Is Your Deck Safe? Experts Say 20 Million American Decks Could be at Risk

May 02, 2008

PLEASANTON, Calif., May 1 /PRNewswire/ -- Today the North American Deck and Railing Association (NADRA), the American Society of Home Inspectors (ASHI) and Simpson Strong-Tie kick off Deck Safety Month(R) with a nationwide campaign to educate homeowners about ensuring their decks are safe and secure. Nearly 85 percent of homes in the U.S. have a deck, balcony or patio. It is estimated that 20 million of these decks nationwide are in need of repair or rebuilding. "Deck failures like the tragic Chicago collapse of 2003, and the hundreds that go unreported each year, occur in an instant," said Michael Beaudry, executive vice president of NADRA. "We want to make sure consumers are aware of the necessity to maintain their decks, as well as the risks of having improperly built decks. It is critical that homeowners have the information and tools to regularly make sure that their decks are safe for use, no matter where they live." In the past ten years, there have been more than 800 reported injuries and 20 deaths as a result of deck collapses. In many cases the failing decks were built incorrectly, had not been properly maintained or were beyond their lifespan of approximately 10-15 years. "The reality of deck collapses is that many are not reported unless someone is injured or some legal action occurs," said Dr. Don Bender, a deck safety researcher and director of the Wood Materials and Engineering Laboratory at Washington State University. "It's important for homeowners to remember that a valid deck inspection requires a registered design professional. If homeowners have any questions about finding a professional in their area, they should consult with their local building department." The top ten U.S. cities with the highest percentage of homes with decks, as determined by the American Housing Survey for Metropolitan Areas, and that have reported one or more deck collapses in the last 10 years are: Atlanta, Birmingham, Kansas City, Seattle-Everett-Tacoma, Denver, Pittsburgh, St. Louis, Salt Lake City, Cincinnati and Miami-Ft. Lauderdale. For example, in 2006 four people in Atlanta were seriously injured in a second-story deck collapse when inspecting a home they were considering purchasing. In 2001, five people were injured and an 18-year old student attending Pacific Lutheran University in Tacoma, Wash., was killed during a college party at a student-rented house when a deck collapsed. "Reported deck failures often occur in cities with older housing stock, large populations or in areas located on or near the water," said Jeff Arnold, ASHI executive director. "We want to remind homeowners to make sure they work with their home inspector to take the appropriate steps to keep their friends and family safe." To evaluate the safety of their decks, homeowners should look for five warning signs that a deck is unsafe: loose connections (for example, a wobbly railing), missing connections (for example, the deck is just nailed, rather than bolted or screwed, to the side of the house), corrosion, rot and cracks. The two critical areas that typically contribute to a deck collapse are the railings and the deck's connection to the house. To ensure the structural safety of a deck, it should be built with a continuous load path -- a method of construction that creates a series of solid connections within the structure of the deck that transfers the load through its frame to the ground and adjacent support structure, commonly the house. If homeowners are unsure of the safety of their deck, experts suggest consulting with a registered design professional. "Most deck collapses are entirely avoidable," said Steve Pryor, P.E., S.E., building systems R&D manager for Simpson Strong-Tie. "Our goal is to help educate homeowners about proper deck design, construction and maintenance so they can stay safe while enjoying their decks this summer." In addition to its deck safety efforts with NADRA and ASHI, Simpson Strong-Tie is teaming with The Home Depot this May for deck safety workshops at stores throughout the U.S. The Home Depot and Simpson Strong-Tie also will host several events demonstrating safe deck construction techniques and the problems with a poorly constructed deck. Events will be held in these cities: Seattle - May 3rd; Atlanta - May 10th; Long Island (Jericho, NY) - May 17th; and Chicago - May 31st. To assist homeowners in evaluating the safety of their deck, Simpson Strong-Tie has developed a deck edition of its "5 Steps to a Safer and Stronger Home" and a "Deck Framing Connection Guide." The five steps include checking for the warning signs of an unsafe deck, knowing how weight and other forces affect the safety of a deck, ensuring the deck is built with a continuous load path, combating corrosion and knowing how to maintain a deck. The guide is designed to help those who are building a deck understand the critical areas of deck construction.
