Hurricane Mitigation Retrofit Q & A for Re-roofing
1. Q: Where can information be obtained for the of hurricane mitigation retrofit requirements? A: The information can be found in the Florida Building Commission’s Hurricane Mitigation Manual Retrofit Techniques, titles: “Hurricane Mitigation retrofits For Existing Site-Built Single Family Residential Structures”. This reference can be viewed on the Building Division’s website at: http://www.pbcgov.com/pzb/Building under “News Releases”.
2. Q: Are all single family re-roofing permits subject to the requirements for Hurricane Mitigation Retrofit? A: Yes. All single family site built homes that are permitted for re-roofing will be required to meet the requirement for a Secondary Water Barrier as required by Section 201.2 of the Manual. However, the requirement for enhanced roof to wall connections is only applicable to single family homes that were not built under the Florida Building Code (permit applied for prior to March 1, 2002) and with a value of $300,000 or more, based on insured value or assessment for taxation purposes.
3. Q: What additional paperwork is required if the home value is less than $300,000? A: The Hurricane Mitigation Retrofit Supplement needs to be completed, and proof of the home value presented. This can be a summary page from the insurance company or a print-out from the Palm Beach County Tax Appraiser’s Office. This information is available on their website at: http://pbcgov.com/papa/aspx/GeneralSearch/GeneralSearch.aspx?p=papa

6. Q: If the home requires enhanced roof to wall connectors, can a roofing contractor do the work?
