AfterFast, Reliable Roof Installation Across Glendale
A new roof in Glendale runs $14,000 to $38,000 for a typical 1,800-square-foot home, depending on material, pitch, and whether your hillside property sits inside the VHFHSZ fire zone. We complete most Glendale tear-offs and re-roofs in 2 to 5 working days once permits clear. If you’re weighing roof installation against another season of patches, call (743) 200-8347 for a written, line-item quote before you commit to anything.
Mercer Roofing knows Glendale roofs in ways a generic LA outfit can’t. We know that a Rossmoyne Spanish Colonial needs a tile-off and re-set, not a cheap shingle-over. We know Chevy Chase Canyon inspectors check Class A underlayment at final. And we know you want to know exactly who’s walking up your driveway before they ring the bell. Every Mercer technician sends their name and photo ahead of the visit, then presents a photo ID badge at the door. That’s the Roof Installation standard we’ve held since 2000.
Why Mercer Roofing Is Glendale’s Preferred Roof Installation Company
We’ve worked roofs from Kenneth Village to Adams Hill long enough to know what each neighborhood throws at a roofing crew. Verdugo Woodlands means wind-rated fastening. Rossmoyne means preserving original barrel tile while the underlayment underneath gets replaced. Northwest Glendale means tight access and older decking that sometimes needs selective lumber replacement. Our estimators write that reality into the bid instead of discovering it mid-job.
Glendale homeowners use us because the price we hand you in writing is the price on the invoice. No change orders unless you approve them in writing first. Every installation includes our 365-Day Done Right Promise: if something isn’t right within a year, we fix it. That’s a written guarantee, not a handshake. We’re part of the Threshold Group family, founded in 2000, and every independently owned location operates under the Threshold Verified standard: background-checked, identity-verified, uniformed technicians who arrive in clean marked trucks.
A live person answers our phones 24/7. When you call about your Glendale roof, you reach a human being who can schedule your free estimate. Not a voicemail tree.
TPO Roofing Installation in Glendale
TPO Roofing Installation in Glendale typically runs $9 to $14 per square foot for low-slope sections, flat roof replacements, or additions common on Glendale’s mid-century and commercial-style residential structures. TPO is a white, heat-reflective single-ply membrane that holds up well under Glendale’s intense summer sun and handles the occasional pooling that flat roofs in the flats below the Verdugos experience. It’s the right call when your roof pitch is too low for shingles or tile.
Low-Slope and Flat Roof Coverage
Homes in neighborhoods like Glenwood and Pacific-Edison often have flat roof sections over porches, garages, or sunroom additions. Those sections need a membrane like TPO, not shingles. We install fully adhered and mechanically fastened TPO systems with the same written price guarantee we give every job in Glendale.
Heat and UV Performance
Glendale summers push rooftop temperatures past 140 degrees. White TPO reflects a good portion of that heat, which keeps the roof deck cooler and can reduce cooling load on the rooms below. The seams are heat-welded, so when those Santa Ana winds kick up, there’s no adhesive strip to peel.
Shingle Roof in Glendale
Shingle Roof installation in Glendale runs $8,000 to $18,000 for most homes, with architectural shingles from GAF, CertainTeed, and Owens Corning making up the majority of our flatland and lower-hillside work. Asphalt shingles are the most common re-roof choice for Glendale’s 1950s and 60s tract homes, especially between Glenoaks Boulevard and the 134 freeway corridor. They install fast, handle the LA basin’s dry heat well, and offer a wide range of colors that work with Glendale’s mix of Spanish and mid-century architecture.
Fire-Rated Shingle Assemblies
If your Glendale home sits inside the VHFHSZ, your shingle roof has to meet Class A fire assembly standards. We install Class A shingle systems from CertainTeed and GAF with the validated underlayment that Glendale inspectors expect. The shingle itself isn’t the only thing that matters. The underlayment and assembly are what get red-tagged if they’re not compliant.
Full Tear-Off vs. Shingle-Over
Glendale building code doesn’t allow unlimited shingle-overs. If your roof already has two layers, we tear to decking and start fresh. Even with one layer, we typically recommend a full tear-off so we can inspect the decking and replace any water-damaged sheathing before it becomes a structural problem.
Trusted Brands We Service in Glendale
We install shingle systems from GAF, CertainTeed, and Owens Corning, and we’re experienced with IKO for specific architectural profiles. When you choose a brand for your Glendale roof, you get the manufacturer’s material warranty plus our 365-Day Done Right Promise on the installation. We keep common profiles and colors stocked locally for Glendale jobs, which means if a section needs repair after a Santa Ana event, we’re not waiting on a distribution run to get moving. You’ll see the exact brand and product line on your written quote before we start.
Common Roof Installation Problems We See in Glendale Homes
- Failed underlayment under intact barrel tile: In Rossmoyne, Kenneth Village, and Adams Hill, original clay and concrete tile from the 1920s – 40s often looks fine from the street. What’s underneath is not. The felt underlayment from that era breaks down after 70 to 90 years, and by the time you see a leak, water has already been working on the decking for seasons.
- Wind-lifted tile in the foothills: Chevy Chase Canyon and Verdugo Woodlands catch Santa Ana gusts that flip barrel tile that was never fastened to current wind-load specs. We see cracked and displaced tile concentrated at ridges and valleys where the wind pressure peaks.
- Non-compliant underlayment substitutions: Out-of-area crews sometimes quote a foothills roof with flatland materials. Glendale inspectors verify Class A underlayment at final and will red-tag the job. The homeowner pays for the tear-off twice. Our bids name the underlayment system upfront, and that’s what goes on the roof.
- Penetration flashing failure: On Glendale’s older Spanish Colonials, the roof-covering outlives the flashing around vents, chimneys, and skylights. We routinely replace every penetration flashing during a re-roof, whether or not the tile itself needs to come off.
Pricing for Roof Installation in Glendale, CA
A full tear-off and shingle re-roof on a 1,600 – 2,200-square-foot Glendale home runs $14,000 to $30,000. Tile-off, underlayment replacement, and tile-reset on a 1920s – 40s Spanish Colonial in Rossmoyne or Adams Hill runs $22,000 to $38,000, partly because those jobs require hand-labor on the tile and partly because VHFHSZ requirements add underlayment and fastening spec. Flat roof TPO sections run $9 to $14 per square foot. Steep hillside access, existing decking repair, and permit corrections all move the number.

FAQs About Roof Installation in Glendale
If your home is in a Glendale hillside VHFHSZ neighborhood like Chevy Chase Canyon, Verdugo Woodlands, or the Verdugo foothills, yes. Glendale building code requires a Class A fire-rated roof assembly and prohibits wood shake for any permitted re-roof in those zones. Flatland neighborhoods near the 134 don’t carry the same Class A mandate, though we install Class A-rated products throughout Glendale anyway because the performance difference is worth it. Call (743) 200-8347 and we’ll confirm your zone before you plan the job.
Because the work is different. A shingle re-roof tears off the old shingles, lays new underlayment, and nails on new shingles. A Rossmoyne barrel-tile job means numbering and removing each tile, replacing the failed felt underlayment beneath them, then hand-resetting the original tile over the new system. The labor is significantly higher. Glendale inspectors also verify the underlayment spec, so there’s no shortcut that survives final inspection.
We write an allowance into your Glendale roof contract for decking and framing repair, and we price the scope in a written change order before we touch anything beyond that. What we find under the old roof doesn’t change your price without your signature. On the 1936 Spanish Colonial in Rossmoyne we recently re-roofed, a full tile-off revealed the 80-year-old felt had failed under tile that still looked sound. We replaced the underlayment, reset the tile, replaced drip edge and fascia, added ridge venting, and passed VHFHSZ final without a correction. You’ll know before we know before we spend another dollar.
In Glendale’s VHFHSZ zones, we install Class A validated underlayment systems, typically a synthetic underlayment with ice and water shield at valleys, eaves, and penetrations. The exact product line depends on the roof assembly, but it’s named in your written quote before work starts. We don’t substitute flatland materials on a foothills roof, because we’re the ones who’d have to answer to the Glendale inspector at final.
They will test it, especially in the Verdugo foothills where gusts channel directly down the canyons. That’s why we install barrel tile and shingles to current wind-load fastening specs, with extra fastening at ridges and valleys where wind pressure peaks. Glendale’s local wind profile is one of the reasons we don’t do quick shingle-overs in the hills. If you want a roof that holds through the next Santa Ana season, call (743) 200-8347 for a free estimate.
