The single most common question we get at California First Roofing is: what does a new roof cost in San Diego? The honest answer is that it depends on five variables — material, square footage, decking condition, access, and warranty tier. Below is a transparent 2026 breakdown of what San Diego homeowners are actually paying, based on hundreds of projects we've completed across La Jolla, Rancho Santa Fe, Del Mar, Carlsbad, Poway, and every other neighborhood in San Diego County.
Average cost by material (installed, 2026)
- Architectural asphalt shingle: $9–$14 per sq ft — the workhorse of San Diego residential roofing. A typical 2,400 sq ft home runs $22,000–$34,000.
- Concrete tile (Boral, Eagle, MCA): $15–$25 per sq ft — the signature roof of Spanish Colonial and Mediterranean homes. $36,000–$60,000 for a typical home.
- Authentic clay tile: $20–$40 per sq ft — hand-formed Mission-style tile. $48,000–$96,000 for estate homes.
- Standing-seam metal (24-gauge Kynar): $18–$30 per sq ft — 50+ year lifespan, Class-A fire rated.
- Natural slate: $30–$60 per sq ft — heirloom-quality, 75+ year lifespan.
- TPO / PVC single-ply (commercial flat): $8–$14 per sq ft installed.
- Lift & relay tile: 50–65% of full replacement — reuse existing tile with new underlayment.
What drives the number up (or down)
Decking condition is the biggest variable. If your existing plywood or 1x6 skip sheathing is dry-rotted, cracked, or spaced beyond current code, we replace it — typically $2–$4 per sq ft. On older Mission Hills and North Park homes we often replace 15–30% of the decking; on newer homes it's under 5%.
Access and pitch matter more than most homeowners realize. Steep pitches (over 7:12) and multi-story homes require additional safety scaffolding, longer install times, and higher labor rates. A single-story ranch in Clairemont costs materially less per square foot than a three-story hillside home in La Jolla.
Warranty tier is the last variable. A standard 10-year workmanship warranty from a lesser contractor is a different product than a 50-year GAF Golden Pledge or Owens Corning Preferred warranty from a factory-certified installer.
Hidden costs to watch for
Cheap bids in San Diego almost always omit: proper synthetic underlayment (only felt paper), stainless flashing at valleys and walls (only galvanized), ice-and-water shield at eaves, ridge and eave venting to code, or dumpster and cleanup fees. Get every line item in writing.

Frequently Asked Questions
How much does it cost to replace a roof in San Diego in 2026?
Most San Diego homes fall between $22,000 and $60,000 installed. Architectural shingle runs $9–$14 per sq ft, concrete tile $15–$25, standing-seam metal $18–$30, and clay tile or slate higher. Decking condition, pitch, access, and warranty tier are the biggest variables.
Is a tile roof worth the extra cost over shingle in San Diego?
For most Spanish, Mediterranean, and Colonial homes — yes. Tile lasts 50+ years, handles San Diego heat and UV better than asphalt, and preserves resale value. Shingle is the smarter economic choice on shallow-pitch modern or ranch-style homes.
Does San Diego roof replacement cost include permit and Title 24?
Our estimates include the City or County of San Diego re-roof permit, Title 24 cool-roof compliance where applicable, disposal, and final inspection. Anything hidden until decking is exposed — like rotted plywood — is called out as a documented unit price up front.
How long does a full roof replacement take?
A typical single-family San Diego home takes 2–5 working days: tear-off day one, decking and underlayment day two, install days three to four, cleanup and inspection day five. Tile and slate homes run longer; shingle re-covers are quicker.
Do you offer financing for roof replacement?
Yes. We partner with HFS, GreenSky, and Service Finance to offer 0% intro-APR and long-term fixed-rate financing on approved credit, including PACE alternatives. Terms and approval are handled at estimate — no obligation.
