If so, do they use it? If so, do they walk on roofs, yes even tile roofs?
I got into a discussion with another home inspector about walking on roofs. He appears to be a good and qualified home inspector but disagreed that a consumer should be concerned if their home inspector walks on roofs.
I'll let this one case stand as an example and you be the judge. Of course there are numerous other reasons, but I'll use one illistration.
The example was for an $8.5 million home by the beach, 7,900 square feet of living space. With that size of house it should be obvious that looking at the roof from the roof edge would provide an extremely limited view due to the size of the home.
I started at the roof edge and everything looked fine.
Then I ascended on my ladder. What a beautiful view. You couldn't have enjoyed that from the roof edge, but I digress.
There were some broken tiles that could not be seen from the ground or the roof edge.

Then I saw this enormous skylight, which had parapet walls about 3-ft high. This would never have been seen by the roof edge, impossible. Only by walking the roof.

Then I had to climb down the small wall and take a closer look. That black hole to the right of the skylight is a drain. It is obviously missing a drain cover.

Big deal? That's only a $5 item. That's true. But what if debris falls inside and clogs the drain. Then a heavy rain comes and water backs up. The water starts to fill the area and the water fills up like a pool because of the small wall. Then you have standing water on top of the skylight, and guess what, you get a beautiful waterfall inside you house, just what every homeowner dreams of.
The moral of the story is twofold: First, this would not have been discovered without walking on the roof. Second, even small dollar items can make a big difference to a homeowner.
Now I guess I'm lucky. I just so happen to live close to the nations largest roof tile manufacturer, MonierLifetile. I took a continuing education class there and part of the class was how to walk on tile roofs.
So hopefully next time you or someone you know is getting a home inspection, make sure the inspector will walk on the roof (as long as weather permits, it's not too high and there are no other hazards).
By the way, this was a custom built, new construction home that had not been occuppied yet. Another reason to get those new home inspected also.
gOOD jOB!
