Hazard Tree Assessment on the North Shore
Not every leaning or ugly tree needs to come down, and not every healthy-looking tree is safe. A hazard assessment looks at the tree's structure and health and what it could hit if it failed. We connect you with independent local tree professionals who can assess trees and recommend options.
Why tree problems matter
Most trees are an asset, and no tree is completely risk-free. A few warning signs, though, are worth having a qualified arborist look at before the next storm.
Storms bring down weak trees and limbs
Strong winds and soaking rain soften soil and can overturn trees, and ice storms create hazards of their own. When a mature tree or a large part of it fails, it can damage homes, cars, fences, and utility lines.(ISA TreesAreGood: Recognizing Tree Risk)
Dead and hanging limbs are a common hazard
Large dead branches, detached or hanging limbs, cracks or splits in the trunk, cavities, rot, and mushrooms at the base are signs of possible defects. Evaluating how serious they are is best done by a professional arborist.(ISA TreesAreGood: Recognizing Tree Risk)
Emerald ash borer is killing ash trees here
This invasive beetle is devastating ash trees in Massachusetts and has been confirmed in Essex and Middlesex counties. Its larvae feed under the bark and can kill a tree, and the USDA Forest Service notes that removing declining ash is an ongoing public safety risk and cost for communities and landowners.(Mass.gov: Emerald Ash Borer in Massachusetts, USDA APHIS: Emerald Ash Borer, USDA Forest Service: Massachusetts Forest Health Highlights 2025)
Storm cleanup is dangerous work
Trees and limbs under tension can move unexpectedly when cut, and damaged trees may be touching power lines. Stay away from downed lines, call the utility, and leave climbing and chainsaw work to trained crews.(ISA TreesAreGood: Storm-Related Tree Damage, ISA TreesAreGood: Recognizing Tree Risk)
Signs you may need help
- Large dead limbs or a thinning crown
- Cracks, cavities, or mushrooms at the base
- A new lean, or soil lifting around the roots
- Ash trees with canopy dieback or bark splits
- A big tree near the house that you worry about in every storm
What the work typically involves
- Look at the whole tree. The assessor checks roots, trunk, branches, and canopy for defects and decay.
- Consider the target. Risk depends on what the tree could hit: a house, a driveway, a play area, or a road.
- Recommend options. Options include monitoring, pruning, cabling, or removal.
- Get it in writing. Ask for a written summary of findings and recommendations.
Every job is different. The pro you speak with will explain their own approach and pricing. Storm Tree North Shore does not perform, supervise, or guarantee any work.

Frequently asked questions
Who should do a hazard tree assessment?
Look for someone with arborist training. Ask whether an ISA Certified Arborist or Massachusetts Certified Arborist will do the assessment.
How do I know if my ash tree has emerald ash borer?
Common signs include canopy thinning and dieback, bark splits, woodpecker damage, and D-shaped exit holes. A professional can confirm it. The state tracks the beetle and asks that ash wood not be moved.
Can a hazardous tree be saved?
Sometimes. Removing defective limbs, reducing the crown, or adding cables can lower the risk. Sometimes removal is the safer choice.
How do I know if a tree on my property is dangerous?
The International Society of Arboriculture suggests looking for large dead branches, hanging or detached limbs, cracks or splits in the trunk or branch unions, cavities or rotten wood, mushrooms at the base, and recent root disturbance from construction. If you see any of these, have the tree evaluated by a qualified arborist.
Is emerald ash borer in my area?
Very likely. Mass.gov reports emerald ash borer has been detected in Essex and Middlesex counties, among others, and the whole state is part of the federal quarantine zone. If you have ash trees, an arborist can help you decide whether treatment or removal makes sense.
Should I cut up a storm-damaged tree myself?
It is safer not to. Limbs under tension can spring back when cut, and damaged trees can be in contact with power lines. Never go near downed lines, call your utility, and have trained tree workers handle the cleanup.
