Quick Answer
Florida roofs last 20-30% SHORTER than national averages due to extreme climate conditions.
Roof Lifespan by Material (Florida vs National)
| Material | National Average | Florida Reality | Lifespan Reduction |
|---|---|---|---|
| Asphalt shingles (3-tab) | 20-25 years | 15-18 years | 25-30% shorter |
| Architectural shingles | 25-30 years | 18-22 years | 25-30% shorter |
| Metal roofing | 40-50 years | 40-50 years | No reduction ✅ |
| Concrete tile | 50+ years | 40-50 years | Underlayment fails faster |
| Clay tile | 100+ years | 50-75 years | Tile lasts, underlayment fails |
| Flat roof (TPO/EPDM) | 15-20 years | 12-15 years | 20-25% shorter |
Why Florida Roofs Fail Faster:
- UV radiation: 40% more intense than northern states (breaks down asphalt shingles)
- Extreme heat: 150-170°F roof surface temps in summer (accelerates deterioration)
- High humidity: 70-80% average (promotes algae, mold, wood rot)
- Hurricane exposure: 130-150 mph wind requirements (roofs take severe abuse)
- Salt air corrosion: Coastal areas (fastener rust, metal flashing failure)
- Daily thermal cycling: 80°F temp swings day to night (expansion/contraction stress)
Bottom line: If manufacturer says 25-year warranty, expect 18-22 years in Florida. Plan accordingly.

How Long Does Each Roofing Material Last in Florida?
1. Asphalt Shingles (3-Tab) - 15-18 Years in Florida
National average: 20-25 years Florida reality: 15-18 years Reduction: 25-30% shorter lifespan
Why 3-Tab Shingles Fail Faster in Florida
What are 3-tab shingles?
- Most basic asphalt shingle type
- Single layer, flat appearance
- Three tabs per shingle (hence the name)
- Thinnest option (lightest weight, lowest cost)
Florida-specific failure patterns:
Years 1-5: Normal performance
- Shingles seal properly
- Good waterproofing
- Minimal granule loss
Years 6-10: Early deterioration begins
- Granules start washing off (UV damage)
- Edges begin to curl (thermal cycling)
- Algae streaks appear (humidity + heat)
- Minor lifting during storms (60-80 mph winds)
Years 11-15: Accelerated failure
- Significant granule loss (50%+ missing)
- Widespread curling/cupping
- Multiple shingles blow off during thunderstorms
- Leaks begin (valleys, penetrations fail first)
- Brittle, crack easily when stepped on
Years 15-18: End of life
- Bare asphalt exposed (no UV protection)
- Severe curling across entire roof
- Missing shingles after every storm
- Multiple leaks, interior damage
- Replacement required

- ❌ HOA restrictions (some require shingle/tile look)
5. Concrete Tile - 40-50 Years in Florida
National average: 50+ years Florida reality: 40-50 years (tile lasts 50+, but underlayment fails at 15-20 years) Reduction: Minimal for tile itself, but underlayment needs replacement
Understanding Tile Roof Lifespan in Florida
IMPORTANT: Concrete tile itself lasts 50-75 years in Florida, but the underlayment (waterproof barrier underneath) fails at 15-20 years.
What is a tile roof system?
- Roof deck (plywood/OSB)
- Underlayment (felt or synthetic, waterproof layer)
- Battens (wood strips tiles hook onto)
- Tiles (concrete or clay, top layer)
The Florida tile roof paradox:
✅ Tiles last forever: Concrete tiles withstand FL climate (heat, UV, humidity) for 50-75 years ❌ Underlayment fails: Trapped heat under tiles (140-160°F) cooks underlayment, causing failure at 15-20 years
Underlayment replacement cost:
- Remove tiles, replace underlayment, reinstall tiles: $8,000-15,000 (2,000 sq ft)
- Tiles reused (if undamaged)
- Required every 15-20 years in Florida
Performance timeline:
Years 1-15: Excellent
- Tiles look great
- Perfect waterproofing
- Withstands hurricanes
- Energy efficient (thermal mass keeps home cool)
Years 15-20: Underlayment failing
- Leaks begin (underlayment deteriorated)
- Tiles still perfect condition
- Underlayment replacement needed: $8,000-15,000
- Tiles removed, new underlayment installed, tiles replaced
Years 20-40: Second underlayment cycle
- New underlayment installed at year 15-20
- Tiles continue to perform
- Another underlayment replacement at year 35-40: $8,000-15,000
Years 40-50: Tiles still functional
- Original tiles (40-50 years old) still waterproof
- May have some cracks (5-10% of tiles)
- Underlayment on 3rd replacement cycle
- Decision point: Continue replacing underlayment OR full tear-off and new roofing system
Types of concrete tile in Florida:
Flat Concrete Tile:
- Mediterranean/Spanish look
- Popular in South Tampa, Davis Islands
- Good wind resistance (heavy weight)
- Lifespan: 50+ years (tiles), 15-20 years (underlayment)
- Cost: $18,000-30,000 (2,000 sq ft)
S-Tile (Barrel Tile):
- Classic Spanish mission style
- Curved barrel shape
- Very heavy (needs strong roof structure)
- Lifespan: 50+ years
- Cost: $20,000-35,000
Low-Profile Tile:
- Flatter appearance
- Better for lower-pitch roofs
- Easier to walk on (maintenance)
- Lifespan: 50+ years
- Cost: $17,000-28,000
Florida-specific tile advantages:
✅ Hurricane resistance:
- Weight prevents blow-off (150-180 lb per square)
- Interlocking design
- Rated to 150+ mph winds
✅ Fire resistance:
- Class A fire rating (non-combustible)
- Important for wildfire-prone areas (east Hillsborough County)
✅ Energy efficiency:
- Thermal mass (stays cooler than shingles)
- Air gap under tiles (ventilation)
- $200-400/year AC savings
✅ Aesthetic appeal:
- Mediterranean/Spanish style (fits Florida architecture)
- High-end appearance
- Increases home value
Florida-specific tile disadvantages:
❌ Underlayment replacement:
- Required every 15-20 years: $8,000-15,000
- Disrupts home (tiles removed/replaced)
- Not a simple repair
❌ Weight:
- Requires strong roof structure (not all homes suitable)
- Structural engineer assessment needed ($400-800)
- May require reinforcement ($5,000-15,000)
❌ Fragile when walked on:
- Tiles crack under foot traffic
- Difficult to access roof for repairs (satellite dish, solar panels)
- Professional must walk on tiles (not DIY)
Cost comparison over 50 years:
Concrete tile:
- Initial install: $25,000
- Underlayment replacement year 18: $12,000
- Underlayment replacement year 36: $12,000
- Total 50-year cost: $49,000
Asphalt shingles:
- 3 replacements over 50 years: $15,000 × 3 = $45,000
Metal roofing:
- Install once: $28,000
Verdict: Tile is MOST EXPENSIVE over 50 years (underlayment replacement cycle), but has aesthetic/resale advantages in certain Tampa Bay neighborhoods.
When to choose concrete tile:
- ✅ Mediterranean/Spanish-style home (architectural fit)
- ✅ HOA requirements (South Tampa, Davis Islands, Palma Ceia)
- ✅ Resale value priority (tile = premium in certain markets)
- ✅ Hurricane zone (maximum wind resistance)
- ❌ Budget-conscious (most expensive long-term)
- ❌ Roof structure questionable (weight concerns)
6. Clay Tile - 50-75 Years in Florida
National average: 100+ years Florida reality: 50-75 years (tile lasts 100+, underlayment fails at 15-20 years) Reduction: Same underlayment issue as concrete tile
Clay tile vs concrete tile:
Clay tile advantages:
- Longer lifespan: 75-100 years (vs 50-75 concrete)
- More durable in Florida heat/UV
- Better color retention (natural clay vs painted concrete)
- Premium aesthetic (smoother, more refined look)
Clay tile disadvantages:
- 30-50% more expensive than concrete tile
- Even heavier weight (requires stronger structure)
- More fragile (cracks more easily when walked on)
Costs:
- Installation: $28,000-45,000 (2,000 sq ft) - premium price
- Underlayment replacement (every 15-20 years): $10,000-18,000
- Total 50-year cost: $55,000-70,000 (most expensive option)
When to choose clay tile:
- ✅ Historic homes (preservation requirements)
- ✅ Ultra-premium properties ($1M+ homes)
- ✅ Want absolute longest lifespan material
- ✅ South Tampa historic districts (Hyde Park, Palma Ceia)
7. Flat Roofs (TPO/EPDM/Modified Bitumen) - 12-15 Years in Florida
National average: 15-20 years Florida reality: 12-15 years Reduction: 20-25% shorter
Why flat roofs fail faster in Florida:
❌ UV exposure:
- Flat membrane = full sun exposure (no shade)
- UV breaks down rubber/plastic materials
- 40% more UV in Florida = faster degradation
❌ Standing water (ponding):
- Florida rain: 55+ inches/year
- Water ponds on low spots
- Accelerates membrane failure
❌ Heat buildup:
- Black EPDM = 160-180°F surface temps
- Cooks membrane from above and below (hot attic underneath)
- Thermal cycling stress
Flat roof materials for Florida:
TPO (Thermoplastic Polyolefin) - BEST for Florida:
- White reflective surface (cool roof)
- Heat-welded seams (no adhesive to fail)
- Lifespan: 15-20 years in Florida
- Cost: $8,000-15,000 (1,500 sq ft flat roof)
- Most popular for commercial/low-slope residential
EPDM (Rubber membrane):
- Black surface (absorbs heat)
- Glued/taped seams
- Lifespan: 12-15 years in Florida
- Cost: $7,000-12,000
- Good for: Budget-conscious
Modified Bitumen:
- Torch-down or self-adhering
- Multi-layer system
- Lifespan: 12-15 years
- Cost: $7,500-13,000
- Good for: Small flat sections
When flat roofs are common in Tampa Bay:
- Commercial buildings (retail, office, industrial)
- Mid-century modern homes (1950s-1970s architecture)
- Porch/garage roofs on 2-story homes
- Additions/sunrooms
5 Factors That Affect Roof Lifespan in Florida
Factor 1: Installation Quality (Accounts for 30-40% of Lifespan)
Perfect installation in Florida climate:
✅ Proper ventilation:
- Soffit intake vents + ridge exhaust vents
- Attic temp should be <130°F (Florida requirement)
- Poor ventilation = roof cooks from underneath, fails 30% faster
✅ Hurricane-rated installation:
- 6-nail pattern (minimum, vs 4-nail standard)
- Sealed edges (high-wind adhesive)
- Starter strip properly installed
- Ridge caps with extra adhesive
✅ Drip edge and proper flashing:
- Drip edge at eaves AND rakes (prevents water infiltration)
- Step flashing at walls/chimneys
- Valley flashing (ice/water shield underlayment in valleys)
✅ Quality underlayment:
- Synthetic underlayment (vs cheap felt)
- High-temp rated (for Florida heat)
- Properly lapped/sealed
Poor installation reduces lifespan:
- Missing ventilation: -30% lifespan (18-year shingles last 12 years)
- 4-nail pattern (not 6-nail): High-wind failure, shingles blow off
- Cheap underlayment: Fails at 10-12 years, leaks begin
- No drip edge: Water gets under shingles, rots decking
How to verify quality installation: ✅ Verify contractor has FL contractor license (check DBPR.gov) ✅ Require permits (inspections catch poor work) ✅ Ask for photos during installation (underlayment, ventilation, flashing) ✅ Check attic after install (proper ventilation visible)
Factor 2: Roof Color (Lighter = Longer Lifespan)
Roof color affects surface temperature and lifespan:
| Shingle Color | Surface Temp (Summer) | Lifespan Impact |
|---|---|---|
| White/Light gray | 130-140°F | +10-15% lifespan (baseline) |
| Tan/Beige | 140-150°F | +5-10% lifespan |
| Medium gray/brown | 150-160°F | 0% (standard lifespan) |
| Dark gray | 160-170°F | -5-10% lifespan |
| Black/Dark brown | 170-180°F | -10-15% lifespan |
Why color matters in Florida:
- Lighter colors reflect 40-60% of heat
- Dark colors absorb 70-80% of heat
- Higher temps = faster asphalt deterioration
- 20-30°F temp difference = 2-3 year lifespan difference
Energy savings too:
- Light roof: $400-600/year AC savings (2,000 sq ft home)
- Dark roof: Baseline (no savings)
Most popular shingle colors in Tampa Bay:
- Weathered Wood (light tan/gray) - best lifespan + energy
- Oyster Gray (light gray) - good lifespan + modern look
- Driftwood (medium tan) - classic Florida look
- Charcoal (medium gray) - popular but hotter
When to choose dark vs light: ✅ Choose light colors (white, tan, light gray):
- Energy savings priority
- Want maximum lifespan
- South-facing roof (most sun exposure)
❌ Avoid dark colors (black, dark brown):
- Reduces lifespan 2-3 years
- Adds $400-600/year to AC costs
- Only choose if aesthetic requirement (modern look)
Factor 3: Roof Pitch (Steeper = Longer Lifespan)
Roof pitch affects water drainage and lifespan:
| Roof Pitch | Slope | Water Drainage | Lifespan Impact |
|---|---|---|---|
| Flat/Low (0-3/12) | Nearly flat | Poor (water ponds) | -20-30% lifespan |
| Low pitch (4-6/12) | Gentle slope | Moderate drainage | Standard lifespan |
| Medium pitch (7-9/12) | Steeper slope | Good drainage | +5-10% lifespan |
| Steep pitch (10/12+) | Very steep | Excellent drainage | +10-15% lifespan |
Why pitch matters in Florida:
- Florida gets 55+ inches rain/year (4th wettest state)
- Afternoon thunderstorms: 1-3 inches in 30-60 minutes
- Flat roofs = water sits on roof = accelerated wear
- Steep roofs = water runs off quickly = less exposure
Tampa Bay roof pitch norms:
- Most homes: 4/12 - 6/12 (standard pitch)
- Ranch homes: 3/12 - 5/12 (lower pitch)
- 2-story homes: 6/12 - 8/12 (steeper pitch)
- Historic homes: 8/12 - 12/12 (traditional steep pitch)
Can’t change your pitch, but can optimize: ✅ Ensure proper drainage (gutters clear, downspouts functional) ✅ Use high-quality underlayment (ice/water shield in valleys) ✅ Inspect low-slope sections more frequently
Factor 4: Proximity to Coast (Salt Air Corrosion)
Distance from saltwater affects roof lifespan:
| Distance from Coast | Lifespan Impact | Special Requirements |
|---|---|---|
| Beachfront (0-500 ft) | -15-20% lifespan | Stainless steel fasteners REQUIRED |
| Coastal (0.5-2 miles) | -10-15% lifespan | Stainless steel recommended |
| Near coast (2-5 miles) | -5-10% lifespan | Corrosion-resistant flashing |
| Inland (5+ miles) | Standard lifespan | Standard materials OK |
Salt air corrosion effects:
❌ Galvanized steel fasteners:
- Rust through in 8-12 years (coastal areas)
- 15-18 years inland
- Rusted fasteners = shingles blow off
❌ Aluminum/steel flashing:
- Corrodes in 10-15 years (coastal)
- Valley flashing failure = leaks
❌ Metal roof fasteners:
- Exposed fasteners rust (5V crimp metal)
- Must use stainless steel or catastrophic failure
Coastal areas in Tampa Bay:
-
Extreme corrosion zone (0-1 mile):
- Clearwater Beach, St. Pete Beach, Treasure Island
- Apollo Beach, Ruskin waterfront
- Safety Harbor, Dunedin waterfront
-
Moderate corrosion zone (1-5 miles):
- Most of Clearwater, St. Petersburg
- Coastal South Tampa (Bayshore, Davis Islands)
- Palmetto, Bradenton near water
Coastal roofing upgrades (REQUIRED): ✅ Stainless steel fasteners: +$600-1,200 (316 marine-grade) ✅ Corrosion-resistant flashing: Copper or heavy aluminum ✅ Synthetic underlayment: Won’t degrade in humidity/salt
ROI of coastal upgrades:
- Upgrade cost: $1,000-2,000
- Prevents premature failure: Extends life 5-8 years
- Value: $1,000-2,000 cost vs $15,000 premature replacement = 700% ROI
Factor 5: Maintenance (Regular Inspections Extend Life 3-5 Years)
Proper maintenance extends Florida roof lifespan 15-25%:
✅ Annual professional inspection: $200-400/year
- Check for damaged/missing shingles
- Clear debris from valleys
- Inspect flashing (chimneys, vents, valleys)
- Check attic ventilation
- Document condition (for insurance)
✅ Gutter cleaning (2x/year minimum):
- Spring (before rainy season)
- Fall (after leaf drop)
- Clogged gutters = water backs up under shingles = leaks
✅ Tree trimming (keep branches 6+ feet away):
- Overhanging branches drop debris
- Shade = moisture retention = algae/moss
- Hurricane risk (branches become projectiles)
✅ Algae cleaning (when black streaks appear):
- Professional soft wash: $350-600
- Prevents wood rot (algae retains moisture)
- Extends life 2-4 years
✅ Minor repairs immediately:
- Replace 1-2 missing shingles: $150-300
- Prevents small problem becoming big leak
- Delaying repairs = $1,000s in damage
Maintenance timeline for Florida roofs:
Asphalt shingles:
- Years 1-8: Inspect annually, minimal maintenance
- Years 9-15: Inspect annually, algae cleaning as needed, minor repairs
- Years 15-18: Inspect 2x/year, expect frequent repairs
- Year 18+: Replace
Metal roofing:
- Years 1-20: Inspect every 2-3 years, minimal maintenance
- Years 20-40: Inspect annually, check fasteners, consider repainting at year 30
- Years 40-50: Inspect annually, plan for re-coat or replacement
Tile roofing:
- Years 1-15: Inspect annually, replace broken tiles as needed
- Year 15-20: Underlayment replacement ($10,000-15,000)
- Years 20-35: Inspect annually
- Year 35-40: Second underlayment replacement
Cost vs benefit:
- Annual maintenance: $400-800/year
- Lifespan extension: 3-5 years
- Value: 3-5 years of roof life = $15,000-25,000 avoided replacement
- ROI: $400/year × 18 years = $7,200 spent, $20,000+ value = 280% ROI
How to Maximize Your Roof Lifespan in Florida
Strategy 1: Choose the Right Material for Your Situation
Long-term ownership (15+ years):
- ✅ Metal roofing (40-50 years, best ROI over time)
- ✅ Impact-resistant architectural shingles (20-25 years + insurance discount)
Medium-term ownership (8-15 years):
- ✅ Architectural shingles (18-22 years, best balance)
Short-term ownership (<8 years) or rental:
- ✅ 3-tab shingles (15-18 years, lowest cost)
Coastal properties:
- ✅ Metal roofing (salt air immune)
- ✅ Architectural shingles + stainless steel fasteners
HOA restrictions (Mediterranean style):
- ✅ Concrete/clay tile (aesthetic requirement)
- ✅ Metal tile (looks like clay, easier maintenance)
Strategy 2: Hire Quality Installer (Worth 5-7 Years Extra Life)
Verify contractor credentials:
✅ Florida contractor license:
- CCC (Certified Roofing Contractor) or CBC (Certified Building Contractor)
- Check license at myfloridalicense.com/dbpr
- Verify no violations/complaints
✅ Insurance:
- General liability ($1M minimum)
- Workers compensation (protects you from liability)
- Ask for certificates of insurance
✅ Local reputation:
- 5+ years in business (avoid storm chasers)
- Verifiable reviews (Google, BBB, Angi)
- Local address/showroom (not P.O. box)
✅ Permits:
- All Florida roof replacements require permits
- Contractor should handle permitting ($300-700)
- Inspections verify quality work
Red flags (poor installers): ❌ No FL license (illegal, insurance won’t cover) ❌ Cash-only, no contract ❌ Large upfront payment (FL law limits to 10%) ❌ “Skip permits to save money” (illegal, voids insurance) ❌ Pressure tactics (“today only” pricing)
Strategy 3: Proper Attic Ventilation (Adds 5+ Years)
Why ventilation matters in Florida:
- Attic temps reach 140-160°F without ventilation
- Hot attic cooks roof from underneath
- Reduces shingle lifespan 30-40%
Proper ventilation requirements:
✅ Intake vents (soffit vents):
- 1 sq ft per 150 sq ft attic space
- Fresh air enters at eaves
✅ Exhaust vents (ridge vents):
- Run length of roof peak
- Hot air escapes at ridge
- Creates airflow (intake → exhaust)
Cost vs benefit:
- Add ventilation: $800-2,000
- Lifespan increase: 5-7 years
- Energy savings: $200-400/year (cooler attic = less AC load)
- ROI: Pays for itself in 3-5 years
Strategy 4: Choose Light-Color Shingles
Roof color impact on lifespan:
- Light colors (white, tan, light gray): +2-3 years lifespan
- Dark colors (black, dark brown): -2-3 years lifespan
Energy savings:
- Light roof: $400-600/year AC savings
- Dark roof: Baseline (no savings)
Best colors for Tampa Bay:
- Weathered Wood (tan/gray blend)
- Oyster Gray (light gray)
- Driftwood (light tan)
Strategy 5: Annual Maintenance Plan
Create a roof maintenance schedule:
Every spring (April-May):
- ✅ Professional inspection ($200-400)
- ✅ Gutter cleaning
- ✅ Tree trimming (before hurricane season)
- ✅ Address any minor repairs
Every fall (October-November):
- ✅ Gutter cleaning
- ✅ Post-hurricane season inspection
- ✅ Check attic for leaks
As needed:
- ✅ Algae cleaning (when black streaks appear)
- ✅ Replace damaged/missing shingles immediately
Cost: $400-800/year Benefit: 3-5 years extra lifespan = $15,000-25,000 value
When to Replace vs Repair: Lifespan Decision Point
Use remaining lifespan to decide:
Replace if:
- ✅ Roof age is 80%+ of expected lifespan
- Asphalt shingles: 14+ years old (80% of 18-year lifespan)
- Metal: 35+ years old (80% of 45-year lifespan)
- ✅ Damage >25% of roof surface
- ✅ Multiple leaks across roof
- ✅ Failed professional inspection
- ✅ Planning to sell within 2 years (new roof adds value)
Cost: $12,000-28,000 depending on material
Repair if:
- ✅ Roof age <60% of expected lifespan
- Asphalt shingles: <11 years old
- Metal: <25 years old
- ✅ Isolated damage (<10% of roof)
- ✅ Single leak, not widespread
- ✅ Minor storm damage
Cost: $200-2,000 depending on extent
Frequently Asked Questions
How long does a 30-year shingle roof really last in Florida?
Manufacturer claims: 30-year warranty Florida reality: 18-22 years
Why the discrepancy?
- Warranty is prorated (depreciated value after 10 years)
- Based on ideal climate conditions (not Florida’s extreme heat/UV)
- Manufacturer warranty ≠ actual lifespan
What “30-year shingle” means:
- 30 years in moderate climate (northern states)
- 18-22 years in Florida
- Warranty covers defects, not normal wear from climate
Do metal roofs last longer in Florida?
Yes - metal is the ONLY material that maintains full lifespan in Florida.
- National lifespan: 40-50 years
- Florida lifespan: 40-50 years (no reduction)
Why metal performs better: ✅ UV-resistant (painted finish lasts 30-40 years) ✅ Heat-reflective (60-70% reflection vs asphalt absorption) ✅ Hurricane-proof (150-180 mph wind rating) ✅ Salt air resistant (Galvalume coating) ✅ No organic material (algae/moss can’t grow)
How often should I replace my roof in Florida?
By material:
- Asphalt shingles: Every 15-22 years
- Metal roofing: Every 40-50 years (once in lifetime)
- Tile roofing: Underlayment every 15-20 years, tiles last 50-75 years
- Flat roof (TPO): Every 12-18 years
Most Tampa Bay homeowners: Replace roof 2-3 times during 40-50 years of ownership (if using asphalt shingles).
Does roof color affect lifespan in Florida?
Yes - significantly.
- Light colors (white, light gray, tan): +10-15% lifespan
- Dark colors (black, dark brown): -10-15% lifespan
Example:
- Light shingle lifespan: 20-22 years
- Dark shingle lifespan: 16-18 years
- Difference: 4 years
Plus energy savings: Light roof saves $400-600/year on AC.
Should I get a roof inspection before buying a home in Florida?
ABSOLUTELY YES.
Why it’s critical in Florida:
- Roofs fail faster in FL (15-18 years vs 25 years national)
- Sellers may not disclose age/condition
- Insurance won’t cover roofs 15+ years old
- Buyers often negotiate $10,000-20,000 credit for old roofs
What inspection reveals:
- Actual roof age (vs claimed age)
- Condition (remaining lifespan)
- Hidden damage (leaks, structural issues)
- Proper installation (permits, ventilation)
Cost: $200-400 (best $400 you’ll spend)
Negotiation leverage:
- Roof 15+ years: Demand replacement OR $10-15K credit
- Roof 12-15 years: Negotiate $3-8K credit
- Roof <10 years: Minimal/no concession
How do I know when my roof needs to be replaced?
Key indicators replacement is imminent:
- Age: 15+ years old (asphalt shingles)
- Granule loss: Significant accumulation in gutters
- Curling shingles: Edges lifting across roof
- Multiple leaks: Not just one isolated spot
- Missing shingles: After every storm
- Failed inspection: Home inspector recommends replacement
- Insurance denial: Company won’t insure old roof
