Searchers want a San Diego reroof number. The honest deliverable is a bid checklist. Installed totals change with measured squares, material, deck, access, and which city or County counter issues the permit.
Top Pro Roofing SD is a referral service. We do not install, we do not hold a C-39, and we do not publish 2026 invoice examples. Call (760) 750-5557. We introduce a licensed independent roofer. You contract with that pro.
Material-specific method pages: tile roof replacement cost, tile roof cost per square foot, how much roofing costs, slate, metal vs shingle. Repair versus replace: repair vs replacement. Lifespan context: how long a roof lasts here.
What you are actually buying
A full replacement is not “shingles.” It is tear-off or a documented lift-and-relay, deck inspection, underlayment, flashing, the field material, hip and ridge, haul-away, permit, inspection, and two different warranties (manufacturer enrollment versus workmanship).
A layover over old shingles can look cheaper on the first page of a bid. It hides deck damage, adds weight, and often voids the manufacturer system the salesman named. Ask the AHJ whether overlay is even a path on this roof. Read the current covering-renewal bulletin for this city. We will not restate layer limits. Full tear-off is the usual honest conversation when overlay is not a path.
Material families, not a price list
For a typical single-family house, the ranked conversation is usually:
- Architectural asphalt shingle. Common, fastest crew cycle, coastal salt and inland heat still decide product and flashing metal.
- Concrete tile, new. Heavier, more labor, more flashing. The sheet under the tile is the waterproofing.
- Clay barrel. Same geometry, different material cost and matching rules, especially in Covenant and coastal Spanish stock.
- Lift-and-relay. Existing tile reused, new sheet. Often the value path when the field is still sound. See tile roof lift and relay and tile roofing.
- Standing seam. Metal roofing. Finish and fastener spec matter on the coast.
- Stone-coated steel. Tile-look or shingle-look steel, still a metal system.
- Low-slope TPO or similar. Flat TPO on the flat sections only, quoted on that area, not on the whole house’s living square footage.
Clay costs more than concrete on the same squares. Standing seam costs more than stone-coated on the same squares. Those are rank-order facts, not invoices. We will not invent installed totals, per-square-foot TPO rates, or Class 4 adders.
What every San Diego quote should line-item
If a page just says “new roof” and a lump sum, ask for columns:
| Line | Why it matters |
|---|---|
| Roof area in squares | Living area is not roof area |
| Tear-off versus lift-and-relay | Different labor, different deck access |
| Deck repair allowance | Rot shows after tear-off |
| Ice-and-water at valleys, eaves, penetrations | Warranty and leak path |
| Field underlayment, named | The sheet is the waterproofing under tile |
| Drip edge, step flashing, valleys, pipe boots | Boots are a common leak |
| Named field product and hip/ridge | Field shingles cut down are not ridge |
| Who pulls permit and meets the inspector | City or County, not “included” as a vibe |
| Haul-away and magnetic sweep | Dump fees are real |
| Manufacturer enrollment vs workmanship years | Two documents |
Permit fees follow the jurisdiction’s valuation tables. We will not invent a dollar band. Plywood replacement is a per-sheet line the C-39 finds after the old roof is off. We will not invent a sheet price.
What drives the number up or down
Size and complexity. A simple gable is the easy case. Steep pitch, many valleys, dormers, chimneys, skylights, three-story access, and cut-up Mediterranean planes all add labor and flashing. Ask for plane count, not just squares.
Deck. Forty-year houses hide more rot. An allowance is a planning line, not a guarantee of how many sheets you will actually buy.
Underlayment and flashing tier. High-temp synthetic under tile, ice-and-water in valleys, and metal that matches coastal salt versus inland heat change the sheet package. Coastal material logic: best roof material for coastal climates.
Product grade. Class 4 impact-rated shingles, designer shingles, clay versus concrete, standing seam versus stone-coated: each is a specified upgrade. Insurance discounts for impact ratings are carrier-specific. Ask your agent. We will not invent a savings percent.
How to read a shingle bid and a tile bid
On shingle, you should see tear-off, deck allowance, named shingle, matching ridge, flashing, sheet, permit, and warranty enrollment as separate thoughts even if they share a page.
On tile, you should see whether the tile is new or relayed, high-temp sheet, flashing and mortar or ridge detail, and a breakage allowance if existing tile is going back on.
Two bids only compare if the squares and the named products match. A low number that skipped ice-and-water or reused rusty valley metal is not a bargain.
Rebates and financing (check the source)
San Diego does not run a general “new roof rebate.” Narrow cases:
- Cool roof / high-reflectance systems. Usually low-slope or a qualifying cool product. the California energy standards is a California Energy Commission path for this slope and climate zone, not a default on every steep-slope San Diego reroof. Current SDG&E rebate rules change. See cool roof the California energy standards.
- Solar-ready work while the roof is open. Conduit and flashing are cheaper when the field is already stripped. Coordinate with a licensed electrician. We will not invent a solar-prep savings.
- C-PACE on qualifying commercial or mixed-use energy work. Ask during the commercial estimate.
- Financing products (HELOC, Title I, contractor-referred): roof financing options. We do not lend.
Frequently asked questions
How much does a new roof cost in San Diego? It costs whatever the matched C-39 writes for your measured squares, named product, deck, and permit counter. This page will not invent a dollar band. Compare complete scopes.
How long does replacement take? A straightforward shingle house is often a few crew days once materials and permit are in hand. Tile relay runs longer. Steep, cut-up, or wet-deck jobs add days. Weather delays are uncommon relative to other metros, not zero.
Layover or tear-off? Tear-off unless a licensed C-39 writes a specific reason not to, including how they will inspect deck. The first-page savings on a layover are the hidden deck and the warranty.
Are Class 4 shingles worth it? They are a specified product with a different test rating. Whether your carrier discounts them is an insurance question. Ask for that product as a line, not as a blog payback story.
What should I look for in a quote? Squares, named products, deck allowance, who pulls the permit, and two warranties. Verify C-39 at CSLB.
