5x5 foot piece of sheet metal
5x5 section of fire-resistant drywall
Electric drill with metal boring bit
Two cinder blocks
A gas grill on the back deck generates enough heat either open or closed to warp and, in extreme cases, melt vinyl siding on a home. At best, the heat will merely discolor the vinyl and cause it to buckle downward. The worst-case scenario is an expensive home repair involving the removal and replacement of large sections of siding. A few basic precautions will keep the house safe while the backyard chef concentrates on the barbecue.
Move the grill out from the side of the house on a deck or patio while cooking. The grill should not be used under eaves or awnings for risk of heat and fire causing overhead damage. As a general rule, if the grill is underneath any overhang attached to the house, the grill is too close to the house.
Video of the Day
Roll the grill to the edge of the deck or patio, or move the appliance into the backyard. It can be rolled back to its storage spot near the house when shut off and cooled.
Make a heat shield to protect the vinyl siding on rainy days when the grill absolutely must remain near the house. Set a 5x5 piece of sheet metal over the same size piece of fire-resistant drywall and drill holes through the metal into the drywall in the four corners.
Attach the metal to the drywall with screws.
Pull the grill away from the exterior wall and insert the heat shield between the grill and the wall, holding the shield upright between two cinder blocks.
Let the heat shield and the grill cool completely before moving.
Although a heat shield will provide protection for vinyl siding, it always is best to move a grill away from a residence for safety. Virtually all gas grills are equipped with wheels and handles, so there is no reason not to move the appliance away from the house while cooking.
