Although it is helpful, if you are uncomfortable with allowing for interior access, it is not required.
Our inspection consists of over 80 data points that have to deal with mainly the exterior of the home, and are not limited to just the roof. When assessing a roof, it is important to take all factors into consideration!
When trying to pin-point a specific leak, interior access is helpful in helping track it down.
Allowing your inspector to take a look at the leak, and showing them is helpful in improving the overall experience.
The more information that you are willing to provide our team, the easier it is for us to help you!
