When you see those first dark clouds rolling in from the Pacific and weather forecasts calling for heavy rain and wind across Sonoma County, one question should be on your mind: “Are my trees ready for this storm?”
It’s not paranoia – it’s smart property management. Santa Rosa’s tree service winter storm season runs from December through February, and every year I respond to dozens of calls about fallen trees, broken branches, and close calls that could have been prevented. A tree that looks perfectly fine in October can become a serious hazard once 50 mph winds and saturated soil are in the equation.
Here’s what makes this tricky: you can’t control the weather, but you can absolutely control how prepared your trees are when the next storm hits. I’ve been doing professional tree removal in Santa Rosa for years, and I can tell you that the properties that come through storms unscathed are the ones where homeowners took action before the rain started.
Let me walk you through the exact steps to prepare your trees for winter storms, including the warning signs to look for and when to call in professional help.
Why Santa Rosa Trees Are Vulnerable During Winter Storms
Our Mediterranean climate is generally kind to trees, but winter storm season is a different story. We get months of dry weather, then suddenly we’re hit with heavy rainfall, strong winds, and saturated soil – sometimes all at once.
The problem isn’t just the rain. It’s the combination of factors that stress trees that have been bone-dry since spring. When soil becomes waterlogged suddenly, tree roots lose their grip. When wind speeds pick up in the hills above Fountaingrove or sweep through the valley floor near Rincon Valley, trees that seemed perfectly stable can fail without warning.
Add in the fact that many Santa Rosa properties have mature trees that have been growing for 30, 40, or 50+ years, and you’ve got situations where structural weaknesses might not be evident until wind and rain expose them. Tall eucalyptus trees, top-heavy palms, and even our native oaks can all become hazards under the right conditions.
Pre-Storm Tree Inspection: What to Look For
Before storm season kicks into full gear, walk around your property and look at every tree with fresh eyes. You’re looking for warning signs that a tree might not make it through the next big storm.
Dead or Hanging Branches: Look up into the canopy. Do you see any branches that are clearly dead, broken, or hanging? These are called “widow makers” in the tree industry for good reason. When the wind hits, these come down first. Even if they haven’t fallen yet, they’re ticking time bombs once wind speeds pick up.
Leaning Trees: A tree that leans slightly is often fine – that might be its natural growth pattern. But if you notice a tree has started leaning recently or if you can see soil lifting at its base, that’s a red flag. This is especially common after the first heavy rains of the season when soil suddenly becomes saturated.
Cracks in the Trunk: Walk around the base of your larger trees and look for vertical cracks, splits, or separations in the trunk. These indicate structural weakness. When wind loads hit during a storm, these weak points can fail catastrophically.
Root Problems: Look at the area around the tree’s base. Do you see exposed roots? Fungus growing? Soft, spongy soil? These all indicate root decay or damage. Since roots are what anchor a tree during high winds, root problems are serious business.
Trees Too Close to Structures: Measure the distance between your trees and your house, garage, or power lines. A tree doesn’t have to be touching your roof to be dangerous – if it’s within falling distance and shows any signs of weakness, it’s a hazard worth addressing.
If you’re seeing any of these warning signs, get a professional assessment. We can determine whether a tree requires removal, strategic pruning, or simply monitoring throughout communities from Santa Rosa to Sebastopol and beyond.

Strategic Pruning: Your Best Storm Defense
Here’s something most homeowners don’t realize: proper pruning isn’t about making trees look pretty. It’s about physics.
When wind hits a tree during a storm, it’s pushing against the entire crown – all those branches and leaves. The more surface area a tree presents to the wind, the more force it has to resist. Strategic pruning reduces that wind resistance by thinning the canopy and removing weight from the ends of long branches.
This is called “crown reduction” and “crown thinning” in the tree care industry, and it’s one of the most effective ways to storm-proof a tree. We’re not talking about topping a tree – that’s actually harmful and creates more problems. We’re talking about selective removal of branches to reduce weight and wind load while preserving the tree’s natural structure and health.
The best time for this work is actually right now, during winter. Trees are dormant, disease transmission is minimal, and you’re preparing them before the worst of storm season hits in January and February. If you have trees with heavy, extended branches that overhang your roof or driveway, having them professionally pruned before storms arrive is money well spent.
When Tree Removal Is the Right Call
Sometimes pruning isn’t enough. Sometimes a tree is too far gone, too damaged, or too dangerous to save.
I know it’s hard to make the call to remove a tree – especially a large, established tree that’s been part of your property for decades. But here’s the reality: it’s far better to remove a dangerous tree on your schedule than to have it come down during a storm at 2 AM, potentially onto your house or car.
You should seriously consider removal if:
- The tree is more than 50% dead or dying
- Significant structural damage exists (large cracks, severe lean, extensive decay)
- The tree has a history of dropping large branches
- Root damage or rot is compromising stability
- The tree’s location puts your home or family at risk if it fails
One customer in Bennett Valley learned this the hard way last winter. They had a large eucalyptus that we’d flagged as concerning. They decided to wait and see. During a January storm with winds gusting to 55 mph, that tree came down across their deck and put a hole in their roof. The emergency removal and repairs cost three times what scheduled removal would have cost.

Creating Your Storm Preparation Action Plan
Let’s turn this information into a concrete action plan you can execute before the next storm warning hits.
Start with a property walk-through. Grab your phone, take photos of every tree on your property, and document anything that concerns you. Dead branches, cracks, lean, proximity to structures – photograph it all.
Get professional eyes on concerning trees. If anything looks questionable, request an assessment. We’ll come out, evaluate your trees, and give you honest feedback about what needs immediate attention versus what can wait. We serve properties throughout Petaluma, Windsor, and all of Sonoma County.
Prioritize based on risk. Trees directly over your house or vehicles get priority. Trees near power lines need attention. Trees showing structural problems come before those needing only routine maintenance.
Schedule work before peak storm season. December is your window. By January and February, storm systems are rolling through regularly, and tree services get overwhelmed with emergency calls. Schedule preventive work now while weather is relatively calm.

What to Do If a Tree Falls During a Storm
Despite your best preparation, sometimes trees still come down during major storms. Here’s what to do:
If a tree falls on your house: Get everyone to a safe area away from the damage. If there’s risk of further collapse or significant roof damage, evacuate and call us immediately for emergency response. Learn more about emergency tree situations in our winter storm damage guide.
If a tree falls on power lines: Stay away – at least 30 feet minimum. Assume all downed lines are live. Call PG&E first, then call us. We regularly coordinate with utility companies and know the protocols for safely removing trees from power lines.
If a tree falls but isn’t causing immediate damage: You can usually wait until regular business hours for removal. Take photos for insurance purposes, establish a safety perimeter, and call us when conditions are safe for crews to work.
Document everything for insurance. Take photos and videos before anything is moved. Keep receipts for all work. Most homeowner’s policies cover storm damage and tree removal, but documentation is key.
The Cost of Prevention vs. Emergency Response
Let’s talk numbers, because I know cost is on everyone’s mind.
A typical pre-storm pruning for a medium-sized tree runs $300-$800, depending on size and complexity. Removing a hazardous tree before it falls typically costs $1,000-$3,000, depending on size and location.
Now compare that to emergency removal after a tree falls on your house: $2,000-$5,000+ for tree removal, plus thousands more in structural repairs, temporary housing if your home is uninhabitable, increased insurance premiums, and the stress of dealing with a crisis during a storm.
I’ve done this work long enough to tell you: every single customer who’s dealt with storm damage emergencies wishes they’d spent the money on prevention. Not one has said, “I’m glad I waited to see what would happen.”

Frequently Asked Questions
How early should I prepare my trees for Santa Rosa’s winter storms?
Ideally, complete any major tree work by mid-December. Storm systems can start rolling through as early as November, but the heaviest rain and strongest winds typically hit in January and February. By preparing in early December, you’re ahead of the curve and avoid competing with emergency calls for tree service availability. If you’re reading this in January or February, don’t panic – we respond quickly and can still help you minimize risk even during active storm season.
Does homeowner’s insurance cover preventive tree trimming or removal?
Generally no – insurance covers damage caused by a fallen tree but not preventive maintenance. However, if a tree falls during a storm and damages your home, insurance typically covers both removal and structural repairs. This is why prevention is cost-effective: you’re paying a few hundred to a few thousand now to avoid paying your deductible plus premium increases later. Some policies have specific exclusions for trees that were already dead or hazardous before they fell, so addressing known problems before storms hit protects your coverage.
Can I trim the trees myself to save money?
For small branches you can reach safely from the ground, sure. But for anything involving a ladder, working near power lines, or cutting branches over structures, hire professionals. Tree work is genuinely dangerous – it’s one of the most hazardous occupations in the country. We have specialized equipment, safety training, insurance, and experience to know what cuts to make without harming the tree or people. We also carry $2M liability insurance that protects you if something goes wrong.
What’s considered an emergency that requires immediate tree service?
A tree or large branch that’s fallen on your house, car, or power lines is an emergency – call immediately at (707) 775-0204. A tree that’s actively splitting or leaning severely toward a structure during a storm is an emergency. A large branch hanging precariously over a high-traffic area is an emergency. What’s not an emergency: a tree that’s been leaning for years without change, dead branches that are still attached and secure, or a tree that fell in your backyard away from structures. For those, schedule service during regular hours when it’s safer for crews to work.
