Flashing Repair in Los Angeles, CA

Flashing Repair in Los Angeles, CA

Flashing repair in Los Angeles typically costs between $350 and $900 for most residential jobs, depending on where the flashing sits and how much of it has failed. We complete most flashing repairs the same day we diagnose the problem, and every repair comes with a written guarantee before our crew leaves your property. If you’re seeing water stains on a ceiling or along an exterior wall, call us at (213) 674-2890 and a live person will answer, day or night.

Flashing is the metal material, usually galvanized steel, aluminum, or copper, that seals the joints where your roof meets a vertical surface. Chimneys, skylights, vent pipes, dormer walls, and the valleys where two roof planes meet all rely on flashing to keep water moving down and away. When flashing corrodes, pulls loose, or was installed incorrectly in the first place, water gets underneath the shingles and into the roof deck. That’s where the real damage starts. Tilehurst Roofing Los Angeles handles flashing repair as part of our broader Roof Repair work, and it’s one of the most common calls we get from homeowners across Los Angeles.

We’re a Kingswell family roofing company, founded in 2000, and our flashing repairs follow the same Kingswell Way as every other job we do: say the price before the work, arrive in the window we gave, put the guarantee in writing, and come back if it fails. Greg Holloway leads our Los Angeles team, and every technician who climbs onto your roof is background-checked and in uniform. You’ll know exactly who is working on your home.

• A live person answers our phones 24/7, including weekends and evenings, at (213) 674-2890.

When You Need Flashing Repair

Flashing fails quietly. By the time water shows up on your ceiling, the flashing has usually been compromised for months. Here are the signs we see most often across Los Angeles neighborhoods, from Sherman Oaks to Eagle Rock to Westchester:

• Water stains on ceilings or upper walls that appear after rain, especially in rooms directly below a chimney, skylight, or where the roofline meets an exterior wall. In Los Angeles, where rain comes in concentrated bursts, a small flashing gap can move a surprising amount of water in a single afternoon.
• Visible rust or corrosion on metal flashing around chimneys or vent pipes. Los Angeles’s coastal air carries salt that accelerates corrosion on exposed metal, particularly in neighborhoods closer to the coast like Playa del Rey or San Pedro.
• Loose or lifted flashing that has separated from the roof or wall surface. This often happens after the seasonal Santa Ana wind events, when gusting air gets under the metal edges and pries them upward.
• Granules from asphalt shingles collecting in gutters near flashing points. When flashing leaks, it saturates the surrounding shingles and underlayment, causing premature wear that shows up as granule loss.
• Daylight visible from the attic around pipes, chimneys, or angled roof joints. If you can see light through a flashing gap, water is already getting in.
• Peeling paint or staining on exterior walls just below a roofline joint. This indicates water is escaping behind the flashing and running down the wall cavity instead of into the gutter.

If any of these sound familiar, don’t wait for the next rain. Los Angeles may be dry most of the year, but when storms arrive, they arrive hard. A failing flashing joint turns a routine storm into an interior water damage claim. Call (213) 674-2890 and we’ll send someone to look, usually the same day.

Our Flashing Repair Process

We keep flashing repair straightforward. No mystery, no upselling, no pressure. Here’s exactly what happens when you call Tilehurst Roofing Los Angeles:

1. You call, a person answers. Not a voicemail, not an answering service, not a callback queue. A live person picks up the phone at (213) 674-2890, any hour of any day. We’ll ask about what you’re seeing, schedule a visit in a window that works for you, and confirm it in writing.
2. We inspect the flashing and the surrounding roof. Our technician examines the failed flashing and also checks the area around it – the underlayment, the decking, the shingles or tiles adjacent to the joint. Flashing failure often causes secondary damage, and we want you to know the full picture before we quote a price. In neighborhoods like Silver Lake and Mount Washington with older homes, we often find original flashing from the 1950s or 1960s that’s simply reached the end of its service life.
3. You get a written price before any work starts. The quote includes material, labor, and disposal, itemized so you can see exactly what you’re paying for. This is never negotiated after the fact. If we find additional damage during the repair, we stop, show you, and get your approval on a written change order before proceeding.
4. We replace or reseal the flashing. Depending on the condition, we either remove and replace the entire flashing assembly with new metal or, when the existing flashing is structurally sound, clean and reseal the joints. We use materials from manufacturers including GAF, Atlas, and Tamko, matched to your existing roof profile. When we replace step flashing along a wall, we re-layer it correctly with the shingle courses so water sheds properly.
5. We test the repair and document everything. Before the crew leaves, we water-test the repaired area where practical and walk the roof to confirm nothing was disturbed. You receive a written guarantee covering the repair, and every flashing repair falls under our 365-Day Done Right Promise: if it fails within a year, we return and correct it at no charge.

That last point matters. We know homeowners in Los Angeles have been burned by contractors who repaired a leak, took the check, and disappeared when it leaked again. The Kingswell Way was built for people who’ve had that experience. The written guarantee is the floor, not a premium add-on.

Flashing Repair Pricing in Los Angeles

Most flashing repair jobs in Los Angeles fall into the $350 to $900 range. Small, accessible repairs, like resealing a vent pipe boot or a short section of step flashing, sit at the lower end. Full replacement of chimney flashing or long runs of wall flashing with custom-bent metal run higher. Here is what we typically see across the city:

Repair Type	Typical Range	What’s Included
Vent pipe boot reseal or replacement	$350 – $500	New rubber or metal boot, sealant, water test
Step flashing repair (short run, up to 10 linear feet)	$400 – $650	Remove and re-layer flashing with shingle courses, reseal
Chimney flashing reseal	$450 – $700	Clean, reseal, replace counter-flashing as needed
Skylight flashing replacement	$500 – $800	Remove old flashing, install new kit, seal curb, water test
Full chimney flashing replacement with new metal	$600 – $900	Custom-bent metal, remove old flashing, full reinstallation
Long wall flashing run (over 10 linear feet)	$650 – $1,100+	Custom metal fabrication, full re-layering, sealing

Two things move the price in Los Angeles specifically. First is metal type: galvanized steel is the standard, but aluminum costs slightly more and copper significantly more. We’ll show you options across our manufacturer lineup, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and let you decide based on your home’s roof profile and your budget. Second is access: flashing on a steep second-story roof or a chimney with limited ladder access takes more time and requires additional safety rigging. We factor that into the written quote upfront, so there are no surprises when the invoice comes.

Every quote is free. Call (213) 674-2890, tell us what you’re seeing, and we’ll schedule an inspection. You’ll have a written price in hand before you commit to anything.

Why Flashing Fails in Los Angeles

Los Angeles has a reputation for easy weather, and in many ways it is. But the specific conditions here create predictable flashing failures. Understanding why your flashing failed helps you make a smarter repair decision.

First, the coastal air. Homes west of the 405, in neighborhoods like Mar Vista, Culver City, and Westchester, get consistent marine-layer moisture. Salt-laden air accelerates corrosion on galvanized steel flashing. We regularly see homes within five miles of the coast with flashing that looks twenty years older than the roof itself. Aluminum flashing holds up better in these conditions, which is why we often recommend it for coastal Los Angeles homes.

Second, the heat-and-sun cycle. Los Angeles sees intense UV exposure, especially in the San Fernando Valley, where summer temperatures routinely cross 100 degrees. Over years, the thermal expansion and contraction of metal flashing against stucco and shingles breaks down sealant bonds. The metal expands, the sealant cracks, and the next rain finds the gap. In Granada Hills and Woodland Hills, we see this exact pattern on south-facing roof planes more than any other.

Third, the wind. Santa Ana events push sustained gusts through the canyons and across the foothills. Flashing that was installed with marginal fastening or aging sealant takes a beating during these events. Angelenos in Pasadena, Altadena, and the lower San Gabriel foothills are particularly familiar with this.

And fourth, original construction quality. A significant share of Los Angeles housing stock went up between 1945 and 1980, and much of it used thin, low-grade flashing metal. In neighborhoods like West Adams, Leimert Park, and parts of the Valley, we work on homes where the original flashing is still in place and well past its service life. Homeowners are often surprised to learn the flashing has been there since the Eisenhower administration.

None of this means your roof is failing. Flashing is a replaceable component, and a proper repair extends the life of the entire roof. But it does mean you should choose flashing metal appropriate to your specific Los Angeles microclimate. We’ll walk you through those options when we inspect your roof.

Flashing Materials We Use

Not all flashing is the same, and the right choice depends on your home’s existing roof materials, your location within Los Angeles, and your budget. We carry flashing solutions from seven major manufacturers, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we’ll help you choose the right one for the job.

For most asphalt shingle roofs, galvanized steel flashing from GAF or Atlas is the standard. It’s durable, cost-effective, and integrates cleanly with the shingle system. For coastal Los Angeles homes, we often recommend aluminum flashing, which resists salt-air corrosion better than galvanized steel. For flat or low-slope roofs, which are common in mid-century Los Angeles architecture, the flashing system integrates differently, and we’ll spec the appropriate material from our manufacturer lineup for a watertight seal.

Some homeowners ask about copper flashing. It’s beautiful and it lasts for decades, but it costs two to three times more than steel or aluminum. If you have a historic home in Angelino Heights or Hancock Park with visible flashing that should match the architectural character, copper might be worth it. We’ll give you all the options in writing, with prices, and let you decide.

Flashing Repair vs. Roof Replacement

Isolated flashing failure almost never means you need a full roof replacement. Flashing is a component, and when it fails while the surrounding roof is still in good condition, the right move is a targeted repair. We’ll tell you honestly if we think a full replacement is the better long-term investment, and we’ll show you the evidence. In most cases, though, a proper flashing repair gives your roof many more years of service for a fraction of the cost.

Here’s the test we apply: if the roof decking under the failed flashing is solid, with no rot or saturation, and the shingles or tiles around the flashing still have life, repair is the clear choice. If the water has been getting in for a long time and the decking is compromised, replacement of the affected section may be necessary, and sometimes a full roof replacement becomes the smarter financial decision. We’ll walk you through that math on site, with your written quote in hand.

How do I know if my roof flashing is leaking?

If you notice any of these, call (213) 674-2890 and we’ll inspect the flashing and the surrounding roof at no charge.
