A lot of answers, and a lot of good information! As John said, a 'roof inspection' is sometimes needed. But usually the Home Inspector (or building inspector) will look at the roof also. If the roof is very high or steep though, most of them will not get "on" the roof, but look at it from the ground with binoculars or something.
IF we can be of help to you, just let us know. We can assist with a roof inspection or do small roof repairs if needed. BUT, if everything is fine, we are happy to tell you that too.
Let us know if we can help!
