Why Tilehurst Roofing Is Altadena’s Preferred Roof Replacement Company

Tilehurst Roofing operates as a Kingswell family company, founded in 2000, and we built our reputation here on two things Altadena homeowners tell us they never got from the last contractor: a crew that shows up in the window it promised and a price that does not move after the first handshake. Our technicians are background-checked and uniformed, so you know who is on your roof and why. We pull LA County permits on every full replacement, and we know the fire-zone assembly submittals that make County plan check go smoothly. Many Altadena customers came to us after a repair failed within months on a pre-fire three-tab or shake roof. We put our 365-Day Done Right Promise in writing, and every repair carries a written guarantee delivered before the crew leaves, not mailed later. If something fails inside the guarantee period, we return at no charge. That is not marketing language. It is how we operate.

We answer the phone with a live person, 24/7. When you call during a Santa Ana event and embers are falling on Lake Avenue, you get a person, not a voicemail. That matters in Altadena.

Roof Replacement Contractor in Altadena

A roof replacement contractor in Altadena is not doing the same job as one working flatland Pasadena or Arcadia. Here, the contractor has to understand LA County fire-zone rules, wind exposure from San Gabriel canyon mouths, and the condition of 1920s-1950s framing that often only reveals itself once the old roof is off. A full replacement involves tearing off the existing roof to the decking, inspecting and commonly replacing damaged sheathing, installing new underlayment to fire-rated standards, then laying the shingle or tile system with correct ridge cap, drip edge, and flashing. In Altadena, most full replacements run $14,000-$32,000, with decking replacement adding $2-$4 per square foot when the old skip sheathing is cracked or termite-damaged.

Permit and Fire-Zone Requirements

Because Altadena is unincorporated, your permit comes from the LA County Department of Public Works, not a city building department. Since the Eaton Fire, the County enforces Class A assembly requirements for Very High Fire Hazard Severity Zones even on standing pre-fire homes. That means the underlayment, ridge detailing, and soffit work must be spec’d to fire code before the first shingle is ordered.

What We Check Before Quoting

We inspect the decking, the fascia, the existing flashing, and the attic ventilation during the estimate. That lets us write a real price, not a guess that changes at the door.

Asphalt Shingle Roof Replacement in Altadena

Asphalt shingle roof replacement in Altadena typically runs $11,000-$19,000 for architectural shingles on a standard single-story home, before any decking replacement. Asphalt is the most common choice for Craftsman bungalows and mid-century ranches here because it handles the UV exposure at foothill elevation well when installed with quality underlayment, and it gives you a Class A fire-rated assembly when paired with the right materials. Where older three-tab shingles strip granules and crack under intense sun and dry Santa Ana conditions, modern architectural shingles from GAF, CertainTeed, or Owens Corning hold up measurably better in the canyon wind corridors.

Architectural vs. Three-Tab in the Fire Zone

Architectural shingles are thicker, rated for higher wind uplift, and contribute to the Class A assembly rating that LA County now requires. Three-tab is still sold, but we rarely recommend it in Altadena after seeing how it granule-strips on south-facing slopes along New York Drive.

Decking and Skip Sheathing Repairs

Most pre-1960 Altadena homes have 1x skip sheathing under the old roof, not solid plywood. When we tear off, we almost always find cracked boards, gaps, and sections that need replacing to meet current nailing surface requirements. We write decking allowance into the quote so that cost is known up front.

Trusted Brands We Service in Altadena

We install and service material systems from seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Altadena specifically, we keep a strong stock of Atlas and GAF Class A fire-rated components plus Tamko architectural profiles because they match the fire-zone and wind-uplift demands we see on the Foothill corridor. If a warranty claim ever comes up, we carry the manufacturer relationships to process it directly, so you are not left calling a parts desk yourself. We do not push one house brand. We match the product to your home, your exposure, and your budget.

Common Roof Replacement Problems We See in Altadena Homes

• Wind-lifted ridge cap and flashing. The San Gabriel canyon mouths funnel Santa Ana gusts hard into the neighborhoods below Eaton Canyon and Rubio Canyon, lifting ridge cap and exposing the underlayment. Once that opening exists, ember cast from upslope vegetation has a path inside, exactly what the Eaton Fire exploited.
• Granule-stripped asphalt from foothill UV. Altadena sits at higher elevation than Pasadena, and south-facing slopes take brutal sun. Shingles lose their protective granules faster, then the asphalt matrix cracks, and water finds the mat.
• Termite-damaged ridge beams and fascia. The 1920s-1950s Craftsman and Spanish Colonial frames used old-growth lumber that termites love. We regularly find a ridge beam that looked fine from the attic but is structurally compromised once we open the ridge line.
• Permit stall from wrong-jurisdiction habits. Contractors used to Pasadena or Arcadia city permit desks often get held up on LA County Public Works plan check and fire-zone submittals. We handle County paperwork directly, so the job does not stop mid-tear-off with your roof open to the weather.
