CertainTeed Roof Installation in Los Angeles: What to Know First

We provide independent CertainTeed roof installation in Los Angeles, typically completing standard jobs in one to two days once materials are on-site. Most full replacements on a typical 2,000-square-foot Valley or Mid-City home run $12,500 – $22,000 depending on the shingle line and how much of the underlying deck needs replacement. You’ll get a written, line-item price before we touch anything, and that number doesn’t change once work starts.

This page is for Los Angeles homeowners who already have CertainTeed shingles on their roof and need them installed correctly, whether you’re replacing an aging Landmark system or upgrading to a higher-end line after storm damage. We work with CertainTeed, GAF, and Owens Corning products daily, so we know where each brand saves you money and where it costs you if corners get cut.

How CertainTeed Products Fail – and How We Fix Them

  • Landmark shingles: premature granule loss in L.A.’s UV blast. The San Fernando Valley and inland neighborhoods like Eagle Rock and Highland Park see some of the highest ultraviolet exposure in the country. Landmark’s asphalt binder breaks down faster here than in cooler climates, and you’ll notice gutters filling with dark grit while the shingle color fades unevenly. We strip to the deck, replace any moisture-compromised plywood, and install Landmark PRO or Landmark Premium with enhanced UV stabilizers if the homeowner wants to stay in the CertainTeed family.
  • Landmark TL (Triple Laminate): delamination at the adhesive strips. The triple-layer construction is thicker and heavier, which is great for wind resistance, but the factory-applied sealant can fail in L.A.’s thermal cycling, hot days followed by cool nights. We see this especially on north-facing slopes in neighborhoods like Los Feliz where morning dew lingers. Our fix: full removal, inspect for trapped moisture, and reinstall with hand-sealing at the eaves and ridges where wind uplift is highest.
  • NorthGate SBS-modified shingles: improper fastening depth. These are rubberized for impact resistance, popular in hail-prone zones and increasingly in Los Angeles for fire-rated assemblies. But the SBS layer is softer than standard asphalt, so over-driven nails cut through and under-driven nails don’t seat flush. We use depth-calibrated pneumatic guns and spot-check every bundle with a pull tester.
  • CertainTeed starter strips: upside-down installation by prior crews. The starter shingle has a sealant band on one edge only. Flip it and the main-course shingles above it never bond properly. We’ve found this on re-roofs in Glassell Park and Atwater Village where the previous contractor rushed the job. We always run a full starter course, not trimmed three-tab, and we align the sealant band precisely at the eave edge.
  • Flashing integration with CertainTeed’s Integrity Roof System. CertainTeed sells this as a complete assembly: shingles, underlayment, ventilation, and accessories. But we’ve seen L.A. contractors substitute generic felt and skip the SwiftStart starter or Ridge Vent product, voiding the warranty. We inventory CertainTeed’s accessory line and install per the published specs, or we document exactly what equivalent product we’re using and why.

Our CertainTeed Roof Installation Process

  1. 1
    Call and schedule. A live person answers, 24/7. We book a time that works for you, not a four-hour window.
  2. 2
    On-site diagnosis. Our technician arrives at the trackable time, uniformed and background-checked. We inspect the full roof system, not just the shingles. We photograph everything and explain what we see.
  3. 3
    Written estimate with parts specified. We note the CertainTeed line, whether we’re using OEM accessories or quality equivalents, and why. The price is fixed. Every promise in writing – that’s just how we do it.
  4. 4
    Installation day. We protect your property, remove old materials to the deck, replace damaged plywood, install underlayment and flashing per CertainTeed’s specs or our documented equivalent, and lay the new shingle course with proper exposure and nail pattern.
  5. 5
    Final inspection and photo documentation. We walk the roof, check every penetration and valley, and send you before-and-after photos with your digital invoice by text.
  6. 6
    The 365-Day Done Right Promise kicks in. Any covered issue in the next year, we come back and make it right. No charge, no negotiation.

What CertainTeed Roof Installation Costs in Los Angeles

Scenario Typical Range
Landmark or Landmark PRO replacement, 1,800 – 2,200 sq ft, standard pitch, minimal deck repair $12,500 – $17,500
Landmark Premium or NorthGate, same footprint $16,000 – $22,000
Full deck replacement on 20%+ of roof area Add $3,500 – $7,000
Upgraded ventilation (ridge vent, intake baffles) Add $800 – $1,500
Complex cut-up roof: multiple valleys, dormers, steep pitch Add 15 – 25%

What moves the price: shingle line choice, how much plywood needs replacing, and how cut up your roof is. A simple gable roof in Reseda costs less than a Hollywood Hills home with four valleys and a chimney cricket. We don’t guess. We measure, photograph, and give you a written number before work starts.

Why Los Angeles Homeowners Call Crestview Roofing for CertainTeed Work

Dylan Pace grew up in Glassell Park patching flat roofs on bungalows above the LA River, and he built Crestview Roofing on the idea that homeowners deserve to know who’s coming, when they’ll arrive, and what it’ll cost. That means live trackable arrival times, before-and-after photos, and digital invoices sent by text. Our technicians are background-checked, uniformed, and trained across CertainTeed, GAF, and Owens Corning lines, so we don’t push one brand because it’s all we know. The 365-Day Done Right Promise covers every repair for a full year, including a free second visit if anything fails. We’re an independent CertainTeed service provider, not a factory-authorized program, which means we choose the right material for your roof, not the one that earns us a rebate.
