What would cause a roof to fail the wind mitigation inspection?

Thursday, April 15, 2021

When we pull up at a house to do a wind mitigation inspection, the homeowner often greets us with “So you’re here to do the roof inspection, right?” But, actually, an inspection of the condition of the roof is not part of a wind mitigation report and an inspector does not go on the roof. But we do verify, with a copy of the most recent roof permit, when the roof was last replaced—but that’s it. The intent is to be able to provide an insurance discount if the roof is newer and installed with roofing material that has a Florida Building Code (FBC) or Miami-Dade product approval at time of installation.

Most of the inspection is done in the attic, to verify that the roof trusses or rafters are securely tied-down to the wall, and that the roof sheathing is nailed to the trusses or rafters with the right nails at the correct spacing. To see other discounts that are possible, go to our blog post How can I get a better wind mitigation report and reduce the cost of my windstorm insurance in Florida?

    Although a roof covering that does not meet the standard will simply not get an insurance discount as far as the wind mitigation inspection is concerned, a roof that the form verifies as older (usually 20 years or more) will almost certainly trigger a requirement from your insurer for a roof inspection or roof replacement in order to obtain or renew insurance. So it is definitely possible to fail a wind mitigation inspection.
