Quick answer: Exterior remodeling in the Treasure Valley generally runs $8,000–$20,000 for whole-home windows, $10,000–$32,000 for siding, and $9,000–$18,000 for an asphalt roof. Exterior work is also the smartest money in remodeling right now: 8 of the 10 highest-ROI projects are exterior replacements, and fiber-cement siding recoups roughly 114% of its cost at resale (Remodeling Cost vs. Value, 2025).
Key Takeaways
- Ballpark ranges: windows $8K–$20K, siding $10K–$32K, roofing $9K–$18K.

- Fiber-cement siding recoups ~114%; vinyl siding ~97% — the highest-returning projects tracked.
- Fiber cement handles Idaho’s freeze-thaw better than vinyl, which can grow brittle in sustained cold.
- Boise foothills homes in Wildland-Urban Interface (WUI) zones must use ignition-resistant cladding (City of Boise WUI Overlay).
How much does exterior remodeling cost in Idaho?
Exterior remodeling costs in the Treasure Valley depend on which project you tackle: replacement windows run about $8,000–$20,000 for a whole home, new siding $10,000–$32,000, and an asphalt roof $9,000–$18,000. Most homeowners phase these projects over several years, starting with whatever is failing first.
The good news: exterior projects consistently return more at resale than interior remodels. In the latest data, 8 of the 10 highest-ROI remodeling projects are exterior replacements — siding, doors, windows, and roofing — because curb appeal drives buyer decisions (Remodeling Cost vs. Value, 2025).
Exterior remodeling cost by project
| Project | Typical total cost |
|---|---|
| Windows (whole home) | $8,000 – $20,000 |
| Siding | $10,000 – $32,000 |
| Roof (asphalt) | $9,000 – $18,000 |
How much do replacement windows cost?
Replacement windows vary widely by size and material, but vinyl — the most popular choice for its price and low maintenance — runs roughly $650 to $1,300 per window installed (Angi, 2026). Wood, fiberglass, and specialty shapes cost more.
For a whole home, that adds up fast: replacing 10–15 windows commonly lands between $8,000 and $20,000 installed (Angi, 2026). In Idaho’s climate — hot summers, cold winters — energy-efficient windows with low-E, gas-filled double panes pay you back in lower heating and cooling bills.
How much does new siding cost — and what’s best for Idaho?
New siding costs about $6 to $13 per square foot installed, or roughly $10,000 to $32,000 for a typical 2,500-square-foot home (This Old House, 2026). Vinyl is the most affordable option; fiber cement (James Hardie-type board) sits at the premium end but is often the better long-term value in the Treasure Valley.
Here’s the Idaho-specific insight: our freeze-thaw cycles are hard on cladding. Vinyl can become brittle and crack in sustained cold, while fiber cement resists moisture, holds paint longer, and stands up to freeze-thaw and fire.
Wildfire rules you can’t skip: homes in Boise’s Wildland-Urban Interface (WUI) zones — including foothills fire-hazard areas — must use ignition-resistant construction under Boise’s Wildland-Urban Interface (WUI) Fire Code (Boise City Code § 11-02-07.3.H), with foothills fire-hazard areas held to the stricter Class 1 (IR1) standard (City of Boise, WUI Overlay). If your home is in a foothills WUI area, non-combustible cladding like fiber cement isn’t just smart — it may be required.
How much does a roof replacement cost in Boise?
A roof replacement in the Boise area costs $4 to $11 per square foot, with most asphalt-shingle roofs landing between $9,000 and $18,000 (Angi, 2026). Basic 3-tab shingles run about $4.50 to $7.50 per square foot installed, while more durable architectural (dimensional) shingles run $6 to $9 (Angi, 2026).
For Idaho homes, architectural shingles are usually worth the upgrade: they handle wind, snow load, and intense summer UV better than 3-tab, and they carry longer warranties. If your roof is more than 20 years old, curling, or losing granules, replacing it is the first exterior project to prioritize.
Which exterior upgrade has the best ROI?
Exterior replacements dominate remodeling ROI, and siding leads the pack. In the latest Cost vs. Value data, fiber-cement siding recoups about 114% of its cost at resale — meaning it adds more value than it costs — and vinyl siding about 97%. Roofing and window replacement recoup roughly 65–72% (Remodeling Cost vs. Value, 2025).
| Project | Cost recouped |
|---|---|
| Fiber-cement siding | ~114% |
| Vinyl siding | ~97% |
| Roofing (asphalt) | ~68% |
| Window replacement | ~68% |
What’s the best material for Idaho’s climate?
The Treasure Valley’s mix of freeze-thaw winters, dry heat, and strong UV rewards durable materials. For siding, fiber cement is the standout — it resists moisture, cracking, and fire, and holds paint far longer than vinyl. For roofing, architectural asphalt shingles balance cost and durability. For windows, energy-efficient double-pane units with low-E coatings cut heating and cooling costs year-round.
If your home sits in a foothills WUI zone, material choice narrows further: ignition-resistant cladding and Class-A roofing assemblies help meet fire code and protect your home during wildfire season.
| Category | Share of budget |
|---|---|
| Siding | 35% |
| Roofing | 30% |
| Windows | 25% |
| Trim, gutters & labor | 10% |
Do you need a permit for exterior work in Boise?
Yes — most structural exterior work in Boise requires a building permit, including roof replacements and siding jobs that alter sheathing or structure (City of Boise). On top of standard permits, homes in Wildland-Urban Interface (WUI) zones must meet ignition-resistant construction requirements under Boise’s WUI Fire Code.
A licensed contractor pulls the permits, meets code (including WUI requirements where they apply), and schedules inspections. For current permit-fee figures, the City of Boise Planning & Development Services line is (208) 608-7070.
Which exterior project should you do first?
When budgets are phased, prioritize by failure risk first, then value. Start with the roof if it’s aging or leaking — water damage undermines everything below it. Next, tackle siding, which protects your home’s envelope and delivers the best resale return. Finally, upgrade windows for comfort and energy savings.
This order protects your home from the most costly damage first while sequencing the highest-ROI work (siding) before the lower-ROI comfort upgrades (windows).
Frequently asked questions
How much does it cost to replace all the windows in a house? Replacing every window in a typical home costs about $8,000 to $20,000 installed, based on 10–15 vinyl windows at roughly $650 to $1,300 each. Larger or specialty windows cost more.
Is fiber cement or vinyl siding better for Idaho? Fiber cement is generally better for Idaho’s freeze-thaw climate — it resists cracking, moisture, and fire, and holds paint longer. Vinyl costs less but can grow brittle in sustained cold. In foothills WUI zones, ignition-resistant cladding like fiber cement may be required.
Does new siding increase home value? Yes — significantly. Fiber-cement siding recoups about 114% of its cost at resale and vinyl siding about 97%, making siding the highest-ROI remodeling project tracked in the 2025 Cost vs. Value Report.
How much does a new roof cost in Boise? A new asphalt-shingle roof in the Boise area typically costs $9,000 to $18,000, or $4 to $11 per square foot. Architectural shingles ($6–$9/sq ft) cost more than 3-tab ($4.50–$7.50/sq ft) but last longer.
Do I need a permit to replace siding or a roof? Usually yes. Roof replacements and structural siding work in Boise require a building permit, and homes in WUI fire zones must meet ignition-resistant construction standards.
