Fast, Reliable Roofing Company Across Van Nuys
Roof work in Van Nuys comes with a specific set of demands that most roofing companies don’t prepare for. The San Fernando Valley sun bakes composition shingles until they crack, and the low-slope sections on post-WWII ranch homes pond water after every winter rain. A roof here has to handle both extremes, and the permit process has its own rules too. Mercer Roofing Co Woodland Hills sends background-checked, photo-badged technicians to Van Nuys who know exactly what those rules are. If you’re wondering what a roof repair or full replacement should cost in this neighborhood, we give you a written price before any work starts. Call (341) 217-2677 to schedule a free estimate and we’ll walk you through what your specific roof actually needs.
Why Mercer Roofing Co Woodland Hills Is Van Nuys’s Preferred Roofing Company
Van Nuys homeowners have a particular worry when they schedule roof work: who is actually showing up at the door. We solved that before we ever set foot in the Valley. Every Mercer technician sends their name and photo to you before the visit, arrives in a clean marked uniform, and presents a photo ID badge at the door. That’s the Threshold Verified standard, and it’s contractually required of every independently owned location in the Threshold Group family, founded in 2000. No surprises at the door, no wondering who’s on your property.
Our Roofing Company team handles repairs through full tear-offs across Van Nuys, from the 1950s ranch homes in Valley Glen to the traditional-style houses near Sepulveda Basin. We’ve pulled permits with LADBS for wind uplift requirements on the 91405 side of the neighborhood more times than we can count, and we know which inspectors want to see the nailing pattern documented before they’ll sign off. That local familiarity means fewer callbacks and a smoother inspection day for you.
Grant Whitlock leads our team with one standing rule: every repair gets a written guarantee, and if it fails within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every job. Van Nuys residents also get a live person on the phone 24/7, not a voicemail tree. When a Santa Ana wind tears flashing loose at 9 p.m., you call and a human answers.
Styles & brands we work with
Residential Roofing in Van Nuys
Residential Roofing in Van Nuys usually means one of two situations: a single-story ranch with a low-slope section that’s been patched too many times, or a mid-century traditional home whose composition shingles have given up after decades of Valley heat. A full replacement on a typical 1,200 to 1,600 square foot Van Nuys ranch runs $9,500 to $14,800 including tear-off, underlayment, and architectural shingles. A partial repair on damaged flashing or a small leak area typically runs $450 to $1,100.
The permit is where a lot of quotes get fuzzy. LADBS requires a re-roof permit for any roof in Van Nuys, and the plan has to show compliance with wind uplift standards for the San Fernando Valley wind zone. That means the nailing pattern, underlayment type, and edge flashing details all need to be specified. A cheap bid that skips the permit saves you $600 to $900 on paper, but it voids the manufacturer’s wind warranty and can become a problem if you ever file an insurance claim after a storm. We pull the permit, document every step, and walk the inspection with you.
Full Tear-Offs for Older Ranch Homes
Many Van Nuys ranch homes from the 1940s – 1960s have original wood shake or tar-and-gravel roofs that no longer meet fire code. A tear-off on these homes includes new decking where the plywood has rotted, a full underlayment layer, and shingles rated for the wind zone. Expect $11,000 to $16,500 for a ranch under 1,800 square feet, depending on decking replacement and how many low-slope sections need a membrane system instead of shingles.
Re-Roofs With Wind Uplift Documentation
When we re-roof a Van Nuys home, the quote includes the specific high-wind nailing pattern required by the 2023 California Building Code for this valley wind zone. That’s six nails per shingle in most cases, not the four-nail pattern a cheaper crew might default to. We note it on the permit application and the inspector verifies it. The documentation matters later if a wind event damages the roof and you need to show the insurance adjuster the install met code.
Roof Maintenance in Van Nuys
Roof Maintenance in Van Nuys is less about fixing what’s broken and more about slowing down what the sun and ponding water are doing to your roof. A maintenance visit typically runs $250 to $475 and includes clearing debris from valleys and scuppers, checking flashing around penetrations, sealing minor cracks, and inspecting the low-slope sections for standing water. We recommend it every 12 to 18 months for most Van Nuys homes, and more often if you have large trees overhanging the roof near the Sepulveda Basin area.
Low-slope sections need specific attention here. Tar-and-gravel roofs from the 1950s crack under UV exposure, and once water sits in those cracks, the decking underneath starts to rot. We apply elastomeric coatings on low-slope areas to reflect heat and bridge small cracks before they open up. A coating application for a typical ranch’s low-slope section runs $1,800 to $3,200, and it can add five to seven years of life to an otherwise sound base.
Drainage and Scupper Clearing
Ponding near scuppers is the most common issue we see on Van Nuys ranch homes. When the drain path is clogged with leaves and Valley dust, water backs up and sits for days after a rain. We clear the scuppers, check the slope, and recommend whether a tapered insulation or additional drain is needed. It’s a small cost, usually $150 to $350, compared to a $3,000+ decking replacement from rot.
Seasonal Inspection After Santa Ana Winds
After a strong Santa Ana event, it’s worth having someone check the roof even if you don’t see a leak. Shingles can lift without tearing off completely, and the next rain finds the gap. A post-wind inspection runs $200 to $300 and takes about an hour. We document what we find with photos, so you have a record if you need to file a claim.
Trusted Brands We Service in Van Nuys
We install and repair shingle systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko, and we stock common parts locally so Van Nuys customers aren’t waiting on a distribution run for a bundle of shingles. GAF Timberline HDZ is the most requested architectural shingle for Van Nuys ranch homes because it carries a 110 mph wind rating when installed to the high-wind nailing pattern, but Owens Corning Duration and IKO Cambridge are solid choices with competitive warranties too. We’ll show you the wind rating documentation for whichever brand fits your roof and budget before you commit to anything.

AfterCommon Roofing Problems We See in Van Nuys Homes
- Ponding on low-slope ranch sections. The original tar-and-gravel systems on 1950s homes in Valley Glen crack after 60+ years of heat, and water pools near the scuppers. Once the decking gets wet, the repair stops being a coating job and becomes a tear-off.
- Shingle granule loss from UV exposure. Van Nuys regularly hits 100°F in summer, and the sun accelerates granule shedding on composition shingles. Homeowners see granules in the gutters and assume it’s cosmetic, but the shingle’s protective layer is gone and leaks follow.
- Flashing failures at parapet walls. Many mid-century ranch homes in the 91405 zip have parapet walls where the roof meets the wall. The original metal flashing corrodes and separates, and water tracks into the wall cavity. It’s a classic Van Nuys leak pattern.
- Unpermitted re-roofs from previous owners. We frequently find homes where a previous owner had the roof replaced without a permit eight to ten years ago. The shingles may look okay, but there’s no wind rating documentation and the nailing pattern often doesn’t meet LADBS standards.

FAQs About Roofing Company in Van Nuys
The LADBS requirement for the San Fernando Valley wind zone means your roof system, shingles, underlayment, and nailing pattern need to be documented for uplift resistance, typically 110 mph for architectural shingles like GAF Timberline HDZ when installed to the six-nail high-wind pattern. The manufacturer’s wind warranty only applies if the install follows that spec, and the permit record is what proves it. Call (341) 217-2677 and we’ll explain exactly what your roof’s rating needs to be before you compare quotes.
Because the original tar-and-gravel or wood shake roofs from the 1940s through 1960s are either past fire code or the decking underneath is compromised from decades of ponding and heat. A recover just hides the damage and adds weight the older framing might not handle. Once we inspect a ranch in Van Nuys and find rot or code issues, a tear-off is the only route that meets current LADBS standards.
Yes, directly. If a Santa Ana wind lifts shingles and you file a claim, the adjuster will ask whether the roof was installed to the current wind zone requirements. A permit record from LADBS that documents the high-wind nailing pattern and underlayment spec makes the claim straightforward. Without it, the insurer may argue the roof wasn’t installed to code and reduce or deny the payout. We pull permits on every roof we replace in Van Nuys for exactly that reason.
A proper Van Nuys quote includes the LADBS re-roof permit line, the specific nailing pattern for the wind zone, the underlayment type for low-slope sections, drip edge and flashing at all penetrations, and the manufacturer’s wind rating documentation. Cheap bids often quote shingles alone with a four-nail pattern, skip the permit, and leave the low-slope sections vulnerable to ponding. You’ll see the difference when you compare our line-by-line written quote side by side with theirs. Call (341) 217-2677 for a free estimate and we’ll walk you through every line.
On low-slope sections of Van Nuys ranch homes, we install a self-adhered ice and water shield over the entire low-slope area, followed by either a membrane system or elastomeric coating depending on the roof’s condition and pitch. We also check the drainage path to the scuppers and clear or adjust anything that’s causing water to stand. Our crew recently finished a tear-off on a 1952 ranch in Valley Glen where the original tar-and-gravel roof had ponded near the scuppers and cracked along the parapet wall. We installed new plywood decking, a full ice and water shield over the low-slope sections, GAF Timberline HDZ architectural shingles on the main roof, and new galvanized drip edge and flashing at all valleys and penetrations, then ran a water test before final inspection.

We’ll schedule a free estimate, send you the technician’s name and photo before the visit, and give you a written price before any work starts.
