Any porch, balcony or overhang with exposed space underneath is fuel for an approaching fire.
Overhangs ignite easily by flying embers and by the heat and fire that gets trapped underneath. If vegetation is allowed to grow underneath or if the space is used for storage, the hazard is increased significantly.
Clear leaves, trash and other combustible materials away from underneath sun decks and porches. Extend 1/2-inch mesh screen from all overhangs down to the ground. Enclose wooden stilts with noncombustible material such as concrete, brick, rock, stucco or metal. Use non-combustible patio furniture and covers.
If you’re planning a porch or sun deck, use non-combustible or fire-resistant materials. If possible, build the structure to the ground so that there is no space underneath.
