Shingle Roof Replacement · TotalShield®
A shingle roof replacement removes your old roof down to the deck and installs a complete new system: underlayment, flashings, balanced attic ventilation and new shingles, built to the manufacturer’s requirements. QRS replaces shingle roofs across Los Angeles and Orange County with our TotalShield® Shingle System, starting with a free roof evaluation.
Overview
Asphalt shingles give up a little ground every summer. Southern California sun breaks down the asphalt, the granules that shield it wash into the gutters, and the shingles grow brittle, then curl or cup at the edges. Once that wear is spread across the whole roof, repairs turn into a chase from one leak to the next. A full tear-off ends the chase: we remove the old shingles and underlayment down to the deck, check the decking for soft or damaged spots and build the new roof from the bottom layer up.
A new roof is also the time to fix what the old one got wrong. We plan balanced attic ventilation, with intake low at the eaves and exhaust near the ridge, because heat trapped in the attic shortens shingle life. Flashing at walls, chimneys and skylights is part of the plan too, since that’s where many shingle leaks begin. If your roof isn’t at that point yet, a shingle roof repair may be enough, and a free roof evaluation will tell you which way to go.

How a shingle roof replacement works
Roof Evaluation and photos
A roofer inspects the roof, photographs the wear and tells you plainly whether replacement is the right call.
- Granule loss, curling and brittleness
- Flashings, valleys and penetrations
- Attic intake and exhaust vents
Clear quote and shingle choice
You pick the shingle style and color, then get a written scope and price for the full system before any work begins.
Tear-off and deck check
We protect your landscaping, strip the old roof down to the deck and look for soft, delaminated or damaged decking while it’s exposed.
- Old shingles, nails and underlayment removed
- Decking checked and photographed
- Debris hauled off as we go
New shingle system installed
The new layers go on in order, each one lapped so water sheds over the layer below it.
- Drip edge and underlayment
- Starter strips at eaves and rakes
- Shingles with step flashing at walls
- Pipe boots, vents and ridge caps
Clean-up and final walkthrough
Once the site is clean, we review the finished roof with you and share photos from each stage of the job.

Frequently Asked Questions
Straight answers about shingle roof replacement.
How much does a shingle roof replacement cost?
It depends on the roof’s size, pitch and number of stories, the shingle line you choose, how many old layers come off and whether any decking or ventilation needs work. Our Instant Quote gives you a quick estimated range from satellite measurements of your roof, and your written scope and price come after a free roof evaluation, before work begins.
How long does a shingle roof replacement take?
Most home roof replacements take 3 to 5 days, depending on the roof’s size, any decking repairs and the weather.
Do you pull the permits?
Yes. When your roofing project needs a building permit, we pull it for you.
Can you install new shingles over my old roof?
We do full tear-offs. Removing the old shingles lets us check the deck, replace worn flashings and give the new shingles a flat, clean surface to lie on. Layering over an old roof hides problems you’d want to know about.
What signs mean my shingle roof needs replacing?
Widespread granule loss, curling or cupping across whole slopes, shingles that crack when lifted and leaks in more than one place all point that way. One or two damaged areas usually call for a repair instead, and the roof evaluation photos show which you’re dealing with.
How should I get ready for a roof replacement?
Move cars out of the driveway, take mirrors and pictures off walls that may shake during tear-off, and cover anything stored in the attic, since dust can sift through the deck. Keep pets and kids clear of the work area, and leave protecting the landscaping and cleaning up to us.
What if the decking underneath is soft or damaged?
Your written scope includes a standard allowance for deck repair, so ordinary soft spots are already covered. If we find damage beyond that allowance, we’ll show you in photos and give you the price before replacing anything further.
How do I choose a shingle color?
Look at the whole house, so the roof works with your stucco, trim and any stone. Lighter blends tend to stay cooler in direct sun, which is worth weighing on hot inland streets in Burbank or Anaheim, while multi-tone blends bring out the depth of architectural shingles. Viewing a full-size sample outside in daylight gives a truer read than a small swatch indoors.
