A raised edge on a walking surface is a trip hazard, and trips are among the most common causes of injury around a house. The inspector's job is to report it on the terms that matter to the occupant: where it is on the route people actually take, and that it presents a tripping risk. Two temptations pull away from that. One is precision — measuring against a municipal standard implies the inspector is enforcing a public works specification, which is neither their role nor useful to the client, and standards vary by jurisdiction anyway. The other is diagnosis — naming tree roots as the cause states something the inspection cannot verify without excavation, and the cause does not change the recommendation. Report the hazard, note its location on the path of travel, recommend correction.
