Older Home Roof Replacement in Los Angeles, CA
An older home roof replacement in Los Angeles is mostly a deck-and-details job. Homes from the 1920s through the 1960s often have spaced boards, shallow pitches, small attics and additions at different heights, so the plan has to start with what is under the shingles. We look at that first and price it in writing.

Old roofs fail in old ways. A house from the 1950s or earlier has seen sun, wind and winter storms for decades, and its roof was built to the standards and materials of its day. If you are weighing an older home roof replacement in Los Angeles, the deck, the vents and the places where roof planes meet matter as much as the shingle you pick.
What does an older home roof replacement include?
A full tear-off, with more attention to what sits under the shingles. The scope should list:
- Removal of every layer, with the count confirmed on the roof
- Deck review, with spaced boards covered and rotted boards replaced
- New underlayment, drip edge and flashing at chimneys, walls and additions
- Vent upgrades where intake or exhaust is thin
- Shingles and ridge cap, plus a magnetic sweep of the yard
When an older home's roof is ready to be replaced
Age is a clue, not a verdict. Look for the signs that tell you the roof as a whole has finished its work:
- Curling or bare shingles across more than one slope
- Granules in the gutters, a sign the shingle surface is shedding
- Stains on ceilings that come back after repairs
- Daylight in the attic between the boards
- A sag along the ridge or between rafters
Each of these can have a smaller cause, so we check the attic and flashing before recommending a full job. Our guide to recurring ceiling stains can help you tell the difference.
Roof replacement on a 1950s house in the San Fernando Valley
A 1950s ranch is usually a long, low roof with a shallow pitch, a chimney and a few small vents. Shallow pitch means water sheds slowly, so underlayment and flashing carry more of the load. Many of these homes have been re-roofed once or twice, which puts layers and old nail holes on the list for the tear-off. Our roof tear-off page explains how those layers come off.
Heat plays a part too. Van Nuys averages about 77 days a year at 90°F or hotter by NOAA's normals, and a thin attic cooks the roof from below. Our post on mid-century San Fernando Valley roofing goes further into what these homes have in common.
Craftsman and historic home roofing rules in Los Angeles
Craftsman bungalows have wide eaves, exposed rafter tails and low gables, and those details are why the work is slower. Fascia, trim and the edge of the roof get handled by hand. If your house has a designation, an overlay or a specific plan, rules may limit the material, the color or the process. In the City of Los Angeles, the certificate-of-compliance route under LADBS does not apply where a historic designation or specific plan restricts re-roofing.
The City of Los Angeles Office of Historic Resources lists reroofing among the projects it screens in Historic Preservation Overlay Zones, and review of significant exterior work follows the Secretary of the Interior's Standards for Rehabilitation (OHR screening checklist). Incorporated cities run their own reviews. Ask your preservation office before choosing a material. The contract should also name who pulls the permit.
What is spaced sheathing, and does it change a reroof?
Spaced sheathing is a roof deck of boards laid with gaps between them, common under older wood shingle or tile roofs. Modern asphalt shingles need a solid surface, so spaced boards usually get a layer of plywood over or between them before the new roof goes on. We confirm that after the old roof is off and the boards are visible.
Rotted boards are replaced either way. Board repair is a priced item, not a surprise on the invoice.
How an older home re-roof is scheduled
An older home gets a longer look before the work starts. This is the order we follow:
- Walk the roof and attic. We photograph the deck, vents, chimney and flashing.
- Check records. Past permits, invoices or insurer letters help date the existing roof.
- Choose materials and color. Samples are brought to the home so you see them against the stucco.
- Set the permit path. The contract names who handles the permit.
- Strip, inspect and repair. Layers come off and boards are replaced where needed.
- Dry in and install. Underlayment, flashing, vents and shingles go on in sections.
What raises the price of an older home re-roof?
Cost is driven by what the tear-off finds, not by the age of the house. Extra layers, board replacement, a plywood overlay on spaced decking, new vents, chimney work and tight access add labor. Fascia and soffit repair can be added when boards are rotted. For scale, Angi estimates roof replacement in Los Angeles at roughly $4 to $12 per square foot, averaging about $8.60, or about $17,200 for a typical 1,700 square foot home (accessed November 2026). We write the base price first and list each extra as its own line, so the total is not a surprise.
Insurers consider roof age and condition, so ask yours what they require before you plan the work.
Why Clear Shield for older home roof replacement in Los Angeles
On older roofs, reviewers mention hidden problems found and explained: a poorly placed roof vent, fascia damage and the need for bird blocking. They also describe plywood replaced after it was shown to them, plus pictures and measurements sent before quoting.
What Van Nuys customers say about hidden roof problems
“I recently had my old shingle roof replaced with a new CertainTeed Pro line roofing system, and I am very happy with the results.”
“We were deciding between a standing seam metal roof and asphalt shingles, and frederick was a great guide who helped us understand the pros and cons so we could make the best choice for our home and budget.”
“They also took care of the permit process, which made everything much easier for me.”

We cover mid-century neighborhoods across the area. Burbank and Monterey Park have 1950s homes, some on sloped lots. Florence-Graham and Ladera Heights are unincorporated, so their permits go through the county. For vent problems, see our attic ventilation page. For fire-zone material questions, read about Class A fire-rated roofing or solar-ready roof replacement.
Older Home Roof Replacement: common questions
What should owners of 1950s homes expect during a re-roof?
Expect the tear-off to reveal the deck. Many 1950s Valley ranches have spaced boards or thin plywood, and a few have more than one layer of shingles. We photograph what we find, price any board repair before doing it, and check vents, chimney flashing and plumbing stacks, since older ones fail first. Tell us if you have old permits or invoices for earlier roofing.
Can you blend a roof across an old section and a taller addition?
Usually, yes. The new shingle runs across both sections so the color matches, and metal flashing is built where the taller wall meets the older roof. Additions often have a different pitch, so a shallow section may need a different underlayment or a low-slope system. We walk the joint with you and quote each section separately.
Do older homes need extra ventilation work during a re-roof?
Often. Older attics tend to have a few small gable or roof vents and little intake at the eaves, which traps heat in summer. A re-roof is the cheapest time to correct it. One reviewer describes a poorly placed roof vent found on a Van Nuys job. We look at intake and exhaust together and quote any change as its own line.
Do older home roof replacements in Los Angeles need new decking?
Sometimes all of it, sometimes none. Spaced boards generally need a solid layer, usually plywood, before modern shingles go on. Solid plywood or board decking may only need patches where it is stained or soft. We decide board by board once the old roof is off, and one reviewer describes plywood being replaced and explained first.
How do you re-roof a Craftsman bungalow without damaging the rafter tails?
By working from the roof, not from the eave. Exposed rafter tails and wide fascia boards are fragile, so we keep ladders off them, protect painted edges and replace only rotted pieces. New drip edge sits above the trim line. If the wood is already soft, we show you before touching it and price the repair separately.
Is asbestos a concern on a 1950s Los Angeles roof?
It can be. Some older roofing materials may contain asbestos, and houses of that age may still carry original layers. If we see signs, we recommend lab testing before removal. We do not run the test, and SCAQMD Rule 1403 sets survey and notification rules for regulated work. The result decides how the tear-off is handled.
