We find the failed flashing, fix it, and test it before we leave.
Storm Damage Flashing Repair Altadena CA: What It Actually Involves
Storm Damage Flashing Repair Altadena CA is roof flashing repair that restores the metal and sealant joints wind and rain have torn loose. Flashing is the bent metal that keeps water out of the seams where your roof meets a chimney, wall, skylight, or vent. After a storm, that metal can lift, crack, or pull free, and water finds the gap within minutes. We reseat, reseal, or replace the damaged pieces so the roof sheds water again.
Altadena sits right against the San Gabriel Mountains, so winter storms hit harder here than in the flat parts of Los Angeles County. Wind-driven rain pushes sideways under lifted step flashing, and the freeze-thaw swings in January crack old sealant. If you have water staining near a chimney or a drip at a skylight, that is usually storm damage flashing repair in Altadena, California territory, not a full roof replacement. We see it most on homes built before 1980 with original galvanized steel.
Why Altadena Homeowners Fix Flashing After Storms
Flashing damage is small, cheap to fix, and expensive to ignore. These are the four outcomes our Altadena customers care about most when they call us after a storm.
Stop Active Leaks Fast
Water moves fast through a failed flashing joint. We target the leak first, seal the opening, and stop the intrusion the same day we arrive. Most storm-related flashing calls in Altadena are resolved in two to four hours, which keeps a small drip from turning into a ceiling repair and a mold problem.
Protect Your Ceiling and Insulation
A flashing leak rarely shows up where it starts. Water travels along rafters and drips ten feet away, soaking insulation and drywall. Fixing the flashing at the source protects the attic, the ceiling, and the paint. One Altadena customer avoided a $2,800 drywall and insulation replacement with a $340 flashing repair.
Keep the Repair Small
Storm damage flashing fix near me calls are usually about one joint, not the whole roof. When we catch it early, we replace a single section of step flashing or a vent pipe boot instead of tearing into shingles. That keeps the job under a few hundred dollars and preserves the rest of the roof.
Match Altadena Building Stock
Altadena has a lot of older homes with original chimney flashing and narrow roof-to-wall clearances. We carry copper, galvanized steel, and lead in the truck so we can match what is already there. That matters on historic homes near Christmas Tree Lane, where a mismatched patch stands out for decades.
How Our Storm Damage Flashing Repair Process Works
You get a clear sequence from the first call to the final water test. Here is exactly what happens when you book storm damage flashing repair with us in Altadena.
Call and Triage
You call or book online and describe where the water is showing up. We ask about the storm, the room, and the roof type. If the leak is active, we treat it as an emergency storm damage flashing fix in Altadena and schedule the visit for the same day or the next morning.
Roof and Attic Inspection
We inspect the roof at the flashing joints and check the attic for water trails. A roofing hammer and pry bar let us lift shingle edges without breaking them. We photograph the failed flashing, the cracked sealant, and any corroded metal so you can see the problem before we quote the fix.
Diagnosis and Pricing
We tell you what failed and what it takes to fix it, then give you one price for the repair. Most flashing repairs in Altadena run $180 to $650 depending on how much metal has to be replaced. You approve the price before any work starts.
Repair and Sealing
We remove the damaged flashing, cut new metal with tin snips or a hand seamer, and set it with butyl tape and roofing cement. Counter flashing and step flashing get locked into the mortar or wall, then sealed with polyurethane sealant. The repair takes two to four hours on a typical Altadena home.
Water Test and Cleanup
We run water over the repaired joint and watch it from the attic. If it stays dry, we clean the gutters of metal scraps, sweep the driveway with a magnet for nails, and walk you through what we did. You get a written summary of the repair and the materials we used.

Why Altadena Calls Us for Storm Damage Flashing Repair
We are a local roof flashing repair company, not a storm-chasing crew. That means we are still here next year when you need the flashing checked again.
Same-Day Storm Response
When a storm rolls through Altadena, we hold slots open for active leaks. Most emergency storm damage flashing fix Altadena calls get a crew on site within 24 hours. We tarp if the rain is still coming and complete the permanent repair as soon as the roof is dry.
Materials That Last
We use copper, galvanized steel, and lead flashing instead of thin aluminum on exposed joints. Butyl tape and polyurethane sealant hold up to Altadena's UV and freeze-thaw cycles far better than standard roofing cement. That is why our flashing repairs carry a five-year workmanship warranty.
Local Code Knowledge
Altadena falls under Los Angeles County building rules, and flashing has to be installed to specific lap and clearance standards. We know what inspectors look for on kickout flashing and counter flashing, so the repair passes without a second visit. We handle the paperwork when a permit is required.
Honest Scope, One Price
We quote the flashing repair, not a new roof. If the damage is limited to one joint, that is all we fix. Customers searching for storm damage flashing repair near me Altadena CA tell us the same thing: they want the leak stopped without a sales pitch for a full replacement.
What Our Storm Damage Flashing Repair Includes
Every flashing repair starts with a full inspection of the joints most likely to fail in a storm. We fix what is broken, seal what is sound, and tell you plainly if something else needs attention.
What's Included
Chimney Flashing Repair
We reset loose counter flashing, replace rusted step flashing, and seal the mortar joint where the chimney meets the roof. Leaking chimney flashing is the number one storm call we get in Altadena, and it is usually fixed in a single visit.
Skylight and Vent Sealing
Skylight frames and vent pipe boots take the brunt of wind-driven rain. We replace cracked boots, reseal the curb, and check the interior for water intrusion at skylights. A failed vent pipe boot can dump water straight into your attic insulation.
Step and Kickout Flashing
Improper step flashing installation and missing kickout flashing send water into walls instead of the gutter. We rebuild the step flashing course by course and add kickout flashing at wall ends so water is directed away from the siding.
Sealant and Metal Replacement
Cracked flashing sealant gets cut out and replaced with polyurethane sealant. Corroded flashing is removed and replaced with matching metal. We use tin snips, a hand seamer, and a seam roller to shape and lock each piece into place.
Water Test and Report
After the repair, we run water over the joint and confirm it is dry from the attic side. You get photos of the before and after, a list of materials used, and a note on what to watch for during the next storm season.
Storm Damage Flashing Problems We Solve in Altadena
Most storm leaks trace back to one of a handful of flashing failures. Here is what we see most often and how we fix it.
Leaking chimney flashing after heavy rain
Water runs down the chimney chase and stains the ceiling or fireplace wall, and the damage spreads with every storm.
We pull the old counter flashing, replace the step flashing, and reseal the mortar joint with polyurethane sealant. The chimney gets a new water path that sends rain to the gutter instead of into your attic.
Corroded or cracked flashing sealant
Old sealant shrinks and cracks within a season, opening a gap that lets wind-driven rain straight through the joint.
We cut out the failed sealant, clean the metal, and apply a fresh bead of polyurethane sealant rated for roof temperatures. On badly corroded metal, we replace the flashing section entirely with copper or galvanized steel.
Missing kickout flashing at wall ends
Without a kickout, roof water runs down the wall and rots siding, sheathing, and the top plate of the wall framing.
We fabricate and install kickout flashing at every roof-to-wall termination. It is a small piece of metal that redirects water into the gutter and prevents the wall damage we see on a lot of Altadena homes.
Water intrusion at skylights and vents
A failed vent pipe boot or skylight curb seal leaks directly into the attic, soaking insulation and creating a mold risk within weeks.
We replace the boot or reseal the skylight curb, then check the decking underneath for soft spots. If the wood is sound, the repair is quick. If it is not, we tell you before we close it up.
When Altadena Homeowners Call Us for Flashing Repair
A winter storm peels back step flashing along a second-story wall in West Altadena.
We inspect the wall joint, replace the lifted step flashing, and add a new kickout at the bottom of the run. The repair takes about three hours and uses copper to match the existing metal.
The wall stays dry through the rest of the rainy season, and the siding does not need to be replaced.
A homeowner near Rubio Canyon notices a brown stain spreading on the ceiling below the chimney.
We trace the stain to leaking chimney flashing, replace the counter flashing, and reseal the mortar joint. The attic gets a full check for wet insulation while we are up there.
The ceiling stain stops growing, and the customer avoids a drywall and insulation replacement.
An older home on Christmas Tree Lane has original galvanized flashing that has rusted through.
We fabricate new flashing on site with a flashing brake, matching the profile of the original pieces. The new metal is copper, which will outlast the roof itself.
The historic look is preserved, and the flashing will not need another repair for decades.
A vent pipe boot cracks after a summer of UV exposure and the first fall rain leaks into the attic.
We replace the boot with an EPDM unit rated for high heat, reseal the base, and check the surrounding shingles for damage. The job takes under two hours.
The attic stays dry, and the new boot handles UV and rain for years.
Tools and Methods We Use on Flashing Repairs
Tools & Equipment
Flashing brake
Bends custom metal flashing on site to match the exact angles of your chimney, wall, or skylight curb. This is how we get a precise fit on older Altadena homes.
Tin snips and hand seamer
Cuts and folds copper, galvanized steel, and aluminum flashing to size. The hand seamer locks seams tight so water cannot work its way between layers.
Caulking gun with polyurethane sealant
Applies a controlled bead of sealant at the flashing edge. Polyurethane holds up to Altadena's heat and cold swings better than standard roofing cement.
Pry bar and roofing hammer
Lifts shingle edges and sets nails without tearing the surrounding roof. This keeps the repair small and preserves the shingles around the flashing.
Seam roller
Presses butyl tape and metal seams together for a watertight bond. It is the step that turns two pieces of flashing into one continuous barrier.
Measuring tape and utility knife
Measures the joint and trims membrane or tape to fit. Accurate measurements mean fewer seams and less chance of a future leak.
Methods & Techniques
Two-layer flashing system
We install step flashing under the shingles and counter flashing over the top, so water has to defeat two separate barriers. This is the standard NRCA member approach and it is what we use on every chimney and wall repair.
Butyl tape and roofing cement bedding
New flashing gets bedded in butyl tape and roofing cement before it is fastened. The tape seals around nail heads and the cement fills gaps between the metal and the roof deck.
Polyurethane sealant finishing
Every exposed flashing edge gets a bead of polyurethane sealant. It stays flexible through Altadena's freeze-thaw cycles, unlike the brittle sealant we routinely cut out.
Water test verification
We run water over the repaired joint and watch from the attic before we call the job done. If a drop gets through, we find it and fix it on the spot.
How Storm Damage Flashing Repair Runs in Altadena
Altadena's position against the San Gabriel Mountains shapes every flashing repair we do. Winter storms push rain sideways into roof joints, and the wind that comes through Rubio Canyon and Winter Creek can lift flashing that looked fine in October. The freeze-thaw cycle in January and February cracks old sealant, which is why we see a spike in storm damage flashing repair near me in Altadena CA calls every December through March. Most of the housing stock here was built between 1920 and 1970, so we work with original galvanized steel, copper, and lead flashing that needs matching metal, not a modern substitute. Los Angeles County building rules require specific lap and clearance standards on counter flashing and kickout flashing, and we build to those standards on every job. Homes in the 91001 and 91003 ZIP codes near the foothills get the worst wind exposure, while 91104 properties closer to Altadena Town Center deal more with chimney flashing leaks from aging mortar. If you have storm damage flashing leak repair in Altadena, California on your list, we can usually get to it within a day.
Service Areas
Older bungalows with original chimney flashing and narrow roof-to-wall clearances. Wind exposure here is moderate, but aging mortar joints are a common leak source.
Foothill properties that take the full force of winter wind. Step flashing and kickout flashing failures are common after December storms.
Historic homes where flashing repairs have to match original profiles. We fabricate custom pieces on site so the repair blends with the existing roof.
A mix of older homes and newer builds. Chimney flashing and skylight curb leaks are the most frequent calls we get from this area.
Higher elevation means more freeze-thaw cycles. Sealant cracks faster here, so we use polyurethane and check the joint again each fall.
Local Considerations
Wind-driven rain from the San Gabriel Mountains
Rain pushes sideways under lifted flashing, so the leak shows up on a wall or ceiling far from the actual gap. We test joints with water to find the real entry point.
Freeze-thaw cycles in January and February
Water gets into a sealant crack, freezes, and widens it. By spring the joint is wide open. Polyurethane sealant stays flexible through these swings.
Aging galvanized steel on pre-1970 homes
Original flashing rusts through after decades of exposure. We replace it with copper or new galvanized steel that matches the roof's remaining life.
Los Angeles County flashing code requirements
Counter flashing and kickout flashing have to meet specific lap and clearance standards. We build to code so the repair passes inspection the first time.
Chimney Flashing Leak in West Altadena
A 1948 bungalow had water staining on the ceiling below the chimney after a December storm. The original galvanized counter flashing had rusted through, and the mortar joint was cracked. The homeowner had a bucket in the living room and was worried about the ceiling caving in.
We replaced the counter flashing with copper, rebuilt the step flashing, and resealed the mortar joint. The water test ran dry, and the ceiling stain stopped spreading. The repair cost $520 and took four hours.
Maintenance & Follow-up
Check the chimney flashing each fall before the rainy season. A quick look at the mortar joint and the metal edges catches most problems before they leak.
A 1990s home had a cracked vent pipe boot that leaked into the attic during the first fall rain. The boot was brittle from UV exposure, and the surrounding shingles were stained. The homeowner noticed a musty smell in the hallway.
We replaced the boot with an EPDM unit, resealed the base, and checked the attic for wet insulation. The leak stopped, and the musty smell cleared once the attic dried out. The job took under two hours and cost $240.
Maintenance & Follow-up
Inspect vent boots every two years. UV breaks down rubber over time, and a $240 replacement beats a $2,000 insulation job.
A two-story home on a foothill lot had wind-driven rain pushing under the step flashing along a second-story wall. The drywall inside was soft, and the paint was bubbling. The homeowner had already called two other companies who wanted to replace the whole roof.
We replaced the step flashing with new copper, added a kickout flashing at the bottom of the run, and sealed the wall joint. The wall dried out, and the paint stopped bubbling. The repair cost $680 and took five hours.
Maintenance & Follow-up
Keep the kickout flashing clear of debris. If you see water running down the wall during a storm, call us before the siding rots.
