"How much does a new roof cost?" is the first question almost every Seattle homeowner asks us — and it's the one most roofing websites answer with vague national averages that have nothing to do with what you'll actually pay in the Pacific Northwest.
We're going to fix that. After 20+ years in the Seattle market, we know exactly what roof replacement cost in Seattle looks like in 2026: what drives the number up, what drives it down, and how to tell a fair quote from one that will cost you later.
This guide gives you real cost tables by material and by roof size, an honest breakdown of the seven factors that move your price, and straight answers to the ten questions homeowners ask us most. The only thing it won't give you is your exact price — because the only way to get that is a proper on-site inspection, and we'll explain why that matters at the end.
Whether you're budgeting for a planned replacement or responding to a leak that's no longer ignorable, this is what roof replacement cost in Seattle actually looks like right now.
For a typical single-family home in Seattle, here's the real landscape:
| Roofing Material | Installed Cost per Sq Ft | Typical Seattle Home (~1,700 sq ft roof) | Expected Lifespan | |---|---|---|---| | Architectural asphalt shingles | $9–$15 | $11,000–$18,000 | 20–25 yrs (Seattle) | | Premium / designer shingles | $13–$18 | $16,000–$25,000 | 25–35 yrs | | Standing-seam metal | $15–$24 | $18,000–$35,000 | 40–70 yrs | | Cedar shake | $18–$30 | $22,000–$40,000 | 25–40 yrs | | Flat / low-slope (TPO, PVC) | $10–$18 | $12,000–$25,000 | 20–30 yrs |
These are all-in costs — tear-off and disposal of the old roof, materials, labor, underlayment, flashing, and cleanup. They do not include deck repairs if rotted sheathing is found, or extras like new gutters or skylights.
Most Seattle homes with architectural asphalt shingles land somewhere in the **$11,000–$18,000** range. If you've received a bid well outside this range in either direction, it's worth investigating before you sign anything.
The national average for roof replacement is approximately $10,900 (Angi, 2026 data). Seattle homeowners routinely pay 10–25% more. The gap exists for concrete reasons:
If a Seattle contractor bids at national-average prices without explaining why, be cautious. Cutting corners on prep, materials, or crew experience is the most common explanation for a suspiciously low number.

Roofing is priced by the **"square"** — a 10×10 foot area, or 100 square feet of roof surface. Roof area is measured on the slope, not the footprint of your house. A 2,000 sq ft house with a steep pitch will have significantly more roof surface area than a 2,000 sq ft rambler.
Here's what Seattle homeowners typically pay based on roof size for the two most common material choices:
| Roof Size (slope area) | Architectural Asphalt Shingles | Standing-Seam Metal | |---|---|---| | 1,000 sq ft | $6,500–$11,000 | $11,000–$18,000 | | 1,500 sq ft | $9,500–$16,500 | $16,000–$27,000 | | 2,000 sq ft | $12,500–$22,000 | $21,000–$36,000 | | 2,500 sq ft | $16,000–$27,500 | $26,000–$45,000 | | 3,000 sq ft | $19,000–$33,000 | $31,000–$54,000 |
**Pitch matters.** A roof with a pitch of 8/12 or steeper is slower and more dangerous to work on — expect a labor premium of 25–50% over a low-slope or walkable roof at the same square footage. If your house has a tall, steep Craftsman roofline, your cost per square foot will be higher than these ranges suggest.
These are ranges, not quotes. Where you land within the range depends on the seven factors below.
More roof area means more material and more labor — straightforward. Pitch is where people are sometimes surprised. A 2,000 sq ft house with a 10/12 pitch costs meaningfully more to reroof than a 2,000 sq ft house with a 4/12 pitch, even if the contractor's per-square rate is identical. Roofing steep pitches is physically demanding, slow work that requires additional safety equipment.
This is the single biggest lever on your price. Asphalt shingles and metal roofing can differ by $8–$15 per square foot installed — more than $10,000 on a typical Seattle home. The right choice depends on your budget, how long you plan to stay in the house, and your tolerance for ongoing maintenance. We cover this fully in the material section below.
Before a new roof goes on, the old one comes off. Tear-off and disposal typically costs **$1,500–$4,000** depending on roof size and number of existing shingle layers. In Seattle, we almost always recommend a full tear-off over an overlay (installing new shingles directly on top of old ones), for three reasons:
If a contractor proposes an overlay without explaining why your situation is an exception, that's a red flag.
Once the old roof comes off, we see the wood deck underneath — and in Seattle, that's where surprises happen. Our wet climate is hard on roof sheathing. Moisture-driven rot is especially common around valleys, chimneys, skylights, and eaves where ice-and-water shield may have failed over time.
Deck repairs typically run **$3–$6 per square foot** of affected area, or roughly $75–$150 per 4×8 sheet of replacement plywood or OSB. On most older Seattle homes, we budget **$500–$2,500** for deck repairs as a reasonable contingency. For roofs over 20 years old or with a history of leaks, budget higher.
A transparent contractor will tell you upfront that deck repairs are possible and explain the per-sheet cost — not wait until your roof is half off to spring an unexpected $5,000 bill on you. A [professional roof inspection](/services/inspection) before signing your contract can uncover known problem areas and help you set a realistic budget.
A simple gable roof is far cheaper to replace per square than a cut-up roofline with dormers, multiple valleys, chimneys, and skylights. Every penetration and transition point requires careful flashing — and more flashing means more time and material. In rough terms:
Moss removal before a new roof is not optional — it's a warranty requirement for most shingle manufacturers, and it's the right thing to do for the longevity of your new installation. Active moss must be treated and removed before new shingles go down. Plan for **$200–$600** in moss preparation depending on coverage.
After installation, zinc or copper ridge strips help prevent moss re-growth. These cost **$200–$500** and dramatically reduce the maintenance burden in the years ahead. We include this recommendation in every asphalt shingle installation we do.
Ice-and-water shield at eaves and valleys provides an extra waterproofing layer critical in Seattle's climate. Most quality installations include this as standard; confirm it's in your quote.
Seattle permits are not required for most standard single-family residential re-roofing (shingles only, no structural changes). The [Seattle Department of Construction & Inspections](https://www.seattle.gov/sdci) provides permit guidance for edge cases. Where permits are needed, expect **$250–$500**.
Debris disposal — hauling away all the old roofing — runs **$500–$1,500** depending on roof size and layers removed. This should be included in your written quote. If it isn't listed, ask.
Choosing the right material for Seattle's climate is just as important as getting the right price. Here's the honest breakdown.
Architectural (also called "dimensional" or "laminated") asphalt shingles are the most popular choice on Seattle homes, and for good reason: they offer the best balance of upfront cost, appearance, and performance for the Pacific Northwest.
If choosing asphalt, invest in algae-resistant shingles — look for products with copper granules built in, such as those from [GAF](https://www.gaf.com/en-us/roofing-products)'s Timberline CS line or IKO's Cambridge Algae Resistant series. They cost slightly more upfront but dramatically reduce moss and algae growth — a major maintenance advantage in Seattle. We're a GAF Certified Contractor and [IKO ROOFPRO Advantage certified](https://www.iko.com/na/for-contractors/roofpro/) installer.
For a deeper comparison, read our guide on [asphalt vs. metal roofing in Seattle](/blog/asphalt-vs-metal-roofing-seattle).
Standing-seam metal is the premium choice for homeowners who plan to stay long-term and want a roof they'll likely never replace again.
Metal is inherently resistant to moss and algae, sheds Seattle's rain efficiently, and handles our freeze-thaw cycles far better than asphalt. The tradeoff is a higher upfront cost and the need for a contractor with genuine metal roofing expertise — not every asphalt crew is qualified to install standing-seam correctly.
Cedar shake has a beautiful, classic look that's right at home on a Pacific Northwest Craftsman or Tudor. It's a legitimate option, but Seattle's climate makes the math challenging.
Untreated cedar in Seattle's wet climate will absorb moisture, develop moss and algae, and begin to rot within 5–10 years. If you choose cedar, choose a contractor with demonstrated cedar installation experience and budget seriously for maintenance. Our guide to [roof maintenance in Seattle](/blog/how-to-maintain-your-roof-in-seattle) covers cedar-specific care in detail.
Many mid-century Seattle homes, additions, and commercial buildings have flat or low-slope roofs. These require different systems and different contractor expertise.
TPO and PVC are the most common single-ply systems for Seattle flat roofs. They're heat-welded for seamless coverage and handle our wet climate well when installed correctly.
Upfront cost isn't the whole story. Here's what each major material costs over a 30-year horizon, accounting for potential replacement and maintenance:
| Material | Upfront Cost | Replacements in 30 Yrs | Maintenance (30 yrs) | Total 30-Year Cost | |---|---|---|---|---| | Asphalt shingles | ~$15,000 | 0–1 (~$17,000) | ~$3,000 | $15,000–$35,000 | | Standing-seam metal | ~$25,000 | 0 | ~$500 | ~$25,500 | | Cedar shake | ~$30,000 | 0–1 (~$32,000) | ~$9,000 | $30,000–$71,000 |
Over 30 years, metal roofing frequently costs less than asphalt — despite a $10,000 higher upfront investment. The [National Roofing Contractors Association (NRCA)](https://www.nrca.net/) supports metal's long-term value in moisture-heavy climates. Whether that math works for you depends on how long you plan to own the home.
The all-in cost of a roof replacement is always higher than the headline material-and-labor number. These are the line items that catch people off guard.
Deck repairs are the most common "surprise" in Seattle roof replacements. Rotted sheathing around valleys, chimneys, and eaves is routine on older homes. Budget $500–$2,500 as a contingency and ask your contractor explicitly: "What do you charge per sheet for deck replacement, and will you notify me before doing the work?"
A new roof with failing gutters is a false economy. When gutters pull away from the fascia or lose their slope, water backs up under the eaves and can damage your new installation in the first rainy season. [Gutter replacement and cleaning](/services/gutters) at the same time as a roof replacement saves mobilization costs and guarantees the whole system works together. Plan for **$800–$2,500** for full gutter replacement depending on linear footage and material.
Chimney flashing, valley flashing, and skylight flashing often need replacement during a re-roof — especially on older homes where existing flashing has corroded or failed. Confirm whether flashing replacement is included in your quote, or whether it's an additional cost triggered by field conditions.
In Seattle, ice-and-water shield at eaves and valleys is standard on quality installations. It adds $300–$800 over basic felt underlayment but provides critical extra waterproofing protection that our climate demands. If a low bid omits it, that's one of the places the savings is hiding.
Improper attic ventilation voids most manufacturer warranties on asphalt shingles and causes premature failure by trapping heat and moisture against the deck. If your attic isn't properly balanced with ridge vents and soffit vents, correcting it during a re-roof costs **$500–$1,500** — and protects the warranty on your new shingles. A reputable contractor will flag this during a pre-install walkthrough.
Roofing generates significant debris. Full cleanup and haul-away should be included in your quote — confirm it is. A nail/magnet sweep of your driveway and yard should also be standard; if it's not mentioned, ask.
A $15,000–$25,000 expense isn't in most people's savings account. Here are the realistic options.
Many Seattle roofing companies offer financing through services like Hearth or GreenSky. Promotional rates of 0% APR exist, but read the fine print — many are "deferred interest" products, not true 0% loans. If you don't pay the full balance before the promotional period ends, interest from day one is added retroactively. Know exactly what you're signing.
For homeowners with equity, a HELOC typically offers the lowest interest rate of any financing option. Your home serves as collateral, the rate is variable but usually well below personal loan rates, and you only draw what you need. Apply before you need the roof — approval takes time.
A home equity loan gives you a fixed rate and predictable monthly payments. Good option if you want cost certainty and have sufficient equity. Like a HELOC, your home is collateral.
If you don't have enough equity or don't want to put your home on the line, personal loans are available at higher rates (typically 8–20% APR depending on credit). They work for smaller projects in the $8,000–$15,000 range where the interest cost is manageable. Credit unions often beat banks on rate.
If you're installing an [ENERGY STAR certified roofing product](https://www.energystar.gov/products/roofing_products), you may qualify for the federal Residential Energy Efficiency Tax Credit under Section 25C of the IRS code. Consult your tax advisor for eligibility — requirements have changed in recent years and depend on your specific situation.
The short answer: sometimes — and the details matter enormously.
Homeowners insurance covers roof replacement when damage results from a **covered peril**: windstorm, hail, falling trees, fire, or similar sudden events. In Seattle, wind damage and tree falls during winter storms are the most common covered events. If a windstorm lifts shingles or a tree branch punches through your roof, that's exactly what your insurance is designed for.
Document everything with photos before making any temporary repairs, and get a professional inspection report from a licensed contractor. Our team works with insurance companies directly on [storm damage repair](/services/storm-damage) and knows how to document damage in a way that supports your claim.
For full details on the process, read our guide: [storm and wind damage insurance claims in Seattle](/blog/storm-wind-damage-roof-repair-seattle-insurance-claims).
The most important variable in a roof insurance claim is whether your policy pays **Actual Cash Value (ACV)** or **Replacement Cost Value (RCV)**.
The difference can exceed $10,000. Review your policy or call your agent before you need it. Our [insurance claims page](/insurance) explains how we work with homeowners through the claims process.
Before committing to a full replacement, it's worth confirming that's actually what your roof needs. See our guide to [roof repair cost in Seattle](/blog/roof-repair-cost-seattle) if your roof may only need targeted work.
Replacement is typically the right call when you see:
**Age-based signals:**
**Visible deterioration:**
**Damage pattern:**
**The 15% Rule:** A useful industry guideline — if repairing your current roof would cost more than 15% of a full replacement's price, replacement usually delivers better long-term value. On an $18,000 replacement, that's roughly a $2,700 repair threshold.
A [professional roof inspection](/services/inspection) is the right first step when you're unsure. It answers the repair-or-replace question with real numbers, not guesswork.
Online cost calculators ask for your zip code and approximate square footage and return a number. That number isn't useful for Seattle homeowners. It can't account for:
The only number you can act on comes from a licensed contractor who physically measures the roof and evaluates what's underneath.
A quality written estimate from a Seattle roofing company should include:
If a bid comes in significantly below the ranges in this guide, something is likely missing. Common places contractors cut corners:
Every Seattle roofing contractor you seriously consider should provide:
Our WA State L&I license is **SEATTSR761Q5**. We carry GAF Certified Contractor and IKO ROOFPRO Advantage status, and every project is backed by a **$250K Directorii Elite workmanship guarantee**.

A roof replacement in Seattle typically costs between $9,000 and $35,000+, depending on material and roof size. Most single-family homes with architectural asphalt shingles fall in the $11,000–$18,000 range, while standing-seam metal roofing runs $18,000–$35,000 for the same home. Seattle prices run 10–25% higher than the national average of approximately $10,900 due to higher labor rates ($65–$95/hr), rain-related delays, and the prep required to address moss and algae before installation.
For a 2,000 sq ft roof (measured on the slope, not the house footprint), expect $12,500–$22,000 for architectural asphalt shingles, or $21,000–$36,000 for standing-seam metal. Costs vary based on pitch, number of existing layers, decking condition, and roof complexity. A steep pitch adds 25–50% to labor.
Architectural asphalt shingles are the most affordable option, typically $9–$15 per square foot installed. For most Seattle homes, that's $11,000–$18,000 all-in. Algae-resistant architectural shingles offer the best budget balance for the Pacific Northwest — they cost slightly more than standard shingles but dramatically reduce moss and maintenance costs over the roof's life.
For most single-family and two-family homes in Seattle, you do NOT need a permit when only replacing roofing materials (shingles, underlayment). Permits ARE required if you're replacing structural sheathing or framing, adding insulation that changes the building envelope, or if the property is multi-family with work exceeding 500 sq ft. The [Seattle Department of Construction & Inspections](https://www.seattle.gov/sdci) is the authority on permit requirements. Your contractor should clarify this upfront.
Standing-seam metal roofing lasts longest in Seattle's wet climate — typically 40–70 years with minimal maintenance. Metal is naturally moss-resistant, sheds rain efficiently, and handles our freeze-thaw cycles far better than asphalt or wood. Architectural asphalt shingles with algae-resistant granules last 20–25 years with proper maintenance. Cedar shake can reach 25–40 years but requires consistent annual treatment to resist rot and moss.
Most residential roof replacements take 1–3 days for standard homes. Larger homes or complex rooflines with multiple dormers, skylights, or valleys may take 4–5 days. A quality crew dries in the roof each day to protect the structure — even during multi-day projects in uncertain weather. July through September offers the best working conditions.
July through September is the optimal window: lowest rainfall, adhesives cure properly, and crews work most efficiently. That said, Seattle roofing companies work year-round. A well-managed winter or spring replacement with daily dry-in is a legitimate option, and off-season timing sometimes means better contractor availability.
Insurance covers roof replacement when damage results from a covered peril — windstorm, hail, fallen trees, fire. It does NOT cover normal wear and tear, age-related deterioration, moss or algae damage, or neglected repairs. Whether your policy pays Actual Cash Value (ACV) or Replacement Cost Value (RCV) matters enormously — RCV policies pay significantly more. Review your policy before you need to use it.
In-person inspection only — online calculators can't account for pitch, decking condition, or roof complexity. Get 3–5 written estimates with line-item breakdowns: specific materials (manufacturer and product line), labor, tear-off, disposal, and deck repair contingency. Verify each contractor's WA State L&I license, insurance certificate, and manufacturer certifications before signing.
Options include: contractor financing programs (0%–12% APR; read fine print for deferred interest traps); HELOC (typically best rate, home as collateral); home equity loan (fixed rate, predictable payment); personal loans (higher rate, no collateral required); and potentially federal tax credits under Section 25C for qualifying [ENERGY STAR-rated roofing products](https://www.energystar.gov/products/roofing_products).
Roof replacement cost in Seattle in 2026 ranges from roughly $9,000 for a small home with asphalt shingles to $40,000+ for a large home with standing-seam metal. Most single-family homes in our service area land between **$11,000 and $22,000**. Where you land depends on size, pitch, material, and what we find when the old roof comes off.
