Gutter & Roof Drainage Repair in California keeps rain off your fascia, out of your walls, and away from your foundation. We clear clogs, reseal joints, re-pitch sagging runs, and replace crushed downspouts from the coast to the Central Valley. If water is sheeting off your roof or pooling at the base of your house, we can be on site the same day.
Gutter & Roof Drainage Repair in California means restoring the entire path water takes off your roof: the gutter run, the hangers, the seams, the end caps, the downspouts, and the splash blocks or underground drains at the bottom. We pull packed debris, re-pitch runs that have sagged, seal open seams with roof cement and gutter sealant, and replace rusted steel or cracked vinyl with aluminum or copper that matches your home. Every joint gets tested with water before we pack up.
California homes take a specific beating. Long dry months bake sealant until it cracks, then the first atmospheric river dumps two inches in a day and every weak seam lets go. We see gutter overflowing roof damage in Berkeley hillside homes, salt-corroded downspouts in Daly City, and pine-needle clogs in Santa Cruz that back water under shingles. If you have been searching for clogged gutter repair near me California, that pattern is exactly what we fix.
Every job starts with a full inspection of the drainage path and ends with a water test. The list below covers what we handle on a standard repair. Roof deck repairs, interior drywall, and full gutter replacement are separate scopes we quote only if the inspection shows they are needed.
We walk the entire run with a ladder and safety harness, checking hanger spacing, pitch, seam condition, and downspout flow. Moisture meter readings on the fascia and infrared scans on interior ceilings confirm whether water has already reached the structure.
Leaves, pine needles, shingle grit, and tennis balls come out by hand, then we flush the run and each downspout with a hose. If the underground drain is blocked, we snake it and confirm flow at the discharge point.
Sagging runs get re-pitched to a minimum quarter-inch per ten feet and re-hung with new hangers spaced no more than 36 inches apart. That is the single biggest fix for standing water and overflow at the low end of the run.
Open seams, end caps, and outlet joints get cleaned, primed, and sealed with roof cement and gutter sealant rated for UV exposure. We do not caulk over wet or dirty metal, because that seal fails within one season.
Crushed, separated, or corroded downspouts get repaired or replaced in matching material. We add extensions and splash blocks to move discharge 4 to 6 feet from the foundation, which is where most damp crawlspace problems start.
We run water through the whole system and watch every joint and outlet. You see the flow at the discharge point, we point out what was fixed, and you get written notes on what to check before the next rainy season.
You call (877) 299-0450 and describe what you are seeing: water over the front edge, a stain on the ceiling, a downspout that drips at the joint. We ask three or four questions to figure out whether this is a gutter issue, a flashing issue, or a roof leak, and we schedule a same-day or next-morning visit.
A technician walks the roofline with a ladder and safety harness, checks hanger spacing, pitch, seam condition, and downspout flow. We use a moisture meter on the fascia and an infrared camera on interior ceilings when there is a stain. Expect 30 to 45 minutes on a typical single-story home.
You get the findings in plain language: what is failing, what it costs to fix, and what can wait. No pressure, no upsell on services you do not need. Most homeowners approve on the spot because the numbers are clear and the scope is specific.
We clear the run, re-pitch sagging sections, replace failed hangers, seal seams with roof cement and gutter sealant, and rebuild or replace damaged downspouts. A standard 150-foot run takes two to four hours with a two-person crew.
Before we leave, we run water through the entire system and watch every joint. You see the flow at the discharge point, we point out what we fixed, and you get a written summary of the work plus maintenance notes for the next rainy season.

Every roof access uses a stabilizer-equipped ladder and an OSHA-compliant harness. That is how we work safely on two-story homes and steep-pitch roofs without risking a fall.
We take readings on fascia boards, soffits, and interior ceilings to confirm whether water has reached the structure. It tells us the difference between a cosmetic stain and an active leak.
Thermal imaging shows us where water is traveling behind the surface. It is how we trace a ceiling stain back to the actual entry point instead of guessing.
We clean and prime every joint before sealing with UV-rated gutter sealant and roof cement. Skipping the prep is why most homeowner caulk jobs fail within one season.
Used to lift shingle edges, open failed seams, and trim damaged underlayment or flashing so the repair sits flat and seals properly.
When a repair involves re-securing shingles or underlayment at the eave, we set fasteners with a roofing nail gun so the roof edge stays tight above the gutter line.
A 140-foot front gutter had pulled away from the fascia and held standing water across the middle 40 feet. The low end overflowed every storm, staining the siding and soaking the foundation bed.
After: We replaced 11 failed hangers, re-pitched the run to a quarter-inch per ten feet, and sealed four open seams. Water test showed full flow to the downspout in under 20 seconds with no standing water remaining.

The ocean-side downspout had rusted through at the elbow and separated from the gutter outlet. Every storm sent water straight down the exterior wall and into the soil at the foundation.
After: We replaced the downspout in heavier-gauge aluminum, re-seated the outlet fitting, and extended discharge 6 feet from the wall. The wall dried out over the following weeks and the foundation bed stopped pooling.

First storm of the season sent water over the front gutter onto the porch. The run held about three inches of packed leaf debris, and the seam at the inside corner had cracked open over the summer.
After: We cleared the full run, flushed both downspouts, and re-sealed the corner seam with roof cement and gutter sealant. Total job time was under two hours, and the water test showed clean flow at both discharge points.
Book this service →Most drainage complaints fall into a handful of patterns. Here are the ones we see most often across California, what happens if you leave them alone, and how we fix them.
Ask a pro →We clear the blockage, re-pitch the run, and verify the downspouts can handle the flow. If the run is undersized for the roof area, we add a second downspout so the system keeps up with atmospheric river rainfall.
We re-seat the downspout, replace the outlet fitting if it is cracked, and seal the connection with gutter sealant. Then we extend the discharge away from the wall and re-grade the splash path.
We re-pitch the run to a minimum quarter-inch per ten feet and replace failed hangers with new ones spaced no more than 36 inches apart. Standing water drains fully, and the run stops pulling away from the fascia.
We trace the water with a moisture meter and infrared camera, then repair the actual entry point, whether that is a failed gutter seam, a lifted shingle, or a flashing detail. The drainage and the roof edge get fixed together.
Most residential repairs run $250 to $900 in 2026, with a typical single-run fix around $400. Simple re-sealing of two or three joints lands near the low end. Full replacement of a 150-foot run with new hangers and downspouts pushes toward the top. Emergency after-hours calls and two-story access add cost. We quote the whole scope before starting, so the invoice matches the number you approved.
Clear the debris by hand, flush the run with a hose, and check that water exits the downspout within a few seconds. If it backs up, the clog is in the downspout elbow or the underground drain. We use a ladder, safety harness, and a plumber's snake on stubborn blockages, then water-test the whole system. Pine needles in Santa Cruz and Modesto need twice-a-year clearing; most other areas do fine once a year in October.
The three most common causes are failed seam sealant, a sagging run that holds standing water, and a downspout that has separated from the gutter outlet. UV exposure dries out sealant over summer, then the first storm finds every crack. We inspect the full path with a moisture meter and infrared camera, then repair the actual failure point instead of just caulking over it.
Yes. A backed-up gutter pushes water under the bottom shingle course and into the roofing underlayment, which is how many so-called roof leaks start. Clearing the run, re-pitching it, and sealing the seams keeps the roof edge dry. If we find damaged underlayment or flashing during the repair, we fix that on the same visit so the drainage and the roof edge work together.
Our crews cover gutter and roof drainage repair across California, from the coast to the Central Valley to the Inland Empire. Whether you need storm gutter repair before the next system or a full re-pitch after years of standing water, we dispatch from the nearest available crew and get a technician on your roof.
Santa Clarita homes sit in a wind corridor that pulls gutters loose at the hangers. We re-secure runs, replace failed hangers, and re-pitch to handle the debris load from surrounding oak and sycamore.
↗ 02 InglewoodInglewood has a mix of older homes with original steel gutters and newer builds with undersized downspouts. We repair both, and we extend discharge away from the foundation on the flat lots common here.
↗ 03 Culver CityCulver City homes often have tight side-yard access, so we plan ladder placement and equipment staging before we arrive. Most repairs finish in a single visit with a full water test at the end.
↗ 04 Huntington BeachSalt air corrodes steel hangers and downspout fasteners fast in Huntington Beach. We spec corrosion-resistant hardware and heavier-gauge aluminum, and we check the flashing while we are on the roof.
↗ 05 Newport BeachNewport Beach roofs often have complex runs and multiple downspouts. We re-pitch each section, verify flow at every discharge point, and repair the seams that UV exposure has opened over summer.
↗ 06 Aliso ViejoAliso Viejo tract homes typically have long front runs that sag at the middle. We re-pitch to a quarter-inch per ten feet, replace failed hangers, and add a second downspout when the roof area demands it.
↗ 07 VistaVista sits in a marine layer zone that keeps gutters damp and promotes algae growth. We clear the run, flush the downspouts, and seal the joints with UV-rated gutter sealant that holds through the dry season.
↗ 08 FontanaFontana summer heat bakes sealant until it cracks. We re-seal every joint with UV-rated roof cement and gutter sealant, then re-pitch runs that have warped under the inland heat.
↗ 09 RedlandsRedlands has a lot of mature trees and clay tile roofs. Pine needles and leaf debris pack the downspout outlets, so we clear the full run and verify flow before the first storm of the season.
