A maintenance program costs less than the first change order it prevents. That is the whole argument, and the roof under a 60 psf ground snow load makes it easy to check. The City of Coeur d'Alene design sheet rates weathering as severe, so every membrane, flashing and drain here works through hard freeze and thaw each year. The drain you skip in October is the ponding you pay for in March.
We run scheduled visits on commercial roofs: two walks a year, a written list after each, and a price on every item. The owner or the GC decides what gets done and when.
The Call: Two Visits, Fall and Spring
One visit a year is not a program. It is an inspection with a hopeful name. The fall visit happens before the first snow and clears what will cause trouble: drains, scuppers, gutters, debris against parapets and loose edge metal. The spring visit happens after the thaw and finds what winter did. Those are the two moments when a small problem is visible and cheap.
Each visit has a hold point. We do not leave a roof with a clogged drain or an open flashing. Minor items get fixed on the spot at the unit price in the program. Larger items get written up with a price and a recommended date. Nothing sits on a list without a number next to it.
The first walk on a roof with no history takes longer, because we build the baseline: a roof plan, a drain count, a penetration list and a set of dated photographs. Every later visit is shorter and cheaper because it starts from that file. A GC bidding a building turnover can ask for the baseline as its own line, since it is the document the owner will want in hand when a lender, a buyer or an insurer asks about the roof.
What It Costs: Unit Prices, Not Surprises
A program is priced as a base visit plus unit prices for the common repairs. A drain cleaning, a fastener replacement, a length of sealant, a boot replacement, a patch at a seam. The owner sees the price list before the first walk and can compare it to the cost of a leak call. A GC carrying roof maintenance in a turnover package can carry the base visit as one line item and the unit prices as an allowance.
The money that matters is the money not spent. Wet insulation is the expensive finding on a commercial roof, because it means tear-off beyond the membrane. Catching a seam that is letting water in during the spring walk costs a small repair. Missing it for two winters costs deck moisture, wet board and a replacement scope with a bigger area. Our infrared moisture survey backs up the walk when we suspect trapped water.
What the Code Sheet Says: Snow Is the Test
Snow weight is not a fixed number. The city's roof snow guidance notes that saturated snow is roughly 20 pounds per cubic foot and that water content swings between about 1 percent and 33 percent, which means equal depths can weigh very differently. A wet foot and a half on a flat roof is a load the structure has to carry, and in a thaw it arrives all at once.
That is why a maintenance walk looks at snow behavior first. We find the drift pockets behind parapets and rooftop units, the drains that serve them and the edge metal that holds the membrane at the perimeter. Post Falls averages about 59 inches a year, and the snow gets heavier to the east: Kellogg averages 52 inches, Wallace about 76 and Mullan more than 100. A building in the Silver Valley needs its first walk earlier than one on the prairie. The cost logic follows the snow: the heavier the load, the more a clogged drain or a loose edge costs, so the program spends its first dollars where the snow lands. Hecla Mining is headquartered in Coeur d'Alene and operates the Lucky Friday mine in the Silver Valley, and a building out there answers to the heavier snow numbers above.
Where It Fails First: Drains, Edges, Penetrations
The first failures are the same on almost every roof. A roof drain clogged with grit sends water across the field. An edge metal fastener backs out and the wind finds the gap. After a windstorm like the one in November 2015, perimeter fastening is the first thing we recheck. A boot around a pipe cracks in the cold and drips into a ceiling.
We check edge metal and gutters, skylights and penetration flashing, rooftop equipment curbs, seams and the surface of the membrane. The tilt-up warehouses and flex buildings at Riverbend Commerce Park have large flat roofs with many rooftop units, and every unit is a curb to check. A medical building near Kootenai Health or a classroom wing at North Idaho College has a different mix, with fewer units and more roof-to-wall transitions.
Alternates: What Else Can Ride With the Program
A base program can carry bid alternates. A drone survey in the first year to set the baseline, an infrared scan every few years, snow guard additions over entries, heat cable at problem scuppers, and a coating plan for roofs that are sound but weathering. Each is a separate line, so the owner picks what stays in.
For roofs near the end of life, the program turns into a capital plan. We keep the same records and give the owner a firm date range for replacement, which feeds a budget instead of an emergency. A coating restoration can extend a sound roof by years at a fraction of the cost of replacement, and the maintenance record is the proof that the roof qualifies.
Closeout: The Record After Every Visit
After each walk, the owner gets a short report: photos of every drain, penetration and finding, a list of what was fixed, a list of what was not, and a price on every open item. The next visit starts from that list. Over a few seasons it shows which drains clog fastest and which seams keep opening.
That record matters at sale, at refinance and when an insurer asks about condition. It also answers the warranty question: a manufacturer wants to see that the roof was maintained. A GC taking over a building with no roof file starts blind, so we build the file as the program runs. When a storm hits, the same record supports storm damage repair and any claim that follows.
Commercial Roofing Questions
How often should a program visit a roof?
Twice a year: fall before snow and spring after the thaw. Add a visit after any major windstorm or hail event.
What does a visit include?
Drain and scupper cleaning, edge metal and fastener check, seam and flashing inspection, penetration and curb check, photos and a written list with prices.
Does a program keep my warranty valid?
It helps. Most manufacturers want evidence of maintenance. Our records show dates, findings and fixes. Check the specific terms of your warranty.
Can a GC include this in a turnover package?
Yes. We price the base visit and unit repairs as separate lines so the GC can carry them as a line item and an allowance.
Is a program worth it on a new roof?
Yes. Early walks catch misplaced fasteners and unsealed curbs before the first winter. Fixing those costs little, and the record starts clean.
