Is $30,000 Too Much for a Roof? Inland Empire Prices

Skip to the Answer

Shingle roofs in inland California run about $6 to $9 per square foot, so most shingle jobs land well under $30,000.
New tile roofs in California run about $12 to $21 per square foot, so $30,000 is normal for a tile roof of 1,500 to 2,500 square feet.
Your roof is not the same size as your house. A two story home can have half the roof of a one story home with the same living space.
Many tile roofs in Ontario only need new underlayment, not new tile. That job usually costs far less than a full new tile roof.
Compare quotes line by line. Tear off, wood repair, underlayment, flashing and the permit are where prices split apart.
In California the down payment on a home improvement job cannot be more than $1,000 or 10 percent of the price, whichever is less.

What a New Roof Costs Here, by Roof Type

We look at a lot of roofs in Ontario and the cities around it, and the first question is almost always the same. Somebody got a quote near $30,000 and wants to know if they are being taken. The answer starts with one thing. What kind of roof is it?

Shingle roofs. A California cost guide from RoofingCalc, dated March 30, 2025, puts architectural shingles at about $6 to $9 per square foot installed in inland areas like the Inland Empire, and $7 to $12 near the coast (RoofingCalc). That works out to $12,000 to $18,000 for a 2,000 square foot shingle roof.

Tile roofs. The same guide lists tile at about $12 to $21 per square foot (RoofingCalc). A Connecticut roofer's guide gives clay and concrete tile at $10 to $18 per square foot, or $20,000 to $36,000 for a 2,000 square foot roof (Berkeley Exteriors). Tile is the main roof type on tract homes from Ontario Ranch to Rancho Cucamonga, so this is the range most local owners should look at.

Metal roofs. RoofingCalc puts metal at $9 to $17 per square foot in California, or $13,500 to $25,500 on a 1,500 square foot roof (RoofingCalc).

The national numbers you see first on Google run much lower. NerdWallet cites Angi for an average of $9,500 and a range of about $5,800 to $46,000, or about $4 to $11 per square foot (NerdWallet). That average is pulled down by small shingle roofs in cheaper parts of the country. It tells an Ontario tile owner very little.

Worked example. Typical installed cost by roof size, using RoofingCalc's California ranges (March 2025): architectural shingle at the inland rate of $6 to $9, metal at $9 to $17, tile at $12 to $21 per square foot. Roof size is roof area, not living space.
Roof Size	Shingle	Metal	New Tile
1,500 sq ft	$9,000 to $13,500	$13,500 to $25,500	$18,000 to $31,500
2,000 sq ft	$12,000 to $18,000	$18,000 to $34,000	$24,000 to $42,000
2,500 sq ft	$15,000 to $22,500	$22,500 to $42,500	$30,000 to $52,500
3,000 sq ft	$18,000 to $27,000	$27,000 to $51,000	$36,000 to $63,000

When $30,000 Is Fair and When It Is High

Put the table above next to your quote. We read it as worked examples built from the cited per square foot ranges.

$30,000 is high for a shingle roof under about 3,000 square feet. At the inland range of $6 to $9, even a 3,000 square foot shingle roof tops out near $27,000 (RoofingCalc). A shingle quote above that needs a reason in writing, like a lot of rotten wood, a very steep pitch or two old layers to tear off.

$30,000 is fair for a new tile roof of about 1,500 to 2,500 square feet. At RoofingCalc's California tile range of $12 to $21 per square foot (RoofingCalc), a 2,000 square foot tile roof runs $24,000 to $42,000. A quote of $30,000 sits in the low half of that range.

$30,000 can be too much for the job you need. Many Ontario tile roofs from the 1980s and 1990s still have good tile. The weak part is the paper under it. If the tile is sound, ask for a price to lift the tile, put down new underlayment and set the same tile back. That is called a re-lay, and it skips the cost of new tile. Our tile roofing page explains how it works.

$30,000 is cheap if the quote is for a new tile roof on a large single story home, or a roof with many hips, valleys and skylights. Very low tile numbers deserve a hard look at what was left out.

What a 2,000 Sq Ft Roof Costs by Type

Shingle, inland rate$12,000 to $18,000
Metal$18,000 to $34,000
New tile$24,000 to $42,000

Your Roof Is Not Your House Size

Most cost guides price by roof size, and most owners know their living space. Those are two different numbers. NerdWallet makes the same point, that your roof size may differ from the square footage inside your home (NerdWallet).

Take a 2,000 square foot one story house covers about 2,000 square feet of ground. Add a 4 in 12 pitch, which adds about 5 percent, and eaves that hang past the walls, and the roof is often 2,300 square feet or more. Now take a 2,000 square foot two story house. Its footprint is closer to 1,000 square feet, so the roof may be only 1,200 to 1,300 square feet.

Same living space. Close to half the roof. That is why two neighbors with the same size homes can get quotes $10,000 apart and both be fair. Roofers count in squares, and one square is 100 square feet. Ask every roofer how many squares they measured. If the numbers are far apart, someone measured wrong.

What Pushes a Roof Price Up in the Inland Empire

Labor. Labor is the biggest part of most roof bills. NerdWallet says it is more than half for most owners (NerdWallet). Berkeley Exteriors puts it at 40 to 60 percent (Berkeley Exteriors). Tile is slow, heavy work, which is a big reason tile costs more.

Pitch and shape. A steep roof can add $1,000 to $3,000, per NerdWallet (NerdWallet). Hips, valleys, chimneys and skylights all add flashing and time.

Tear off and wood. Removing extra layers adds about $1 to $2 per square foot, and spot repairs to the roof deck run about $2 to $4 per square foot in California, per RoofingCalc (RoofingCalc). Nobody knows how much wood is bad until the old roof is off. A good quote says how wood repair will be priced.

Cool roof rules. California's energy code covers re-roofs where more than half the roof is replaced. For steep roofs in climate zones 10 to 15, the new roofing must meet an aged solar reflectance of at least 0.20 and a thermal emittance of at least 0.75, or an SRI of at least 16, unless an exception applies (California Energy Commission). Look up your address on the Energy Commission's climate zone tool to see which zone your home is in. Cool rated products are common, but they can limit color choices.

Permits. RoofingCalc lists California roofing permits at about $200 to $800 (RoofingCalc). The City of Ontario now offers a streamlined online permit for detached single family re-roofs through its Symbium portal (City of Ontario). Your quote should say who pulls the permit and that it is included.

How to Check a $30,000 Roof Quote

Get at least three written quotes for the same scope. Then line them up using the checklist below. The goal is to compare the same job, not three different jobs with three different prices.

Watch the down payment. Under California law, the down payment on a home improvement contract cannot be more than $1,000 or 10 percent of the contract price, whichever is less. Payments after that cannot run ahead of the work done (CSLB). On a $30,000 roof, that means no more than $1,000 up front. Walk away from a roofer who wants $10,000 before the job starts.

Check the license. The contract should list the contractor's license number, address and a completion date (CSLB). Look the number up on the CSLB site before you sign.

Ask for photos. A roofer who walked your roof can show you the cracked tile, torn paper or soft wood they are pricing. If the quote is for a full replacement, ask why a repair or a re-lay will not do. A roof inspection with photos settles that question before you spend $30,000.
