The Brothers That Just Do Gutters · the East Bay

Gutter fire hardening for San Ramon and the East Bay, before the next Diablo wind.

When a grass or oak-woodland fire runs the Diablo foothills, the flame front is rarely what threatens a house in Windemere, Blackhawk or the Lafayette hills. Embers are. They ride the offshore wind, land by the thousand and look for somewhere dry to sit. A gutter full of oak leaves and pine needles is exactly that. We replace vinyl with metal, cover the trough with non-combustible BroGuard mesh and clean before fire season, so there is nothing up there to catch.

Quick answer

Fire hardening in the East Bay, CA: The Brothers That Just Do Gutters harden the roofline where embers actually land. Metal gutters formed on site, BroGuard non-combustible stainless mesh over the trough so dry debris cannot collect, screened downspouts, closed fascia gaps and cleanings timed to the local fire season. California’s Wildland-Urban Interface Code, Section 504.4 (formerly Chapter 7A), requires gutters in wildfire areas to have a means to keep leaves and debris from accumulating, and the State Fire Marshal’s updated Fire Hazard Severity Zone maps, released February 24, 2025, put parts of San Ramon in Moderate and High zones. Estimates are free. Call (925) 905-9555 or book online.

By the numbers

The Bay Area has already seen what a wind-driven fire does. The maps say it can happen here.

These are the state’s and the county’s own numbers, not ours.

What wind-driven fire looks like here

Same Diablo wind as Oakland in 1991. Same fuel on the roofline today.

The offshore Diablo wind that drove the 1991 Oakland Hills firestorm is the same pattern behind the 2017 Tubbs Fire that erased Coffey Park in Santa Rosa, the 2019 Kincade Fire in Sonoma County, and the 2020 lightning complexes that burned across the Diablo Range and the Santa Cruz Mountains. In every one of them, homes were lost to embers landing on dry rooflines far ahead of the flame front. The photos below are from those Bay Area fires, and the gutter is where the embers land first.

Where the risk sits today

San Ramon is a mapped city now. So are the hills around it.

The State Fire Marshal’s updated Fire Hazard Severity Zone maps, released February 24, 2025, put parts of San Ramon in Moderate and High zones, and the Tri-Valley hills from Danville and Alamo through Blackhawk, Diablo and the Tassajara Valley to Orinda, Lafayette and Walnut Creek sit against open grass and oak woodland. If your address sits near open hillside, the roof edge is the part of the house doing the most work.

  • 01

    Embers in the trough

    A gutter holding a summer of oak leaves, pine needles and roof grit is kindling pressed against the fascia. On a Diablo wind that is how a house well ahead of the fire catches.

  • 02

    Plastic on the roofline

    Vinyl gutters and plastic guards soften, drop and burn. The state wildfire code (Section 504.4, formerly Chapter 7A) calls for gutters that keep debris out, and fire agencies call for noncombustible material at the roof edge.

  • 03

    Open downspout tops and gaps at the fascia

    An open downspout top lets embers fall right into the gutter system. A gap along the fascia lets them creep beneath the first row of roofing.

  • 04

    Zone 0 is coming

    On August 19, 2026, the state Board of Forestry approved Zone 0 rules covering Very High zones and State Responsibility Areas. On September 8, 2026 they were withdrawn from state review for technical changes, so they are not yet in effect. Keeping roofs and gutters free of combustible debris is part of those rules.

The hardening visit

A fire-hardened roofline, done before the offshore wind sets up.

First, a Solutionist checks your entire roofline and gives you a scope and price in writing. Then the crew does the work, most often that same day. You receive a report on what was cleared, what was swapped out and what we suggest before the next Red Flag Warning.

The rules in 2026

What state wildfire rules in California really require of gutters

Much of what East Bay homeowners hear about fire rules is outdated. Here is the status for gutters as of September 2026, with a source for each point.

State building code

Gutters must keep debris out

Since January 1, 2026, California’s wildfire construction rules live in the new California Wildland-Urban Interface Code. Section 504.4 keeps the old Chapter 7A wording: roof gutters must have a means to prevent leaves and debris from building up. It applies to new construction and permitted alterations in mapped fire hazard areas.

Your fire district

State law already covers the roof

California already requires homeowners in fire hazard areas to keep the roof free of leaves, needles and other plant material (Gov. Code 51182), and the San Ramon Valley Fire Protection District sends yearly abatement notices to wildland-urban interface owners.

Zone 0, the five feet closest to the house

Approved, then withdrawn for revisions

On August 19, 2026, the Board of Forestry approved Zone 0 rules that include keeping roofs and rain gutters free of small flammable material. On September 8, 2026 the package was withdrawn from state review for technical changes, so it is not in effect yet. Once it is, it will apply to Very High zones inside cities and to every state responsibility area.

IBHS Wildfire Prepared Home

Metal gutters first, metal guards next

The insurance industry’s wildfire standard calls for noncombustible gutters and downspouts and regular debris removal at its base tier, then adds noncombustible gutter guards at the Plus tier. Metal gutters topped with BroGuard stainless mesh meet both.

Insurance discounts

Gutters are missing from the state discount list, but they still count

The state’s Safer from Wildfires discount list rewards Class A roofs, vents that resist embers, upgraded windows, enclosed eaves and the five-foot zone, and leaves gutters off. Fire agencies keep bringing up gutters because of embers: IBHS research found embers were the first ignition source for up to 90 percent of homes that wildfires damaged or destroyed, and a gutter packed with dry oak leaves is where they settle.

Fire hazard zones

Which East Bay and Tri-Valley cities have Very High zones?

The State Fire Marshal released new local fire hazard maps for Contra Costa, Alameda and San Joaquin counties on February 24, 2025. These are the Very High acres mapped inside city limits in our territory. The state also maps the wildland around them separately.

CityVery High acres (2025)

Antioch858
Berkeley454
El Cerrito329
Concord79
Brentwood75
San Pablo58
Lafayette (down from 4,440 in 2011)41

What about San Ramon?

San Ramon has no Very High zone inside city limits. Its 2025 map shows 1,493 High and 4,029 Moderate acres. Walnut Creek, Pleasant Hill, Martinez and Pittsburg also have no Very High zone. Tracy is mapped Moderate and High only, and Stockton and Manteca have no mapped zones.

Checklist

The ember-ready roofline checklist

Our crews follow this sequence on every fire-hardening visit in the Tri-Valley. You can handle steps one and seven on your own. For anything that needs a ladder, give us a call.

  1. Clean off the roof and each gutterHomes in fire hazard areas are already required by state law to keep roofs clear of leaves and needles. Begin there, then flush each downspout.
  2. Trade vinyl for metalIBHS calls for noncombustible gutters and downspouts. We roll out aluminum, bonderized steel or copper right at your home, so nothing at the roof edge can melt or catch.
  3. Top the gutter with a metal guardA noncombustible guard such as BroGuard stainless micro-mesh keeps dry oak leaves out between cleanings, which is the IBHS Plus step and something CAL FIRE recommends.
  4. Seal the gap at the roof edgeResearch the Board of Forestry cited showed gutter debris can pull fire into a home at the joint between roof and gutter. Drip edge and a snug fit seal it.
  5. Clean out valleys, dormers and cornersAccording to IBHS, the places where debris gathers on a roof are the same places embers collect.
  6. Keep the area below the gutters clearReplace bark mulch and plantings under downspouts with gravel or hardscape, which counts toward the ember-resistant five-foot zone on the state’s discount list.
  7. Trim what hangs over the roofOverhanging oak and bay limbs drop exactly the fine litter embers catch in.
  8. Book it before Diablo wind seasonSchedule the work in late summer or early fall, before the dry offshore winds that drive ember storms.

Where this comes from: Government Code 51182, the IBHS Wildfire Prepared Home checklist, CAL FIRE home hardening, the Board of Forestry, the Office of Administrative Law, the California Department of Insurance.

Frequently Asked Questions

How do embers set a house on fire through the gutters?

Embers hit the roof edge before anything else. A gutter filled with dry oak leaves, needles and roof grit is tinder pressed up against the fascia and decking, and IBHS research found embers, not the flames themselves, were the first ignition source for up to 90 percent of homes that wildfires damaged or destroyed.

What happens during a gutter fire hardening visit?

We clean and flush the entire system, swap vinyl or worn-out runs for metal gutters rolled out on-site, put on BroGuard stainless micro-mesh, seal the gaps along the roof edge and at the downspouts, and show you anything else along the roofline worth fixing before fire season.

Are California’s Zone 0 rules in effect yet?

Not at this point. On August 19, 2026, the Board of Forestry approved Zone 0 rules covering the first five feet around a home, but on September 8, 2026 the package was withdrawn from state review for technical changes. State law already has homes in fire hazard areas keep roofs clear of leaves and needles, and the approved rules carry that over to rain gutters.

What does California’s building code say about gutters in fire zones?

Since January 1, 2026, the rule is Section 504.4 of the California Wildland-Urban Interface Code, which replaced Chapter 7A and R337. Roof gutters must have a means to prevent leaves and debris from building up. The state text does not name a material, but the IBHS Wildfire Prepared Home standard calls for noncombustible gutters and downspouts.

Do gutter guards lower home insurance in California?

The state’s Safer from Wildfires discount list leaves out gutter guards; it rewards roofs, eaves, vents, windows and that five-foot zone. The IBHS Wildfire Prepared Home standard, though, requires noncombustible gutters, then adds noncombustible guards at its Plus tier, so check with your insurer on how they handle that designation.

Are vinyl gutters and plastic guards a fire risk?

Yes. Plastic or foam guards and vinyl gutters can soften, melt or catch fire when embers drop into them, and a melted gutter leaves debris and embers resting against the fascia. Metal gutters topped with stainless mesh leave embers nothing to ignite.

Does San Ramon have a Very High fire hazard zone?

No. The State Fire Marshal’s February 24, 2025 map for San Ramon shows 1,493 High and 4,029 Moderate acres and no Very High zone inside city limits. Nearby, Orinda has 5,241 Very High acres, Clayton 1,302 and Danville 29.

Which East Bay cities have the most Very High fire zone land?

In our territory, Orinda (5,241 acres), Richmond (4,395), Clayton (1,302), Antioch (858) and Berkeley (454) have the most Very High acres inside city limits on the 2025 state maps.
