Introduction
Trees fail quietly for months before they fail loudly. The crack that finally lets go during a windstorm usually started as a hairline fracture back in spring, and the root that finally releases its grip on the soil was often rotting underground since last winter’s rains. When a tree appears dangerous to the untrained eye, the damage is often so extensive that removal is not only the best option; it’s the only safe option.
That’s the gap Archon Tree Services exists to close, catching these failures while they’re still fixable instead of after they’ve landed on a roof.
This guide tells you exactly what to look for on your own property ahead of fall winds, why each warning sign is important structurally, and when a problem has crossed over from “keep an eye on it” to true emergency territory.
Common Hazard Signs
Most hazard trees give off more than one warning sign at once. One yellowing branch alone rarely means much but add to that fungal growth at the base and a slight lean, and you have a tree failing on multiple fronts at once.
The signs worth tracking include a trunk lean that wasn’t there last season, vertical cracks or seams in the bark, dead wood scattered through an otherwise green canopy, mushroom-like conks growing near the root flare, and soil that’s started lifting or cracking around the base. Each points to a different mechanical problem happening under the surface, and each is likely to get worse over time rather than improve.
The danger of fall lies in its timing. Late-summer walkthroughs are the only way to spot problems that a mid-storm glance from a car window will never catch. As leaves begin dropping and wind speeds pick up, trees that have been quietly weakening all summer meet their first real test.
Leaning Tree Risks
Not all leans are a problem. Trees that grow toward available light often develop a permanent, stable lean early in life and never move. The question is whether the lean is new.
A trunk that has shifted angle within the past year, especially following heavy rain or a prior windstorm, usually means the root plate has partially separated from the soil. Arborists call this phenomenon “root plate heaving,” and it often shows up as a crescent-shaped crack or mound of raised soil on the opposite side of the lean, a detail most homeowners walk past without noticing. That separation tends to grow with each subsequent storm, rather than self-stabilize, if left alone.
Cracked Trunk Issues
A tree with a visible trunk crack is already halfway to falling; the only question is which storm finishes the job.
Bark splits from rapid growth heal over and pose little risk. Cracks that run into the heartwood are different: they widen with every gust as the trunk flexes, and research on windstorm damage consistently shows that trunk breakage, while less common than branch failure, causes some of the most severe property damage because the entire upper canopy comes down at once. If you see a crack with sap running, a hollow sound when you tap it, or dead wood at the edges of the crack, there is no more waiting and seeing.
Dead Branch Dangers
Dead wood loses the flexibility that lets healthy branches bend and shed wind load. It doesn’t sway with the storm; it just snaps. Research monitoring windstorm damage to city trees has found that most storm-related tree failures are from broken branches that far exceed the combined effect of entire trees being uprooted or broken trunks.
Failure Type | How Often It Happens in Storms | Typical Trigger |
| Branch breakage | Most common | Dead or weak-jointed limbs |
| Trunk breakage | Less common, high severity | Internal decay, cracks |
| Uprooting | Least common, most catastrophic | Root disease, soil failure |
Because dead limbs often hide behind live foliage until autumn leaf drop, they’re one of the easiest hazards to miss during a casual walk around the yard. A limb that appears small from the ground can weigh several hundred pounds by the time it reaches the trunk, more than enough to cave in a roofline or total a parked vehicle.
Root Damage Problems
Roots fail silently, and this is what makes them the most dangerous category on this list. A tree may be in perfect health above ground, and yet its anchorage system may be failing below.
Laminated Root Rot
Douglas-fir, grand fir, and mountain hemlock, three of the most common conifers across Western Washington, are highly susceptible to laminated root rot, a fungal disease that decays roots from the inside out. Infected trees often develop thin, rounded crowns and a “distress crop” of cones before succumbing to windthrow, sometimes years after the initial infection. The disease is transmitted by direct contact between roots, so one infected tree can gradually influence the health of its neighbors.
Soil Compaction and Trenching
Douglas-fir, grand fir, and mountain hemlock, three of the most common conifers across Western Washington, are highly susceptible to laminated root rot, a fungal disease that decays roots from the inside out. Infected trees often develop thin, rounded crowns and a “distress crop” of cones before succumbing to windthrow, sometimes years after the initial infection. The disease spreads through direct root-to-root contact, so one infected tree can gradually influence the health of its neighbors.
Storm Preparation Tips
- Walk the property in late summer, before storm season, and check for the signs above.
- Clear dead wood from anywhere near rooflines, driveways, or power lines.
- Note any recent digging, trenching, or grading near mature trees.
- Photograph trees you’re uncertain about and compare them month to month.
- Book inspections early; schedules fill quickly once storm warnings start.
Property managers face a sharper version of this risk. A limb falls over a parking lot or entrance, and it’s not just a repair bill; it’s a liability exposure, which is why our commercial tree services are based on scheduled, documented inspections, not reactive cleanup after the fact.
Safe Tree Removal
Removing a confirmed hazard tree, particularly one leaning toward a structure or fence line, isn’t a project for guesswork. Weight distribution, lean direction, and everything within the drop radius all have to be mapped before a single cut is made.
That’s where zero-impact hazard tree removal matters: sectioning the tree from the top down using ropes and rigging so nothing around it gets damaged. After a storm, we also field frequent calls about storm-damaged trees already leaning on a neighbor, resting against a roofline, or split mid-trunk, situations that carry extra risk because the tree is under abnormal stress and needs experienced rigging to bring down safely. Trying to do this kind of removal without the proper equipment is one of the most common ways that storm cleanup becomes a second emergency.
Take Steps to Protect Your Property Before the Next Storm
Fall storms in the South Puget Sound don’t give much warning, and the signs covered here, from sudden leans and trunk cracks to hidden root disease, are the difference between a routine trim and an emergency call after the damage is already done. Catching these problems early is almost always cheaper, safer, and less disruptive than dealing with their aftermath.
Since 1989, Archon Tree Services has provided residential tree removal, pruning, and disease management across King, Pierce, and Kitsap counties, backed by a certified arborist and a satisfaction guarantee on every job. Our team offers tree removal services, tree safety assessments, and round-the-clock emergency tree services for homeowners and businesses throughout Tacoma, Bremerton, Gig Harbor, Port Orchard, and Silverdale, WA.
If any of the warning signs above sound familiar, don’t wait for the next windstorm to find out how serious the problem really is. Schedule a certified arborist inspection with our team today at (253) 858-8733.
