A roof replacement in the Portland–Vancouver area costs between $12,000 and $30,000+ in 2026, with most standard single-family homes landing between $14,000 and $20,000 for architectural asphalt shingles with a full tear-off. Installed asphalt work generally runs $7–$9 per square foot, with Clark County labor a modest premium over Portland. Steep, complex, or premium-material roofs — and hidden decking repairs — push the number higher; small, simple roofs come in lower.
Replacing your roof is one of the largest investments you’ll make in your home — and one of the most confusing. It’s normal to get three estimates for the same house that vary by ten thousand dollars or more, with little explanation of why. After installing roofs across Portland and Southwest Washington since 2018, we’ve seen exactly where those differences come from. This guide gives you honest, local September 2026 pricing from our own estimate and install data, explains what actually drives the cost, and shows you how to tell a fair bid from a bad one.
Roof replacement cost by home size (2026)
For a typical single-family home with architectural asphalt shingles and a standard tear-off, most homeowners in our area invest somewhere in this range:
| Home size (footprint) | Typical 2026 cost range |
|---|---|
| 1,000–1,500 sq ft | $10,000 – $14,000 |
| 1,500–2,000 sq ft | $13,000 – $18,000 |
| 2,000–2,500 sq ft | $16,000 – $22,000 |
| 2,500–3,500 sq ft | $20,000 – $30,000+ |
Ranges assume a full tear-off and a quality replacement with proper ventilation — not the cheapest possible job. Based on Jobin Roofing estimates and installs across Clark County and the Portland metro.
Roof replacement cost by material (installed, per sq ft)
| Material | Installed cost per sq ft | Notes |
|---|---|---|
| Architectural asphalt shingles | $7.00 – $9.00 | The most common choice in our area — the ranges above assume this system |
| Designer / premium shingles | $10.00 – $14.00 | Heavier profile, longer warranties, distinctive look |
| Standing-seam metal | $11.00 – $18.00 | Typical full projects start around $19,000–$25,000+; 40–50 year lifespan |
Standard 3-tab shingles still exist at the bottom of the market, but they’re increasingly rare here — architectural shingles look better, last longer in our climate, and carry stronger warranties for a modest difference in price. Metal is the fastest-growing choice in the Northwest for homeowners planning to stay 15+ years.
What actually drives the price
Once you understand these five factors, most of the confusion around roofing quotes disappears.
1. Roof size and complexity
Roofers price by the “square” (a 10×10 ft area, or 100 sq ft), not by your home’s living space. A simple gable roof with one or two planes costs far less to install than a roof with multiple dormers, valleys, steep pitch, and hips — those features add labor, materials, and safety requirements. Two homes with the same square footage can differ by thousands based on roof shape alone.
2. Material and system
Standard 3-tab shingles are the most affordable but increasingly rare. Architectural (dimensional) shingles are the most common choice in our area — they look better, last longer, and carry stronger warranties. Premium designer shingles and metal systems cost more upfront but extend the lifespan significantly. The right choice depends on how long you plan to stay in the home and the look you want.
3. Tear-off vs. overlay
A full tear-off removes the old roofing down to the decking so everything can be inspected and rebuilt correctly. An overlay (installing new shingles over old) is cheaper upfront but hides problems, adds weight, and usually shortens the life of the new roof. In the wet Pacific Northwest, we almost always recommend a full tear-off replacement — it’s the difference between a roof that lasts and one that fails early.
4. Ventilation and decking
What’s under the shingles matters as much as the shingles. Poor attic ventilation traps moisture and heat and dramatically shortens roof life — a real issue in our damp climate. And once the old roof comes off, it’s common to find soft or rotted plywood decking that must be replaced (typically $85–$125 per sheet). Reputable estimates account for the possibility of decking repair; suspiciously low bids often leave it out, then add it as a “surprise” mid-project.
5. Installation quality (the biggest variable)
This is where estimates differ the most and where homeowners get burned. A lower bid often means a faster crew, fewer details done right, cheaper underlayment and flashing, and a thinner warranty. Roofing isn’t just materials — it’s workmanship that has to stand up to PNW rain for 25+ years. The cheapest bid is rarely the best value, and the most expensive isn’t automatically the best either. What you’re paying for is a crew that does it right the first time.
Why one roof gets quotes of $12K, $18K, and $25K
It’s genuinely common to get quotes this far apart for the same home. The spread almost always comes down to:
- Material grade — basic vs. architectural vs. premium shingles.
- Scope — whether tear-off, decking repair, ventilation, flashing, and gutters are included or left out.
- Labor standards — an experienced, properly insured crew vs. the cheapest available labor.
- Warranty — a manufacturer-backed system warranty plus a real workmanship warranty vs. little to none.
- Corners cut — the low bid often becomes the high bid once the “extras” appear.
The fix is to compare bids line by line, not just bottom-line. Ask each contractor exactly what’s included, what shingle and underlayment they’re using, and what their workmanship warranty covers. A good roofer will welcome the question.
How much does it cost to replace a roof on a 2,000 sq ft home?
In the Portland–Vancouver area, replacing the roof on a 2,000 square foot home typically costs $15,000 to $22,000 in 2026 with architectural asphalt shingles and a full tear-off. The exact number depends on pitch and complexity more than the footprint itself — a steep roof with dormers and valleys on a 2,000 sq ft home can cost more than a simple gable roof on a larger one. Remember that the roof’s surface area is larger than the home’s footprint, especially on steeper pitches.
What is the 25% rule for roofing?
The “25% rule” is a common guideline for the repair-vs-replace decision: when more than about a quarter of the roof is damaged or worn — or when repair costs approach a quarter of the replacement cost — full replacement is usually the smarter investment. Patching a roof that’s already failing across large sections means paying twice: once for repairs that buy a year or two, then again for the replacement. Below that threshold, a well-done repair on an otherwise healthy roof is often the right call, and an honest contractor will tell you which side of the line you’re on.
Should a 20-year-old roof be replaced?
In the Pacific Northwest, usually yes — or at minimum it’s time for a real inspection and a plan. Architectural asphalt shingles are rated for 25–30 years in ideal conditions, but our climate is not ideal conditions: months of rain, moss growth, and debris from tall firs age roofs faster here than in dry climates. At 20 years, look for curling or missing shingles, heavy granule loss in the gutters, moss that keeps returning, and any interior staining. Even if it isn’t leaking yet, a 20-year-old roof in Clark County or Portland is near the end of its reliable life — replacing it on your schedule beats replacing it during a January atmospheric river.
What is the average cost to replace a roof in Washington State?
Statewide, asphalt roof replacements in Washington mostly fall in the $10,000–$30,000 range depending on home size, pitch, and material — in line with the local table above. Southwest Washington and the Clark County market tend to run a modest premium over rural parts of the state, reflecting labor costs in the Portland metro area. Every re-roof in Clark County requires a permit, which a legitimate contractor pulls as part of the job.
Pacific Northwest factors that affect your roof
Roofs here work harder than in most of the country. Months of rain, persistent moisture, moss and algae growth, moss-holding shade from tall firs, and the occasional atmospheric-river storm all test a roof’s weakest points. That’s why proper underlayment, correct flashing details, adequate ventilation, and quality installation matter even more here than they do in drier climates. A roof that would be “fine” in Arizona can fail early in Clark County.
How to get an exact price for your home
Every roof is different, so the only way to know your real number is an inspection. A thorough roofer will measure your roof, check the decking and ventilation, look at flashing and penetrations, and walk you through your options with clear, written pricing.
At Jobin Roofing, that’s exactly what we do — a clear, no-pressure estimate, honest recommendations (including when a repair makes more sense than a replacement), and a detailed breakdown so you understand every line. No pressure, no pricing games.

How much does a new roof cost in Vancouver, WA?
Most Vancouver homeowners invest between $14,000 and $20,000 for a standard architectural-shingle replacement with a full tear-off in 2026, within a full local range of $12,000–$30,000+. Larger, steeper, or more complex roofs — or those needing decking repair — run higher. The only way to get an exact number is an on-site inspection that measures your roof and checks the decking and ventilation.
How much does a roof cost in Portland, OR?
Pricing in Portland is similar to Vancouver, generally $14,000–$20,000 for a typical home, with permits, home design, and material choice affecting the final number. Steep or complex roofs and premium materials push the figure up; simple, smaller roofs can land lower.
Why are roofing estimates so different for the same house?
Differences in material grade, scope of work (tear-off, decking, ventilation), labor quality, and warranty coverage drive most of the spread. Compare bids line by line, not just by the total — and ask each contractor what shingle and underlayment they use and what their workmanship warranty covers. A low bid often becomes the high bid once the “extras” appear mid-project.
Is it cheaper to overlay than tear off?
An overlay is cheaper upfront, but in the wet PNW it usually shortens the new roof’s life and can hide existing damage like rotted decking. A full tear-off lets the crew inspect and rebuild the roof correctly, and it’s almost always the better long-term value here. We generally recommend tear-off replacement for that reason.
Can you estimate my roof cost without seeing it?
We can give you a ballpark range from your home’s size and roof type, but an accurate, guaranteed price requires an on-site inspection of your decking, ventilation, and roof complexity. Two homes with identical square footage can differ by thousands based on roof shape alone, which is why an inspection is the only way to a real number.
Do you offer financing?
Yes — we offer financing options so you can spread the investment into manageable monthly payments. Ask us during your estimate. If your roof damage came from a covered event like a storm, an insurance claim may also offset much of the cost.
