Fast, Reliable Specialty Roofing Across North Hollywood
Specialty roofing in North Hollywood runs $8,500-$24,000 depending on system type, with most flat-roof replacements on postwar apartment buildings falling between $12,000 and $18,000. We’re usually on-site within 45 minutes for calls from the 91605, 91606, or 91609 ZIP codes, and we carry the membrane stock and fasteners to finish most jobs in a single visit.
We’ve been climbing North Hollywood roofs since 1984. We know the stucco-box apartments along Lankershim, the ranch homes near Magnolia Boulevard, and the 16-unit complexes on Vineland that still carry original 1960s built-up tar-and-gravel. The Valley floor here hits 105-110°F in summer, a full 15-20°F hotter than coastal LA, and the Santa Ana winds funnel straight through the Cahuenga Pass with concentrated force you don’t see in Burbank or Van Nuys. That combination - extreme heat, salt-laden wind, and aging multi-layer roofs - creates failure patterns we’ve learned to read before they become emergencies.

Our Specialty Roofing Services in North Hollywood
TPO Roofing
TPO is the workhorse for North Hollywood’s flat and low-slope re-roofs, especially since Los Angeles enforces California’s Title 24 cool-roof mandate on every replacement. The white reflective surface drops surface temperature dramatically compared to black modified bitumen or BUR gravel - critical when your roof is already baking at 110°F ambient. We install TPO from GAF and CertainTeed with mechanically attached or fully adhered systems, using stainless steel fasteners on properties within salt-air reach of the Cahuenga Pass corridor. Standard galvanized fasteners corrode in 3-5 years here. We’ve seen it. We don’t install them anymore on wind-exposed low-slope work.
Modified Bitumen
Torch-down and self-adhering modified bitumen still cover thousands of North Hollywood roofs from the 1970s and 1980s. The material performs well when installed correctly, but UV degradation along the San Fernando Valley’s inland basin weakens the adhesive bond at seams and edges. When the Santa Ana winds hit, those are the failure points. We inspect every modified bitumen roof for edge uplift, re-secure with proper termination bars, and replace only what’s failed rather than defaulting to full tear-off when it’s not warranted. Owens Corning and IKO supply our cap sheets, and we match existing granule color where partial repair makes sense.
Built-Up Roofing (BUR)
The original 1960s tar-and-gravel systems are still out there - on Vineland, on Lankershim, on the low-sloped ranch homes near Magnolia. Most have been patched and coated so many times the dead load exceeds what the wood-plank or early plywood deck was designed to carry. We tore off a sagging original 1960s BUR system off a 16-unit apartment complex on Vineland Avenue near Sherman Way. The successive patch-and-coat jobs had added so much dead weight that the plywood deck was bowed 3 inches in places, triggering an unexpected LADBS permit for full deck replacement. After structural repair, we installed a TPO cool roof meeting Title 24 solar reflectance requirements, using stainless steel fasteners throughout to prevent corrosion from the salt air blown up from the coast. That’s the reality of BUR work in North Hollywood: what looks like a membrane job often becomes a structural conversation.
Solar Ready Roofing
With Title 24 pushing solar readiness on new and replacement roofs, we’re installing compatible membrane systems and structural decking rated for future panel loads. North Hollywood’s intense UV and heat make solar economics compelling, but the roof beneath the panels needs to outlast the installation. We spec GAF and CertainTeed products with enhanced puncture resistance and plan the layout so future racking doesn’t compromise membrane seams.

Trusted Brands We Service in North Hollywood
We stock membrane, fasteners, and flashing for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For North Hollywood customers, that means no waiting two weeks for a TPO roll to ship from out of state. Our warehouse carries white TPO in common widths, modified bitumen cap sheets in granule colors matching local installations, and the stainless steel fasteners we now specify for low-slope work in wind-exposed Valley properties. We are authorized installers for every brand we carry, so manufacturer warranties stay intact.
Common Specialty Roofing Problems We See in North Hollywood Homes
- Fastener and flashing corrosion from salt-laden winds. The Cahuenga Pass funnels coastal air into North Hollywood’s flat Valley floor. Exposed galvanized fasteners on low-slope roofs show red rust within 3-5 years, compromising membrane attachment long before the membrane itself fails.
- Thermal splitting in single-ply membranes. Daily expansion from 110°F afternoon heat to 65°F nights creates tension at seams and penetrations. TPO and EPDM not properly tensioned or detailed split at stress points, especially on older decking that flexes.
- Wind uplift of modified bitumen edges after UV degradation. Santa Ana events lift loose edges where adhesive has crystallized from years of Valley UV exposure. The damage often starts at corners and parapet walls, invisible from the ground until water enters.
- Structural deck sag under multi-layer BUR dead load. Original 1960s tar-and-gravel plus successive coatings and patches can exceed 15 pounds per square foot. The wood-plank or early plywood deck beneath was never engineered for that weight, and sagging triggers LADBS permit requirements for full replacement.
Pricing for Specialty Roofing in North Hollywood, CA
A typical TPO re-roof on a 1,500-square-foot North Hollywood duplex runs $12,000-$16,000, including tear-off of existing membrane, deck repair up to 10% of surface area, and Title 24-compliant cool-roof installation. Modified bitumen replacement on similar footage runs $10,500-$14,000. Built-up roofing tear-off with structural deck replacement, LADBS permits, and new TPO installation can reach $18,000-$24,000 on multi-unit properties where successive patch layers have compromised the substrate.

FAQs - Specialty Roofing in North Hollywood
Standard galvanized fasteners corrode in 3-5 years on North Hollywood’s low-slope roofs because salt-laden winds from the Cahuenga Pass accelerate rust. Stainless steel fasteners cost more upfront but maintain structural integrity through the full membrane lifespan. We specify stainless on every wind-exposed Valley installation now - it’s not an upsell, it’s the standard that holds. Call (877) 367-1429 to discuss your specific roof; estimates are free.
If the sag exceeds 1 inch in 10 feet or the decking shows visible bowing, LADBS typically requires a structural engineer’s letter before issuing a re-roof permit. We document the condition during our initial inspection and can recommend engineers we’ve worked with on North Hollywood properties. The 16-unit complex we repaired on Vineland near Sherman Way needed exactly this step - the bowed plywood was 3 inches out of plane. Call (877) 367-1429 and we’ll assess whether your deck has reached that threshold; estimates are free.
Yes. Any re-roof in the 91605 ZIP code that removes more than 50% of the existing roof surface must install materials meeting Title 24 solar reflectance and thermal emittance standards. For low-slope residential roofs, that typically means white TPO or coated modified bitumen with minimum 0.70 initial reflectance. We verify product compliance before quoting and handle the documentation for LADBS inspection. Call (877) 367-1429 for a Title 24-compliant estimate; there’s no charge to review your options.
Surface repairs are possible if the deck is sound and there’s only one or two existing layers. Most 1960s BUR systems in North Hollywood have accumulated three or more patch-and-coat applications, and the dead load often exceeds safe capacity. We inspect the deck structure and layer count before recommending - we don’t default to tear-off when repair is viable, and we don’t patch over a deck that’s already sagging. Call (877) 367-1429 for an honest assessment; estimates are free.
Inspect within 30 days after each significant Santa Ana event, and schedule a professional inspection annually before summer heat intensifies. Look for lifted edges, separated seams, and displaced gravel on BUR surfaces. The concentrated wind through the Cahuenga Pass creates uplift stress more severe than neighboring Burbank or Van Nuys experience, so North Hollywood low-slope roofs need closer monitoring. Our $89 seasonal inspection includes photo documentation and a written condition report. Call (877) 367-1429 to schedule.
