Layers of roof

[Wayne Collier]

Would like to hear what other inspectors have to say about this.

Metal roof nailed (or screwed) to wood shake or wood shingles? If that's what I'm seeing, the fasteners can't be expected to hold during high winds. Many probably hit the gaps in-between.

[Wayne Collier]

They are wood shakes under metal. Overall the metal roof is in good condition and has a good appearance but underneath are wood shakes. Can only note it,it's not an insurance inspection but can't help but wonder what an insurance co thinks about such as this.

Is this off a back of garage, patio enclosure?

No roof drainage, do you have a picture from a distance to see what the roof covering is attached to?

Seems like a hack job but I would like some more info.

Thanks Wayne

I am no metal roof expert but there seems to be some issues like lack of roof drainage, what about ventilation? Like others said suspect to blow offs, how is it fastened? Seems like a cover up.

[Wayne Collier]

I think it is a post hurricane charley roof job. We see alot of this in the area because after the storm there were a shortage of contractors and materials. I think ventilation is an issue as well as wind. An insurance company might take issue with it at some point but until then not much you can really do but make a determination of what,where, why and who. I appreciate all who comment and share expertise and advice.

I can tell you what Firestone building products university school instructor stated first hand to never install metal over any other roof covering period. Not only is there no proper way to attach to the wood shingles the metal moves and scratches the paint off on the back side and the metal will start to rust

[Wayne Collier]

Thats good info, Thanks

Unconventional at best, needs a roofer.

Up to 1/8" per foot. The longer the run, the more movement.

Wayne,
It's probably a functional system, while not being a desired or approved system.
Issues:
1 - Even though the eves show tongue and groove decking, the roof is probably actually on perlings. That gives it a very low uplift rating.
2 - The maximum allowable layers of roofing, according to the FBC, is two. When the time comes to replace this roofing system, both layers will need to be removed which will add to the cost.
Otherwise, no leaks, no issues.

Replace it. It is not an approved application. It may be functional as someone mentioned above, for now, but what happens when another strong storm pulls thought. Don't you guys have permits in that part of the country?
