A new roof in Moscow is priced from the roof itself. Area and pitch set the material and labor, layers and decking set how much hidden work sits under the covering, and snow and ice detailing sets how much eave and valley work is needed. Access and the permit come next. A technician confirms the figure on site.
Key takeaways
- Roof area is measured in squares, and a steeper pitch makes every one of those squares slower and more careful work.
- Old layers that have to come off add labor and disposal to the job before the new covering goes on.
- Soft or rotted decking is only visible once the old covering is open, so a quote can change after the tear-off.
- Eave ice and snow drifting into valleys call for more detailing than a plain run of covering, and that detailing belongs in the price.
- Pullman's published design criteria require ice barrier underlayment, and on the Moscow side the Building Safety Division confirms what applies to an address.
- A house on a hillside lot can need the truck and dumpster placed farther away, and that distance changes the labor.
What does a crew measure before it quotes?
A crew starts with the roof's area, its pitch and the number of planes it has. Those three numbers set most of the material and most of the labor.
Area is counted in squares, the unit roofers use for roofing material. A simple gable roof has two planes, while a hip or a cross-gable roof has more, and every valley and hip adds cutting and flashing. Pitch matters because a steep roof is slower and more careful work than a low one, and the crew has to work it safely. Walkability belongs in the same picture, because how safely people can stand on the surface shapes how many hours the job takes.
Most of these numbers come from a visit rather than a photograph. A technician walks the roof where it is safe to do so, checks the eaves and valleys, and looks at the chimney and every penetration through the covering. The result is a count of what is there, not an estimate built from the street. If you want to prepare, note how many roof planes you can see and where a valley or dormer meets the main slope, because those junctions are where a scope tends to grow.
How do layers and decking change the price?
Every layer of covering already on the roof adds removal work and disposal. The deck under it decides how much of the job stays hidden until the tear-off starts.
A roof can carry one layer or several. Whether an old covering can stay in place depends on its condition and on what the building department allows at your address, so it is a question to settle before the quote is final. Removing old layers takes labor and hauls material away. It also changes the nails, the flashing and the drip edge the new covering needs, because the old work is no longer there to build on.
The deck is the part nobody sees until it is exposed. Soft or rotted sheathing has to be cut out and replaced, and that is the reason a quote can move after the tear-off. Ask for the deck condition to be written into the scope, and ask how a change to the deck would be priced. A written answer to that question is worth asking for before you sign anything. If the deck is exposed and the wood is sound, the scope should say so in plain terms, so you know the question was answered.
Why does Palouse snow add to the detailing?
Snow that sits on the roof, thaws and refreezes at the eaves builds ice that can back water under the covering. Fixing that means more detailing at the eaves, valleys and walls, and that work is part of the price.
Ice forms at the eave when the upper roof is above freezing and the lower edge is below it. The University of Minnesota Extension describes that mechanism for ice dams, and the water behind a dam can leak into walls, ceilings and insulation. A quote for a Palouse roof should account for the eave and valley detail that keeps meltwater moving, rather than a plain run of shingles. If the attic is also leaking heat, the roof work alone will not stop the dam, which is why the attic side is part of the estimate too. More on that approach is in the ice dam prevention service.
Underlayment is the piece people ask about most. Pullman's published design criteria list ice barrier underlayment as required, which is the clearest local rule on the Palouse. On the Idaho side the requirement depends on the adopted code and on the address, so the Moscow Building Safety Division is the place to confirm it before the scope is settled. Snow drifting into valleys and against parapets adds load and detail as well, and the building official reads that from the drawings and the site.
How do the hills and the lot change the job?
Access sets how close a truck, a dumpster and a material delivery can get to the house. On a steep lot that distance adds labor, and it can change the schedule.
Moscow has hilly ground, and its north-west section includes the Fort Russell Historic District, a National Register area of 116 structures on sloping residential streets. A truck that can park at the curb makes the work simpler than one that has to unload and carry material up a grade. The same logic applies to debris. A dumpster placed far from the house means more hauling by hand, and that time shows up in the price. Ask the technician to note the access on the scope itself, because a steep approach is easy to forget once the work is booked.
Crews also look at how the roof edge meets the ground. A tall eave, a steep drop to a walkway, or a porch roof tucked under a main roof all change how material is hoisted and how the work is protected. Describe the house, the lot and the entry points when you call. A technician can tell you what the access will mean for the job before anyone is booked for a visit to the site.
Does a rental or a student house change the schedule?
A landlord's quote depends on tenant access and on when the work can be scheduled around the household. Moscow's student calendar and the Palouse winter both shape that timing.
About 40 percent of Moscow's housing is owner-occupied, according to the Census Bureau's QuickFacts for 2020 to 2024, against about 59 percent across Latah County. Moscow is also a university town, home to the University of Idaho, which has roughly 11,000 students on its Moscow campus. Many of the roofs inside the city therefore belong to landlords, and roofing there is a scheduling decision as much as a building one.
Work on an occupied rental needs tenant access, a plan for noise and parked cars, and a clear window that does not cut across the academic year. Winter adds a second constraint. Depending on the roof and the weather, the job may need a tarp until it can be finished, and that tarp is a separate line on the quote. Ask whether the tarp is included, what it costs in visits, and who removes it.
What else gets priced with the roof?
Anything that meets the roof at a joint is priced along with it. Chimneys, sidewalls, skylights, gutters and the attic work that goes with an ice dam fix are the usual additions.
Flashing sits where two surfaces meet, so it is the first thing a crew checks when the covering comes off. Counter-flashing at a chimney, step flashing along a sidewall and the curb around a skylight all need attention whenever the roof is re-covered. Rebuilding that detail is quick to describe and slower to do well, and it is worth writing each joint into the scope so you can see what was included.
Attic ventilation and air sealing are part of an ice dam fix, not extras to it. Warm air leaking from the house into the attic melts snow from below, and the insulation and vent work reduce that heat loss. Gutters and fascia are often in the same condition as the covering, and they are easier to repair while the work is already underway. Ask the technician to note them separately, so the scope shows what changed and what did not.
How do I get a firm number?
A firm figure comes from an on-site visit, a written scope and the permit details for your address. Nothing on this page replaces those three steps.
Start by describing the roof in plain terms: the age of the covering as far as you know it, how many layers you think are on, whether there have been leaks, and whether the house sits on the Idaho or the Washington side of the state line. Those answers shape the scope before anyone climbs a ladder, and they make a visit more productive for both sides. Photographs of the roof, the eaves and the attic are useful too, and they give the technician a starting point before the visit.
Moscow handles reroof permits through the Building Safety Division in Community Development, which takes permit questions at (208) 883-7022 and runs applications through its online permit portal. A technician can explain what the permit covers at your address. Ask for the scope in writing, with the deck condition, the detailing and the access noted, so you can compare it with other quotes on the same terms. Read the full roof inspection service page for what a visit covers. (833) 751-2102
Frequently asked questions
Can you give me a price per square?
No dollar figure for roofing work is published on this site, and this page will not guess one. The reliable number is the one in a written scope after a technician has seen the roof. The variables that move it are the ones described above: area, pitch, layers, decking, detailing, access and the permit.
Does the state line change what I pay?
It can change what the work requires. A house on the Washington side of the line is contracted under Washington registration rules, and an Idaho registration does not authorize work there. The scope and the paperwork can differ even when the roof looks the same from the street.
Why does the quote wait for a visit?
Layers, decking and flashing stay hidden until the roof is opened or walked. A quote built from the street can only guess at them. A visit lets the technician count the planes, check the eaves and see what the access will be, and that makes the written scope more useful to you.
Can I get a quote by phone?
You can call the line at any hour and describe the roof. A technician will take the details and schedule a visit when one is free. Treat any figure given on the phone as a starting point, because the firm number depends on what the roof shows once someone is on it.
Is winter a bad time to replace a roof?
Winter can delay the work, because the roof may need to be finished when the weather allows. If the covering cannot be completed before snow arrives, a tarp can hold the house until a crew can return. Ask what the plan is before you agree to a date.
What should a written scope include?
A useful scope lists the roof area and pitch, the number of layers to be removed, the deck condition and how any deck repair is priced, the eave and valley detail, the flashing at each joint, the ventilation work and the cleanup. It also names the permit and the access plan. A scope that leaves those items out makes the comparison with other quotes harder to read.
