CertainTeed Roof Replacement in Pasadena: What to Know First
CertainTeed roof replacement in Pasadena typically runs between $14,000 and $32,000 depending on the shingle line, roof size, and what the deck underneath needs before new material goes down. Most full replacements on a standard Pasadena home take two to four working days, and you’ll have a written price before we touch a single shingle. That number includes tear-off, deck inspection, underlayment, flashing, and clean-up – not just the shingles themselves.
This page is for Pasadena homeowners who already have CertainTeed on the roof and want straight answers about replacement: what fails, why, what it costs, and what the process actually looks like at your house. Erik Lindgren leads our crew, and he’s spent close to three decades climbing onto roofs across Pasadena and writing out exactly what he found before anyone picks up a tool. Call (626) 657-5397 and a live person answers – no phone tree, no callback wait.
How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes solid roofing products. But every shingle line has its own failure patterns, and Pasadena’s specific climate – hot sun, occasional heavy rain, and the marine layer that keeps roofs damp in the morning – brings some of those failures out faster than the manufacturer’s own marketing materials will tell you. Here’s what we actually see on Pasadena roofs:
- Landmark series granule loss at the 12-to-15 year mark. The Landmark architectural line is everywhere in Pasadena – we see it on craftsman homes in Bungalow Heaven and on mid-century ranches in Hastings Ranch. The symptom homeowners notice first isn’t a leak. It’s granules collecting in the gutters and chalky residue washing down the downspouts after rain. That granule loss exposes the asphalt coating to UV, which accelerates aging from there. When we replace a Landmark roof, we check the deck underneath carefully because granule loss often means the shingles have been shedding for years before anyone called us.
- Presidential Shake lifting at the keyways. The Presidential line replicates the look of wood shake, and the thicker profile is genuinely tough. But Pasadena’s heat cycles cause the laminated tabs to curl at the keyways over time, especially on south-facing slopes that get full afternoon sun. Once the tabs lift, wind gets underneath and works the shingles loose. On replacement, we inspect every keyway and often upgrade the nailing pattern within CertainTeed’s install specs so the new roof holds better in the same conditions.
- XT25 three-tab cracking along the nail line. Three-tab shingles like the XT25 are older-tech and thinner. In Pasadena’s temperature swings, the asphalt becomes brittle, and cracks run right along the nail line. This is a classic sign the roof is past its serviceable life – not a repairable situation. When we tear these off, we almost always find decking that needs attention too, because the brittle shingles stopped doing their job long before the cracks appeared.
- Improperly driven nails from the original install. This isn’t a CertainTeed manufacturing issue – it’s an installation issue we find constantly on Pasadena roofs from the 1990s and early 2000s. Nails driven too deep through the shingle, nails in the wrong position, or too few nails per shingle. The roof fails early because the fastening failed. When we replace, we pull back a section of the old roof first and photograph exactly what we found. You see it before we cover it up.
- Flashing failures at chimney and valley transitions on older Pasadena homes. CertainTeed’s shingles can last, but the metal around the shingles doesn’t always. On the older homes around Madison Heights and the Arroyo, we regularly find corroded step flashing and dried-out roof cement at chimney bases. Water gets in there long before the shingles themselves fail. A proper replacement means re-doing those transitions correctly – not just slapping new shingles over dying flashing.

Our CertainTeed Roof Replacement Process
Every replacement follows the same careful sequence. Nothing gets skipped, and you see the condition of your roof at each stage before we move on.
- 1
The inspection walk. We go up on the roof with a camera and document what’s actually there – the shingle condition, the flashing, the decking from inside the attic if accessible. Erik takes his time on this. You get photos and a written explanation of what we found, even if you don’t hire us.
- 2
The written price. Before any work begins, you get a dollar figure in writing. It covers tear-off, deck repair if needed, underlayment, flashing, shingles, and clean-up. No change orders unless we open the roof and find something structural no one could see from the surface – and if that happens, we stop and explain it before spending another dollar.
- 3
Protecting the house before tear-off. Shoe covers at the door, drop cloths through the hallway where we walk, tarps over landscaping and anything in the path of falling debris. If your dog needs to stay inside, we coordinate the door schedule with you so no one lets him out by accident.
- 4
Tear-off and deck inspection. Old shingles come off, and the deck gets checked carefully. In Pasadena, we find water-damaged plywood more often than you’d expect, especially on homes where the original roof was under-ventilated. We photograph any rot or damage, show you, and replace the affected sections.
- 5
Installation to CertainTeed’s specs. New underlayment, new flashing, and the CertainTeed product you chose – Landmark, Presidential, or another line – installed exactly per the manufacturer’s installation instructions. That’s what keeps their warranty intact.
- 6
Clean-up and photo proof. Every nail is magnet-swept. Debris is hauled off. And before the crew leaves, we photograph the clean-up so you can see it’s done right. That photo is part of the job, not an optional add-on.

AfterWhat CertainTeed Roof Replacement Costs in Pasadena
Replacement pricing depends on the shingle line, the roof’s size and pitch, and what the deck needs. Here’s what Pasadena homeowners should expect:
- Landmark architectural shingles: $14,000 to $22,000 for a typical 1,600 to 2,200 square foot single-story home.
- Presidential Shake: $22,000 to $32,000 for the same footprint. The product costs more, and the install is slower because of the thickness.
- XT25 or similar three-tab replacement: $12,000 to $18,000, though most homeowners step up to architectural at this point.
- Decking replacement: Adds $2 to $4 per square foot of affected area, depending on what we find.
The roof’s pitch moves the number too. A steep roof on a two-story Pasadena home means more staging, more safety equipment, and more time. And if you’re in a historic district, there may be material requirements from the city that change what you can install. Call (626) 657-5397 for an exact quote – the estimate is free, and the number you get is the number you’ll see on the written price before work starts.

CertainTeed makes good shingles. What matters on replacement day is the crew putting them on, and how they treat your house while they’re there. C.A.R.E. is how we run every job: Clean up like it’s our own home, Ask before we move or touch anything, Respect the family’s time and quiet hours, Explain the price before the work. That’s the standard, not the aspiration.
Every replacement is covered by our 365-Day Done Right Promise. If something isn’t right, we make it right – no arguing, no fine print. Our techs are background-checked and uniformed, so you know exactly who’s walking through your door.

We’ll tell you honestly what each one does well and what it doesn’t.
The name Birchbark isn’t a marketing invention. Birch bark was one of the first roofing materials – light, tough, and made to shed water. That’s the standard we build to, and the reason we keep the company small enough that Erik’s still answering the phone when you call.
FAQs
No. A full roof replacement by an independent CertainTeed service provider doesn’t void the warranty on your new shingles as long as the installation follows CertainTeed’s published installation specifications. We install to those specs exactly, and we keep documentation of materials and methods in case you ever need to file a warranty claim. Call (626) 657-5397 if you want us to walk through your current warranty status before committing to anything.
Granule loss in the gutters, curling at the keyways, cracking along nail lines, and flashing failures at chimneys or valleys are the big signals. If the decking underneath has been wet, replacement is almost always the right call, because repairs only address the surface. We’ll show you photos of everything during the inspection walk so you can make the call with real information, not a sales pitch.
Most full replacements take two to four working days. Steeper roofs, two-story homes, and decking replacement all add time.
