Wind mitigation fbc certification

I’m looking for some confirmation to this question: It’s a situation I haven’t come across before regarding roof certification for a wind mit. Have a client that just had a brand new roof installed. They also have a small back porch with a rolled asphalt roof that, according to the permit was installed in 1995. The insurance company will not allow the FBC certification for the new roof because of it. I was always under the impression that the “main roof structure” was the one that had to meet the requirements and not a roof that is not part of the main structure. Can anyone confirm this…code reference etc.? Thanks. Please email me your comments at : rick.atechhomeinspection@gmail.com

That is correct.
Is the back porch roof attached to the homes truss system or attached to the fascia?

Depends… As Roy was implying, it depends on if it is over open patio area, or over a finished space.
If it is rolled roofing, it is likely over a finished space, in which case, ALL roofing needs to be installed after 3/1/02 to meet the building code.

That would then be selected “C” One or more roof coverings do not meet the requirements

If it’s structurally attached to main roof it needs to be accounted for whether or not if it’s a covered patio or closed in space. If it where to blow off it would effect the main roof structure.
But if it is attached to just facia or to wall under soffit it does not count.
If unsure when in attic look at end of trusses to main roof and see if flat roof joists are attached to tail of main house trusses.

I think he is referring to the roof coverings, not the roof geometry, but he has not clarified.

I think that is his confusion. “main roof structure” applies to the geometry, but “roof coverings” being under newer building codes applies to all coverings over finished space.

Even if he is referring to roof covering , I believe you still need to report any roof covering as long as the geometry of roof is attached to main roof structure regardless if it’s a covered porch or not.
