Shingle Roof Replacement in Rialto from $6. Composition in a climate that is hard on it, torn off rather than layered over. Free inspection and a written quote.
Composition here ages faster than its warranty implies, because warranties are written for an average American climate and zone 10 is not one. Judge the roof by its condition rather than its paperwork: granule loss and brittleness show up years earlier here than the same product would manage on the coast.
Composition shingle in zone 10 ages faster than the warranty suggests, because warranties are written for an average American climate and this is not one. Expect granule loss and brittleness to show earlier here than the same product would on the coast, and judge a roof by its condition rather than its paperwork.



Composition shingle runs about $6 to $9.50 per square foot in the Inland Empire -- below the roughly $8.50 typical in Los Angeles and well above the $4 national figure. Judge the roof by condition rather than warranty, because zone 10 ages a covering faster than the paperwork assumes. The question that moves a Rialto quote most is one almost nobody asks: does an exception already apply to your house. R-20 attic insulation, a radiant barrier or sealed ducts each exempt you from the steep-slope cool-roof requirement, and checking costs nothing.
A single-layer tear-off onto sound plywood, a simple roof, and a color whose aged rating is comfortably compliant.
A second or third existing layer, skip sheathing, a steep pitch, or a dark color that needs a premium product to meet the aged minimum.
Ventilation. On a roof this exposed, poor attic ventilation will cook the next covering as fast as it cooked the last.
Heat is the local enemy and it does not arrive as an event. Sustained zone 10 sun and thermal cycling take the plasticiser out of asphalt and the felt out from under tile, so roofs here reach the end of their lives years before the warranty suggests -- and the cool-roof requirement that most of Los Angeles escapes applies here in full.
Rialto is Title 24 climate zone 10, which is why the steep-slope cool-roof requirement applies to a pitched roof here and generally does not in the Los Angeles basin.
An overlay -- new shingles nailed over the old ones -- is legal up to a limit and is a bad idea in this heat. Two layers hold more heat than one, the deck cannot dry, and the new covering ages faster on top of the old. It also hides the sheathing, which is the one thing a survey most needs to see.
This is a replacement company saying so. In this climate the most expensive mistake is buying the whole roof when the job was the felt underneath it.
A slipped course, a perished boot, a flashing that has let go: repairs, in the hundreds. Whether the roof is finished is decided by the covering away from the failure, and that is a separate thing to go and look at.
If the complaint is an unbearable upstairs rather than a leak, attic insulation and ventilation will usually do more than a new covering -- and it happens to exempt you from the cool-roof requirement as well.
We will say so when it is, and it is the same piece of advice as the opposite one: worth nothing unless you are shown what it rests on.
The thing that separates a Rialto replacement from a Los Angeles one is the energy code.
In Rialto this is not an upsell, it is the code.
Age the felt, not the tile.
Low slope carries the strictest cool-roof requirement in the state -- aged SRI 75 or better, in all sixteen zones with no exemption, on the same 50% trigger.
In zone 10 the 50% line decides more than it does elsewhere in the state.
Newest subdivisions, busiest geometry, plywood decks.
Its own city, its own building department.
Unincorporated. County permits, and more than one roof.
The oldest stock here. Check the deck first.
A century of building ages in one city.
Semi-rural, unincorporated, outbuildings everywhere.
Canyon country. Brush interface and county permits.
The questions that come up, before you have to ask.

It can. The requirement is on the aged solar reflectance in the CRRC listing, and the darker end of most ranges is where it gets marginal. Pick the color you want, then check its listing rather than assuming.
Typically $9,000 to $22,000. The Inland Empire sits below the Los Angeles basin on labor and above the High Desert, so an LA average reads high here and a national average reads low. Composition runs about $6 to $9.50 per square foot, tile considerably more.
Probably yes, and this is the main way Rialto differs from Los Angeles. Rialto is Title 24 climate zone 10, and the steep-slope cool-roof requirement applies in zones 10 through 15 -- so your pitched roof is in scope once you replace 50% or more of it. The minimum is aged solar reflectance 0.20 and thermal emittance 0.75, or SRI 16.
It is the product's performance after weathering, not when new, and it is the only figure Title 24 accepts. The Cool Roof Rating Council tests at three-year exposure sites because a shingle that leaves the factory at 0.35 can age to 0.22. If a quote cites an initial reflectance, it is citing the wrong number.
Free inspection, and a written quote against a written scope. Aged ratings quoted from the CRRC listing, never initial ones.
