Trunk & Bark Inspection
Check for these trunk warning signs during your walkthrough: 1. Deep vertical cracks - A crack you can fit a coin into means structural compromise. Severity: HIGH. 2. Bark peeling in sheets - Healthy bark sheds slowly. Large plates falling off indicate disease or internal decay. Severity: MEDIUM-HIGH. 3. Fungal growth on the trunk - Shelf fungi (conks), mushrooms, or bracket fungus means internal rot. If you can see it outside, the inside is worse. Severity: HIGH. 4. Hollow trunk or cavities - Tap the trunk. A hollow sound means the tree has lost structural wood. A cavity larger than 1/3 of the trunk diameter is dangerous. Severity: HIGH. 5. Leaning trunk - A tree that has recently started l...
Canopy & Branch Inspection
Look up and check for: 6. Dead branches (widowmakers) - Bare branches with no leaves during growing season. These fall without warning. Any dead branch over 2 inches diameter over your house, driveway, or walkway is an emergency. Severity: HIGH. 7. Hanging or broken branches - Cracked but still attached. One gust of wind finishes the job. Severity: HIGH. 8. Thinning canopy - Can you see sky through the crown where you couldn't last year? This indicates root problems or vascular disease. Severity: MEDIUM. 9. Lopsided or unbalanced crown - One side heavy, the other thin. Creates uneven weight distribution - windthrow risk. Severity: MEDIUM....
Root Zone & Base Inspection
Check the ground around each tree: 10. Soil heaving or mounding - Raised soil on one side of the base means roots are lifting. The tree is failing. Severity: CRITICAL. 11. Mushrooms at the base - Honey fungus clusters, or any significant mushroom growth within 3 feet of the trunk, means root rot. Severity: HIGH. 12. Recent soil disturbance - Construction, trenching, or grade changes within the "critical root zone" (1 foot per inch of trunk diameter) damages roots. Trees can fail 2-5 years after root damage. Severity: MEDIUM-HIGH....
Seasonal Inspection Schedule
Early Spring (March-April): Check for winter damage - cracked branches, split trunks from ice loading, trees that have started leaning. Late Spring (May-June): Check for leaf-out problems - trees that didn't leaf out on time, unusual discoloration, dieback in the canopy. Mid-Summer (July-August): Look for insect damage - exit holes, sawdust at base, heavy woodpecker activity. Check for drought stress. Fall (October-November): Assess canopy before leaf drop - note dead branches, structural issues visible when leaves thin. After Major Storms: Walk the property immediately. Check for hanging branches, cracked trunks, leaning trees, and root heave....
What to Do When You Find a Problem
If CRITICAL: Do not go near the tree. Keep family and pets away. Call a professional immediately: (517) 202-3840. If HIGH: Schedule a professional assessment within 1-2 weeks. Document with photos. Don't attempt DIY removal on large branches. If MEDIUM: Monitor quarterly. Take dated photos for comparison. Schedule professional assessment at your convenience. Insurance tip: Keep photos of all your trees in their current healthy state. If one fails and damages your property, these photos prove you maintained your trees responsibly - which strengthens your insurance claim....
