Total Cost Range & Breakdown by Category

The final number depends on three variables: roof size (measured in squares—one square = 100 sq ft), material choice, and your region. On a 20-square roof (2,000 sq ft) with 3-tab asphalt shingles, expect $8,000–$12,000 total in most markets. That breaks down roughly to $4,000–$6,000 in labor, $3,500–$5,000 in materials, and $300–$800 in permits and inspections.

Step up to architectural (dimensional) shingles and you're looking at $10,000–$15,000 total. Metal roofing—which lasts 40+ years versus asphalt's 15–20—runs $15,000–$25,000+. The labor cost per square foot stays consistent ($3–$5 across most residential work), but material cost per square explodes with premium options.

Permits aren't optional negotiating points. Most municipalities require them, and they typically cost $300–$1,200 depending on your county's assessment formula. Skip the permit and you lose roofing manufacturer warranties, void your homeowner's insurance coverage for that work, and create a liability nightmare if someone gets hurt on your property during installation.

Labor Cost Structure: What You're Actually Paying For

Labor runs $40–$65 per square (that's per 100 sq ft) in most U.S. markets, which translates to $3–$5 per sq ft. A 20-square job typically takes 3–5 days for a 2-person crew, though that stretches if you need structural repairs, soffit/fascia replacement, or if the old roof has asbestos shingles (which requires certified abatement—expect an extra $500–$2,000).

Northeast roofing crews—working in New York, Massachusetts, Pennsylvania—charge $55–$65 per square because of higher cost of living, union scales in many areas, and weather delays that eat into schedules. Midwest crews (Ohio, Indiana, Illinois) run $45–$55 per square. The South (Texas, Georgia, Florida) is $35–$50 per square, partly because year-round working season and partly because local wage floors are lower.

Demolition and haul-away cost $1–$2 per square on top of installation labor. If your old roof has multiple layers (common on houses that were re-roofed instead of stripped), add another $500–$1,500. Ventilation work, drip edge installation, and flashing repairs—which separate pros from hacks—add $300–$800 if not bundled into the quoted labor.

Where homeowners get burned: contractors who quote "$40 per square installed" but then charge separately for tear-off ($1.50/sq), haul ($1/sq), and ventilation repairs ($600). That's already $4.50/sq before materials touch the roof.

Materials: Shingles, Underlayment & Hardware

Asphalt shingle bundles—the standard for U.S. residential roofing—cost $35–$50 per bundle wholesale, and you need 3 bundles per square (100 sq ft). That's roughly $100–$150 per square in raw material. A 20-square roof needs about 60 bundles, or $2,100–$3,000 just in shingles. Three-tab shingles run the low end ($90–$120/sq installed); architectural shingles hit $130–$180/sq installed; premium impact-resistant shingles (hail-rated) land at $150–$220/sq installed and often qualify for insurance discounts in high-hail zones like Colorado and Texas.

Underlayment—the barrier between decking and shingles—costs $8–$15 per square for synthetic felt (which I prefer over traditional 15-lb felt because it doesn't rot). Drip edge, flashing, and hardware (nails, primer) run another $5–$10 per square. That's $13–$25 per square in supporting materials.

Metal roofing (standing seam or metal shakes) costs $300–$600 per square installed, making it a $6,000–$12,000 material bill on a 20-square roof before labor. It's expensive upfront but lasts 40–50 years versus asphalt's 15–20, and insurance companies often knock 20–30% off premiums for metal roofs in storm-prone areas.

Wood shake roofing—architecturally stunning but a maintenance nightmare—runs $400–$800 per square and requires annual treatment to prevent rot. I only recommend it if you're committed to the upkeep.

• 3-tab asphalt shingles: $90–$120 per square installed
• Architectural asphalt shingles: $130–$180 per square installed
• Impact-resistant shingles (hail-rated): $150–$220 per square installed
• Metal standing seam: $300–$600 per square installed
• Wood shake: $400–$800 per square installed
• Underlayment & flashing: $13–$25 per square

Permits, Inspections & Hidden Compliance Costs

Most counties require a roofing permit—non-negotiable—and the cost ranges wildly. Suburban Northeast towns charge $500–$800 and schedule inspection 2 weeks out. Rural Midwest counties charge $200–$400 and inspect within days. Urban jurisdictions and high-value areas (parts of California, Colorado, New Jersey) charge $1,000–$1,500. That fee funds the inspection process and ensures the work meets current building codes.

If your municipality requires reroofing to meet current energy codes (many do for roof replacements), expect $200–$500 in additional material costs for code-compliant underlayment or ventilation upgrades. Some jurisdictions now require ridge venting or soffit venting upgrades—$300–$600 in material and labor.

Hail or storm damage claims sometimes require engineer certification before permits issue. That's a separate $400–$800 fee. Old wood roof decking (1970s and earlier homes) sometimes needs reinforcement or partial replacement, which the inspector flags and you pay for: $2–$5 per sq ft of decking.

Skipping permits creates legal liability. Your homeowner's insurance explicitly excludes unpermitted roof work, meaning if wind damage occurs post-replacement, they deny the claim. Selling your house triggers title issues because unpermitted work shows up in inspection disclosures in most states, and buyers demand $2,000–$5,000 credit to remediate.

Regional Cost Variation: Northeast vs. South vs. Midwest

A 20-square asphalt shingle roof replacement costs $12,000–$15,000 in the Northeast (New York, Massachusetts, Connecticut, Pennsylvania), $8,500–$11,000 in the Midwest (Ohio, Michigan, Indiana, Wisconsin), and $8,000–$10,500 in the South (Texas, Georgia, Florida, North Carolina).

Northeast premiums stem from union labor scales (many roofing shops are union-affiliated in New York and Massachusetts), higher materials markup by distributors, and shorter working season compressed into 8 months. Winter roof work in January costs 15–20% more because of cold-weather material handling and worker scheduling constraints. Coastal areas (Massachusetts, New Jersey, Connecticut) add 10–15% for hurricane-resistant fastening requirements and modified flashing specs.

Midwest pricing reflects lower labor rates ($45–$55/sq vs. $55–$65/sq in the Northeast) but also material availability—some small-town distributors stock limited shingle colors, forcing special orders with 3-week lead times and $200–$500 upcharges. Winter work is brutal here too; Minnesota, Wisconsin, and Michigan roofing typically shuts down November through March, so spring projects experience 4–8 week booking delays and rush premiums.

Southern roofing is cheapest because labor rates are lower and the year-round season eliminates seasonal bottlenecks. Florida adds 5–10% for wind-resistant installation standards and impact-resistant shingle requirements in some counties (Miami-Dade, Broward). Texas and Georgia work year-round at consistent rates. Louisiana and Mississippi sometimes require engineering certification for storm-prone areas, adding $600–$1,200.

Red Flag: Contractor Scams & How to Avoid Them

The roofing industry attracts more fraud per capita than any trade I've worked alongside. Here's what I've seen repeatedly:

**The Insurance Claim Scam**: Contractor offers to "handle the insurance claim" and covers your deductible. What actually happens: they file an inflated claim ($25,000 when damage is $12,000), pocket the difference, and when the insurance inspector revisits, it flags fraud on your policy. You're liable, not them. Only file claims yourself and get competitive bids before letting a contractor near your insurance paperwork.

**The Low-Ball Bid With Change Orders**: Contractor quotes $9,000 for a 20-square roof. When work starts, they "discover" rotted decking, faulty flashing, or need venting upgrades—each adding $1,500–$3,000. You're contractually obligated to pay because you signed the change order. Protect yourself by requiring a detailed pre-bid inspection and a fixed-price contract with a "maximum $500 allowance for unforeseen structural issues."

**The 3-Tab vs. Architectural Switch**: Contractor quotes 3-tab shingles ($100/sq wholesale cost) but installs architectural shingles ($140/sq wholesale) without your approval. They pocket the $800–$1,200 difference and the homeowner ends up with better shingles but no negotiating power. Always specify shingle brand and model in the contract.

**The Permit Dodge**: Contractor tells you permits cost $800 and "waste time," offers to skip them and save you $1,000. They pocket the permit fee and leave you without warranty coverage or insurance protection. Never agree to unpermitted work.

**The Missing Underlayment**: Tear-off is done on day one, but inspecting the decking at close of day (when the contractor's gone) reveals no underlayment installed yet. Next morning, contractor says "we'll add it tomorrow," but the roofing is already half-done. You catch it, they charge $1,500 to retrofit it, or you end up with an under-protected roof. Require underlayment installation the same day as tear-off completion.

**The Warranty Lie**: Contractor verbally guarantees "lifetime workmanship warranty" but the signed contract says "5 years, transferable only if you stay in the house." The paper contract wins in court. Get warranties in writing, specified by years and coverage terms.

How to Get Accurate Quotes & Negotiate Price

Request three bids minimum, and each one should include: square footage calculation (they measure it, not estimate), tear-off and haul costs, specific shingle brand and model, warranty terms (workmanship and material), permit costs itemized separately, and timeline with weather contingencies.

When comparing bids, ignore price alone. A $9,500 bid and a $12,000 bid might both be fair if the $12,000 includes structural repairs or premium underlayment. A $7,500 bid is a red flag—that's below cost for quality labor and materials, and the contractor will cut corners (skip drip edge, use cheap nails, thin out underlayment) or hit you with change orders.

Negotiate on materials and timeline, not labor. Asking a crew to "work cheaper" gets you slower work or a second-tier crew. Asking if you buy shingles direct from a distributor and they install—sometimes saves $300–$600 because they avoid material markup. Negotiate timeline flexibility instead: "Can we shift this to May when your schedule is lighter?" Often nets you a 5–8% discount because contractors prefer steady booking over rush premiums.

Referral networks matter. A contractor who's done work for your neighbor builds trust and often prices more competitively for recurring work in the area. But don't let relationship cloud judgment—still require a written contract and permit.
