Roof Replacement in San Fernando: What It Costs and How We Handle the Hidden Work
A full roof replacement in San Fernando typically runs $11,000 to $24,000 depending on tear-off depth, decking condition, and material choice. Most jobs on the 1950s and 60s tract homes off Maclay Avenue and San Fernando Road land between $13,500 and $18,500 once decking repairs and code upgrades are factored in. We give you a written line-item estimate before any work starts, and we walk you through exactly what the inspector will flag so the quote doesn’t move on you.
Koreatown Roofing does roofing only. We don’t run a plumbing truck or a painting crew. When you call (866) 974-2271, you get Manny Cordero and a team that tears off and installs roofs in San Fernando every week, not a generalist squeezing your job between a kitchen remodel and a patio pour.
Key Takeaways for San Fernando Homeowners
- Expect two or three layers of old roofing on original 1950s – 60s homes, which drives tear-off cost and dumpster needs.
- Summer heat above 100°F bakes shingles brittle and splits flashing seals, so replacement scopes here skew heavier than coastal LA.
- Permits on older San Fernando homes often trigger decking, ventilation, and strapping upgrades you should see in writing before demo starts.
- We work with GAF, Owens Corning, and Boral among seven manufacturers, so you’re picking material based on your roof and budget, not our inventory.
- Every estimate is free and line-itemed. Call (866) 974-2271 and we’ll come out to 91340 or 91341 and measure it properly.

Fast, Reliable Roof Replacement Across San Fernando
We work the San Fernando neighborhoods between the 5 and the 210 every week, from the older blocks around San Fernando Road up to the hillside-edge streets near Shadow Hills. When a homeowner near Maclay Avenue or a landlord off Truman Street calls us about a roof that’s hit the end of its life, we’re usually on it within a few days for the estimate and scheduling the tear-off within a few weeks. That speed matters here because the heat doesn’t wait, and neither do the leaks once the rainy season hits.
San Fernando is a tight, older city incorporated back in 1911 and largely built out by the 1950s and 60s. That means we know what we’re going to find before we even set the ladder: compact lots, narrow side yards, original wood-shake roofs buried under two or three layers of shingle, and decking that’s been cooking in Valley heat for sixty years. Call (866) 974-2271 and you’ll talk to someone who knows the difference between a Sylmar-era bungalow and a 1963 tract house, because we’ve torn both open.
Why Koreatown Roofing Is San Fernando’s Preferred Roof Replacement Company
We’re a roofing-only contractor, which means 100% of what we do is inspect, repair, or replace roofs. When you hire us for a Roof Replacement in San Fernando, the crew on your roof is our crew, trained on tear-offs and decking and flashing, not a subcontractor’s rotating labor pool.
Manny Cordero runs the company with a neighborhood-accountability mindset. If we do a roof on Hewitt Street, the homeowner’s neighbors see our trucks, watch the job, and ask who’s doing the work. That’s the reputation model we’ve built on, and it’s why we don’t cut corners on decking, underlayment, or cleanup. San Fernando homeowners talk, and we want the next call to come from someone who watched our crew work and liked what they saw.
We also give you real material choice. Most roofing companies push one brand because that’s who they have an account with. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we’ll match the product to the heat and UV load your specific roof carries, not to whatever is sitting in our yard.
Roof Installation in San Fernando
Roof Installation in San Fernando means a complete new roofing system on a home that’s being built, added onto, or completely re-decked. On the newer infill homes and second-story additions around the city, we’re installing from bare sheathing up; on older homes where decking has failed from heat and trapped moisture, the job becomes a full re-install once the old layers come off.
A new roof installation on a typical San Fernando home runs $14,000 to $22,000 depending on square footage, slope, and whether we’re tying into existing framing or working with fresh framing from a general contractor. New construction installs on additions and ADUs around 91340 and 91341 tend to land in the $9,000 to $16,000 range because the decking is new and the access is cleaner.
Full System Install
We strip to the deck, inspect every sheet, replace what’s rotted or delaminated, then install underlayment, flashing, and the shingle or tile system you’ve chosen from our seven-brand lineup. On San Fernando homes with existing skip-sheathing, we almost always lay new plywood or OSB because the old 1×6 boards won’t meet current fastening requirements.
Ventilation goes in on install, not as an afterthought. Ridge vents and intake vents sized to your attic’s square footage matter more in a city where summer attic temps hit 140°F and bake shingles from underneath.
Decking Replacement Before Install
If the decking is shot, the install doesn’t start until it’s replaced, and that’s a line item you approve in writing. We don’t tear off layers, find rotted plywood, and then tell you the price just went up. Manny walks the job with the homeowner before we open anything, explains what we expect to find, and the contract has an allowance for decking so there are no surprises.
Roof Replacement Contractor in San Fernando
Roof Replacement Contractor work in San Fernando is different from anywhere else in the Valley because the tear-off is rarely one layer. The 1950s and 60s tract homes off Maclay and San Fernando Road often have a wood-shake roof under two layers of asphalt shingle, and some have had a fourth layer of rolled roofing added over trouble spots. That’s three or four tear-off passes, extra dumpster volume, and more hours before the first new shingle lands.
A roof replacement contractor who hasn’t worked San Fernando will bid it like a simple single-layer tear-off, then hit you with a change order when the shake layer appears. We know to look for it, we walk the roof before quoting, and our line-item estimate includes the tear-off depth we actually expect. Typical full replacement on these homes runs $13,000 to $19,000, and the decking allowance is built into the contract, not discovered later.
Tear-Off Depth and Staging
On a 1958 ranch house near Maclay Avenue, our crew opened the roof to find three layers of shake and a layer of 30-pound felt glued to skip-sheathing that had dried and split from decades of 100°F summers. We replaced the decking with new plywood, installed a GAF ice and water shield in the valleys and along the eaves, and finished with architectural shingles and a ridge vent. Then added a written change order for the decking before we nailed a single shingle.
That’s how we work every San Fernando job. The estimate names what we expect, and if the tear-off reveals something different, you see it in writing, with a price, before we touch it.
Permit-Triggered Upgrades
When we pull a permit for a roof replacement in San Fernando, the inspector checks more than the shingles. Older homes often get flagged for missing rafter ties, undersized framing at the ridge, or ventilation that doesn’t meet current code. Those upgrades go into your contract as allowances or specific line items, so the permit process doesn’t turn into a second bill you didn’t see coming.
Trusted Brands We Service in San Fernando
Your roof, your material choice. We install products from seven manufacturers, including GAF, Owens Corning, and Boral, and we’ll talk through the tradeoffs honestly. GAF Timberline architectural shingles hold up well under San Fernando’s UV load and come with some of the strongest wind ratings in the class. Owens Corning Duration shingles offer good granule adhesion for homes where heat is the main killer. Boral tile is a smart match for the Spanish-style homes and newer infill builds around the older bungalow streets, and it shrugs off heat better than any asphalt product. We order per job for San Fernando customers, which means no warehouse leftovers being pushed on your roof.

AfterCommon Roof Replacement Problems We See in San Fernando Homes
- Brittle, heat-cracked shingles that granulate and curl. Decades of 100°F-plus summers bake the oils out of asphalt shingles until they split, lose granules, and start leaking only when the concentrated rainy season storms hit.
- Multiple shake and shingle layers trapping moisture against the decking. The original wood-shake roofs on these 50s and 60s tract homes were often roofed over twice without a tear-off. That stack traps heat and moisture against the deck, accelerating rot and making the eventual replacement deeper and more expensive.
- Dried-out original flashing around chimneys and vent pipes. Heat cycling separates the old metal flashing seals, and the first wind-driven rain of winter pushes water straight into the attic. Flashing failure is the number one source of interior leaks we trace on Roof Replacement in San Fernando callouts.
- Compact lots that make staging genuinely hard. Narrow alleys and zero-lot-line setbacks along the older streets off Maclay and San Fernando Road leave little room for a dumpster or ladder setup, which is why we plan staging before the tear-off starts, not after.
Pricing for Roof Replacement in San Fernando, CA
A typical single-story asphalt shingle replacement in San Fernando runs $11,000 to $16,000. A two-story home or one with a steep pitch and limited access lands at $18,000 to $24,000.

Decking replacement adds $900 to $1,800 per 1,000 square feet when rot or skip-sheathing forces it, and most older San Fernando homes need at least partial decking.

FAQs About Roof Replacement in San Fernando
California building code allows no more than two layers of asphalt roofing, but many San Fernando homes built in the 1950s and 60s already carry three or four layers including the original wood shake. A full tear-off is required the moment you’re beyond two layers, and we’ll strip to the deck on most of these older tract homes before installing new underlayment, flashing, and shingles. Call (866) 974-2271 and we’ll check your roof’s layer count during the estimate.
We install GAF, Owens Corning, Boral, CertainTeed, IKO, Atlas, and Tamko. For San Fernando’s sustained 100°F summers, we often recommend architectural shingles with high granule adhesion or Boral tile for maximum heat resistance. Your material choice comes from what your roof actually needs, not from what we happen to have in stock, and we’ll show you the differences before you commit.
Pulling a reroof permit in San Fernando gives the inspector authority to require decking replacement, ventilation upgrades, rafter tie additions, or strapping improvements that bring the roof structure up to current code. These items go into your written contract as allowances or line items before we start, and if the inspector flags something mid-job, we price it for you in writing before any additional work happens.
Yes, in most cases we stage the dumpster at the curb or in a driveway with permits arranged through the city. Lots along the older streets near Maclay and San Fernando Road are tight, and we plan the dumpster drop, ladder placement, and tear-off sequencing before demo day so the crew isn’t improvising with a loaded truck blocking your neighbor’s driveway. Call (866) 974-2271 and we’ll assess your specific yard during the free estimate.
We price decking as an allowance per sheet in the original contract, so when we open the roof on a 1960s San Fernando home and find rotted plywood or split skip-sheathing, you already know what each replacement sheet costs. Any electrical wiring that runs through the attic is outside our roofing scope and we flag it for you to address with a licensed electrician, but we won’t bury a known problem under new shingles without telling you first. Manny walks every job personally before we open anything, so the surprises stay small and the numbers stay honest.
