Is This a Deal Breaker?
Insurance Impact
Branches touching the roof or siding are major red flags for insurance companies. Many insurers will refuse to bind coverage or require proof of trimming within 30 days of closing. If a storm knocks a healthy tree onto the house, insurance usually covers it — but insurers will deny claims for slow, progressive damage like rotting siding or worn shingles caused by neglected overhanging branches.
Mortgage Impact
Government-backed loans (FHA/VA) or strict appraisals may flag structural encroachment as a safety hazard and require the seller to resolve it before the loan can fund. Conventional loans are rarely affected unless the encroachment has caused visible structural damage.
How to Negotiate
Frequently Asked Questions
Can tree roots actually damage my foundation?
Yes. Large roots can alter soil moisture content, causing settlement, or exert physical pressure on older block foundations. If the inspector noted structural cracking alongside nearby trees, bring in a structural engineer for a full assessment. That said, most homes with nearby trees do not have root-caused foundation damage — it depends on tree species, soil type, and distance from the structure.
What if the encroaching tree belongs to my neighbor?
In most jurisdictions, you have the legal right to trim branches and roots up to your property line, provided your trimming does not kill the tree. You will bear this ongoing maintenance cost. If the neighbor's tree is causing damage to your property, consult a local attorney about your rights — laws vary significantly by state.
Do I need a permit to remove a tree on my own property?
Many cities, especially on the West Coast and in the Northeast, require permits to remove trees over a certain trunk diameter, even on private property. Permits typically cost $50-250. Check your local zoning laws before removing any tree — fines for unpermitted removal can be substantial, sometimes thousands of dollars.
Should I hire an arborist or just a general tree service?
For routine trimming of branches away from the house, a licensed and insured tree service is fine. If you need an assessment of the tree's health, root system impact on the foundation, or whether a large tree should be removed, hire a certified arborist (look for ISA certification). Arborists provide professional opinions that carry weight in negotiations and insurance discussions.
Are climbing vines on the house actually a problem?
Yes. Vines like ivy look charming but their rootlets dig into brick mortar, wood siding, and stucco. When eventually removed, they often take the surface material with them, requiring expensive repairs. Vines also trap moisture against the wall and provide hidden pathways for insects. If you want greenery on the house, consider installing a trellis system with a gap between the vines and the siding.
