Why Van Nuys Roofing Co Is Valley Glen’s Preferred Roof Replacement Company
We’ve worked on enough Valley Glen roofs to know what’s under them before we even set up the ladder. The single-story ranches and traditional tracts in this part of the San Fernando Valley hide a specific set of problems: original wood shake that’s been re-covered instead of torn off, dry-rotted sheathing from decades of extreme heat, and stucco-to-roof transitions that leak at the first concentrated winter storm. We’re not guessing when we walk a Valley Glen roof. We’re looking for what we already know is there.
Rick Dominguez built Van Nuys Roofing Co around a simple rule: inspect first, recommend second. That’s why we offer standalone roof inspections in Valley Glen with no repair purchase required. If your roof has another few years in it, we’ll tell you that. If it’s done, we’ll show you the photos and explain exactly why.
Our team is fluent in the installation specs for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven leading brands, one crew that knows them all. That means the product recommendation you get is based on what your Valley Glen roof actually needs, not on what we happen to stock or what a supplier is pushing this quarter.

Roof Installation in Valley Glen
Roof Installation in Valley Glen means tearing everything down to the deck, repairing or replacing what’s failed, and building back a roof that handles both the 100°F-plus summers and the rare but intense winter rains this flat basin gets. For a typical Valley Glen ranch, a full architectural shingle installation lands between $11,000 and $18,000 before any decking contingency is applied. The wildcard is what’s under the old roof, and in Valley Glen, there’s almost always something.
What a Proper Tear-Off Looks Like Here
On a low-pitch hip-and-gable ranch off the Valley Glen tract streets near ZIP 91404, our crew tore off three layers of failing shake over the original 1x sheathing and found roughly a third of the decking soft and delaminated from decades of attic heat. We re-decked those runs, laid ice and water shield through the valleys, set new drip edge and starter strip, and nailed GAF architectural shingles to the 130 mph pattern the wind rating actually depends on, then documented the decking replacement with photos for the homeowner’s insurer. That’s what a compliant Valley Glen roof installation looks like: every layer addressed, and a paper trail to prove it.
Decking Contingency Is Standard Here
Any Valley Glen quote that doesn’t include a decking contingency line item is a quote we’d read twice. Original 1950s wood shake routinely hides dry-rotted or delaminated sheathing after decades of Valley heat. A flat bid that doesn’t account for replacement decking either hasn’t looked at this neighborhood closely or is planning to bill you for it later.
Roof Replacement Contractor in Valley Glen
Choosing a Roof Replacement Contractor in Valley Glen comes down to one question: does the installer understand what this specific housing stock needs? Because these aren’t new-build homes. They’re 70-year-old tract ranches, often still carrying original or early asphalt shingles over original decking. We plan for what’s under the surface. A full replacement with architectural shingles on a standard Valley Glen ranch typically runs $11,000 – $18,000, plus decking work if the tear-off reveals rot.
Wind Rating and Nailing Pattern
Architectural shingles are commonly sold as “130 mph rated,” but that rating only holds if the shingles are installed to the manufacturer’s specified nailing pattern. Hand-nailing outside that pattern means the rating never actually attaches to your roof. We nail to spec and document it. This matters in Valley Glen, where dry Santa Ana winds add real wind-lift risk to every roof.
Flashing and Wall Transitions
Stucco-to-roof flashing and penetrations get patched far too often in Valley Glen rather than rebuilt. The first concentrated winter storm sends water behind the stucco at wall transitions. We replace flashing, don’t paint over it. We rebuild the transition, don’t caulk around it.
Trusted Brands We Service in Valley Glen
We’re certified or deeply experienced with seven of the industry’s leading roofing material brands: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral.

Your roof, your material choice. Manufacturer warranty eligibility is available across multiple brands, so you’re never locked into one ecosystem just to get a decent warranty.

AfterCommon Roof Replacement Problems We See in Valley Glen Homes
- Re-covered original wood shake. Many of these 1940s – 1960s tract homes still have the original shake buried under two or three layers of later asphalt. The shake traps heat and moisture, and when it’s finally torn off, the decking underneath is often soft or delaminated.
- Dry-rotted sheathing from extreme Valley heat. Summers routinely exceed 100°F in Valley Glen, cooking attic spaces and drying out wood decking over decades. A tear-off here reveals bad sheathing far more often than in cooler or newer neighborhoods.
- Failed stucco-to-roof flashing at wall transitions. The flat San Fernando Valley basin gets concentrated winter storm systems that expose weak flashing fast. When water gets behind stucco at a roof-to-wall transition, the damage often spreads before the homeowner sees any interior stain.
- Aged asphalt shingles that look fine but aren’t. The heat accelerates shingle aging even when the surface looks intact. Granule loss, curling edges, and brittle underlayments are routine on Valley Glen roofs approaching 20 years old.
Pricing for Roof Replacement in Valley Glen, CA
A straightforward architectural shingle replacement on a typical Valley Glen ranch runs $11,000 – $18,000. Flat roofing, if your home has a low-slope section, adds $9 – $15 per square foot depending on the system. Roof decking replacement, when tear-off reveals rot, adds $2 – $4 per square foot. New construction or full roof installation on a larger Valley Glen property starts around $18,000 and scales with roof complexity. The variables are decking condition, roof pitch, number of penetrations, and whether we’re removing one layer or three. We give written line-item quotes before any work starts.

FAQs About Roof Replacement in Valley Glen
Yes. Valley Glen sits in a wind zone where installed asphalt shingles generally need to meet a 130 mph wind rating, and that rating only counts if the shingles are nailed to the manufacturer’s specified pattern. A shingle sold as “130 mph rated” but hand-nailed outside the pattern is not actually a 130 mph roof. We nail to spec, document the pattern, and include that documentation with your project file.
Because original 1950s wood shake traps heat and moisture against the sheathing for decades, and Valley Glen summers routinely exceed 100°F. That combination dries out and delaminates the wood decking even when the shingles above still look passable. When we tear off the old layers, we routinely find a third or more of the decking needs replacement. This is so predictable in Valley Glen that we build a decking contingency into nearly every quote.
A compliant quote includes tear-off of all existing layers, a priced decking contingency, ice and water shield through valleys and at eaves, rebuilt flashing at stucco-to-roof transitions, documented nailing patterns for the wind rating, and permit and inspection line items. A cheap bid leaves out the decking contingency, patches existing flashing, skips the permit, and either omits or ignores the wind-rating documentation. That’s the gap between a roof that holds up in a storm and one that leaks behind the stucco. Call (866) 321-6172 and we’ll show you the difference line by line.
Put the bids side by side and check for the same line items: tear-off depth, decking replacement allowance, underlayment type, ice and water shield placement, flashing scope, ventilation, nailing pattern documentation, permit handling, and warranty registration. If one bid is $3,000 cheaper, figure out which of these line items is missing. Usually it’s the decking allowance or the flashing work. We’re happy to review a competing Valley Glen quote with you and point out what’s covered and what isn’t. No charge for the conversation.
It can, and it’s the strongest reason to demand documentation. When a Valley Glen homeowner files a storm damage claim, the insurer asks whether the roof was installed to current code and whether the installation is documented. Photos of the decking repair, the nailing pattern, the flashing work, and a passed permit inspection can be the difference between a paid claim and a denied one. We photograph every layer because the documentation is part of the roof now, not an afterthought. Call (866) 321-6172 to schedule a free estimate, and we’ll explain exactly what we document and why.
