Tree Hazard Assessment
Identify potential tree risks before they cause damage
Professional Tree Risk Evaluation
Trees add beauty and value to your property, but they can also pose significant risks when compromised by disease, damage, or age. At 1 Tree Emergency, our certified arborists provide thorough hazard assessments to identify potential tree risks before they result in property damage, injury, or costly emergency situations.

What Our Hazard Assessment Includes
Our comprehensive tree hazard assessment evaluates multiple factors that contribute to tree risk:
Structural Integrity
We examine the tree's structure for weaknesses, including cracks, splits, leans, and poor branch attachments that could lead to failure.
Disease and Decay
Our arborists identify signs of internal decay, fungal growth, and disease that may compromise the tree's stability and health.
Root Condition
We assess the root system for signs of damage, decay, or instability that could lead to tree failure, especially during storms.
Site Conditions
Environmental factors such as soil compaction, recent construction, drainage issues, and exposure to wind are evaluated.
Our Assessment Process
When you schedule a hazard assessment with 1 Tree Emergency, our certified arborists follow a systematic approach:
- Visual Inspection: We conduct a thorough visual examination of the tree from root to crown, identifying visible signs of potential hazards.
- Advanced Diagnostics: When necessary, we use specialized tools such as resistographs, sonic tomography, or drones to assess internal decay or difficult-to-reach areas.
- Risk Evaluation: We assess the likelihood of tree failure and the potential consequences based on targets (structures, vehicles, pedestrian areas) in the vicinity.
- Detailed Report: You receive a comprehensive report documenting our findings, including photographs, risk ratings, and specific recommendations.
- Mitigation Plan: We provide clear recommendations for addressing identified hazards, which may include pruning, cabling, bracing, or removal when necessary.
When to Schedule a Hazard Assessment
Regular tree assessments are recommended, but certain situations warrant immediate evaluation:
- After severe storms or high winds
- When you notice visible damage, decay, or unusual leaning
- Before beginning construction near established trees
- When purchasing a new property
- If trees are located near structures, play areas, or high-traffic zones

Frequently Asked Questions
Common questions about our tree hazard assessment services
How much does a tree hazard assessment cost?
Assessment costs vary depending on the number of trees, property size, and assessment depth. Basic assessments typically range from $150-$300, while comprehensive evaluations of multiple trees or large properties may cost more. We provide a clear quote before beginning work.
How long does a hazard assessment take?
A typical assessment for a residential property with several trees takes 1-2 hours. Larger properties or those with numerous trees may require more time. The written report is usually delivered within 2-3 business days after the assessment.
Do I need to be present during the assessment?
While not required, we recommend being present at least at the beginning and end of the assessment. This allows you to point out specific concerns and receive immediate feedback from our arborist. However, we can conduct the assessment without your presence if needed.
Can a hazard assessment be used for insurance purposes?
Yes, our detailed assessment reports are often used for insurance documentation. They provide professional evaluation of tree conditions and risks, which can be valuable for both preventative measures and claims processing if damage occurs. Our reports include photographs and specific risk ratings.
