Walnut Park's 1938 median house and what sits under old shingles
Census data puts the median Walnut Park home at 1938. These are small stucco cottages from before the war, and their roofs have usually been recovered more than once. Under the top layer there may be a second, then a third, then the original deck.
That original deck is the main unknown. Houses of that age can have wide-spaced boards rather than solid plywood, and long-term leaks leave soft or stained areas. Pre-war roofing layers may contain asbestos, so a lab test before anything is torn off is the sensible step when material looks suspect. Our roof replacement page explains how tear-off and decking checks work.

Small lots, little staging room and how a Walnut Park crew works
The community covers 0.7 square miles, and its lots are small. A roofing job needs somewhere to put a bin, a stack of materials and a ladder. Here that may be a narrow side yard, a short driveway or a curb space shared with the neighbors.
We walk the lot on the first visit and decide where each item goes. We keep vehicles off lawns where we can, cover plants, and plan a sweep with a magnetic roller at the end of each day. Reviewers in Van Nuys mention a second pass with a magnetic roller and thorough daily cleanup, and those are the habits we bring here.

Santa Fe, Pacific and Seville: the streets behind the rooflines
County planning documents describe higher residential density along Santa Fe Avenue, Pacific Boulevard and Seville Avenue, with Florence Avenue and Pacific Boulevard as the commercial hubs. Where homes sit that close, rooflines nearly touch and a ladder may stand on a neighbor's strip of side yard. We ask before we set up there.
The 2020 census counted 3,818 housing units and an average household of 4.08 people. Full households can lead to added rooms, a converted garage or a back porch, and those additions often carry shallow or flat roofs that tie into the main slope. That tie-in is where water finds its way in. Los Angeles Unified runs the neighborhood schools, including Walnut Park Elementary and Walnut Park Middle.
Los Angeles County permits next door to a city
As an unincorporated community, Walnut Park gets its building permits through Los Angeles County Public Works. Huntington Park and South Gate, which border it, are cities with their own departments. Two houses near the boundary can follow different rules, so confirm the agency before comparing quotes. Often a cool-rated product is needed when a re-roof goes past half the roof.
A Walnut Park roof visit from Van Nuys
From Van Nuys it is about 45 minutes by our estimate, and calling gets you a realistic arrival window. On the first visit we go over the shingles, flashing, vents and gutters, then follow up with a written estimate and photos. Flat porch or garage sections are covered under flat roofing, and ongoing leaks start at roof repair. For a leak, ask whether a same-day or next-day slot is open.
What customers say
“They also took care of the permit process, which made everything much easier for me.”
“I even saw Roger return later with a magnetic roller to check the ground again for any missed roofing nails, which showed real care and attention to detail.”

Roofing questions from Walnut Park
Who permits a roof replacement in Walnut Park?
Walnut Park is unincorporated, so building permits for a roof run through Los Angeles County Public Works. The neighboring city of Huntington Park has its own building department and its own process, so a quote written for a city address might not fit this process. Confirm the county requirements for your parcel before signing, and have the contract state who will be pulling the permit.
What is under the shingles on a 1930s Walnut Park house?
Often a second or third layer, and under that the original deck, which can be spaced boards or early sheathing with gaps. We tear off, count layers and probe the deck. Two existing layers mean a new roof is not allowed on top, so removal is common. We show soft areas to you and price them before any wood is replaced.
How do you protect a small Walnut Park yard during a tear-off?
We cover plants and walkways with tarps and plywood, run debris into a bin at the curb or driveway and clean up each day. A magnetic roller helps find missed nails after cleanup, a step that Van Nuys reviewers describe. The staging plan goes in your written estimate, so you know where everything will sit.
Services in Walnut Park
- Flat Roofing
Porches, rear rooms and garage roofs on small pre-war lots are often low-slope or flat. They hold water near walls, so seams and tie-ins to the main roof get close attention.
- Commercial Roofing
Shops and small mixed-use buildings in and around Walnut Park carry low-slope roofs with vents and equipment. Drains, parapet flashing and penetrations all get checked together before we recommend a fix.
- Roof Repair
Roofs on 1930s houses are often patched several times. Tracing the water back to its entry point comes first, so a repair lands on the real leak instead of another old patch.
- Roof Replacement
A 1938 median build year means layers and old spaced boards under the shingles are likely. Stripping the old roof reveals what is there, and soft areas are explained before any wood is replaced.
- Roof Permits
Walnut Park is unincorporated, so the county handles the permit while neighboring Huntington Park and South Gate use their own. This page explains what a re-roof permit involves and who should apply.
- Roof Flashing Repair
Several rounds of patches on 1930s cottages leave tar, caulk and mismatched metal at walls, vents and chimneys. We strip the old patch work back and reflash so the next repair is not another layer.
- Older Home Roof Replacement
Walnut Park's pre-war cottages can hide a second layer over spaced boards. This page covers what tear-off reveals on older decks and how soft boards are priced before any are replaced.
