Fast, Reliable Roof Replacement Across Covina
Roof replacement in Covina runs anywhere from $9,800 for a simple architectural shingle tear-off on a modest ranch to $28,000 or more for a larger foothill-edge home with clay tile or a flat roof with decking replacement. Most mid-century homes in the 91722 and 91723 tracts land between $12,000 and $19,000 once decking, underlayment, and code-required upgrades are factored in. We work Covina weekly, know what these 1950s-70s roofs hide once the old layers come off, and we price every surprise in writing before moving forward. Call (866) 321-6172 to schedule a free roof replacement estimate in Covina.
Key Takeaways:
- Tear-off on a mid-century Covina tract home almost always reveals decking or underlayment issues that shingle-only bids miss.
- Rick Dominguez, who leads Van Nuys Roofing Co, insists every change is priced and approved in writing before work continues.
- We work with seven roofing manufacturers, so material choice stays in your hands, not ours.
- Free estimates with a documented tear-off inspection before you commit to a number.
Why Van Nuys Roofing Co Is Covina’s Preferred Roof Replacement Company
Covina homeowners usually call us in one of two situations: the original wood shake or composition roof is visibly failing, or a Santa Ana event peeled back ridge caps and loosened flashing. Either way, we start the same way. We inspect first, then recommend. No replacement pitch until the roof tells us what it actually needs.
Our crew has torn off enough roofs in the 91722 and 91723 tracts to know what lurks under layers installed before current code existed. That experience matters when the permit gets pulled and the building inspector wants decking, underlayment, and nailing patterns brought up to standard. We’ve handled dozens of those mid-project conversations in Covina, and we write every code-triggered change into a line-item price before we touch it.
Led by Rick Dominguez, the team runs repair, Roof Replacement, and inspection under one roof. That means nobody refers you to another contractor when a tear-off uncovers framing damage. We handle it, price it, and close it out with the inspector ourselves.
Because Covina sits close enough that our Van Nuys crews can be on-site regularly, we’re not strangers to the city’s building department, its inspection rhythms, or the specific failure patterns we see from the San Gabriel Valley’s heat and wind. You won’t get a sales pitch from us. You’ll get a straight answer about whether repair or full replacement actually makes sense for your house.
Styles & brands we work with
Flat Roof Replacement in Covina
Flat Roof Replacement in Covina is a different animal from a pitched shingle job, and it’s one we see most often on ranchers and room additions in the older tracts off Badillo and Citrus. Most Covina flat roofs are aging built-up or modified bitumen systems that have been patched once or twice already. Once the dry-rot and sun damage from decades of San Gabriel Valley heat take hold, patching becomes a losing game.
Flat roof replacement in Covina typically runs $11,000 to $22,000 depending on square footage, decking condition, and whether the roof carries mechanical equipment. The tear-off usually reveals saturated insulation board and wood decking that has to go. We price that in the line item before we open up the second half of the roof.
Built-Up and Torch-Down Systems
Most of the flat roofs we replace in Covina started as built-up asphalt systems layered under gravel. If the interior shows moisture stains near the scuppers or the membrane feels spongy underfoot, the insulation below has absorbed water and the whole assembly needs replacement. We pull the old system down to the decking, re-insulate to meet current Title 24 requirements, and install a modern multi-ply or PVC membrane based on your roof’s slope and drainage.
Code-Compliant Crickets and Drainage
Covina’s building department now requires positive drainage details on re-roofs that older flat roofs never had. That means adding tapered insulation, crickets behind parapets, and sometimes enlarging scuppers or adding new drains. These aren’t optional add-ons; they’re code triggers once the permit is issued. We include them in the contract from the start so the number you sign off on is the number you pay.

Roof Installation in Covina
Roof Installation in Covina covers both full replacement of existing roofs and installation on new additions, garage conversions, or accessory dwelling units. For replacement work, installation means a complete tear-off down to the decking, new underlayment across the entire field, proper starter strip and nailing patterns, and whatever shingle, tile, or membrane system you choose for the climate you actually live in.
A straight roof installation on a standard 1,400 square foot Covina ranch with architectural shingles runs $10,500 to $15,500. That assumes sound decking and no code-triggered framing work. When we do the tear-off and find the decking delaminated, we stop, photograph it, write the change order, and get your written approval before we order the extra plywood.
Architectural Shingles and Nailing Patterns
Covina’s Santa Ana wind exposure makes nailing patterns a safety issue, not a preference. Homes on the exposed foothill edges near 91724 need ring-shank nails at the high-wind pattern specified by the shingle manufacturer. We follow the brand’s installation spec for whatever material you pick, because manufacturer warranty eligibility depends on it. If you want CertainTeed or GAF standing up to a wind event, the nailing pattern has to match their published requirement.
New Construction and Additions
New construction roof installation in Covina usually comes up around ADU builds or second-story additions on lots zoned for it. The city reviews the roof assembly as part of the overall permit, and Title 24 energy requirements now include solar-ready zones on new residential roofs. We coordinate directly with the general contractor or handle it ourselves if the addition is a simple one. You won’t get shuffled between three crews.
Trusted Brands We Service in Covina
Van Nuys Roofing Co crews are trained on the technical installation requirements for seven major roofing lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means you choose material based on your house’s exposure, your budget, and what you actually want the roof to look like, not what the contractor happens to stock. For Covina homeowners, we keep a parts inventory that covers The common replacement profiles, and material availability for Owens Corning and GAF systems is usually same-week. Material-neutral advice is the whole point: your roof, your material choice.

AfterCommon Roof Replacement Problems We See in Covina Homes
- Rotted decking under original wood shake. The 91722 and 91723 tracts were built with shake roofs that have been cooking under San Gabriel Valley sun for 50 to 70 years. Tear-off routinely exposes decking so dry and brittle it crumbles at the nail line.
- Failed underlayment at valleys and penetrations. Heat cycling bakes felt until it powderizes. The valleys, pipe boots, and chimney flashings on Covina ranches are where we find the worst of it once the top layer of shingles comes off.
- Santa Ana wind damage on exposed ridges. Homes facing the open foothills near 91724 lose ridge caps and flashing tabs in a single strong Santa Ana event. Re-roofs that don’t upgrade to high-wind nailing patterns and starter strip fail the same way again within a few seasons.
- Framing repairs triggered by permit inspection. Once the city inspector sees the open roof, any rafters with water damage or questionable notching at penetrations have to be reinforced or sistered before we can re-sheath. We document and price these before the inspection, so you’re never surprised by the inspector’s punch list.
Pricing for Roof Replacement in Covina, CA
Replacement pricing in Covina breaks into bands. A simple architectural shingle roof on a 1,200-1,500 square foot ranch with sound decking lands between $10,500 and $15,500. Add code-required decking replacement, and you’re at $14,000 to $19,000. Clay tile or Boral stone-coated steel on a foothill-edge home with complex hips and valleys runs $22,000 to $32,000. Flat roof replacement sits at $11,000 to $22,000 depending on system type and insulation requirements.
What moves the number is what’s under the roof, not what’s on top of it. Rick Dominguez’s rule is simple: until the old roof is off and the decking is visible, any quote is an estimate, not a promise. We write that into the contract, and we price every change with photos and line items before work proceeds. Estimates are free. Call (866) 321-6172 to schedule yours.

FAQs About Roof Replacement in Covina
Because most Covina homes built in the 1950s-70s have original wood shake or early composition shingle roofs sitting on decking and underlayment that has been heat-cycling for five to seven decades. Once the top layers come off, our crews usually find delaminated plywood, powderized felt, and sometimes framing that a permit inspection requires us to reinforce. Those items cannot be known before tear-off, so our quotes include a written allowance, and any actual findings are presented as a photographed line-item change order for your written approval. That’s the only honest way to price a re-roof on a mid-century tract house. Call (866) 321-6172 if you want our team to walk your roof and show you what we’d be looking for.
Compare square and decking line items before comparing the final number. One Covina bid might price shingle installation only and stay silent on decking replacement; another might include a full re-deck line item that only gets billed if the tear-off proves it necessary. Also check whether the bid includes ice and water shield, starter strip, drip edge, and permit fees as separate lines. A low number that omits those is either dishonest or incomplete. We give you a written, broken-out quote so you can line it up against anyone else’s with clear eyes. If you’re weighing two bids, call us at (866) 321-6172 and we’ll walk you through what to look for.
Yes, Covina requires a building permit for roof replacement, and once the roof is opened, the inspector will hold you to current code for underlayment, decking attachment, ventilation, and any framing that’s compromised. On a mid-century home, that typically means at least some decking replacement and possibly Title 24 ventilation or insulation upgrades. We pull the permit ourselves, include the fee in the contract, and handle the inspection. Code triggers are priced in writing when they appear, not thrust on you after the work is done. Call (866) 321-6172 and we’ll give you a read on your specific house before you commit.
Homes on the exposed foothill edges near 91724 sit in the path of Santa Ana gusts that regularly hit 50-70 mph locally. You want a shingle rated for at least 110 mph wind uplift, installed with the manufacturer’s high-wind nailing pattern and ring-shank nails. The rating is meaningless if the nailing pattern isn’t followed, which is why our crew’s technical fluency across brands like GAF, CertainTeed, and Owens Corning actually matters for warranty eligibility. We’ll spec the right shingle class and nailing pattern for your exposure. Call (866) 321-6172 for a site-specific recommendation.
No. Flat and low-slope roofs in Covina use membrane systems like built-up asphalt, modified bitumen, or PVC/TPO, not shingles, because shingles shed water by gravity and fail on slopes under 2:12. Most Covina flat roofs started as built-up systems, and the best replacement is usually a multi-ply modified bitumen or a single-ply PVC depending on drainage, equipment loads, and sun exposure. The underlayment, insulation, and flashing details are all different, and so are the code requirements. We’ll tell you which membrane fits your actual roof, not which one we’d rather sell. For a flat roof evaluation in Covina, call (866) 321-6172.
