By October 1, 2007, the Florida Building Commission was required by the Florida Legislature to adopt and develop a couple of sets of requirements by rule, "which take immediate effect" and which shall be incorporated into the next edition of the Florida Building Code. At least one purpose, and likely the dominant if not the only purpose, was to encourage mitigation or prevention of future Hurricane Damages and resulting Catastrophe Claims. More solid structures, particularly homes, should reduce Hurricane Claims and in turn, Homeowners Insurance premiums and Property Insurance premiums -- where such Coverage is available. See previous posts on this Web Log for information about developments which affect both premiums and availability of Coverage for Hurricane and other Catastrophe Claims.
Here are some of the important new requirements imposed by the Legislature in Florida Statute Section 553.844, entitled, "Windstorm Loss Mitigation; Requirements for Roofs and Opening Protection."
Single-family residential structures, unlimited by value of the structure, are in one group. Not all single-family residential structures are addressed by the legislation, however. The requirements apply to (1) single-family residential structures that are (2) built on site, (3) "constructed prior to the implementation of the Florida Building Code [Fla. Stat. ยง 553.73, 'Florida Building Code', was first enacted in 1974]", and (4) undergoing a "roof replacement". When those things come together, then the new roof has to incorporate and comply with:
"Secondary water barriers for roofs and standards relating to secondary water barriers."
* * *
"Strengthening or correcting roof-decking attachments and fasteners during reroofing".
Another set of requirements applies to certain -- but not all -- buildings with "an insured value of $300,000 or more" or that have "a just valuation for the structure for purposes of ad valorem taxation of $300,000 or more," and which receive a "roof replacement". Such buildings must add "[p]rescriptive techniques for improvement of roof-to-wall connections" when the roof is replaced.
The executive director of the Florida Roofing, Sheet Metal & Air Conditioning Contractors Association, Inc. is quoted as the source in a newspaper report for an estimate that water-barrier requirements applicable to the first group of site-built single-family homes above, would add between $1,600.00 and $4,000.00 to reroof a home with a 4,000-square-foot roof.
Additional costs to reroof a single-family residential building on the coast, i.e., in the second group above, would according to the same source add at least about $5,000.00 to a three-bedroom home, for example, in Volusia or Brevard County, Florida. (The second group above does not appear to be limited to single-family residential buildings under the statute.) Here is a link to the newspaper report published in the Orlando Sentinel on Friday, October 5, 2007: Robin Benedick, "New Hurricane-Safety Law is Raising the Roof on Costs" Page A1, Col. 3 (Orlando Sentinel, Friday, October 5, 2007). The newspaper report was originally published in the South Florida (Ft. Lauderdale) Sun-Sentinel: Robin Benedick, "Cost of Replacing Roof Goes Sky High Under New Law" (Sun-Sentinel.com, Thursday, October 4, 2007).
The next Hurricane Damage Claims in Florida will tell the tale of whether Insurance Coverage will be more widely available, or at a higher or lower premium, as a result of these "mitigation" or damage-prevention efforts. Until then, roofing contractors are apparently not happy as a result of these efforts.
