Flashing Work for Van Nuys's Postwar Homes

Roof flashing in Van Nuys is one of the most common repair needs on the flat-lot, postwar housing stock that defines much of this San Fernando Valley community — from the quiet residential blocks of Lake Balboa near Woodley Park to the denser streets of Valley Glen and Delano. Homes built in the 1950s and 1960s across zip codes like 91405 and 91406 often carry original galvanized flashing that has corroded, lifted, or been buried under successive layers of roofing over the decades. When flashing fails at a chimney, skylight curb, parapet wall, or roof-to-wall transition, water finds its way in long before the shingles themselves give out. Van Nuys sits within the City of Los Angeles, so any permitted flashing or roofing work goes through Los Angeles's building department. Roof Repair & Construction Inc. works throughout Van Nuys and the surrounding communities — including Sherman Oaks, Panorama City, and Reseda — bringing the same straightforward, factual approach to every assessment.

Van Nuys Flashing Failures

Where Van Nuys Roofs Leak at the Flashing

On the postwar ranch-style and bungalow homes common throughout Van Nuys, flashing failures tend to cluster at the same points: chimney step and counter-flashing, the base of any skylight curb, and the horizontal joint where a roof plane meets a vertical wall — a detail found on nearly every home with a covered porch or rear addition. In the Sepulveda and Delano areas, flat-roof carports and low-slope additions add parapet wall flashing and interior drain flashing to the list. Catching these failure points early prevents the kind of deck rot that turns a flashing repair into a full tear-off. Call (323) 474-1088 to schedule an assessment.

Flashing Materials & Options

Flashing Metal Choices for Van Nuys Homes

Galvanized steel was the standard on most homes built in Van Nuys during the postwar decades, and while it holds up for many years, it eventually corrodes — especially where it contacts dissimilar metals or sits under standing moisture. Aluminum is a common replacement choice on composition shingle roofs; lead-coated copper or heavier aluminum is often used at chimney counter-flashing where a tighter seal and longer service life matter. On flat and low-slope sections — the kind found on many Sepulveda-area properties and light commercial buildings near Van Nuys Airport — flashing integrates directly with the membrane system, whether that's torch-down modified bitumen or TPO. Call (323) 474-1088 to discuss which material fits your roof.

Flashing Metal Choices
Aluminum step and counter-flashing for composition shingle roofs
Lead-coated or heavier aluminum at chimney and masonry details
Galvanized steel replacement where original material has corroded
Membrane-integrated flashing for torch-down and TPO flat roofs
Prefabricated pipe boot and vent flashing replacements
Drip edge and rake flashing as part of a full re-roof
City of LA Permits

Roofing Permits for Van Nuys Flashing Work

Van Nuys is part of the City of Los Angeles, so building permits and inspections for roofing and flashing work are handled by the Los Angeles Department of Building and Safety (LADBS) — not a separate municipal building department. Isolated flashing repairs often fall below the permit threshold, but a full re-roof or significant deck replacement will typically require a permit and inspection. Roof Repair & Construction Inc. treats LADBS as the authority on what applies to a given property and can walk you through what to expect. Call (323) 474-1088 with questions about your specific project.

Flat Roof Flashing

Flashing on Van Nuys Flat and Low-Slope Roofs

A meaningful share of Van Nuys properties — particularly in the Delano and Sepulveda areas, and on commercial strips near the Van Nuys Airport corridor — have flat or low-slope roofs where flashing details differ substantially from pitched-roof work. Parapet walls need continuous cap flashing that sheds water away from the wall-to-deck joint; interior drains and scuppers need properly integrated flashing collars to prevent ponding water from wicking under the membrane. Roof Repair & Construction Inc. handles these details as part of torch-down, modified bitumen, and TPO installations. Call (323) 474-1088 to talk through your flat roof situation.

Questions

Frequently Asked Questions

How much does roof flashing cost in Van Nuys?
Flashing costs in Van Nuys vary depending on the scope — a single chimney counter-flashing repair is a much smaller job than replacing all the step flashing, valley flashing, and drip edge on a full re-roof. The condition of the underlying deck, the roof type (pitched shingle vs. flat membrane), and the metal specified all affect the price. Roof Repair & Construction Inc. assesses each property individually before quoting. Call (323) 474-1088 to get a specific estimate for your home.
Can flashing be repaired without replacing the whole roof in Van Nuys?
Yes — in many cases, isolated flashing at a chimney, skylight, or wall transition can be repaired or replaced without disturbing the rest of the roof, provided the surrounding shingles or membrane are still in serviceable condition. On Van Nuys homes from the 1950s and 1960s, however, it's common to find that old flashing has been layered over rather than replaced, which sometimes means pulling back more material than expected. A proper assessment determines what's actually needed. Call (323) 474-1088 to schedule one.
How long does a flashing repair or replacement take on a Van Nuys home?
A targeted flashing repair — say, re-doing the counter-flashing on a single chimney — is typically a one-day job. Replacing flashing across an entire roof as part of a full tear-off and re-roof takes longer, generally two to four days depending on the size of the home and whether deck repairs are needed. Flat-roof flashing work on a low-slope addition or carport can often be completed in a single day. Call (323) 474-1088 for a timeline specific to your Van Nuys property.
What happens to the old flashing when a Van Nuys home gets a full re-roof?
On a full tear-off, all existing flashing is removed along with the old roofing material and inspected. Flashing that is corroded, improperly installed, or incompatible with the new roof system is replaced as part of the re-roof — this is standard practice, not an add-on. On many Van Nuys homes built in the postwar decades, the tear-off reveals original galvanized flashing that has been covered rather than replaced over the years. Call (323) 474-1088 to discuss what a full re-roof typically uncovers on homes in your area.
How do I know if the flashing on my Van Nuys home has failed?
The most direct sign is water intrusion at a specific point — a stain on the ceiling near a chimney, skylight, or exterior wall after rain. From the roof, lifted or separated flashing, visible rust staining, gaps at the flashing-to-masonry joint, or caulk that has cracked and pulled away are all indicators. On older Van Nuys homes, flashing failure is sometimes hidden under a layer of roofing cement that was used as a temporary fix. Call (323) 474-1088 and Roof Repair & Construction Inc. can take a look.
Does flashing work on a Van Nuys home require a City of LA permit?
Van Nuys falls under the City of Los Angeles, so LADBS is the permitting authority. Isolated flashing repairs — patching a single leak point, for example — often don't require a permit, but a full re-roof that includes new flashing typically does. Roof Repair & Construction Inc. treats LADBS as the authority on what a specific project requires and can help you understand the process. Call (323) 474-1088 to talk through your project's scope.
What flashing details are specific to flat or low-slope roofs in Van Nuys?
Flat and low-slope roofs — common on additions, carports, and some original structures in the Delano and Sepulveda areas of Van Nuys — rely on flashing that integrates directly with the membrane rather than overlapping shingles. Key details include parapet cap flashing, interior drain collars, and scupper flashing, all of which must be watertight at the membrane-to-metal transition. These details differ from pitched-roof flashing and require familiarity with torch-down and TPO systems. Call (323) 474-1088 to discuss your flat roof's flashing needs.
My Van Nuys home has both a pitched shingle roof and a flat-roof addition — can the flashing at that transition be addressed in one visit?
Yes — the joint where a pitched roof meets a flat or low-slope section is one of the most common leak points on Van Nuys homes with rear additions or covered patios, and it's a single scope of work. The flashing at that transition needs to work with both the shingle system above and the membrane system below. Roof Repair & Construction Inc. handles both roof types and can assess the full transition in one visit. Call (323) 474-1088 to set up an appointment.
