Roof replacement typically costs between $5,000 and $25,000 for a single-family home, depending on the roof size, materials chosen, and your location.
The price varies widely because roofing is sold by the square — a roofing square equals 100 square feet — and most homes need 15 to 30 squares. A small ranch house might need 15 squares; a large two-story home might need 30 or more. Material costs per square range from roughly $150 for basic asphalt shingles to $500 or more for premium materials like architectural shingles, metal, or slate. Labor costs per square typically run $100 to $200, though this shifts by region and contractor.
Before getting quotes, measure or find your roof size. Your property tax record, home inspection report, or real estate listing often lists square footage of the roof itself. Multiply that by 1.3 to account for pitch and waste. Divide by 100 to get the number of squares you need.
Key Takeaways
- Roof replacement cost depends on three things: the number of squares (100-square-foot sections) your roof covers, the material you choose, and labor rates in your area.
- Asphalt shingles are the cheapest material at $150 to $250 per square installed; metal, wood, and tile cost significantly more but last longer.
- Getting three written quotes from licensed contractors is standard practice and helps you compare price, warranty terms, and timeline.
- Removing the old roof adds $500 to $2,000 depending on how many layers exist; some contractors include this, others charge separately.
How Material Choice Affects Total Cost
The material you select is usually the largest variable in the final bill. Asphalt shingles, the most common choice, cost $150 to $250 per square installed and last 15 to 25 years. Architectural (or dimensional) asphalt shingles cost $200 to $350 per square and look more textured; they last 20 to 30 years. Both are sold in bundles that cover roughly one-third of a square.
Metal roofing (typically aluminum or steel) costs $300 to $600 per square installed and lasts 40 to 70 years. It reflects heat, which can lower cooling costs in hot climates. Wood shakes cost $400 to $800 per square and require regular maintenance. Slate and tile cost $600 to $1,200 per square and last 50 to 100 years but are heavy and require structural reinforcement.
The material choice also affects labor time. Metal and tile take longer to install than asphalt, so labor costs rise. Some contractors charge a flat rate per square regardless of material; others charge separately for materials and labor, which makes comparison easier.
What Contractors Include and Exclude
A roofing quote should specify what is and is not included. Most contractors include the cost of new shingles or panels, nails, underlayment, and labor to install them. Many also include removal of the old roof and disposal of debris.
Costs that often appear as add-ons are flashing replacement (metal strips that seal seams and valleys), new gutters, structural repairs if the decking underneath is rotted, and permits. Flashing replacement typically costs $500 to $2,000. If the contractor finds rotted decking during removal, that repair is usually billed separately at $50 to $150 per square foot of decking replaced. Permits vary by municipality but often run $100 to $500.
Ask each contractor whether their quote includes removal and disposal, flashing, permits, and cleanup. If one quote is much lower than others, check what it excludes — you may end up paying those costs anyway.
Labor Costs and Regional Variation
Labor is typically $100 to $200 per square, but this shifts by region and contractor experience. Urban areas and regions with high cost of living generally pay more. A contractor in rural Montana may charge $100 per square; the same contractor in the San Francisco Bay Area might charge $250.
Complexity also raises labor cost. A straightforward gable roof takes less time than a roof with multiple valleys, dormers, or steep pitch. Steep roofs require more safety equipment and time, so contractors charge more. A roof with a 4:12 pitch (4 inches of rise per 12 inches of run) is standard; a 10:12 pitch is steep and will cost more.
Contractor experience and licensing matter. A licensed, insured contractor with good reviews will cost more than an unlicensed handyman, but the licensed contractor carries liability insurance, guarantees their work, and is easier to pursue if something goes wrong.
Getting and Comparing Quotes
Contact three to five licensed roofing contractors in your area and ask for written quotes. Each quote should list the number of squares, the material and brand, the cost per square, labor cost, removal and disposal cost, flashing, permits, and the total. It should also state the warranty on materials and workmanship, the timeline, and when payment is due.
Do not choose based on price alone. A quote that is significantly lower than the others may indicate the contractor is cutting corners, using lower-grade materials, or planning to skip steps like proper underlayment or flashing. Ask for references from recent jobs and call them. Ask whether the contractor is licensed and insured, and verify both with your state or local licensing board.
Most contractors require a deposit (typically 25 to 50 percent) when you sign the contract, with the balance due upon completion. Some require payment in full before starting. Avoid contractors who demand full payment upfront.
When Insurance or information Covers Roof Replacement
Homeowners insurance may cover roof replacement if the damage is from a covered event — typically wind, hail, or fire — rather than wear and tear. If a storm damages your roof, contact your insurance company and ask for a claims adjuster to inspect it. The adjuster will determine whether the damage is covered and what amount the insurer will pay toward replacement.
If you receive an insurance payout, it usually goes toward the cost but may not cover the full amount, especially if your policy has a deductible or if the roof is old. Some policies pay actual cash value (which accounts for depreciation) rather than replacement cost. Read your policy or call your agent to understand what your roof coverage includes.
Low-income homeowners in some states may find information through community development programs or nonprofit organizations that help with critical home repairs. These programs are rare and often have long waiting lists. Contact your local housing authority or 211 (a referral service) to ask whether programs exist in your area.
Timeline and Seasonal Factors
A typical roof replacement takes three to seven days, depending on roof size and complexity. Weather delays this — contractors cannot work in heavy rain or snow. Spring and fall are peak roofing seasons, so contractors may have longer wait times and may charge more. Winter and summer have shorter wait times but weather is less predictable.
If you need the roof done quickly, expect to pay more or accept a longer wait. If you can be flexible on timing, scheduling the work in late fall or early spring often means lower prices and faster completion. Ask the contractor for an estimated start date and completion date before you sign the contract.
Frequently Asked Questions
Can I replace just part of my roof instead of the whole thing?
Partial replacement is possible if damage is limited to one section, but it is usually not recommended. The new shingles will not match the old ones in color or texture, and the old roof may fail soon after. Most contractors suggest full replacement if more than 30 percent of the roof is damaged or if the roof is more than 15 years old.
What is the difference between a roof inspection and a full replacement quote?
An inspection tells you the condition of your roof and whether replacement is needed soon. A quote is a detailed estimate for the cost of replacement. Many contractors offer free inspections to generate quotes. If you want an independent assessment before getting quotes, hire a home inspector or engineer to inspect the roof for a fee (typically $200 to $500).
Do I need a permit to replace my roof?
Most municipalities require a permit for roof replacement. The contractor usually handles this and includes the permit cost in the quote. Permits may support the work meets building code and that the contractor is licensed. Skipping a permit can cause problems when you sell the home or file an insurance claim.
What warranty should I expect?
Material warranties typically last 15 to 50 years depending on the shingle type and manufacturer. Workmanship warranties (guarantees on the installation) usually last 5 to 10 years. Ask the contractor what they may provide and get the warranty terms in writing. Some contractors offer extended warranties for an additional cost.
How do I know if my roof needs replacement or just repair?
Signs of needed replacement include missing or curling shingles, leaks in multiple areas, sagging, or an age over 20 years. A single leak or a few missing shingles can often be repaired. A licensed roofer can inspect your roof and tell you whether repair or replacement makes sense.
