CertainTeed Roofing in Valley Glen, CA | Barnwood Roofing
We provide independent CertainTeed roofing service across Valley Glen, from full tear-offs to targeted shingle replacement. What makes our CertainTeed work here different is simple: we know Valley Glen’s 1950s and 60s ranch homes often carry two or three layers of old shingles and low-slope additions that fall outside CertainTeed’s steep-slope specs. That changes how we bid, how we tear off, and what we recommend. Call (855) 382-1073 for a straight answer and a free estimate.
Why Valley Glen Residents Choose Us for CertainTeed Service
Ruben Calloway started Barnwood Roofing after years working roofs across the Inland Empire, and he built the company on a principle he still repeats on estimates: “Tell me what the roof actually needs, then we’ll talk about what it costs.” That carries through every CertainTeed job we do in Valley Glen and our CertainTeed repair in Sherman Oaks. We’re not tied to CertainTeed, and we’re not a replacement-only shop. We repair, inspect, and replace across seven brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we tell you a CertainTeed Landmark roof is the right call, it’s because the math works for your home and budget, not because it’s all we stock.
Having supported CertainTeed sales & service across the region, we know these shingle lines inside out. We carry CertainTeed-branded ridge cap, starter, and underlayment where they match the shingle system, and use quality equivalents for generic flashing and vents when they outperform or speed up the job. We’ll also tell you honestly when a repair buys you a few more years versus when the shingle field is too far gone to patch. In Valley Glen, that honest read matters more than most places.

Common CertainTeed Roofing Problems We Solve in Valley Glen
- UV-baked granule loss and tab cracking on south- and west-facing slopes. Valley Glen summer heat routinely pushes past 100°F, and those slopes take it all day. CertainTeed XT 25 and older Landmark lines show this as bare patches, accelerated aging, and tabs that snap when you lift them.
- Ridge-cap and edge shingle lift after Santa Ana wind events. Valley Glen sits in a dry wind corridor, and exposed single-story ranches catch it hard. We see ridge cap peeled back and edge shingles flipped after a strong fall wind, even when the field shingles are still sound.
- Premature failure at penetrations and valleys where original flashing was reused. Decades of quick re-covers in Valley Glen mean old flashing often stayed in place. CertainTeed shingles can’t compensate for a pipe boot or valley metal that’s been there since Eisenhower was president.
- Nail popping and deck movement on third-layer overlays. Many Valley Glen homes have original or second- and third-layer shingle stacks over 1×6 skip sheathing. CertainTeed shingles nailed over this will telegraph every seam, pop nails, and fail early.
- Flat-roof or low-slope addition leaks running under the shingle field. This is the one we see weekly. A mid-century Valley Glen addition with a low-slope or flat roof gets shingled anyway, and the leak shows up where the low slope meets the pitched section. CertainTeed’s shingles aren’t rated for that condition.
CertainTeed Service in Valley Glen: What Local Conditions Mean for Your Equipment
Here’s the detail that shapes every CertainTeed bid we write in Valley Glen, and it’s one a generic roofing page won’t give you. The 1950s-60s tracts that make up most of this ZIP were built with low-slope and flat-roofed additions and carports, and those low-slope sections often fall outside CertainTeed’s steep-slope shingle warranty and installation specs. A proper Valley Glen bid separates the pitched field from the flat runs instead of running shingles straight down over both. Around Grant High and the ranch-home blocks nearby, we routinely tear off two or three layers and find the low-slope section was never flashed correctly in the first place. If you’re getting CertainTeed quotes, ask each contractor how they’re handling the flat addition. If they don’t have an answer, keep calling.
CertainTeed Models & Products We Service in Valley Glen
We service and install the full CertainTeed residential lineup: Landmark architectural shingles, Presidential Shake for heavier dimensional profiles, XT 25 three-tab for older homes where a match matters, and Symphony for homeowner-grade architectural coverage. When we replace a CertainTeed roof in Valley Glen, we use CertainTeed-branded starter, ridge cap, and underlayment where they form part of the rated system. For flashing, vents, and other generic components, we’ll use quality equivalents when they hold up better or get the job done faster. And if the deck under your three-layer tear-off is rotted or spaced too wide, we’ll re-deck before a single shingle goes down. No exception.

AfterCertainTeed Service Pricing in Valley Glen
North Hills CertainTeed service and Valley Glen work ranges based on scope, but a few bench marks help. A straightforward shingle replacement on a small section runs $350 to $900. A full tear-off and reroof with Landmark architectural shingles on a typical Valley Glen ranch runs roughly $14,000 to $22,000, depending on layers being removed, deck condition, and flat-section scope. Re-decking over damaged skip sheathing adds $3 to $6 per square foot but is often the difference between a roof that lasts five years and one that lasts thirty. Our free estimate includes a roof inspection, a written line-item quote, and a straight recommendation on repair versus replacement. Call (855) 382-1073 and we’ll walk the roof with you.

FAQs – CertainTeed Roofing in Valley Glen
No, not legally, and not smartly. California building code caps re-covers at two layers, and most Valley Glen homes are already at or past that. Adding CertainTeed Landmark over three existing layers would also put more weight on framing and skip sheathing that was never intended for it. Tear-off, deck inspection, and re-nail are the real scope here. Call (855) 382-1073 and we’ll confirm what’s on your roof before you commit to a bid.
Look at the slope. Sun failure shows up as granule loss and cracking on the south- and west-facing roofs, the ones that bake all afternoon in Valley Glen heat. Wind failure shows up as lifted tabs, peeled ridge cap, and missing shingles along exposed edges after Santa Ana events. We’ll inspect both and tell you whether targeted replacement makes sense or whether the whole field is too far gone. Free estimates, no obligation.
Usually yes. Presidential Shake is a heavier, premium dimensional shingle designed for steep-slope looks and higher wind ratings. On a low-pitch 1950s ranch, the visual mismatch and cost don’t pencil out for most homeowners. CertainTeed Landmark or Landmark Pro delivers better value on these homes. We’ll show you samples against your actual roofline so you can decide with your eyes open.
No. CertainTeed shingles require a minimum slope, and most Valley Glen additions and carports fall below it. The fix for a flat or low-slope section is modified bitumen or a similar flat-roof system, properly flashed where it meets the shingle field. We handle both under one roof, so you’re not juggling a shingle contractor and a flat-roof contractor. Call (855) 382-1073 and we’ll assess the whole envelope.
You’re looking at tear-off, deck replacement or re-sheathing, re-nailing, underlayment, and new CertainTeed shingles, plus any venting fixes the home has needed for years. On a ranch home near Grant High, we tore off three layers of CertainTeed XT 25 and found the original 1×6 skip sheathing too weathered to re-nail. We re-decked the whole house before laying Landmark architectural shingles. The homeowner had been quoted an overlay by another roofer. The deck inspection changed everything. Expect deck work to run $3 to $6 per square foot on top of the reroof, and plan for it when the layers stack up. Call (855) 382-1073 for an exact quote, free.
