Your Roof Is 20 Years Old. How Much Will Replacement Actually Cost?

Get instant ballpark estimates for roof replacement and repair based on real pricing data from thousands of completed projects nationwide

Your roof is showing its age. Maybe you’re seeing granules in the gutters. Maybe a few shingles blew off last storm. Maybe you’re just hitting that 20-year mark and wondering how much longer you’ve got. The first question is always: what’s this going to cost?

Roof replacement is one of the biggest home improvement investments, typically running $8,000 to $25,000 for an average home. But that range is so wide it’s almost useless. Your actual cost depends on roof size, material choice, complexity, and where you live. This calculator narrows it down.

Use this tool to get realistic budget expectations for your specific roof, compare different material options and their long-term value, understand what drives roofing costs up or down, and prepare for contractor conversations with accurate knowledge.

Signs You Need a New Roof vs. Repairs

Not every roof problem means replacement. Here’s how to tell whether you need repairs, replacement, or just maintenance.

Replace Your Roof When

Age exceeds material lifespan. Asphalt shingles last 20-30 years. If yours are 25+ years old, replacement is smarter than repairs regardless of current condition. You’re on borrowed time.

Widespread granule loss. Check your gutters after rain. Heavy granule accumulation means shingles are failing across the roof, not just in spots. Once granules are gone, shingles deteriorate rapidly.

Multiple leaks or leak history. One leak is a repair. Three leaks in different areas suggest systemic failure. Continuing to patch an old roof throws money away.

Sagging roof deck. Visible sagging indicates structural problems from prolonged water damage or inadequate framing. This requires more than new shingles. The deck needs repair or replacement.

Daylight visible through roof boards. If you see light in your attic coming through the roof, water is coming through too. Widespread gaps mean replacement.

Curling, buckling, or missing shingles across large areas. Isolated damage is repairable. Damage across multiple slopes or more than 30% of the roof means replacement is more economical.

Repair Is Sufficient When

Damage is localized. A few missing shingles in one area, a single leak, or storm damage to one section can be repaired if the rest of the roof is sound.

Roof is under 15 years old. Younger roofs with isolated problems are worth repairing. You’ll get years more service from the undamaged sections.

Flashing failures only. Flashing around chimneys, vents, and valleys fails before shingles. Flashing repair or replacement without touching shingles is common and cost-effective.

Minor leak with clear source. A single leak from an identifiable source (cracked boot, lifted flashing, impact damage) is a repair, not a replacement trigger.

The 30% Rule

General guidance: if repairs would affect more than 30% of your roof, or if repair costs exceed 30% of replacement cost, replacement usually makes more financial sense. You’ll get a complete warranty, consistent appearance, and reset the aging clock.

Roofing Materials: Complete Cost Comparison

Your material choice is the single biggest cost variable. Here's what each option costs, how long it lasts, and who it's best for.

Asphalt Shingles: The Standard Choice

Asphalt shingles cover 80% of American homes. They're affordable, available everywhere, and every roofer knows how to install them.

3-Tab Shingles: $3.50-$5.50 per square foot installed. The budget option. Flat appearance, 15-20 year lifespan, basic warranty. Cost for 2,000 sq ft roof: $7,000-$11,000.

Architectural Shingles: $4.50-$7.00 per square foot installed. The most popular choice. Dimensional appearance, 25-30 year lifespan, better warranties. Cost for 2,000 sq ft roof: $9,000-$14,000.

Premium/Designer Shingles: $6.00-$10.00 per square foot installed. Luxury asphalt mimicking slate or cedar. 30-50 year lifespan, enhanced warranties, highest curb appeal in the asphalt category. Cost for 2,000 sq ft roof: $12,000-$20,000.

Best for: Budget-conscious homeowners, typical resale timelines (5-15 years), homes in moderate climates, anyone wanting proven performance and easy repairs.

Pros: Lowest upfront cost, wide color selection, easy to repair, every contractor can install.

Cons: Shorter lifespan than premium materials, vulnerable to extreme heat, requires replacement every 20-30 years.

Metal Roofing: The Long-Term Value Play

Metal roofing has grown from 5% to 15% market share in the last decade. Higher upfront cost, but 50+ year lifespan changes the math.

Exposed Fastener Metal: $5.00-$8.00 per square foot installed. Screws visible on surface. Common on agricultural and some residential applications. 30-40 year lifespan. Cost for 2,000 sq ft roof: $10,000-$16,000.

Standing Seam Metal: $9.00-$16.00 per square foot installed. Concealed fasteners, clean lines, premium appearance. 50+ year lifespan. Cost for 2,000 sq ft roof: $18,000-$32,000.

Metal Shingles/Tiles: $10.00-$18.00 per square foot installed. Metal formed to look like shingles, slate, or tile. Combines metal durability with traditional aesthetics. 50+ year lifespan. Cost for 2,000 sq ft roof: $20,000-$36,000.

Best for: Forever homes, areas with heavy snow (metal sheds snow), high-wind or wildfire zones, energy-conscious homeowners (metal reflects heat), anyone wanting 50+ year solution.

Pros: Longest lifespan, fire resistant, energy efficient, environmentally friendly (recyclable), low maintenance, handles extreme weather.

Cons: Higher upfront cost, can be noisy in rain (mitigated with proper underlayment), denting possible from large hail, specialized installation.

Tile Roofing: The Premium Traditional Option

Clay and concrete tile are common in Spanish, Mediterranean, and Southwestern architecture. Beautiful and durable, but heavy and expensive.

Concrete Tile: $10.00-$18.00 per square foot installed. Less expensive than clay, many style options, 40-50 year lifespan. Cost for 2,000 sq ft roof: $20,000-$36,000.

Clay Tile: $15.00-$30.00 per square foot installed. Classic terra cotta or glazed options, 75-100 year lifespan. Cost for 2,000 sq ft roof: $30,000-$60,000.

Best for: Mediterranean, Spanish, or Southwestern style homes, hot climates (tile breathes and insulates well), homeowners wanting 50-100 year roof, areas where tile is architecturally appropriate.

Pros: Extremely long lifespan, fire resistant, excellent in hot climates, distinctive appearance, low maintenance.

Cons: Very heavy (may require structural reinforcement), expensive, fragile (walking on tile breaks it), specialized installers required, limited to certain architectural styles.

Slate Roofing: The Century-Long Investment

Natural slate is the premium roofing material. Properly installed, slate roofs last 100+ years. Many slate roofs from the 1800s are still functioning today.

Natural Slate: $20.00-$45.00 per square foot installed. Varies dramatically by slate quality and source. Welsh and Vermont slate command premium prices. 100+ year lifespan. Cost for 2,000 sq ft roof: $40,000-$90,000.

Synthetic Slate: $12.00-$25.00 per square foot installed. Rubber or polymer composite mimicking slate appearance. 50+ year lifespan, much lighter weight. Cost for 2,000 sq ft roof: $24,000-$50,000.

Best for: Historic homes, luxury properties, multi-generational homes where 100-year lifespan has value, architectural styles demanding authentic slate.

Pros: Century-long lifespan, unmatched aesthetics, fire resistant, increases home value significantly, ultimate curb appeal.

Cons: Extremely expensive, very heavy (structural assessment required), specialized installers scarce in many areas, fragile to foot traffic, repairs can be difficult and expensive.

Wood Shake: The Natural Aesthetic

Cedar shakes and shingles offer a distinctive natural look. Popular in coastal, rustic, and upscale residential applications.

Cedar Shingles: $8.00-$14.00 per square foot installed. Machine-cut, uniform appearance. 25-30 year lifespan. Cost for 2,000 sq ft roof: $16,000-$28,000.

Cedar Shakes: $10.00-$18.00 per square foot installed. Hand-split, rustic texture. 30-40 year lifespan. Cost for 2,000 sq ft roof: $20,000-$36,000.

Best for: Craftsman, Cape Cod, and rustic architectural styles, homeowners prioritizing natural aesthetics, areas without wildfire restrictions.

Pros: Beautiful natural appearance, good insulation, ages attractively to silver-gray.

Cons: Fire risk (banned in some areas), requires regular maintenance, vulnerable to rot and insects without treatment, shorter lifespan than metal or tile.

Flat Roof Materials: Commercial and Modern Residential

Flat and low-slope roofs require different materials than pitched roofs. Common on commercial buildings, modern homes, and as underlying roofs for rooftop decks.

TPO (Thermoplastic Polyolefin): $6.00-$10.00 per square foot installed. White reflective membrane, energy efficient, 20-30 year lifespan. Most popular commercial choice. Cost for 2,000 sq ft: $12,000-$20,000.

EPDM (Rubber): $5.00-$9.00 per square foot installed. Black rubber membrane, proven durability, 20-30 year lifespan. Cost for 2,000 sq ft: $10,000-$18,000.

Modified Bitumen: $6.00-$12.00 per square foot installed. Asphalt-based rolled roofing, torch or peel-and-stick application, 15-20 year lifespan. Cost for 2,000 sq ft: $12,000-$24,000.

PVC Membrane: $7.00-$14.00 per square foot installed. Chemical resistant, ideal for restaurants and buildings with rooftop equipment exhaust, 20-30 year lifespan. Cost for 2,000 sq ft: $14,000-$28,000.

Best for: Commercial buildings, modern architectural homes, any structure with low slope (under 2:12 pitch).

What Drives Roofing Costs Up or Down

Beyond material choice, several factors significantly impact your final cost.

Roof Size and Measurement

Roofing is priced by the 'square,' meaning 100 square feet. A 2,000 square foot roof is 20 squares. Your roof's square footage is larger than your home's footprint due to pitch and overhangs.

Simple rule: multiply your home's footprint by 1.15 to 1.5 depending on roof pitch. A 1,500 sq ft single-story home typically has a 1,700-2,200 sq ft roof.

Every additional square adds material and labor cost. Accurate measurement is essential for accurate estimates.

Roof Pitch (Steepness)

Steeper roofs cost more. Pitch is measured in rise over run. A 6:12 pitch rises 6 inches for every 12 inches of horizontal run.

Low pitch (2:12 to 4:12): Standard pricing. Roofers work efficiently, safety equipment minimal.

Moderate pitch (5:12 to 8:12): 10-20% cost increase. Safety equipment required, slower work pace.

Steep pitch (9:12 to 12:12): 25-50% cost increase. Specialized safety equipment, much slower installation, higher risk.

Extreme pitch (over 12:12): 50-100% cost increase. Very few contractors work at these pitches. Expect difficulty finding qualified installers.

Roof Complexity

Simple roofs with few penetrations and straightforward geometry cost less than complex roofs with dormers, valleys, skylights, and multiple levels.

Simple (basic gable or hip): Base pricing. Two or four slopes meeting at simple angles.

Moderate complexity: 10-20% increase. Multiple valleys, a few dormers, standard penetrations (vents, chimney).

High complexity: 25-50% increase. Many dormers, multiple roof levels, numerous skylights, intricate architectural details.

Cost drivers: Valleys require careful flashing and add leak risk. Dormers multiply the linear feet of edge work. Skylights need precise flashing. Every penetration is a potential leak point requiring careful waterproofing.

Tear-Off and Deck Condition

What's under your current shingles matters significantly.

Single layer tear-off: Standard pricing. Most common scenario for first replacement.

Double layer tear-off: Add $0.50-$1.50 per square foot ($1,000-$3,000 for typical roof). More labor, more disposal, more time.

Overlay (no tear-off): Saves $1,000-$3,000 but not recommended. Adds weight, hides deck damage, voids many warranties, and creates problems for next replacement. Most quality contractors won't do it.

Deck repair: If plywood or OSB decking is damaged, replacement runs $70-$150 per sheet plus labor. Minor soft spots are common. Extensive damage significantly increases project cost.

Accessibility and Height

Can a truck get close? How high is the roof? These practical factors affect labor cost.

Single story, good access: Base pricing. Easy material staging, minimal equipment.

Two story: 10-15% increase. More ladder work, conveyor or crane for materials.

Three+ story: 20-35% increase. Significant equipment requirements, safety concerns, slower progress.

Difficult access (landscaping, narrow lots, no truck access): 10-25% increase. Manual material handling adds labor hours.

Geographic Location

Labor rates vary significantly by region.

High-cost markets: San Francisco, NYC, Boston, Seattle, LA. Expect 30-50% above national average.

Average markets: Most suburban areas, mid-size cities. Calculator estimates most accurate.

Lower-cost markets: Rural areas, smaller cities, lower cost-of-living regions. 15-25% below national average.

Climate factors: Areas with extreme weather (hurricanes, heavy snow, frequent hail) may have higher prices due to demand and building code requirements.

The Roof Replacement Process: What to Expect

Understanding the process helps you prepare and evaluate contractor professionalism.

Before Work Begins

Inspection and measurement: Contractor assesses current roof condition, takes measurements, notes any issues requiring attention.

Detailed proposal: You receive written proposal with scope, materials, timeline, cost, payment schedule, and warranty terms.

Permits: Contractor pulls necessary permits. Most jurisdictions require permits for re-roofing. This triggers inspections that verify code compliance.

Material ordering: Materials ordered 1-2 weeks before start. Specialty materials may have longer lead times.

Your prep: Move vehicles from driveway and areas where debris might fall. Protect or move items in attic (vibration can knock things loose). Note fragile landscaping near the house.

Day 1: Tear-Off and Deck Inspection

Crew arrives early (typically 7-8 AM) with equipment and dumpster. They lay tarps around your home's perimeter to catch debris.

Old roofing comes off. This is loud. Debris slides down tarps into truck or dumpster. Expect significant noise from 7 AM until late afternoon.

Deck inspection happens as tear-off progresses. Damaged decking is marked for replacement. You may be consulted if extensive damage is found.

If tear-off finishes same day, underlayment goes down before crew leaves. This provides temporary weather protection.

Day 2+: Installation

Ice and water shield (if required) goes at eaves, valleys, and around penetrations. Synthetic underlayment covers entire deck.

Drip edge and starter strip installed at perimeter. These prevent water infiltration at roof edges.

Shingle installation begins at bottom, working up. Each course overlaps the one below. Proper nail placement is critical for warranty and performance.

Valleys, flashings, and penetrations addressed as installation progresses. These details separate quality installation from hack work.

Ridge cap and vents complete the job. Ridge vents provide essential attic ventilation.

Completion and Cleanup

Final inspection by contractor verifies all work complete and up to standard.

Magnetic sweeping of yard and driveway picks up stray nails. This should be thorough. Missed nails mean flat tires.

Debris removal: All old materials, packaging, and waste should leave with the crew. Your property should be cleaner than when they started.

City/county inspection: If permits were pulled (they should have been), a final inspection verifies code compliance. This protects you.

Warranty registration: Manufacturer warranties require proper registration. Contractor should handle this or provide documentation for you to complete.

Timeline Expectations

Simple roof, asphalt shingles, small crew: 1-2 days.

Average home, standard complexity: 2-3 days.

Large or complex roof: 3-5 days.

Tile, slate, or specialty materials: 5-10+ days.

Weather delays: Rain stops work. Crews will tarp exposed areas and return when weather clears. Spring and fall offer best conditions in most regions.

Best Time to Replace Your Roof

Timing affects price, contractor availability, and installation quality.

Fall (September-November): Best Overall

Ideal weather: Cool enough for comfortable work, warm enough for proper shingle sealing. Most manufacturers recommend installation above 40-45 degrees Fahrenheit for proper adhesive activation.

Before winter: New roof ready before snow, ice, and winter storms. Peace of mind for the cold months.

Moderate demand: Less frantic than summer storm season. Better contractor availability than peak season.

Spring (March-May): Second Best

Good weather conditions: Similar to fall. Rain can be more common depending on region.

Preparing for storm season: New roof ready before summer storms, hurricanes (Atlantic/Gulf), and hail season (Midwest).

Rising demand: Contractors booking up. Schedule early for spring installation.

Summer (June-August): Peak Season

Longest days: More working hours. Projects complete faster when weather cooperates.

Heat challenges: Extreme heat is hard on workers and can affect installation quality. Shingles become overly pliable and can be damaged during installation.

Highest demand: Post-storm repair backlog, plus planned replacements. Prices may be 10-20% higher. Longer wait times.

Winter (December-February): Possible but Challenging

Temperature limitations: Below 40 degrees Fahrenheit, shingle adhesive strips don't seal properly. Some manufacturers void warranties for cold-weather installation.

Best winter pricing: Lowest demand means best prices and fastest scheduling. If your climate allows (mild winters), consider it.

Snow delays: Any accumulation stops work. Projects may stretch across multiple weeks due to weather windows.

When winter makes sense: Emergency situations, extremely mild climates, or if significant discount makes weather risk worthwhile.

Understanding Roofing Warranties

Roofing warranties are complex. Understanding them prevents unpleasant surprises when you need coverage.

Manufacturer Material Warranty

What it covers: Defects in the shingles or roofing material itself. If shingles fail prematurely due to manufacturing defects, the manufacturer covers replacement materials.

What it doesn't cover: Labor costs (usually), damage from improper installation, storm damage, normal wear.

Duration: 25-50 years typically, but often prorated after initial 10-15 years. A '30-year' warranty may only cover 100% of material cost for the first 10 years, then decline.

Important: Warranty requires proper installation per manufacturer specs. Using non-approved accessories, improper ventilation, or installation errors can void warranty.

Workmanship Warranty (Contractor)

What it covers: Installation errors. If the roof leaks due to improper flashing, incorrect nailing, or other installation failures, contractor repairs at no cost.

Duration: Varies widely. 1-2 years is minimal. 5-10 years is good. Some premier contractors offer lifetime workmanship warranties.

Critical factor: Warranty is only as good as the contractor's longevity. A 10-year warranty from a company that closes in 3 years is worthless. Choose established contractors.

Enhanced/Extended Warranties

Many manufacturers offer enhanced warranties when their products are installed by certified contractors using their complete roofing system (shingles, underlayment, starter, ridge cap, all same brand).

GAF Golden Pledge: 50-year material, 25-year workmanship when installed by Master Elite contractor with GAF accessories. One of the strongest warranties available.

Owens Corning Platinum Protection: 50-year material, lifetime workmanship when installed by Platinum Preferred contractor.

CertainTeed 5-Star: 50-year material, 25-year workmanship with SELECT ShingleMaster installers.

Worth it? Enhanced warranties cost $200-$600 more but provide significantly better coverage. Recommended for anyone planning to stay in their home long-term.

Warranty Killers: What Voids Coverage

Improper ventilation: Most warranties require specific attic ventilation ratios. Inadequate ventilation voids coverage.

Layover installation: Installing over old shingles often voids or limits warranty.

Wrong accessories: Using different brand underlayment, ice shield, or accessories can void manufacturer warranty.

Unlicensed installation: Some warranties require licensed contractor installation.

Failure to register: Many warranties require registration within 30-60 days of installation.

Insurance and Roof Replacement

Your roof's age and condition affect your insurance in ways many homeowners don't realize.

How Roof Age Affects Insurance

Roofs under 10 years: Full replacement cost coverage standard. Insurance typically pays full replacement regardless of depreciation.

Roofs 10-20 years: May shift to actual cash value (ACV) coverage. Insurance pays depreciated value, not full replacement cost. A 15-year-old roof might only get 50-60% of replacement cost.

Roofs over 20 years: Many insurers require inspection, may refuse to renew, or offer only ACV coverage. Premium increases common.

Impact-resistant shingles: Many insurers offer 5-35% premium discount for Class 4 impact-resistant shingles. In hail-prone areas, this discount can be significant.

New Roof Insurance Benefits

Premium reduction: New roof often reduces homeowners insurance premium 5-20%. Call your insurer for specific quote.

Coverage restoration: If your old roof was on ACV, new roof restores full replacement cost coverage.

Policy eligibility: Some insurers won't cover homes with roofs over certain age. New roof opens more insurance options, potentially better rates.

Wind and hail coverage: Better terms available for newer roofs, especially with impact-resistant materials.

Filing Claims vs. Paying Out of Pocket

Not every roof problem justifies an insurance claim. Filing claims affects your rates and insurability.

File claim when: Damage exceeds your deductible significantly, damage results from covered peril (storm, hail, fire), and cost would be financial hardship without coverage.

Pay out of pocket when: Damage barely exceeds deductible (a $3,500 repair with $2,500 deductible means insurance only pays $1,000), damage results from maintenance failure (not covered anyway), or you've filed claims recently (multiple claims in 3-5 years can cause non-renewal).

Important: Filing a claim that gets denied still counts against you with some insurers. Only file when coverage is clear and amount is significant.

Hiring the Right Roofing Contractor

Roofing is one of the most complained-about contractor categories. Vetting properly protects your investment.

Essential Qualifications

State licensing: Every state licenses roofing contractors. Verify through your state licensing board. Unlicensed work is illegal and leaves you unprotected.

Insurance: Require certificates of insurance for general liability ($1M minimum) and workers' compensation. Call the insurance company to verify active coverage. Contractors without workers' comp expose you to liability if workers are injured.

Local presence: Established local address, local references, local reputation. Storm chasers and traveling crews have no accountability once they leave town.

Manufacturer certifications: GAF Master Elite, Owens Corning Platinum Preferred, CertainTeed SELECT ShingleMaster. These certifications require training, standards, and enable enhanced warranties.

Getting and Comparing Bids

Get at least three written bids. More for large projects. All bids should be detailed and comparable.

Bids should include: Material brand and specific product line, scope of work (tear-off, deck inspection, ice shield, underlayment, etc.), ventilation plan, flashing replacement, timeline, payment schedule, warranty terms, who handles permits.

Compare apples to apples: Different shingle lines from the same brand perform differently. Verify all bids specify equivalent materials.

Beware extreme outliers: Bid 30% below others means corners will be cut. Bid 40% above others may indicate price gouging or unnecessary work. Dig into why.

Red Flags to Avoid

Storm chasers: Appear after storms, door-to-door solicitation, out-of-state plates, no local address. These contractors do the work and disappear. Warranty claims are impossible.

Deductible waivers: Any contractor offering to cover or waive your insurance deductible is committing insurance fraud. Walk away.

High-pressure tactics: Demanding immediate decisions, 'today only' pricing, creating urgency. Good contractors understand you need time.

Large upfront payment: Deposits over 30% are unusual. Requests for 50% or more upfront suggest cash flow problems or scam risk.

No written contract: Everything should be documented. Verbal agreements provide no protection.

Won't pull permits: Avoiding permits means avoiding inspection. Work may not meet code, voiding warranties and creating liability.

Payment Structure Best Practices

Standard payment schedule: 10-30% deposit, balance upon completion. Some contractors request material delivery payment (30-50%) when materials arrive, final payment at completion.

Never pay in full upfront. Retain at least 10% until final walkthrough confirms satisfactory completion and inspection is passed.

Credit card payments: Provide dispute rights if work is unsatisfactory. Worth the 3% contractor fee for protection on large projects.

Lien waivers: On final payment, obtain lien waiver from contractor confirming all materials and subcontractors are paid. Protects you from liens if contractor doesn't pay suppliers.

Next Steps: From Estimate to Installation

If You're Just Starting to Research

Use the calculator above to understand ballpark costs for your situation. Determine whether repair or replacement makes sense. Consider material options and their long-term value. Check your insurance policy for roof age implications.

If You're Ready for Quotes

Know your roof's approximate size and complexity. Decide on material preferences or remain open to contractor recommendations. Plan to get at least 3 detailed written bids. Verify licensing and insurance before signing anything. Understand warranty options.

Frequently Asked Questions About Roofing Costs

How much does a new roof cost?

A new roof costs $8,000 to $25,000 for most homes, with an average around $12,000 to $15,000 for architectural asphalt shingles on a 2,000 square foot roof. Cost varies by material: asphalt shingles run $4.50-$7 per square foot, metal roofing $9-$16, tile $10-$30, and slate $20-$45 per square foot installed. Roof size, complexity, pitch, and your location also significantly affect price.

How long does a roof last?

Roof lifespan depends on material. 3-tab asphalt shingles last 15-20 years. Architectural shingles last 25-30 years. Metal roofing lasts 50+ years. Clay tile lasts 75-100 years. Slate lasts 100+ years. Climate, ventilation, maintenance, and installation quality all affect actual lifespan. Most asphalt roofs in average conditions last 20-25 years before needing replacement.

Should I repair or replace my roof?

Repair your roof if damage is localized, the roof is under 15 years old, and repair costs are under 30% of replacement cost. Replace your roof if it's past its expected lifespan, has widespread granule loss or damage, has multiple leaks, shows sagging or structural issues, or if repair costs exceed 30% of replacement. The 30% rule: if repairs affect more than 30% of roof area, replacement usually makes more financial sense.

What is the best roofing material?

The best roofing material depends on your priorities. Architectural asphalt shingles offer the best value for most homeowners, with 25-30 year lifespan at $4.50-$7 per square foot. Metal roofing is best for longevity and energy efficiency at $9-$16 per square foot with 50+ year lifespan. Clay tile is best for hot climates and Mediterranean aesthetics. Slate is best for historic homes and maximum lifespan but costs $20-$45 per square foot.

How long does roof replacement take?

Roof replacement takes 1-3 days for most homes with asphalt shingles. Simple roofs on single-story homes may complete in one day. Average complexity roofs take 2-3 days. Large or complex roofs take 3-5 days. Tile, slate, and specialty materials take 5-10+ days. Weather delays extend timelines. Plan for noise and disruption during working hours, typically 7 AM to 6 PM.

Does a new roof increase home value?

A new roof increases home value and recoups 60-70% of its cost at resale according to national remodeling studies. More importantly, a new roof makes homes easier to sell. Buyers and their inspectors scrutinize roofs. A home with a 20-year-old roof may require price reductions or struggle to sell. A new roof also improves insurance terms and may reduce premiums by 5-20%.

What is the best time of year to replace a roof?

Fall (September-November) is the best time to replace a roof in most regions. Weather is ideal for installation, demand is moderate, and your new roof is ready before winter. Spring is second best. Summer works but brings heat challenges and peak pricing. Winter is possible in mild climates but cold temperatures affect shingle sealing. Avoid scheduling during your region's storm season when contractor demand spikes.

How do I know if a roofing contractor is legitimate?

Verify legitimacy by checking state contractor licensing through your state licensing board, confirming insurance (call their insurer to verify active coverage), looking for established local presence (physical address, local references), checking manufacturer certifications (GAF Master Elite, Owens Corning Platinum), and reading reviews for patterns. Avoid contractors who appear after storms, offer to waive deductibles, demand large upfront payments, or won't provide written contracts.

Does homeowners insurance cover roof replacement?

Homeowners insurance covers roof replacement when damage results from covered perils: storms, hail, wind, fallen trees, fire. Insurance does NOT cover replacement due to age, wear, or maintenance neglect. Coverage may be replacement cost (full replacement paid) or actual cash value (depreciated amount). Roofs over 10-15 years old often shift to actual cash value coverage. Your deductible applies, and many policies have separate, higher wind/hail deductibles.

What does a roofing warranty cover?

Roofing warranties include two types. Manufacturer warranty covers material defects, typically 25-50 years, often prorated after 10-15 years, and usually excludes labor costs. Workmanship warranty from your contractor covers installation errors, typically 1-10 years depending on contractor. Enhanced warranties from manufacturer-certified contractors combine both, covering materials and labor for 25-50 years. Warranties require proper installation, adequate ventilation, and timely registration.
