Why Westminster Residents Choose Us for CertainTeed Service

Key Step Construction has spent years working on CertainTeed roofing and exterior systems throughout Orange County, and Westminster’s housing stock gives us a particular edge. Most of the homes here were built between 1950 and 1975, and their original roofs and siding don’t always play nicely with newer shingle and cladding products unless the contractor knows what’s underneath. We do.

Noel Garrity, our owner, grew up in Villa Park and studied construction technology at Santiago Canyon College in Orange. He built his reputation on remodels and additions that hold up quietly for decades. When we inspect a CertainTeed roof in Westminster, we’re looking at more than the shingles. We’re checking the deck, the ventilation, the flashing, and the substrate, because that’s what determines whether a CertainTeed installation lasts 15 years or 40. We’re an independent CertainTeed service provider, not a manufacturer-affiliated or authorized dealer, so our recommendations come from the field, not a corporate playbook.

Common CertainTeed Construction Problems We Solve in Westminster

Here’s what we see regularly on CertainTeed roofs and exteriors across Westminster’s ZIP codes 92683, 92684, and 92685:

• Wind uplift and granule loss on Landmark shingles during Santa Ana events. Seasonal Santa Ana winds hit exposed ranch roofs hard, especially on single-story homes with low slopes and wide eaves. When Landmark shingles lift at the edges, the seal strips break, and granules start shedding into gutters and downspouts. We see this most often on homes near open corridors where wind funnels through, including stretches around Bolsa Avenue.
• Algae staining and premature aging from coastal moisture and poor attic ventilation. Westminster’s coastal-influenced climate means cool, damp air settles into attics of 1960s ranch homes that were never built with ridge vents or soffit baffles. CertainTeed shingles hold up reasonably well, but trapped moisture accelerates granule loss and feeds algae growth that shortens roof life.
• Cracking and delamination of pre-1990s CertainTeed organic-mat shingles. Some Westminster homes still carry their original organic-mat shingles, which used a felt base that breaks down over time. Once the mat absorbs moisture, the shingles crack, cup, and eventually pull free. This is a replacement scenario, not a repair one.
• Premature seal failure on Cedar Impressions siding. CertainTeed’s Cedar Impressions polymer siding is a good product, but when installed over a substrate that shifts – common in Westminster homes with original wood siding underneath – the interlocking seams can work loose. The result is gaps that let water behind the cladding.
• Uneven shingle sealing over skip sheathing. This is the Westminster-specific one. Skip sheathing, where roof boards are spaced apart rather than laid solid, was standard building practice here through the 1960s. Modern CertainTeed shingles need a continuous nailing surface, and over spaced boards they seal unevenly, leaving edges vulnerable to wind and moisture.

CertainTeed Service in Westminster: What Local Conditions Mean for Your Roof

Westminster’s mid-century ranch homes often sit on original skip sheathing or spaced board decks. If you’re not looking for it, you won’t find it until the shingles fail. Here’s why that matters for CertainTeed work specifically: Landmark Series shingles carry a wind warranty that assumes a solid, code-compliant deck underneath. When a roofer nails CertainTeed shingles over skip sheathing without addressing it first, the shingles don’t seal in a uniform line, and a Santa Ana gust can peel an entire edge row back like a page in a book. Current building code in Westminster requires a solid underlayment or overlay before re-roofing over spaced boards. We routinely install CertainTeed RoofRunner synthetic underlayment over a new solid deck before laying Landmark Pro shingles, which is what the manufacturer’s warranty actually expects. This detail rarely comes up in neighboring cities with newer housing stock, but in Westminster it’s the norm. On a 1962 ranch home near Bolsa Avenue and Brookhurst Street, we found a Landmark shingle roof with severe wind uplift and granule loss after a Santa Ana event. The original skip sheathing caused uneven shingle sealing. We demoed down to the framing, installed a solid deck, laid CertainTeed RoofRunner over it, and finished with Landmark Pro shingles. The roof now matches both the home’s mid-century character and the wind speeds Westminster actually gets.

CertainTeed Models & Products We Service in Westminster

We install, repair, and replace the CertainTeed product lines that make sense for Westminster homes and commercial properties. That includes Landmark and Landmark Pro shingles, Presidential Shake and Presidential Shake TL, Carriage House shingles, and Cedar Impressions siding. When repairs call for replacement parts, we use CertainTeed OEM accessories and underlayments where they’re available and cost-effective, but we also source high-quality aftermarket components that meet or exceed brand specifications. That keeps repair costs reasonable for Westminster homeowners. For roofs beyond 20 years old with widespread granule loss or multiple leaks, we recommend full replacement rather than repeated patching, because the underlying deck or underlayment is usually compromised. It’s the honest call, and it saves money over time.

FAQs – CertainTeed Construction in Westminster

Do CertainTeed Landmark shingles hold up to Santa Ana winds in Westminster?

Yes, when they’re installed over a solid deck with proper nailing and sealing. Landmark shingles carry a wind warranty that covers high gusts, but the warranty assumes the roof deck meets code. In Westminster, that often means addressing skip sheathing before installation. Without that step, even warrantied shingles can lift. If you’re worried about how your Landmark roof handled the last wind event, call (855) 382-0824 and we’ll inspect it at no cost.

Can you repair my CertainTeed roof if it’s 15 years old and losing granules?

We can, but we’ll tell you if patching doesn’t make financial sense. A 15-year-old CertainTeed roof with widespread granule loss usually signals that the mat is breaking down, and adding patches to a failing surface means you’ll be back for repairs every few months. We repair localized damage when the rest of the roof is sound. If it’s not, we’ll show you why a replacement costs less over five years than repeated service calls. Call (855) 382-0824 for an honest assessment and a free estimate.

What’s the best CertainTeed roofing option for a 1950s ranch home in Westminster?

For most mid-century ranches in Westminster, we recommend Landmark or Landmark Pro shingles. They balance cost, wind performance, and appearance well on the low-slope, wide-eave profiles common to that era. Presidential Shake works if you want a heavier, more dimensional look, but it’s overkill for many ranch roofs. The right choice depends on your roof’s pitch, deck condition, and attic ventilation. We’ll walk you through the tradeoffs during a free inspection. Call (855) 382-0824 to schedule one.

Do you install CertainTeed Cedar Impressions siding on homes with original wood siding?

We do, and in Westminster that usually means removing or stabilizing the original wood first. Cedar Impressions is a polymer siding designed to mimic cedar shake, but it needs a flat, stable substrate. On a 1960s home with original shiplap or lapped wood siding that’s shifting, the interlocking seams can separate if the substrate moves. We address the underlying surface before installing, so the siding performs the way CertainTeed built it to.

How does Westminster’s coastal climate affect CertainTeed roof performance?

Westminster’s coastal-influenced climate means mild, wet winters and dry, warm summers, which is generally easier on roofing than inland heat. The bigger factor is moisture. Cool, damp air from the coast settles into poorly ventilated attics, and on 1950s and 1960s homes with minimal venting, that moisture accelerates granule loss and feeds algae growth on CertainTeed shingles. Santa Ana winds compound the problem by lifting shingle edges on exposed roofs. Both issues are manageable with proper attic ventilation and correct deck preparation.
