Tree Service questions, answered by experts

After a big storm, you may not be sure if a tree was struck or not. Look for the telltale long scars, like strips or gouges in the bark of the tree, running in sometimes jagged lines down the length of the trunk. These scars will often show vulnerable living wood inside the tree. It’s also common to see scorched or wilted leaves on the side or top of the tree where lightning struck.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

Tree roots can take weeks to years to die, depending on the method you use. Chemical herbicides take the least amount of time—typically between three and four weeks—while homemade methods, like covering an old stump with leaves, could take between seven and eight years. If you’re unsure which method to use or how quickly you need to act, consulting with a pro is always a good idea.

It enhances property aesthetics, improves tree health, and prevents safety hazards.

Your neighbor is not in a good position to know if your trees are truly dead or pose any kind of danger. That’s why hiring an arborist or tree service expert can be such an important part of the process. If the trees are still alive and don’t pose any threat, you’re in the clear (but you may want to document and photograph everything in case events turn sour down the road).

But if a tree is visibly dead and near the property line, you should remove it to be safe. If a dead tree falls on a neighbor’s property, they may have grounds to sue for negligence. If any branches on trees have died, it’s a good idea to cut them back for similar reasons.
