Fast, Reliable Roof Replacement Across San Fernando
Roof replacement in San Fernando typically runs $8,500 to $16,500 for an asphalt shingle roof on a standard 1,200 to 1,800 square-foot post-war stucco home, with Spanish tile replacement landing between $18,000 and $35,000 depending on whether the underlayment and decking need full removal. Most jobs take four to seven working days once materials are on site. We’ve worked the 91340 grid long enough to know which houses were built in the 1950s boom and which got infill additions in the 1990s, and that changes how we price and sequence the work. Call (833) 589-7850 for a straight answer before you spend anything.
Why Bedrock Roof Repair Is San Fernando’s Preferred Roof Replacement Company
Bedrock Roof Repair works with seven major roofing brands: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in San Fernando because the right material for a low-pitch 1950s rancher near San Fernando Road isn’t the same as what suits a newer stucco two-story off Maclay Avenue. We don’t steer you toward one manufacturer’s line because we’re not tied to one. Alan Cofield built the company around a repair-first sequence: inspect, then repair what’s fixable, and replace only when the roof actually needs it. The name isn’t a marketing line. It’s the order of operations.
San Fernando homeowners tend to be skeptical of contractors who show up and immediately recommend a full replacement. That skepticism is healthy. We’ll tell you what your roof actually needs: repair, replacement, or nothing yet. When replacement is the honest answer, we write the scope in plain language and give you a line-item quote before any work starts. You’ll know where every dollar goes, and you’ll approve any change in writing before we spend it.
Styles & brands we work with






Flat Roof Replacement in San Fernando
Flat Roof Replacement in San Fernando is a different job than a pitched shingle tear-off, and it shows up most often on the mid-century single-story homes and rear additions that pepper the 91340 ZIP. We see a lot of original built-up roofing and older modified bitumen that has baked through decades of Valley floor heat, cracked at the seams, and started letting water pool against parapet walls and scuppers. A flat roof replacement here runs $9 to $14 per square foot for a full tear-off and new membrane, putting most San Fernando flat roofs between $7,000 and $15,000 depending on size, access, and whether the underlying decking needs repair.
What the job actually involves
We strip the old membrane down to the deck, check the sheathing for heat rot and sag, then install new tapered insulation where needed to fix ponding, followed by a GAF or CertainTeed membrane system with proper flashing at penetrations and edges. On San Fernando flat roofs, drainage is the thing that separates a 20-year roof from one that fails in five. We rework scuppers and add crickets where the original builder skipped them.
When San Fernando homeowners should replace instead of patch
If you’re seeing bubbles in the roof surface, persistent leaks around vents or HVAC curbs, or standing water that’s still there 48 hours after a winter storm, patching has probably run its course. Heat-driven membrane shrinkage and cracked seams are structural, not cosmetic. We’ll inspect the roof and tell you honestly whether a targeted repair buys you more years or whether the replacement clock ran out.
Roof Installation in San Fernando
Roof Installation in San Fernando covers both new construction on the city’s infill lots along redeveloped corridors and full re-roofs where the existing system is beyond repair. For new construction, the work is sequenced with the framing crew: decking, underlayment, flashing, then the finish material. A new asphalt shingle roof on a new build or full re-roof runs $5.50 to $8 per square foot, which puts most San Fernando installations between $9,000 and $18,000. Tile installations run higher because of the material weight and the underlayment system the San Fernando climate demands.
New construction sequencing
On a new build in the 91340 grid, we work around the framing schedule and city inspections, pulling the re-roof permit when required and installing to current Title 24 energy standards. That means the right underlayment for a hot-climate roof, not the cheapest roll of felt that meets minimum code. The difference shows up in year eight, when a properly installed system still looks flat and tight while a corners-cut job starts telegraphing seams.
Decking replacement on older San Fernando homes
When we open up a roof on a 1950s San Fernando stucco home, we expect to find 1×6 skip sheathing, not plywood. That’s period-correct construction, but decades of thermal cycling dry it out, and the gaps between boards don’t support modern shingle fastening the way a solid deck does. We quote decking replacement as an allowance line in the contract: so much per sheet, used only if we find rot or unsound wood. You approve the actual quantity in writing before we order more material. No surprises, because the surprise was already priced.
Trusted Brands We Service in San Fernando
We install and service roofing systems from CertainTeed, Owens Corning, IKO, and Atlas, plus the other major brands in our lineup. That means a San Fernando homeowner choosing an architectural shingle in a heat-reflective colorway isn’t locked into a single manufacturer’s price book. We stock common flashing, underlayment, and fasteners for San Fernando jobs locally through our Anaheim yard, which keeps material lead times short when a tear-off reveals decking damage mid-job. Same team from inspection to final nail: no handoffs, no surprises.

AfterCommon Roof Replacement Problems We See in San Fernando Homes
- Heat-brittle shingles on south and west slopes. San Fernando’s summer sun pushes roof surface temperatures past 160°F on a 100°F day. Original 1950s asphalt shingles on those slopes lose granules, crack at the edges, and expose the felt underneath to UV. The roof looks tired but “intact” until the first real winter rain finds every weak seam.
- Failed underlayment hiding under Spanish tile. The clay tiles on a 91340 tile roof can look perfectly fine from the curb while the felt beneath has baked into brittle sheets that crack at penetrations, valleys, and eaves. Water gets through during winter storms and runs along the decking until it finds a path into the ceiling. Replacing just the broken tiles fixes nothing.
- Low-pitch shingle roofs with inadequate eaves protection. Many post-war tract homes in 91340 were built with shallow roof slopes and minimal ice and water shield at the eaves and valleys. Wind-driven winter rain backs up at the edge, rots the fascia, and creeps under the starter course. When we replace these roofs, we extend the underlayment further up the slope than the original builder ever did.
- Undersized rafters and dry-rotted skip sheathing. On 1950s construction near San Fernando Road and throughout the older grid, 2×4 rafters spaced wider than modern code allows, paired with 1×6 skip sheathing, were standard. Thermal cycling dries the sheathing, rafters sag over long spans, and the roof surface develops a visible wave. A replacement that doesn’t address the structure under the shingles will fail early.
Pricing for Roof Replacement in San Fernando, CA
A typical asphalt shingle replacement in San Fernando runs $8,500 to $16,500. Architectural shingles add $1 to $2 per square foot over three-tab. Tile roofs run $18,000 to $35,000 because of the tear-off weight, the new underlayment system, and the labor to reset or replace tile. Flat roofs land between $7,000 and $15,000. Decking replacement, when needed, is $2.50 to $4 per square foot for new plywood or OSB, quoted as an allowance so the final number only moves if we show you rotted wood and you approve the fix.

FAQs About Roof Replacement in San Fernando
Because the tiles are not the waterproofing layer. The underlayment beneath them is what keeps water out, and a 1950s tile roof in 91340 has underlayment that has baked through 70 San Fernando summers until it cracks at every penetration, valley, and eave. The tiles sit on top looking unchanged while water slips through the cracked felt and runs across the decking. The fix is a full underlayment replacement with the tile reset or replaced, not a spot repair. Call (833) 589-7850 and we’ll inspect the roof and show you exactly what’s happening under the tile before you spend a dollar.
Dry-rotted 1×6 skip sheathing, sagging 2×4 rafters, undersized or non-existent eave flashing, and original felt that crumbles when you touch it. We recently tore off a failed tile roof on a 1950s stucco home near San Fernando Road and found all of it: rotted decking, rafters that had deflected over long spans, and valleys with no ice and water shield. Our crew replaced the rotted sheets, sistered the rafters, installed new underlayment, set Boral clay tile with new flashing and drip edge, and every surprise was priced and approved in writing before we ordered materials. That’s how we handle every San Fernando replacement.
Permit fees and inspection costs run $300 to $800 on most San Fernando roof replacements, depending on the scope and the city’s current fee schedule. We pull the permit, schedule the inspections, and make sure the job passes the first time. If the inspector requires an upgrade because the roof structure doesn’t meet current code, that cost gets priced and approved before we proceed, not after the fact. Call (833) 589-7850 and we’ll walk you through what applies to your specific address.
For most San Fernando homes, an architectural asphalt shingle in a lighter, heat-reflective color is the best balance of cost, weight, and UV resistance. For tile roofs, the answer is new synthetic underlayment under the existing or new tile, not a cheap felt replacement. For flat roofs, a single-ply membrane with proper insulation taper to fix ponding. The honest answer depends on your roof’s slope, orientation, and structure. We’ll tell you what your roof actually needs after we look at it. Estimates are free.
Ask for a line-item scope written to the same square footage, decking allowance, underlayment spec, and finish material. A cheaper quote that omits decking replacement or uses thinner underlayment isn’t cheaper; it’s just less roof. We quote San Fernando jobs by actual roof surface, measured on site, with allowances written into the contract and every line explained in plain language. If another quote doesn’t show you the same breakdown, make them. Then call (833) 589-7850 and compare ours.
If your roof has been baking in San Fernando heat since before the 5 Freeway widened, and you’re tired of patching leaks that come back every winter, call (833) 589-7850 and we’ll inspect it honestly. Repair when possible. Replace when necessary. Inspect before either. Bedrock Roof Repair serves all of San Fernando, 91340 and 91341, with a free estimate and a written scope before any work begins.
