Comprehensive Tree Risk Assessment Services

Tree risk assessments are critical evaluations designed to identify unhealthy or damaged trees that may pose significant risks to people and property. Our certified arborists conduct these assessments with meticulous attention to detail, following the industry’s most rigorous standards. Depending on your specific needs, we offer three distinct levels of assessment:

Level 1: Limited Visual Assessment

  • Perfect for initial evaluation of large properties or multiple trees
  • Conducted by walking or driving past trees to identify obvious high-risk specimens
  • Efficiently screens multiple trees to determine if more detailed assessment is needed
  • Includes a professional summary report of findings with basic recommendations

Level 2: Basic Assessment

  • Involves a comprehensive 360° visual inspection of individual trees
  • Conducted without specialized tools but with expert observational techniques
  • Includes detailed documentation of species, diameter at breast height (DBH), structural defects, and risk factors
  • Provides a thorough risk assessment and mitigation report for each evaluated tree
  • Offers clear, actionable recommendations based on professional judgment

Level 3: Advanced Assessment

  • The most comprehensive evaluation for high-value or high-risk trees
  • Utilizes specialized equipment including bucket trucks for canopy access, compressed air tools for root collar examination, resistograph for decay detection, and sonic tomography
  • Delivers in-depth analysis of roots, stem, or crown conditions
  • Includes a detailed professional report with field observations, photographic documentation, testing results, and multiple recommendation options
  • Provides the data needed for making critical decisions about valuable or hazardous trees

A certified arborist provides expert consultation, assessment, and diagnosis backed by professional certification and scientific knowledge. While tree service companies perform physical work like pruning and removal, certified arborists offer specialized expertise in tree health, risk analysis, and complex problem-solving. Marquis Tree Services offers both certified arborist consultation and complete tree care services.

While not always required, professional arborist documentation significantly strengthens insurance claims by providing expert analysis of tree condition, failure causes, and damage assessment. Insurance adjusters often rely heavily on certified arborist reports for claims involving tree damage or liability.

A tree risk assessment is a systematic evaluation of tree condition, structural integrity, and potential for failure that could harm people or property. Our ISA-Certified Arborists use industry-standard methodologies to calculate quantified risk ratings and develop mitigation strategies. Assessment levels range from basic visual inspection to advanced testing with specialized equipment.

Assessment frequency depends on tree condition, age, and risk factors. High-risk trees near structures may require annual evaluation, while healthy mature trees might need assessment every 3-5 years. Our arborists provide specific monitoring recommendations based on individual tree conditions and site factors.
