When a winter storm drops a redwood across your driveway, a fire-weakened oak fails in your yard, or a limb is hanging over the bedroom, you need a crew that moves now. Our emergency teams answer 24 hours a day, 7 days a week, including weekends and holidays, throughout Santa Rosa, Healdsburg, Petaluma, Sebastopol, Windsor, Kenwood, and Guerneville.
We arrive ready to handle hazardous removals safely and quickly. We document damage for insurance, clear access, and eliminate the hazard completely before we leave.
Dead trees, drought-stressed trees, fire-damaged trees, structurally compromised trees, and trees that have simply outgrown the space. We handle all of them. Every job starts before the first cut: full site assessment, risk identification, removal sequencing, and precise execution.
Our specialized equipment, including cranes, bucket trucks, and advanced rigging, lets us work in tight Santa Rosa neighborhoods, near hillside structures, close to power lines, and on the steep rural lots common across Sonoma County. Crane-assisted hazardous tree removals are a specialty, not an exception.
Tree trimming keeps your canopy in shape and pulls branches back from where they cause problems. Roofs, gutters, power lines, driveways, and walkways. It also clears out the deadwood that becomes a hazard the next time the wind picks up.
On Sonoma County properties, regular trimming does double duty. It opens sightlines, lets more light through, and cuts down on fire fuel sitting close to your home. Our crews work to a plan: identify the problem limbs, clear what needs clearing, shape the canopy without over-cutting.
Pruning isn't the same as trimming. It's a health and structure call, and done right, it's one of the best things you can do for a tree long term. The point is to remove structural weaknesses before they fail in a winter storm, improve how the tree carries its weight, and encourage healthy growth through our long Sonoma County season.
Wrong cuts do more damage than no cuts at all, so timing, technique, and knowing the species matter. Our arborist-informed approach targets the specific branches and growth patterns putting your tree, or your property, at risk. We take what needs to go and leave the rest alone.
Preparing land for new construction, expanding a building envelope, reclaiming an overgrown rural lot, or clearing brush after a wet winter. We have the equipment to handle it efficiently. Projects from a single overgrown Santa Rosa lot to multi-acre rural clearing in the hills around Healdsburg and Kenwood.
We protect adjacent structures, fencing, and any vegetation you want preserved, and we haul all debris so the site is ready for what's next.
This is Sonoma County. Fire abatement isn't a side service for us. It's a core part of what we do. We help homeowners, ranches, and commercial properties meet California's defensible-space requirements (Zone 0, Zone 1, and Zone 2) under PRC 4291, reduce ladder fuels, remove fire-prone vegetation near structures, and harden the property against the next red-flag event.
We work with insurance inspections, Cal Fire requirements, and local fire district guidance, and we can pull permits when the project calls for them.
Empire Tree Experts is a family-owned, locally operated tree service based in Santa Rosa, California. Sixty years in business and over a hundred years of combined team experience have taught us a simple lesson: show up on time, bring the right equipment, do the work properly, and leave the property in better shape than you found it. That hasn’t changed across six decades, and it isn’t going to.
We’re not a franchise and we’re not a call center routing your job out to whoever picks up. When you call Empire Tree Experts, you’re talking to the people who will run the equipment, climb the tree, and stand behind the result.
We serve homeowners, commercial property owners, vineyards, and municipal clients throughout Santa Rosa, Healdsburg, Petaluma, Sebastopol, Windsor, Kenwood, and Guerneville.
Empire Tree Experts serves residential, commercial, and rural clients throughout Sonoma County. If you're not sure we cover your area, call and ask. We likely do.
Sonoma County Communities We Serve
Tree removal, major trimming, and significant landscaping work in Santa Rosa and across Sonoma County may be subject to local ordinances, especially for heritage trees, oaks, riparian buffers, and trees near public rights-of-way. Defensible-space and fire abatement work has its own set of state and local requirements. Verify before proceeding.
Municipal tree protection ordinance, heritage tree designations, and removal permit requirements within Santa Rosa city limits.
Tree removal permits, zoning, and use-permit guidance for unincorporated Sonoma County.
California state requirements for defensible space around homes in fire-prone areas, including Zone 0, Zone 1, and Zone 2 guidance.
Professional arborist standards, tree care education, and certification verification.
Industry safety standards, accreditation, and best practices for professional tree service operations.
Storm warnings, wind advisories, and red-flag fire weather alerts affecting tree safety across Sonoma County.
Not sure whether your project needs a permit? Call us. We’ve worked through the local requirements across Sonoma County for decades and can point you in the right direction. Permitting services available.
Storm damage, fire damage, and hazardous tree failure are frequently covered events under California homeowners policies. Empire Tree Experts documents the damage, supports the claims process, and handles billing directly when applicable, so you focus on recovery instead of paperwork.
Sonoma County’s Mediterranean climate, with dry summers, wet winters, periodic drought, and real wildfire pressure, calls for trees with deep roots, drought tolerance, and reasonable fire resistance. If you’re replanting after a removal, these are strong long-term choices for Santa Rosa and surrounding properties. The UC Cooperative Extension and CAL FIRE Urban Forestry program both publish solid local guidance.
Coast Live Oak (Quercus agrifolia)
Native, drought-tolerant, and structurally strong. One of the defining trees of the North Bay landscape.
Valley Oak (Quercus lobata)
Iconic California native, deep-rooted and long-lived. Excellent shade tree for larger properties.
Blue Oak (Quercus douglasii)
Highly drought-tolerant native, well suited to dry inland Sonoma County sites.
California Bay Laurel (Umbellularia californica)
Aromatic native with dense foliage, good for shade and habitat. Note: keep at distance from oaks due to Sudden Oak Death pathway.
Big Leaf Maple (Acer macrophyllum)
Native deciduous shade tree, thrives near seasonal creeks and shaded slopes.
Western Redbud (Cercis occidentalis)
Smaller native ornamental with spectacular spring color. Well suited to residential landscapes.
Coast Redwood (Sequoia sempervirens)
Iconic, fast-growing, and tolerant of coastal fog. Best on larger properties with adequate moisture.
Madrone (Arbutus menziesii)
Striking native evergreen with distinctive bark. Site-sensitive but rewarding when placed well.
Toyon (Heteromeles arbutifolia)
Native large shrub or small tree, drought-tolerant with brilliant winter berries.
Crape Myrtle (Lagerstroemia indica)
Non-native but well-adapted ornamental, drought-tolerant once established. Long bloom season.
Santa Rosa and the broader Sonoma County region sit in a Mediterranean climate zone. Dry summers, wet winters, periodic drought years, atmospheric river events, and the ever-present reality of wildfire. Every season puts a specific kind of stress on your trees, and understanding the cycle helps you stay ahead of hazards before they turn into emergencies.

Late summer and fall bring the most dangerous combination in Sonoma County: dry fuels, low humidity, and offshore Diablo winds. Defensible-space clearing, ladder fuel reduction, and removal of high-risk trees near structures are the single most effective steps a homeowner can take.
From November through March, Sonoma County can take heavy, sustained rainfall on already-saturated ground. Combined with winter wind, that’s when trees with weakened roots, structural defects, or untreated disease tend to fail. Proactive pruning and hazard assessment ahead of the wet season is the best defense.
Multi-year drought cycles weaken even healthy native trees, reducing their structural integrity and making them more vulnerable to pests and disease. Drought-stressed trees often fail in the first heavy storm of the wet season.
Sudden Oak Death, bark beetles, and a range of fungal pathogens are persistent threats in Sonoma County’s oak and conifer canopy. Regular arborist inspection identifies infestations and disease progression before they escalate to full removal.
