Cost to Replace a Roof in Southern California (2026 Pricing Guide)

The honest answer to “what does a new roof cost” in Southern California is: it depends on your specific home. Material, pitch, county, HOA requirements, and what we find under the existing layers all move the number. The more useful answer is the monthly number — most SoCal homeowners finance through GoodLeap with $0 down, which puts a typical replacement in the $200–$400/month rangeon approved credit (FICO 580+, 7-25 year terms). Below is the county-by-county, material-by-material breakdown of the all-in ranges, plus the line items most contractors won’t put in writing.

The short version

For a typical 2,000 sq ft (single-story, average pitch) SoCal home — these are ranges, not quotes. A real number requires a real inspection:

• Asphalt shingle reroof (GAF Master Elite) — $15,000 – $28,000+ all-in
• Concrete tile reroof (Eagle California Collection) — $22,000 – $50,000+ all-in
• TPO / flat-roof reroof (commercial or residential flat) — $18,000 – $40,000+ all-in
• Clay tile (specialty, low volume) — $40,000 – $65,000+ depending on the tile source

The wide ranges are real — anyone giving you a single number sight-unseen is either a salesperson with commission bait or a contractor who’s about to surprise you on the change-order at install day. There are real variables, and they’re the next four sections.

The variables that actually move the price

1. Roof size (squares, not square feet)

Roofers price in “squares” — 1 square = 100 sq ft of roof surface (not floor surface). A 2,000 sq ft single-story home with a moderate pitch usually has 22–28 squares of actual roof area. A 2,500 sq ft two-story with a steeper pitch can have 18–22 squares (less roof per sq ft of house). We measure with EagleView aerial reports + on-site verification on every estimate.

2. Pitch (the steepness)

A steep roof (8/12 or steeper) costs more to install because it requires toe-boards, safety setup, and slower work. Pitch matters most on tile, where steeper pitches need fewer hip-and-ridge tiles per linear foot — but more labor.

3. Material

See full table below. The biggest cost driver. Asphalt shingle is the baseline; concrete tile is roughly 2x; clay tile is 3-4x.

4. What we find under the old roof

This is the single biggest source of “why did the bill go up” complaints in this industry. Once we tear off the old roof, we sometimes find rotted decking, failed flashings, or water damage to the underlying sheathing. We price out rotted decking replacement at a published per-sheet rate (typically $110–$170 per 4×8 sheet of OSB, depending on the sheet thickness + access). We never inflate it after the fact — the rate is on the original estimate, so you know what each sheet costs before we open up the roof.

5. Title 24 compliance

Title 24 cool-roof code is mandatory on most California reroofs. Compliant products (GAF Reflector Series, Eagle California Collection) add roughly 5-12% to material cost vs. non-RS equivalents but save the homeowner $200-$600/year in AC bills depending on house and climate zone. Non-compliant roofs need offsetting energy upgrades elsewhere (insulation, HVAC) — usually more expensive than just buying compliant shingles.

Asphalt shingle reroof — full breakdown

The most common SoCal residential reroof. Here’s a 2,000 sq ft / 25 squares typical home, with TMC’s GAF Master Elite installation and Reflector Series shingles:

• Tear-off + dump fees: $1,500 – $3,000
• Synthetic underlayment (better than felt): $900 – $1,500
• Drip edge + starter + ice/water shield: $800 – $1,400
• GAF Timberline HDZ® RS or Grand Sequoia® RS shingles: $6,500 – $11,500
• Ridge cap (GAF Seal-A-Ridge): $500 – $1,000
• Ventilation upgrade if needed: $400 – $1,200
• Labor (Master Elite installation): $4,500 – $9,500
• Permit + Title 24 documentation: $400 – $1,000
• Cleanup + magnetic nail sweep: included
• GAF Golden Pledge warranty registration: included

Total range: $15,000 – $28,000+ for a typical 2,000 sq ft single-story Inland Empire home with average access. Add 8-15% for 2-story or steep-pitch. Coastal Orange County, Newport Beach, and Pasadena historic-district homes regularly run higher due to access, HOA requirements, and permit fees.

Concrete tile reroof — full breakdown

For a 2,000 sq ft / 25 squares home with Eagle California Collection tile (Capistrano profile is the most common across SoCal):

• Tear-off of existing tile + haul-away: $2,800 – $5,500
• Premium underlayment (modified bitumen or synthetic): $1,500 – $2,800
• Battens + counter-battens if needed: $1,000 – $2,000
• Eagle California Collection tile: $7,500 – $16,000
• Hip and ridge tiles: $1,200 – $2,500
• Flashing kit (lead jacks, valley metal, eave riser): $900 – $1,800
• Labor: $6,500 – $15,000
• Permit + Title 24 documentation: $500 – $1,500
• Eagle Authorized Installer warranty registration: included

Total range: $22,000 – $50,000+. Lightweight tile (when the original framing was specced for shingle) runs roughly 10-15% higher in product cost but eliminates the need for structural reinforcement. Premium profiles (Tapered Slate, Golden Eagle, custom-color blends) push the upper end higher.

TPO / flat-roof reroof — full breakdown

For a 2,000 sq ft single-story flat or low-slope (commercial, residential addition, or HOA building):

• Tear-off of existing membrane or built-up: $1,500 – $3,500
• ISO or EPS insulation board: $3,000 – $5,500
• Cover board (HD ISO or fiberboard): $1,500 – $3,000
• TPO membrane (60-mil reinforced, GAF EverGuard®): $4,500 – $8,500
• Mechanical fasteners + plates: $900 – $1,800
• Edge metal + termination bar + flashings: $1,200 – $2,500
• Labor (welded seams, penetration boots): $5,000 – $13,000
• Permit + documentation: $500 – $1,500

Total range: $18,000 – $40,000+. Add roof drains, scuppers, or PV reattach as separate line items. 80-mil premium membrane runs higher.

County-by-county price drift

Same roof, different county — labor and permit costs vary across the 5-county SoCal market:

• Riverside County — Baseline. Permit fees $250–$650 most cities. Lowest labor cost in our service area.
• San Bernardino County — Similar to Riverside; permit fees vary widely (Big Bear is its own paperwork ecosystem).
• Orange County — Add roughly 5-10% to total. Permit fees $400–$900. HOA review can add 1-3 weeks.
• Los Angeles County — Add roughly 8-15%. Permit fees higher; LA County Green Building Code adds extra documentation; some cities require certified payroll on certain jobs.
• San Diego County — Add roughly 5-12%. Permit fees mid-range; coastal zones have additional setback / aesthetic-review rules.

How to evaluate roofing quotes

Cheap quotes hide cost in the line items they leave out. When you compare contractors, look for these specific things:

1. Synthetic underlayment named explicitly. If the quote says “15 lb felt” or doesn’t name the underlayment at all, you’re getting felt — short life, weak in wind.
2. The exact shingle SKU and CRRC ID. If they say “GAF Timberline” without specifying HDZ RS or non-RS, they’re likely planning to install the non-RS line (cheaper, but fails Title 24 in most SoCal climate zones).
3. Decking replacement per-sheet rate. If they don’t publish a per-sheet rate, they’ll surprise you at install day.
4. Manufacturer warranty tier. “Lifetime” is marketing speak — the actual GAF tiers are System Plus (40-year), Silver Pledge (50-year material), and Golden Pledge (25-yr workmanship + 50-yr material). Golden Pledge is the only one that covers TMC’s workmanship for 25 years — and it’s only available through Master Elite contractors.
5. CF1R + CF2R Title 24 documentation explicitly named. The contractor signs these — they have to be on the quote.
6. CSLB license number. A real C39 number lets you check status, complaints, and bond on CSLB’s site. TMC’s is C39 #1103611.

Financing — what most people actually do

Roughly 60% of TMC’s residential replacement customers finance some or all of the project. Two common paths:

• $0 down / 0% intro APR through GoodLeap— TMC’s primary lender partner. Pre-qualifies in 2 minutes, soft credit pull, terms 5-25 years. See full financing details →
• Insurance claims — If hail / wind / storm damage is at play and your carrier approves a claim, your out-of-pocket is usually just the deductible. TMC provides the written inspection report you can share with your carrier; we don't file or manage claims on a homeowner's behalf.

Next step

Every TMC estimate is written, itemized, and free. We measure the roof with EagleView + on-site verification, photograph any concerns, flag rotted-decking risk before tear-off, and stamp every quote with Title 24 documentation. No high-pressure callback, no “today-only” pricing, no salesperson’s commission layered on top.
