Fast, Reliable Roof Replacement Across San Fernando
Roof replacement in San Fernando costs between $14,000 and $28,000 for a typical 1,200 to 1,800-square-foot mid-century ranch, with architectural shingle systems landing in the $18,000 to $24,000 range most often. The price you’ll actually pay depends heavily on one thing most roofers won’t mention until after they’ve pulled the old shingles off: whether your 1950s or 1960s home still has the original skip sheathing underneath. If it does, city code requires solid decking before any new roof goes on, and that’s a cost and a separate inspection step you need to know about before you sign anything.
At Crestview Roofing Co Santa Clarita, we’ve walked San Fernando homeowners through this exact situation dozens of times. We know the neighborhoods off Maclay Avenue and San Fernando Road, we know how the city’s permit desk processes roof submittals, and we give you a written price before any work starts. Call (661) 219-7793 for a free estimate and a straight answer about what your roof actually needs.
Why Crestview Roofing Co Santa Clarita Is San Fernando’s Preferred Roof Replacement Company
Our Roof Replacement team has worked on the stucco ranch homes that define San Fernando since our founding in 2000, so we’ve seen nearly every roofline configuration these post-war neighborhoods throw at us. Low-slope hip roofs over three-bedroom floor plans, original wood shake that’s baked brittle under the Valley sun, skip sheathing that predates modern building codes. None of it surprises us anymore, and none of it gets handled with a phone quote and a handshake. Our crews are background-checked and uniformed, and you’ll get a live arrival time you can track the same way you’d track a rideshare.
We don’t ask San Fernando homeowners to take our word for it on a handshake. Every job is bound by The Relay Visibility Guarantee: a written price before work starts, before-and-after photo documentation, a live trackable arrival time, and a digital invoice sent by text. If a repair we make during a replacement fails within 365 days, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, in writing, on every job, included at no extra cost.

Reroofing in San Fernando
Reroofing in San Fernando means tearing off the old roofing material down to the deck and installing a completely new system, and on homes built between 1950 and 1975, it almost always means addressing the original skip sheathing first. The housing stock here is largely mid-century single-story stucco ranch homes, often with low-slope or hip roofs, originally built with wood shake or composition shingles. Those materials have outlived their useful life by fifteen or twenty years in many cases, and the hot, dry summers have done real damage to the shingle granules and the underlayment beneath them.
What a Tear-Off Actually Involves Here
We strip every layer of old shingles down to the deck. On most 1950s and 1960s San Fernando homes, that deck is skip sheathing – 1×6 boards spaced apart rather than a solid sheet. Current code requires solid decking before re-roofing, so we install 1/2-inch CDX plywood over the spaced boards, then synthetic underlayment, new drip edge, flashing at all penetrations, and the shingle system itself.
The Inspection Step Most Homeowners Miss
The city requires a mid-roof inspection once the solid decking is on but before shingles go down. That means the job has to be sequenced in two phases. We tarp and schedule the plywood inspection, then lay shingles only after the inspector signs off. A roofer who doesn’t pull this permit and schedule this inspection leaves you with a roof that can’t pass a future resale inspection. We handle the permit, the submittal, the scheduling, and the inspection for you.
Flat Roof Replacement in San Fernando
Flat roof replacement in San Fernando typically runs $11,000 to $22,000 depending on the square footage and the system you choose. Many of the homes in the older tracts near San Fernando Road and around Brand Boulevard have flat or near-flat sections over carports, additions, or utility rooms, and those sections degrade faster than pitched roof areas because water has nowhere to drain off quickly. The Valley’s UV exposure breaks down older built-up asphalt roofs and torch-down membranes within fifteen to twenty years, even when the pitched sections of the same home are still intact.
Why Flat Sections Fail First Here
Flat roofs hold heat longer than pitched roofs, and that thermal cycling shortens the life of the membrane. Once the surface begins to alligator-crack under the San Fernando sun, water finds its way to the seams and flashings. By the time a homeowner sees a stain on the ceiling, the underlying insulation is often saturated and the repair has become a replacement.
Systems We Install
We install modified bitumen systems and single-ply membranes with manufacturer-backed materials, and we document every stage with photos so you know exactly what was beneath the new surface before it was sealed up. Thermal imaging and moisture checks are part of the pre-work inspection on flat sections. If the underlying decking is compromised, we address that before any new membrane goes on.
Trusted Brands We Service in San Fernando
We install and repair roofing systems using manufacturer-backed materials from GAF, CertainTeed, and Owens Corning. We stock common components for these systems locally so San Fernando customers aren’t waiting on a distributor order for every replacement. For the post-war ranch homes we see most often, we typically recommend a CertainTeed architectural shingle for its heat resistance and the depth of its manufacturer warranty, but we’ll show you samples from multiple lines and walk you through the cost difference in writing before you choose.

AfterCommon Roof Replacement Problems We See in San Fernando Homes
- Original skip sheathing under layered composition shingles. The older Mission Hills-adjacent tracts off San Fernando Road were built with 1×6 boards spaced apart, not solid decking. Current city code requires solid decking before any reroof, which adds material cost and a separate inspection step that a roofer who never pulled the permit will skip completely.
- Architectural review rejections on the color and material submittal. The city’s permit desk can send a submittal back if the color and material sample doesn’t match the neighborhood’s approved palette, and that resets a 2-to-4-week review clock. We submit the samples with the packet the first time so the review doesn’t stall.
- Ridge vents installed without soffit intake. A ridge vent added without balancing intake at the soffits turns the attic into a negative-pressure zone, which keeps heat trapped and shortens shingle life in San Fernando’s summer heat. We check the full attic ventilation system before recommending any vent changes.
- Two-plus layers of old shingles hiding decking damage. Many 1960s homes here have had shingles nailed over the original roof once or twice already, which traps heat and moisture against the decking. We strip to the deck on every tear-off, no exceptions, so the new system is built on something that will actually last.
Pricing for Roof Replacement in San Fernando, CA
A full tear-off and replacement on a standard 1,400-square-foot San Fernando ranch home with architectural shingles, solid decking replacement over skip sheathing, new underlayment, new drip edge, and ridge vent runs $18,000 to $24,000. A flat roof section added to that same job runs $4,000 to $9,000 depending on square footage and the membrane system.

FAQs About Roof Replacement in San Fernando
The city’s review typically runs 2 to 4 weeks for a complete submittal, and you can cut that the most by including the material and color samples the neighborhood’s approved palette requires in the first packet. A missing sample means a rejection and a reset of the review clock. We assemble and file the full submittal for you, including the architectural review components, so the permit isn’t stuck on a desk for the wrong reason. Call (661) 219-7793 and we’ll walk you through the current timeline.
Yes. We pull the city permit, prepare the submittal packet with the required material and color samples, schedule the inspections, and we’ll work with your HOA on whatever documentation they need for the architectural review. That’s standard practice for us, not an upsell. The mid-roof inspection happens after we install solid decking and before we lay shingles, and we coordinate that so your home isn’t left exposed for longer than necessary.
No, not per current code. The city requires solid decking before a re-roof, which means the original 1×6 boards spread with gaps have to be covered with plywood before any new shingles go on. That’s not a corner we’ll cut to make a quote look cheaper. We include the decking in the written estimate up front, and we schedule the plywood inspection before shingle installation begins.
New solid decking over original skip sheathing, synthetic underlayment, new drip edge, replacement flashing at all chimneys and vents, and a balanced ventilation system that includes intake at the soffits if a ridge vent is installed. We also document the entire job with before-and-after photos and send a digital invoice by text when the work is done. Call (661) 219-7793 for a written quote that shows each of those line items.
We sequence the job around the inspection. We strip the old roof, install the solid decking, tarp the exposed sections, and schedule the mid-roof inspection as fast as the city can get there. Only after the inspector signs off do we lay underlayment and shingles. You never have to call the city yourself, and your home isn’t left open to rain for any longer than the inspection calendar requires. Call (661) 219-7793 and we’ll explain the sequence for your specific roof.
