House Failures in Hurricanes

Bob is joined by Wayne Sallade, the emergency manager for Charlotte County, Florida. They stand before a residential property that has been condemned since the strike by hurricane Charley. Sallade explains that buildings built in the 60s, 70s, or early 80s -- prior to the Florida Unified Building Code -- were destined to fail in those winds. Roof failure with gable roofs that catch wind like a sail, lap siding that was ripped from the sides of homes, and failure of stick-frame construction to hold together through wind and wind uplift caused these buildings to fail. With another hurricane season looming, it is critical to remove these damaged buildings before they become wind-borne missiles threatening other structures. Sallade explains that demolition takes time and skilled, certified contractors. With so much devasatation in areas of Florida, there are not enough demolition contractors to complete all the work. He adds that a 50/50 rule specifies that any building damaged beyond 50 percent must be torn down and rebuilt. With zoning changes, it is often difficult for owners to rebuild in accordance with required materials and practices. Sallade then looks with Bob at older homes that survived unscathed, largely because they had hip roofs to deflect the wind, wind protection for doors and windows, and traditional Florida construction.

" We're going to chat now with Wayne salad -- Charlotte county emergency manager talked a little bit about some of the effects of this storm. On not just Florida in general but on the community here -- standing. Right in front of something that nine months later still largely destroyed and now I learn it's condemned. Tell us a little bit about the impact of the storm."

" And one of our big problems Bob as we go into another hurricane season is we've got hundreds and hundreds of properties look just like this one yeah we've got homes that look the day they did after hurricane Charley and that's a real real concern. Because recovery is not something that happens instantaneously. And it takes a lot of effort. To get these buildings down and and to begin the process of rebuilding our community and should another storm threatened. We've got some very serious issues to deal with in terms of flying debris."

" Now is the problem mostly just that the numbers are so -- there have been so many damaged buildings there aren't enough contractors to."

" They just aren't enough demolition companies to do it -- mean demolition. Is a tedious process has to be done right you can't just telling clear a site it's got to be done as evidence safely there's OSHA rules and regulations and getting contractors that are skilled. And do that for a living. Again there just aren't that many go around and they're spread pretty threat then across state of Florida you're going to Pensacola -- out of here right and so it's it's a big problem."

" Now were there some homes there were more susceptible to destruction in this hurricane and others yeah I mean anything -- pretty much. You could write off those that went through the -- wall of Charley that were built the 60s70s. Early eighties we're going to have damage particularly roof failure this example is probably from that appears to be there -- seventies very good example of pre. Forty unified building code. And a place that was built with materials and and wood frame construction. With lap siding and and just. We're really didn't stand a chance you can see. Where the damage is on this particular building that the winds did come around from the east and southeast as Charley passed over right and did its damage on this side of the building right and so it's it's unfortunate. That you see properties like this and people have to understand the 5050 rule that's out there. That if a property is damaged beyond the 50% level right it has to be replacing your -- in Internet SM cases. Zoning changes affect what can be re absolutely -- absolutely and and and and that gets into the whole insurance issue and having law and ordinance coverage on your property that protects you when the rules and regulations change it so that you can build a similar type of structure. For the amount of money that you might have available -- Yeah you get people are cut in you know -- have a real catch 22 right when you have a situation like like this one in particular. Now other homes like this lovely lavender house over here seem to have gone through storm pretty much unscathed well imagine now these people couple reasons one obviously point number one this house has a hip roof. Yeah gable roofs just don't make especially when they're facing the win and that gable is going to fail without brakes and gable end is like the sale. But the hip roof. Provides deflection of the wind -- and then that's key point number one number two they had window protection on this house Paramount to protecting a Florida home and keep the wind out. -- doors and windows. You're not going to get those uplift pressures and your house stands significant chance to survive and super."

" You know go back to the twenties and thirties are still intact."

" Isn't that amazing to take a look at old Florida construction. And and realize that we have hundreds and hundreds and hundreds of homes. Just like leaves. Throughout the -- gorda community that did just as well it's it's when I first got out into the community in fact is that day after the storm when we flew over the city. And I was able to look down and I mean these streets have been my home for forty years and I looked at some of these houses and I said. You gotta be kidding I can't believe that that's still there when I saw buildings all around that had failed miserably under the the wind forces."

" I think of them as baskets they they they're flexible they give in the wind but they they stayed there when he thanks for coming on the show thanks Bob all right pleasure."

Securing the Roof-Truss System
Securing the Roof-Truss System

Bob talks with Bill York and Rob Davis of FLASH (Federal Alliance for Safe Homes) about the construction of a storm-resistant roof system built with roof trusses. Bob reviews specifications for how to secure a wooden rootruss system to a steel structure. With the addition of steel fasteners, the building's roof will have an uplift resistance of about 850 pounds, making it capable of withstanding wind speeds of up to 140 mph. To secure the wooden structure to the steel shipping container, a steel piece or angle iron is welded to the top of the box and a threaded bolt is welded on to it. The bolt sticks through the wood, where it is secured by a nut and washer, transferring the load back to the steel box. In high winds the ends of the roof experience much greater force, so the first six feet of each end of the roof is secured by steel straps, giving the ends 1200 pounds of uplift resistance. Plywood sheathing that is 5/8-inch thick or 1 1/2 times thicker than sheathing specified by the Florida Building Code. Construction adhesives are also used to secure the sheathing, again going beyond code to make a stronger roof. Building codes require the use of eight-penny nails (2 1/2 inch nails) to secure the plywood to the roof framing, but FLASH's Blueprint for Safety specifies ten-penny nails to give 50 percent greater uplift resistance. With the use of ten-pennny nails and adhesive to secure the roof, the roof probably has twice as much uplift resistance as a roof built to code.

Rebuilding Florida After Four Hurricanes in 2004
Rebuilding Florida After Four Hurricanes in 2004

Bob is joined by Florida's Lieutenant Governor, Toni Jennings, and Secretary of the Department of Community Affairs Thaddeus Cohen to discuss the aftermath of the four hurricanes in 2004 and Florida's efforts to build back better. Lt. Governor Jennings briefs Bob on the destruction since Charley hit on August 13, 2004, followed by Frances, Ivan, and Jeanne. In Florida, more than 700,000 homes were damaged, 9.4 million residents were evacuated, and the state sustained 42 billion dollars in property damage. As Jennings points out, hurricane season is again upon the state and they have yet to repair from last year's storms. Still, she adds, it is evident that improved building codes -- in place after hurricane Andrew hit in 1992 -- have dramatically increased the storm-resistance of Florida's built environment. Bob asks about Florida's commitment to preparedness for upcoming storms. Secretary Thaddeus Cohen, himself a practicing architect, talks about the determination to use the $100 million in block grants to build back better, to put federal dollars to work to improve housing, and to build sustainable communities throughout Florida.

Roof Deck Construction
Roof Deck Construction

Bob and Chris Vila meet with David and Jed Walentas from Two Trees Development, the developers of the waterfront warehouse rehab, on the top of a nearby building to get some ideas for the project building's roof deck. In this example, the roof below the deck is a double-ply rubber membrane. Portions of the deck are made with pressure treated timbers and a renewable hardwood decking called ipe, although the majority of the surface area is concrete pavers. New York City building codes will be a major consideration in the construction of the Pepper Factory's roof configuration. Jed Walentas highlights some of the major factors, including the height of the safety railing and the percentage of combustible materials that can be used in rooftop construction.
