One of summer's many lightning storms can start a fire, and with no one to call 911 it can take out a whole house. The best defense, says TOH general contractor Tom Silva, is lightning rods. "This is not by any means a homeowner job," he warns. "You need a pro to install them." Any highly placed metal protrusion on your house should be grounded, in fact, including weather vanes and satellite dishes.
Don't overlook the health of your wiring, as well. Curtis Niles Sr. of Armored Home Inspections in Upper Darby, Pennsylvania, and President of the National Association of Home Inspectors, advises homeowners to keep up with maintenance. "Wiring is the last thing on a homeowner's mind, but I've seen exterior service cables in poor condition all too often." he says. "If there's short or a spark in the line, a fire can start, and you won't be there to put it out."
