Roof Replacement Services
A roof replacement from QRS removes your old roof down to the deck and builds a complete new shingle, tile or flat roof system for homes across Los Angeles and Orange County. It starts with a roofer-led free roof evaluation, so the decision rests on your roof’s real condition, not a sales pitch.
When a New Roof Is the Right Call
Replacement makes sense when a roof is worn out as a whole, not in one spot. That looks like shingles gone brittle and bare of granules on every slope, tile and underlayment failing together, or a flat roof carrying patch on top of patch with water reaching the deck. At that stage, each roof repair buys less time than the last. It isn’t the only option for tile, though: when the tiles are still sound and it’s the underlayment that has failed, a tile lift & relay replaces that layer and puts your own tiles back.
A full tear-off takes the roof down to the deck. That lets us check the decking and address soft or damaged sections before building up again with new underlayment, flashings at every wall and penetration, the ventilation or drainage details your roof type calls for, and the new roofing itself. Your written scope lists all of it before work begins, including the material, profile and color you’ve chosen and how any decking damage found under the old roof will be handled. Qualified crews then install the agreed system cleanly and to spec.
Choose Your New Roof
Compare replacement by roof type, see how a lift & relay keeps your tiles, or look at commercial replacement and financing options.
Choosing a Roof for Southern California
Start with the framing
Clay and concrete tile are far heavier than shingles, so a switch to tile depends on whether the structure can carry it. Moving from tile to a lighter roof is usually simpler on that front.
Match the roof to the house
Tile suits Spanish and Mediterranean homes, shingles fit Craftsman and ranch styles, and low-slope sections need a system built to drain, not shingles or tile.
Plan for your exposure
Inland valleys bake roofs in summer heat, coastal homes deal with salt air and the marine layer, and homes near brush face wind-blown embers. Where your home sits shapes the material and detailing we recommend.

Frequently Asked Questions
Straight answers about roof replacement.
How much does a roof replacement cost in Los Angeles?
It depends on your roof: its size, pitch and number of stories, the roofing material, how many old layers come off and whether any decking needs replacing. Tile usually costs the most to install. For a quick estimated range, our Instant Quote measures your roof from satellite imagery. Your actual price comes in a written scope after a free roof evaluation, before any work begins, and financing can spread it into monthly payments.
How long does a roof replacement take?
Most home roof replacements take 3 to 5 days. The roof’s size, the roofing material, any decking repairs and the weather can change that.
Do you pull the permits?
Yes. When your roofing project needs a building permit, we pull it for you.
What are the signs I need a new roof?
Look for wear across the whole roof rather than one problem: shingles that are brittle, curling or shedding granules everywhere, a flat roof membrane worn through in many places, leaks that keep coming back in different spots, or soft decking. Tile is different, because the tiles often outlast the underlayment, so a tile lift & relay may be all you need. A free roof evaluation shows which one you’re dealing with.
Can I finance a roof replacement?
Yes. Roof financing options are available to help spread the cost of your new roof into monthly payments, subject to credit approval. The Instant Quote on this site shows example monthly payments, and your written scope and price come first, so you know exactly what you’re financing.
Do I have to replace the whole roof at once?
Not always. A single section, such as a flat roof over an addition or a detached garage, sometimes wears out well before the rest and can be handled on its own. When the wear is spread across the roof, replacing it all at once is usually the more sensible choice. The roof evaluation photos show which situation you’re in.
How is my yard protected during a tear-off?
We lay tarps to protect your landscaping and catch debris as the old roof comes off, and every job ends with a nail sweep and clean-up. If there’s something close to the house you’re worried about, like a fragile planter or patio furniture, point it out before work starts.
What happens at the end of a roof replacement?
We do a final walkthrough with you, review the finished roof and go over your 10-year workmanship warranty in plain English. It’s also your chance to ask questions and point out anything you’d like us to look at again.
Do you replace roofs on commercial and HOA buildings?
Yes. A commercial roof replacement is planned so the building stays open during the work. HOA and multi-family projects get one point of contact for the whole job.
