Every replacement we sell is a full tear-off, not a layover. That means you get new underlayment, new flashing, and a clean look at the decking underneath. Here is what is standard on our scope, and what we quote separately only when your roof actually needs it.
We strip the old shingles, tile, or metal down to the sheathing and haul it off in our own dumpsters. No layovers, no trapping old leaks under a new layer. A typical 2,000 square foot roof produces three to five tons of debris, and it all leaves with us.
Every square foot of plywood gets checked for rot, delamination, and loose nails. We replace damaged sheathing at a quoted per-sheet price so you see the cost before we install it. Soft spots around chimneys and valleys are the most common finds.
We install roofing felt or synthetic underlayment across the whole deck, then new flashing at valleys, walls, pipes, and chimneys. Flashing is where most California roof leaks start, so we do not reuse old metal even if it looks fine from the ground.
Ridge vents, intake vents, and proper attic airflow keep your roof deck cooler and your shingles lasting longer. We size the ventilation to the attic square footage, not to whatever box was on the truck. New ridge caps finish the peak and lock down the edges.
We pull the re-roof permit, post it, and meet the inspector on site. You get the signed-off permit card and photos of the deck and finished details. That paperwork matters at resale and when your insurance company asks for proof of roof age.
Roof Replacement in California is the full tear-off of your existing roof covering, inspection and repair of the deck and underlayment, and installation of a new code-compliant roof system. We pull the old asphalt shingles, clay tiles, or metal panels down to the sheathing, replace any rotted plywood, then build back up with roofing felt, flashing, ridge vents, and your chosen finish. Most homes get 15 to 30 squares of material, which is roughly 1,500 to 3,000 square feet of roof surface.
California roofs take a beating that roofs in milder states never see. UV exposure bakes shingles until they curl and crack, Santa Ana winds rip at ridge caps, and winter rain finds every cracked flashing detail. That is why we treat every job as a system, not a shingle swap. If you have been searching for a California roof replacement contractor near me, we cover the whole state with crews who know Title 24 Energy Code and California Building Code (CBC) requirements before we ever load a dumpster.
We keep it simple: one walkthrough, one written scope, one crew on your roof until the job is done. Here is what the week looks like from your side of the driveway.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Tools & EquipmentRoofing nail gun
Sets shingle nails at the correct depth and angle so they hold without cutting through the mat. We adjust pressure per material, because clay tile and asphalt shingles need different settings.
Shingle cutter and pry bar
Cuts clean edges at hips and valleys and lifts old shingles without tearing up the decking underneath. Clean tear-off means fewer surprises when we inspect the sheathing.
Chalk line and utility knife
Snaps straight courses so the shingle lines stay true across the whole roof. Crooked courses are the fastest way to spot a rushed install from the street.
Roofing safety harness and ladder stabilizer
Keeps every crew member tied off and every ladder footed on uneven ground. Steep California roofs and two-story drops are not places for shortcuts.
Nail magnet
Sweeps the lawn, driveway, and flower beds for stray nails at the end of each workday. It is the difference between a clean yard and a flat tire.
Caulking gun
Applies roof sealant at pipe boots, counterflashing, and any penetration. We use high-temp sealant that will not run in a 100-degree summer.
GAF Master Elite installation standards
As a GAF Master Elite contractor, we install to the manufacturer's spec so the enhanced warranty actually applies. That means the right number of nails per shingle, correct starter course, and approved ventilation. Skip any of those and the warranty is void.
Title 24 Energy Code compliance
California requires cool-roof and insulation values that meet Title 24. We select shingles and underlayment that meet the reflectivity requirements for your climate zone, and we document it for the permit file.
California Building Code (CBC) flashing details
CBC sets the minimum flashing heights, valley construction, and fastening schedules. We build to code on every job, which is why our roofs pass inspection the first time instead of getting red-tagged.
Balanced attic ventilation
We calculate intake and exhaust vent area against attic square footage, then install ridge vents and soffit vents to match. Balanced airflow keeps the deck cooler and stops condensation from forming on the underside of the sheathing.
01
What we do: We inspect the deck, underlayment, and flashing, then quote a full tear-off with asphalt shingles or an upgrade to metal. You get one fixed price and a permit handled for you.
→ A new roof with a 25 to 50 year material warranty, no more spring leak calls, and a documented roof age for insurance and resale.
02
What we do: We do a fast inspection, provide a written report with photos, and can schedule the replacement around your escrow timeline. Most jobs close out in under a week.
→ A signed-off permit, a transferable warranty, and one less negotiation point holding up the sale.
03
What we do: We tarp and stabilize first, then assess whether the damage is repairable or whether the whole roof is done. You get photos and a written scope either way.
→ Water stops coming in immediately, and you have the documentation your insurance adjuster needs to process the claim.
04
What we do: We inspect the drainage, check the deck for sag, and install a new TPO membrane, EPDM membrane, or modified bitumen system with proper slope and drains.
→ Standing water drains instead of sitting, the membrane stops bubbling, and the ceiling below stays dry through the rainy season.
California is not one climate, and we do not roof it like one. Coastal homes in Culver City and Santa Monica deal with salt air and morning fog that corrodes flashing and eats at fasteners. Inland roofs in Rancho Cucamonga and Hesperia see 100-degree summers that bake shingles from the top down and push attic temps past 140 degrees. Bay Area cities like Mountain View and Pleasanton get winter rain that finds every cracked pipe boot. We match the material to the zip code: cool-roof shingles and upgraded ventilation inland, corrosion-resistant flashing and fasteners near the coast, and heavier underlayment where rain totals run higher. Every job pulls a local permit and meets Title 24 Energy Code and California Building Code (CBC) requirements. If you are weighing a full roof replacement California wide, the honest answer is that the right system depends on where you live, and we quote it that way.
Chatsworth
Hot valley summers and wind-driven dust mean we spec reflective shingles and check ridge caps closely. Many homes here have 20-year-old builder-grade roofs ready for replacement.
Fullerton
Older housing stock with original sheathing and mature trees. We plan for extra deck repair and gutter clearing because shade keeps roofs damp longer here.
Pleasanton
Tri-valley heat and winter rain both hit hard. We install heavier underlayment and verify attic ventilation, since many two-story homes here run hot upstairs.
Irvine
HOA-heavy neighborhoods with strict color and material approvals. We handle the submittal paperwork so your replacement matches the community standard.
Hesperia
High Desert wind and UV exposure are brutal on shingles. We use high-wind nailing patterns and inspect every ridge and hip for lifted material.
Summer attic temperatures above 140 degrees inland
Shingles cook from underneath and fail years early. We size ridge and intake ventilation to the attic square footage so hot air actually escapes instead of sitting on the deck.
Santa Ana and desert wind events
Lifted edges and missing ridge caps are common after a wind event. We nail to the high-wind schedule and use enhanced starter courses on exposed ridges and hips.
Coastal salt air and fog corrosion
Fasteners and flashing rust faster near the coast. We spec corrosion-resistant metal and seal every penetration with high-temp roof sealant that holds up to salt air.
Winter rain concentrated between November and March
Most of the year's water arrives in a few months, so a small flashing leak becomes a big one fast. We dry-in the same day we strip and schedule around storm windows.
Most roof failures start small and stay invisible until water is already inside the house. These are the calls we get most often across California, and what happens if you let them ride.
Problem
Exposed underlayment dries out and cracks, and the next wind event peels whole sections off. Once water reaches the decking, rot spreads fast and turns a roof job into a framing repair.
Our Fix
We tear off the failed field, replace any soft decking, and install new shingles rated for California sun. If the damage is isolated, we will tell you a repair buys you time. If it is widespread, a full roof replacement California homeowners can finance is the cheaper long-run call.
Problem
A cracked boot can dump water straight onto insulation and ceiling drywall for months before you notice a stain. By then you are replacing insulation and repainting, not just resealing a boot.
Our Fix
We replace every pipe boot, valley metal, and wall flashing during a replacement, and we seal them with roof sealant rated for high heat. If you are not ready for a full roof, we can reflash the problem areas and buy you a season or two.
Problem
Backed-up gutters rot the fascia and push water under the bottom course. A hot attic bakes shingles from underneath, cutting their life by years and driving up your cooling bill.
Our Fix
We clear and re-hang gutters, then balance intake and ridge ventilation so hot air actually leaves the attic. On replacements, we size the vents to the attic square footage and verify airflow before we close up the ridge.
Problem
Raccoons tear at ridge vents, hail bruises shingle granules, and wind lifts edges. Left alone, each of these becomes a water entry point and a reason for your insurer to non-renew.
Our Fix
We document the damage with photos, tarp what needs tarping, and give you a written scope. If the roof is at the end of its life, we handle the full replacement and the permit. If it is repairable, we repair it and tell you when to expect the next problem.
A new roof is not just curb appeal. It stops water intrusion, cuts cooling costs, and protects the structure underneath. Here is what you actually gain when you replace roof California style, with materials rated for our climate.
Stop Chasing Leaks
One missed nail pop or cracked flashing can send water into your attic for months before you see a ceiling stain. A full tear-off lets us inspect every square foot of decking and replace the rot before it spreads. Most leak callbacks we see come from patch jobs over failed underlayment, not from the shingles themselves.
Cut Summer Cooling Bills
Aged, dark shingles absorb heat and push attic temperatures past 140 degrees. We install reflective asphalt shingles and ridge vents that move hot air out and pull cooler air in. Homeowners in Rancho Cucamonga and Hesperia routinely report their upstairs rooms are 8 to 12 degrees cooler after a roof replacement services California project.
Pass Inspection and Insurance
Many California insurers now require a roof inspection before they will renew a policy on a home older than 20 years. A documented replacement with permit sign-off gives you a paper trail. We provide photos of the deck, the underlayment, and the final flashing details so your agent has what they need.
Add Real Resale Value
A new roof is one of the few home improvements that appraisers can measure. Depending on the material, you can recoup 60 to 70 percent of the cost at sale. Buyers in Irvine and Pleasanton ask for the roof age first, and a recent full roof replacement California record answers that question before they ask it.
Typical 2026 pricing in California runs $9,000 to $28,000 for a full tear-off and replacement on a single-family home, or roughly $450 to $900 per square installed. Asphalt shingles land at the low end; clay tile, concrete tile, and standing-seam metal at the high end. Two-story homes, steep pitches, and hidden deck rot add cost. We give you a fixed written price after the inspection, so the roof replacement cost in California per square foot is settled before we start, not after.
Typical Investment Range
$9,000 - $28,000 depending on size, material, and deck condition
A new roof protects everything under it: framing, insulation, drywall, and your belongings. Compared to repairing water damage and replacing soaked insulation, the replacement is the cheaper path. You also get a transferable warranty that adds real value at resale.
What changes the price
Roof size and pitch
Square footage drives material and labor more than anything else. A steep pitch slows the crew down and requires more safety rigging, which adds labor hours. A 1,500 square foot roof and a 3,000 square foot roof can differ by $10,000 or more.
Material choice
Asphalt shingles are the budget option. Clay tiles, concrete tiles, and standing-seam metal roofing panels cost two to three times more installed but last decades longer. We quote all three so you can see the trade-off in real numbers.
Deck condition
Soft or rotted plywood has to be replaced before the new roof goes on. We quote a per-sheet price and photograph every bad section. Most homes need zero to four sheets, but water damage around chimneys can push that higher.
Layers to remove
A roof with two or three old layers takes longer to strip and costs more in disposal. If a previous contractor did a layover, we have to tear off both layers to inspect the deck properly.
Flashing and penetrations
Every chimney, skylight, and vent adds detail work. Complex rooflines with multiple valleys and dormers take more labor and more flashing material. Simple gable roofs cost less to do right.
Permits and local fees
California cities charge different amounts for a re-roof permit, and some require a final inspection. We include the permit in the quote so there is no surprise line item after the job.

Tore off 24 squares of old shingles and installed new Owens Corning Duration in three days. They found two soft spots in the deck and showed me photos before replacing the plywood. Yard was spotless. Upstairs is cooler already.
Yelp ★★★★★4.8
We had a leak around the chimney after the last storm. RoofPros tarped it the same day and came back with a full replacement quote. They handled the permit and the inspection. No surprises on the final invoice.
BBB ★★★★★4.9
Third bid we got and the only one that went into the attic to check ventilation. They explained why the ridge vent mattered instead of just selling us shingles. Four days start to finish and the cleanup was better than the other crews left it.
Google ★★★★★5.0
Flat garage roof was ponding and bubbling. They replaced the decking, fixed the slope, and installed TPO membrane. It has rained twice since and the garage is bone dry. Fair price and they showed up when they said they would.
Our roof replacement services California wide reach from the San Fernando Valley to Orange County, the Inland Empire, the Bay Area, and the High Desert. Each city has its own inspection quirks, climate pressures, and material preferences, and our foremen know them. Here are a few of the communities where we install roofs every week.
Hot valley summers and wind-driven dust make reflective shingles and tight ridge caps the right call. Many homes here are on their original 20-year roof and ready for a full tear-off.
Dense single-family housing with a lot of 1950s and 1960s construction. We plan for extra deck repair and work around narrow driveways where material staging is tight.
Wind exposure off the foothills means high-wind nailing patterns and reinforced starter courses. We check every ridge and hip after a Santa Ana event.
Older valley homes with mature trees that keep roofs damp and drop debris. We clear gutters, inspect for rot, and install shingles rated for the summer heat.
HOA communities with strict material and color approvals. We handle the submittal paperwork so your replacement matches the neighborhood standard the first time.
Two-story homes with hot upstairs rooms. We balance attic ventilation and install cool-roof shingles that meet Title 24 for the local climate zone.
Coastal-influenced heat and winter rain. We spec corrosion-resistant flashing and heavier underlayment because moisture hangs around longer here than inland.
Inland Empire heat bakes shingles from the top down. We install reflective asphalt shingles and ridge vents sized to the attic square footage.
Older housing stock with original sheathing and lots of shade trees. We budget for deck repair and gutter clearing on nearly every job here.
Windy, exposed lots where ridge caps take a beating. We nail to the high-wind schedule and use enhanced starter courses on every hip and ridge.
High Desert UV and wind are brutal on shingles. We use high-wind nailing patterns and inspect every ridge and hip for lifted material after install.
Mix of older and newer roofs near the foothills. We quote asphalt and standing-seam metal side by side so homeowners can weigh cost against lifespan.
Bay Area winter rain finds every cracked pipe boot. We replace all flashing and boots during a replacement and verify attic ventilation before we close the ridge.
Tri-valley heat and rainy winters both hit hard. We install heavier underlayment and check ventilation on two-story homes that run hot upstairs.
Hillside homes with complex rooflines and multiple valleys. We take extra time on flashing details because that is where most leaks start on these layouts.
Real answers to the questions we hear most often from local homeowners and property managers.
New construction and additions need a roof built from the deck up. We install the same systems we use on replacements, so your new build starts with proper underlayment, flashing, and ventilation instead of shortcuts.
View Roof InstallationNot every roof needs a full tear-off. If you have missing shingles, a cracked pipe boot, or storm damage in one area, we repair it and tell you honestly how many years that buys you before replacement makes more sense.
View Roof RepairLeaks rarely start where the stain shows up. We trace water back to the source, whether that is cracked flashing, a failed valley, or a nail pop, and seal it. If the leak is a symptom of a dead roof, we will say so.
