- Acting quickly on a hazard, rather than waiting, is usually what keeps a limb or leaning tree from becoming a much bigger problem.
- Grant Brothers responds with ISA Certified Arborists trained to ANSI A300 and Z133 safety standards, not just a crew with chainsaws.
- Photographing damage before cleanup begins helps homeowners with insurance claims.
Northern Virginia’s weather swings hard throughout the year, from ice storms and heavy wet snow in winter to violent summer thunderstorms and the occasional remnants of a tropical system. Every one of those events puts stress on trees, and every season brings its own pattern of emergency calls. After responding to storm damage across Fairfax, Loudoun, and the surrounding counties, Grant Brothers Tree Service has seen the same handful of emergency tree problems come up again and again. Knowing what they look like, and what to do the moment you spot one, can make the difference between a manageable repair and a much bigger, more expensive mess.
Here are top 10 emergency tree problems Grant Brothers handles across Northern VA –
Fallen Trees on Homes, Cars, or Fences
The most urgent call we get is a tree that has already come down, on a roof, across a driveway, onto a car, or through a fence line. These calls demand immediate attention, both for safety and to limit further damage. A tree resting on a structure can still be under tension from broken limbs or a partially uprooted root system, which means removal has to be handled carefully rather than just cut apart piece by piece.
If a tree falls on your home in Centreville, Reston, Burke, or anywhere else in our service area, the first priority is keeping everyone away from the area until a professional crew arrives. Trees under load can shift unexpectedly, and downed power lines are a real possibility if the tree contacts an overhead line on its way down. Our emergency crews assess the load path before making a single cut, using rigging to control how each section comes down so nothing shifts unpredictably onto the house, car, or people below.
Hanging Limbs and “Widow Makers”
A hanging limb, sometimes called a widow maker in the tree industry, is a broken branch still caught in the canopy above, held up by other limbs rather than fully attached to the tree. These are some of the most dangerous hazards we deal with, because they’re easy to miss from the ground and can fall without warning, hours or even days after the storm that caused the break.
After any significant wind or ice event, it’s worth doing a slow visual scan of the trees around your home, driveway, and any area where people walk or park. Look up into the canopy for broken branches resting at odd angles, bark that’s split but not fully separated, or debris caught higher in the tree than it should be. If you spot anything that looks loose or broken but hasn’t fallen, keep people and vehicles clear of that area and call for a professional assessment rather than trying to knock it down yourself.
Leaning Trees After Storms
A tree that’s suddenly leaning, especially one that was standing straight before a storm, is a sign that its root system has been compromised. Saturated soil after heavy rain makes this especially common in Northern Virginia, since wet ground loses much of its ability to hold a root plate in place against strong wind. A newly leaning tree, particularly one near a house, driveway, or property line, should be treated as an emergency even if it hasn’t fallen yet.
Some leaning trees can be stabilized or safely removed with time to plan the job. Others are actively failing and need immediate attention. The distinguishing factors, how much the root plate has lifted, whether soil is cracked or heaved around the base, and how large the tree is, aren’t always obvious to a homeowner, which is exactly why this is a call for a certified arborist rather than a guess-and-wait approach.
Split Trunks and Co-Dominant Stem Failures
Many mature trees develop what’s called a co-dominant stem, two main trunks growing upward from roughly the same point instead of one central leader. These unions are naturally weaker than a single trunk, and they’re a common failure point during high winds or heavy ice loading, especially in older shade trees found throughout Vienna, McLean, and Great Falls neighborhoods.
A split trunk is often partially attached, which makes it particularly unpredictable. One half may still be structurally connected while the other has broken away, creating a load that can shift with wind or even just the tree’s own weight. This is not a situation to address with a homeowner’s chainsaw. It requires rigging and careful sequencing to bring each section down safely.
Trees Blocking Driveways and Roads
Beyond structural hazards, fallen trees frequently block driveways, private roads, and shared access points, particularly after ice storms in areas like Chantilly, Herndon, and Springfield. While this may seem like a lower priority than a tree on a roof, it becomes urgent quickly if it’s blocking emergency vehicle access or preventing someone from getting to work, school, or medical care. Our crews prioritize these calls based on both safety and access needs, which is part of why fast response time matters as much as the technical skill to do the work safely.
Power Line Contact
Any tree or limb that has fallen into, or is leaning against, a power line needs to be treated as an electrical hazard first and a tree problem second. Downed or entangled lines can live even if they appear inactive, and contact can be lethal. If you see a tree touching a power line, keep everyone, including pets, well away from the tree, any metal fencing nearby, and the ground directly beneath the line, and contact the utility company immediately in addition to calling for tree removal. Our crews coordinate with utility providers when a job involves energized lines, rather than assuming a line is safe to work around.
Root Plate Heave and Soil Cracking
After a major storm, it’s common to see a ring of cracked or lifted soil around the base of a tree that’s still standing but has shifted. This root plate heave is an early warning sign that a tree’s anchoring has been partially compromised, even if the tree itself looks intact above ground. Left unaddressed, these trees are at elevated risk of failing in the next significant wind event, sometimes with much less provocation than the storm that first loosened them.
Ice and Heavy Snow Damage
Winter storms bring a different kind of emergency: limbs bent and snapped under the weight of ice or wet, heavy snow. Evergreens and trees with dense, multi-stemmed canopies tend to see the most breakage, since ice accumulation adds significant weight quickly. Unlike wind damage, which tends to snap or uproot, ice damage often leaves partially cracked limbs still hanging in place, which is exactly the hanging-limb hazard described above.
Flooding and Saturated Root Zones
Northern Virginia doesn’t see hurricane-force storm surge like the coast, but prolonged, heavy rainfall creates its own version of the same problem: soil that stays saturated for days can no longer hold a tree’s root system securely, even without a single strong wind gust. This is especially common along low-lying properties near streams, drainage easements, and areas with heavy clay soil that don’t drain quickly, which describes a fair amount of Northern Virginia terrain.
Trees standing in saturated ground for extended stretches are at meaningfully higher risk of failure even during relatively modest wind events that wouldn’t threaten a tree in well-drained soil. Homeowners in low-lying yards or near retention ponds should pay particular attention to trees after multi-day rain events, watching for the same warning signs described above: new leaning, cracked soil at the base, or exposed roots that weren’t visible before.
Storm Sequencing and Cumulative Damage
One pattern that catches homeowners off guard is cumulative damage from a series of storms rather than a single major event. A tree that loses a large limb in one storm, develops a crack that isn’t visible from the ground, and then faces a second storm weeks later is far more likely to fail on the second event, even if that second storm is less severe than the first. This is part of why we recommend a post-storm walk-around after every significant weather event, not just the ones that make the news, since minor, cumulative damage tends to build toward a failure that eventually looks sudden but wasn’t.
What to Do Before Help Arrives
In any of these situations, the guidance is largely the same: keep people, pets, and vehicles away from the affected area, avoid attempting to cut or move large limbs or leaning trees yourself, watch for and report any contact with power lines, and take photos of the damage from a safe distance if you’re planning to file an insurance claim. Documenting the scene before cleanup begins gives your insurer a clear record of what happened and when.

Yes. Hanging limbs can fall without warning and are one of the more unpredictable hazards after a storm, so they should be treated with urgency.
What should I do if a tree falls on a power line?
Stay well clear of the tree, the line, and the surrounding area, and contact both your utility company and an emergency tree service immediately.
Will Grant Brothers help with my insurance claim?
Yes, we document damage and can work directly with insurers on covered storm claims.
Should I try to remove a leaning tree myself?
No. A leaning tree’s root system may be compromised in ways that aren’t visible from the ground, and removal requires professional assessment and equipment.
