The Brothers That Just Do Gutters · San Ramon
El Niño gutter prep for San Ramon and the Tri-Valley, before the first storm.
NOAA puts the odds of a strong to very strong El Niño this winter above 83%. The last one this size, in 1997-98, put 25.52 inches on the Livermore gauge, and 7.30 of it fell in February alone. El Niño pulls harder on Southern California than on the Bay Area, so here it raises the odds of a wet winter rather than promising one. Either way, your gutters are the first thing standing between the rain and your roofline, fascia, foundation and hillside. We clean them, repair them and storm-test them before the first Pacific system hits.

Quick answer
El Niño Gutter Preparation in San Ramon and the Tri-Valley, CA: NOAA issued an El Niño Advisory on September 10, 2026 and forecasts the strongest El Niño since 1997-98 for this winter. In the Bay Area that raises the odds of a wet winter without guaranteeing one. The Brothers That Just Do Gutters San Ramon gets homes storm-ready with full cleanings, downspout flushing, seam sealing, slope and outlet corrections, added downspouts where one drop cannot keep up, drainage extended away from the foundation, and BroGuard metal mesh guards so debris does not rebuild between storms. Estimates are free. Call (925) 905-9555 or book online.
By the numbers
This is not a normal rainy season. The forecast says record territory.
NOAA’s Climate Prediction Center issued an El Niño Advisory on September 10, 2026, and its October 8 update says the event is still strengthening. The National Weather Service is plain that El Niño’s link to Northern California rain is much weaker than in Southern California, so treat these as better odds, not a promise. The numbers below are NOAA’s, not ours.
- 90%+chance of a very strong El Niño this fall and winter, per NOAA’s September 10, 2026 discussion
- 83%chance October to December 2026 becomes the strongest El Niño on record since 1950, per NOAA’s October 8 update
- 25.52inof rain at the Livermore gauge in the 1997-98 El Niño season, against a normal year of 14.60
- 31.95infell at Livermore in the 1982-83 El Niño season, more than twice a normal year

What the last big one did
Same pattern as 1997-98. The ocean says this one could be stronger.
In the winter of 1997-98 El Niño storms caused over $150 million in landslide damage across the ten Bay Area counties, and on February 9, 1998 all ten were declared eligible for federal disaster aid. Contra Costa County alone logged at least 119 damaging landslides and about $27 million in damage, most of it in the built-up western and northern parts of the county. In Orinda a mudslide threw three houses off their foundations. The Livermore gauge caught 25.52 inches that season and the Mount Diablo Junction gauge caught 44.60, with February the wettest month at both. A stronger El Niño does not promise more Tri-Valley rain, but it does tilt the odds. The photos below show what a season like that looks like on the ground in California, and every one of them started with water that had nowhere to go.
Get storm-ready nowWhat it does to a Tri-Valley house
A super El Niño finds every weak point on your roofline.
Gutters are not decoration. They are the drainage system for your roof, and in a season like this one they are the difference between water going where you want it and water going everywhere else.
- 01
Overflow at the fascia
A clogged or under-pitched gutter sheets water over the back edge, straight into the fascia board and the roof sheathing. One wet winter is enough to rot both.
- 02
Water at the foundation
Downspouts that dump at the base of the house soak the soil right against the slab. Tri-Valley clay holds that water instead of draining it, so it sits against the foundation for weeks. That is how garages flood and slabs crack in a wet year.
- 03
Saturated hillsides
Hillside homes need roof water carried to a controlled drain, not released onto the slope. In 1997-98 Contra Costa County logged at least 119 damaging landslides, and failed fill made the damage worse at many of them.
- 04
Debris that rebuilds between storms
Oak leaves, eucalyptus bark and pine needles refill an open gutter in weeks. In a back-to-back storm pattern there is no window to clean between systems. Metal mesh guards keep the trough clear all season.
The pre-storm visit
Storm-ready in one visit, before the wet months.
A Solutionist walks the whole roofline, then the crew does the work the same day whenever possible. You get a written report of what was cleaned, what was fixed and what we recommend before the first big system.

- Add downspouts where one cannot keep upLong roof sections draining to a single drop get a second outlet so they do not overflow in a downpour.
- Move water away from the houseExtensions, splash blocks or underground drainage so roof water leaves the foundation, the clay against the slab and the slope.

Official guidance
The state and Contra Costa County point to the same first step: the gutters.
Governor Newsom declared a statewide state of emergency on September 21, 2026 to get California ready for El Niño. The forecasters are honest that the Bay Area signal is weaker and less reliable than Southern California’s, but the advice for homeowners is the same everywhere, and it starts at the roofline.
State of California, Sept 21, 2026
“Clear drains and gutters”
The Governor’s emergency release tells homeowners to know their flood risk, clear drains and gutters, sign up for alerts and make a plan before severe weather arrives.
Contra Costa County
“Clean gutters.”
That is the first line of the County’s winter storm checklist, followed by clearing leaves off nearby storm drains and keeping the pipes and ditches on your property open.
National Weather Service Sacramento
No sure thing up here
“In Northern California, there is little correlation between precipitation and most ENSO patterns,” and a wet winter “is not a certain outcome.” That is why we prep for the storms, not the headline.
NOAA Climate Prediction Center, Sept 17, 2026
Better odds, no promise
NOAA’s winter outlook tilts California toward a wetter than normal season, with the odds peaking at 50 to 60 percent near the coast, and says El Niño impacts are “not guaranteed.”

Checklist
Your El Niño gutter checklist for San Ramon and the Tri-Valley
This is the same list our crews work through on every pre-storm visit. Do what you can yourself, and call us for anything that needs a ladder.
- Clear every gutter by handOak leaves, eucalyptus bark and pine needles that sat all summer turn into sludge in the first storm and hold water against the fascia.
- Flush and test every downspoutA downspout packed at the elbow backs water up into the gutter and over the front edge, usually right above a door or window.
- Check pitch, hangers and seamsWater still standing after a flush means a sagging run or a loose hanger. Drips at the corners mean a failed seam.
- Size up the valleysWhere two roof planes meet, water arrives faster than a 5-inch gutter can carry in a big storm. A 6-inch gutter or an added downspout fixes it.
- Move the water away from the houseSend every downspout at least 5 feet out with an extension, splash block or underground line, so roof water stays off the foundation and away from the slab.
- Mind the clayTri-Valley clay soil holds water instead of draining it. A downspout that empties at the slab keeps that soil soaked all winter, so send it to landscaping or a drain line well away from the house.
- Protect the troughBroGuard stainless micro-mesh keeps debris out between cleanings, so the gutter is open when a storm peaks in the middle of the night.
- Finish before the wet monthsAt Livermore about 82% of a normal year’s rain falls from November through March, per NOAA’s 1991-2020 normals. Our schedule fills once the forecast turns, so get on it in October.

Hillside and canyon homes
On a slope, the gutter decides where the water lands.
East Bay hillsides have moved in wet winters before. In 1997-98 Contra Costa County logged at least 119 damaging landslides, six houses and two small apartment buildings were red-tagged in its unincorporated areas, and failed fill added to the damage at many sites. In Orinda a mudslide threw three houses off their foundations. In Alameda County, the U.S. Geological Survey mapped heavy debris-flow activity around Walpert Ridge above Highway 680 and in the canyons northeast of Castro Valley. Gutters cannot hold a hillside together, but they control where your roof water goes. A downspout that dumps at a corner cuts a channel under the foundation and adds water to the slope. We route every downspout to a safe outlet, add downspouts where a long run needs them and make sure nothing drains toward the slope.

Frequently Asked Questions
NOAA forecasts a very strong El Niño this winter, likely the strongest since 1997-98. Its Climate Prediction Center has an El Niño Advisory in place, and its October 8 update gives a greater than 83 percent chance of a strong to very strong El Niño through January to March 2027 and an 83 percent chance that October to December becomes the strongest El Niño on record since 1950. For the Bay Area that raises the odds of a wet winter, but El Niño’s pull on rain here is weaker and less reliable than in Southern California.
The Livermore gauge recorded 25.52 inches in the 1997-98 season, about 75% more than its normal year of 14.60 inches, and 7.30 inches of that fell in February 1998, according to NOAA station records. Up on Mount Diablo, the Mount Diablo Junction gauge caught 44.60 inches against a normal 26.05. The 1982-83 El Niño was wetter still at Livermore, with 31.95 inches.
Start with a full cleaning and a flush of every downspout, then fix what the water will find: leaking seams and end caps, sagging runs with the wrong slope, and long roof sections draining to a single downspout. Carry the water away from the foundation with extensions or underground drainage, and add BroGuard mesh so debris does not rebuild between storms.
In October or early November, before the first big storm. At Livermore about 82% of a normal year’s rain falls from November through March. A Solutionist walks the roofline, and the crew does the work the same day whenever possible, with a written report of what was cleaned, fixed and still recommended. Call (925) 905-9555 early.
Because roof water released onto a slope adds to ground that is already saturated. In 1997-98 Contra Costa County logged at least 119 damaging landslides and about $27 million in damage, and in Orinda a mudslide threw three houses off their foundations. Where your downspouts end matters as much as the gutter itself.
Yes, fast. Oak leaves, eucalyptus bark and pine needles can refill an open gutter within weeks, and in a back-to-back storm pattern there is no dry window to get up and clean between systems. Stainless BroGuard micro-mesh keeps the trough clear all season, so the gutter you paid to clean in October still works in February.
NOAA’s October 8, 2026 update keeps an El Niño Advisory in effect and gives a greater than 83% chance of a strong to very strong El Niño through January to March 2027. In the Bay Area that raises the odds of a wet winter but does not guarantee one. The National Weather Service notes there is little correlation between most El Niño patterns and Northern California rain, and in the strong 2015-16 El Niño Livermore got 15.41 inches, close to a normal year. Have the gutters ready either way.
About 14.60 inches at the Livermore gauge, based on NOAA’s 1991-2020 normals, and about 82% of it falls from November through March. The hills get far more: the Mount Diablo Junction gauge averages 26.05 inches. In 1997-98 Livermore got 25.52 inches, and in 1982-83 it got 31.95.
Now through early November, before the first big storm. At Livermore December, January and February each average more than 2.7 inches, the wettest stretch of the year, and our schedule fills up once the forecast turns.
The U.S. Geological Survey counted over $150 million in landslide damage across the ten Bay Area counties, all of which were declared eligible for federal disaster aid on February 9, 1998. Contra Costa County had at least 119 damaging landslides and about $27 million in damage, and Alameda County about $20 million. On February 10 a cutslope failure above Wildcat Creek Road in Richmond affected access to about 25 homes, and in Orinda a mudslide threw three houses off their foundations.
The Governor’s September 21, 2026 emergency release tells homeowners to clear drains and gutters, sign up for alerts and make a plan. Contra Costa County’s winter storm checklist starts with “Clean gutters.” Your gutters are the first drain your roof water reaches, so cleaning them, flushing the downspouts and fixing leaks and sags before the wet months covers the part of that list that sits on your house.
Yes, if they are the right kind. BroGuard stainless micro-mesh keeps leaves and roof grit out while heavy rain passes straight through, so the gutter is open when a storm peaks. Foam inserts and plastic screens can clog or warp.
