the city are replaced, repaired, recovered and coated on the same pricing frame: base scope, alternates and change-order triggers each on their own line.
What We Roof: The Buildings the City Supports
Coeur d'Alene had 54,628 residents in 2020, sits at about 2,247 feet and is the seat of Kootenai County. Its largest employer is Kootenai Health, a 329-bed hospital, and the Coeur d'Alene School District is second. That pairing says a lot about the roofs: institutional buildings with mechanical equipment, tight schedules and owners who plan long.
Interstate 90 runs through the city with exits at Northwest Boulevard, US-95 and Sherman Avenue, and commercial buildings gather along those routes. Rather than guess at any individual roof, we describe what we look for: how it drains, what it is made of, how old the flashing is and where the snow collects. The first walk answers those, and the bid follows.
Hospital and school roofs bring warranty files, phasing and quiet-hour rules. Retail and light commercial roofs bring tight schedules and open doors. We build the bid so either reader can follow it: the same lines, the same alternates and the same change-order triggers, so bidders compare line by line.
What the City Sheet Says
City Building Services publishes adopted codes and design criteria, and every commercial roof submittal is reviewed against them. The city's values are the 60 psf snow, 115 mph wind and 24 inch frost line, with Seismic Design Category C, severe weathering and required ice barrier underlayment, all under the statewide 2018 codes.
Each number touches the roof. Snow load sets the insulation, deck and drain demands. Wind speed sets fastener density at corners and edges. Ice barrier sets the eave and low-slope details where meltwater refreezes. A submittal that carries the system data, the uplift rating and the fastening pattern keeps the permit from holding up the start.
Seismic Design Category C and the frost line matter to a few roof elements: equipment restraint on rooftop units and the footing depth for ground-level supports tied to a roof. The mechanical and structural trades own those. We coordinate where the roof meets them, at curbs, supports and penetrations, and call a hold point if the interface is unclear.
The First Walk: What We Check Before We Price
Drains and scuppers first, since a roof that does not drain in January is a roof that fails in March. Then drift pockets behind parapets and rooftop units, where wet snow loads the deck unevenly. Then edges, flashings and penetrations, then the seams.
We cut cores and run an infrared moisture survey where we suspect wet insulation, because the result decides between repair, recover and replacement. The inspection produces a map, photographs and a priced list. Each item is marked patch or fix, and the owner decides what goes ahead.
Access gets checked on the same visit. Where the hatch is, whether a ladder reaches, what is below the work area and where materials can stage. A roof that is hard to reach adds hoisting or lift time, and that belongs in the bid before the crew arrives and not after.
What It Costs: Options in Order
Repair is the cheapest and the shortest. It fits a roof with isolated failures and dry insulation. A coating adds years to a sound, dry membrane without a tear-off. A recover adds a new membrane over a dry existing roof, which saves the tear-off line and adds weight the engineer must approve. Replacement removes the old roof and starts over. It is the answer when the insulation is wet across a wide area or the repair spend keeps chasing the same failures.
We price what the roof needs, with repair, coating and replacement shown side by side when more than one makes sense. Tear-off, insulation, cover board, edge metal and drains are separate lines, and wet insulation found mid-job carries a unit price already written into the bid.
Timing changes price. A job booked in winter for spring can lock a crew and a material date. A job called in during a leak costs more, because temporary protection comes first and the schedule is set by the weather. Owners who walk their roofs in October and decide in November have the most choices and the lowest premiums.
Weather Over the Year
About 25.4 inches of precipitation falls in a year, the July mean is near 70 F, the January mean near 31 F, about 18 days top 90 F, and the record low is minus 30 F. That swing is hard on seams, sealants and flashings, which move every day with the temperature. A few miles west, Post Falls gets about 59 inches of snow, and totals climb east along I-90.
Work windows follow the weather. Single-ply installs and coatings run best from spring thaw to early fall. Emergency calls run around the clock, holidays included, with a temporary closure first and the permanent fix when conditions allow. The windstorm of November 17, 2015 put about 238,000 customers in the region without power, which is the reason we do not price perimeters at the minimum.
Emergency work gets its own rule set. When a leak opens over a tenant, the first visit stops the water, protects the contents and records the cause. The permanent repair waits for dry surfaces and workable temperatures. A temporary closure that holds through a thaw costs a small fraction of the interior damage it prevents, so we respond fast and plan the fix after.
Winter inspections have limits, and a report written in January says what could not be seen. Snow hides seams and ponding, so we read edges, drains and ceilings, run a drone pass where it helps and schedule the full walk after the melt.
Around the City: Nearby Places We Work
Inside the city, downtown and Riverstone carry their own building mixes, and the same work reaches Post Falls, Hayden and Riverbend Commerce Park. Whatever the address, we send a priced scope to the owner or the GC, and the owner decides what stays in.
Closeout is the same everywhere: a walk with the GC, photographs of every drain, seam and flashing, and the maker's warranty paperwork submitted on time. The record goes to the owner, and the next visit starts from it.
Commercial Roofing Questions
What snow load do you design to?
The city sheet lists 60 psf for ground snow. The engineer sets the roof load from it and we price to the detail it requires.
Do you work on hospital and school roofs?
We plan work on institutional roofs around quiet hours, phasing and the facility's rules.
How fast can you start?
Emergency closures the same day. Planned jobs follow the material lead time and the weather.
Do you handle the permit?
We prepare the submittal with the system data and wind rating the city checks against its sheet.
What if I cannot get photos of the roof?
We start with a drone pass or a walk, whichever is safe, and the report carries the photographs.
