This home had a significant – but not obvious from the outside – gap in the attic. I discovered it during the home inspection and made sure to alert my client, the buyer. Gaps like this are an easy entryway for animals and insects like bats, squirrels, birds, hornets, etc. If a bat colony decides to set up residence in your attic, it is quite costly to have them safely removed ($1500 or more in most cases). In addition to unwanted house guests, gaps compromise the weathertightness of a home and make it less efficient and more prone to water damage. Findings like these are yet another reason why a good home inspector is well worth the investment.
