How quickly do I need to act if a tree looks dangerous?

If a tree is leaning toward a structure, has recently cracked, or shows obvious structural failure, treat it as urgent. Schedule an assessment within 24–48 hours rather than waiting. In the meantime, keep people and vehicles away from the fall zone. Buffalo's weather can accelerate tree failure rapidly — especially after a wet spring or ice event.

Does emerald ash borer mean my ash tree needs to come down?

Not immediately in all cases, but ash trees with significant EAB infestation typically cannot be saved without expensive, ongoing treatment. An arborist can assess the extent of damage and tell you whether treatment is cost-effective or whether removal is the better long-term decision. In heavily infested trees, removal is usually the safest outcome.

What is a widow maker?

A widow maker is a large dead branch hanging in the crown of a tree — often not visible from ground level — that can fall without warning. They are extremely dangerous, especially in trees over 40 feet tall. Dead branches 4 inches in diameter or larger in the upper crown should be removed by a professional as soon as possible.

Q: How do I know if a tree needs to be removed?

The most reliable way is to have a certified arborist assess the tree on-site. Key warning signs include significant lean toward a structure, major trunk cracks or cavities, dead crown with no leaves in summer, large fungal growth at the base, and root damage from construction or disease. A tree showing multiple signs simultaneously should be evaluated promptly.

Q: Can a tree be saved instead of removed?

Sometimes, yes. Trees with isolated dead branches can often be saved with targeted pruning. Trees with certain diseases can be treated. Structural issues like co-dominant stems can sometimes be managed with cabling. The key is getting an honest assessment from someone who can tell you when treatment is realistic versus when removal is the only safe option.

Not every struggling tree needs to come down. Sometimes targeted trimming or treatment can save a tree that looks alarming from the outside. But some trees have reached the point where continued presence on your property is a genuine safety risk. Knowing the difference can save you thousands in repair costs — or prevent a serious injury. Here are seven signs it's time to seriously consider tree removal.

Sign 1: Significant lean toward a structure
Sign 2: Major trunk cracks or cavities
Sign 3: No leaves in the growing season
Sign 4: Heavy fungal growth at the base
Sign 5: Root damage or soil heaving
Sign 6: Large dead branches (widow makers)
Sign 7: Storm damage that compromises structure
When to get a professional assessment
Frequently asked questions

Sign 1: Significant lean toward a structure

Some lean is natural and develops gradually over decades as a tree grows toward light. What's concerning is a sudden or rapid lean — especially after a storm, prolonged wet period, or soil disturbance. When a tree is leaning toward your house, garage, or power lines at more than 15 degrees from vertical, and especially when you can see soil heaving or root lifting on the opposite side, that's a tree that needs to be evaluated immediately.

Sign 2: Major trunk cracks or large cavities

Not all cracks indicate failure risk, but deep longitudinal cracks running vertically along the trunk, cavities that penetrate more than one-third of the trunk diameter, and cracks near branch attachments are serious structural concerns. Co-dominant stems — where a tree has two major trunks growing from a single point — are prone to splitting under snow load or wind, particularly silver maples and Bradford pears, both common in the Buffalo area.

Sign 3: No leaves in the growing season

If a tree that normally leafs out by late April is still bare by mid-May, or if the crown is mostly dead with only scattered foliage, the tree is likely in terminal decline. This is particularly common in ash trees affected by the emerald ash borer, which has devastated the ash population across Buffalo, Amherst, Tonawanda, and the entire Western New York region. A completely bare crown in summer means the root system or vascular tissue has failed.

Sign 4: Heavy fungal growth at the base

Shelf fungi (conks) growing from the base of the trunk or major roots are an indicator of internal decay. Some fungi attack the heartwood, leaving the outer wood structurally intact for years while the interior deteriorates. By the time you see visible fungal fruiting bodies, the interior may already be significantly compromised. Large conks on a mature tree near a structure warrant immediate evaluation.

Sign 5: Root damage or soil heaving

Roots that have been cut by construction, trenching, or driveway work can destabilize a tree without obvious above-ground signs for several years. Similarly, soil heaving on the windward side of a lean indicates the root plate is already lifting. Trees that have lost more than 30–50% of their root zone from any cause have a significantly elevated failure risk and should be professionally evaluated.

Sign 6: Large dead branches in the upper crown

Dead branches 3 inches in diameter or larger in the upper crown — sometimes called widow makers — can fall without warning, especially in wind or after ice loading. They're particularly dangerous because they're often not visible from the ground until they're directly overhead. Buffalo's ice storms are notorious for shaking loose dead wood that has been hanging for years. A professional inspection of the full crown can identify and remove these hazards before they come down on their own.

Sign 7: Severe storm damage

A tree that has lost more than 50% of its crown in a storm, has a major split at the main trunk, or is hanging over a structure is generally beyond saving. Even if the remaining portion looks healthy, the loss of crown mass creates long-term structural instability. For emergency storm-damaged tree removal in Buffalo and Western New York, time matters — call quickly to prevent further damage.

When to get a professional assessment

If your tree shows one of these signs clearly or multiple signs in combination, don't wait. The right call is a professional risk assessment from a certified arborist — not just a removal quote. Our arborist services include on-site tree risk assessments for Buffalo, Amherst, Cheektowaga, Tonawanda, and West Seneca properties. We'll give you an honest answer about whether removal is necessary or if alternatives exist. Also check our guide on tree removal costs in Buffalo NY so you can budget realistically, and review permit requirements for tree removal in Buffalo before scheduling work. The ISA tree risk assessment resources explain what a professional hazard evaluation involves.
