You should not trim an oak tree in the summer. Oak trees are especially susceptible to disease, and open tree wounds are an invitation for beetles that carry tree-killing fungus. If there’s no risk that the oak tree will do damage to your property or hurt someone, it’s best to save the trimming for fall or winter. If you can, seal the wound with latex to prevent fungus from getting inside.

Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.

The depth of tree roots depends on the species. Trees like oaks and maples can have root systems that grow down 20 feet or more. However, trees that grow in shallow soils will have roots that go only a few feet down. Research how your tree species grows in your climate area to estimate root depth.

Consumers typically do not need to worry about the cost of tree insurance, as professional tree service companies pay for their own coverage. For a tree service business, an average U.S. policy covering about $1 million in general liability costs roughly $40 a month or $500 a year. More extensive policies, providing between $500,000 to $2 million in coverage, can cost between $3,000 and $6,000 annually, depending on the company's size and scope of work. Tree service professionals should speak with an insurance company to determine the right plan for their business.
