Preventing Home Damage from Wildfire

Thursday, June 24 2010


MOSCOW, Idaho – It may be wet and cool now, but summer will bring hot and dry conditions throughout the state.

With above normal amounts of precipitation this spring, the National Interagency Fire Center in Boise is forecasting a slow start to the 2010 Idaho fire season. But with little to no snowpack in the high elevations, July, August and September are predicted to have an above normal potential for wildfire.

"Anticipating wildfire is the first step to making your home and property as fire-safe as possible,” said Yvonne Barkley, University of Idaho associate extension forester.

New research shows that up to 85 percent of wildfire home ignitions are from flaming brands and embers that can fly in from as far away as five miles from the flaming front of a wildfire. This makes your home the largest and most vulnerable source of ignition on your property.

Barkley suggests these inexpensive things people can do now to increase their home’s fire-resistance:

• Remove all debris from gutters, overhangs, room additions and bay windows. Pay attention to areas such as corners and under stairs, as well as under decks, porches, carports and around fences.

• Box in eaves, fascias, soffits and vents, or enclose them with metal screens. Cover vent openings with metal screens to prevent firebrands or other flammable objects larger than 1/8” from entering the home.

• Install spark arresters on chimneys.

• Reconsider outdoor furniture and accessories: many of these items are common sources of ignition. Replace wood or wicker tables and chairs with ones made from metal and glass.

• Cushions, umbrellas, furniture covers, door mats, planters and window boxes, as well as boats, campers and other recreational equipment, are all places where embers can collect, smolder and ignite well after the fire has passed. Have an enclosed space to store these items or be able to move them away from the home in the event of a blaze.

• Indentify areas where combustible materials meet, such as where a wooden fence is attached to wooden stairs that lead to a wooden deck. Separate these areas with a span of non-flammable material.

Barkley also suggests these long-term retrofitting activities:

• Roofing materials have flammability ratings, from Class A – able to withstand severe exposure to fire, like metal roofs, to Class C – able to withstand light exposure to fire, like asphalt shingles. Wood shake roofs are not rated and, in many cases, offer almost certain ignition of the home.

• Use of fire-resistant exteriors such as cement, plaster, stucco, brick and masonry provides greater levels of protection to the home than vinyl siding.

• Use of double-paned or tempered glass can help reduce the risk of interior ignitions from heating by providing an added layer of protection.

• Screens should have metal frames as well as metal, not plastic, mesh.

In addition, the complete guide, "Protecting and Landscaping Homes in the Wildland/Urban Interface," is available from the University of Idaho. It provides insight to understanding wildfire and how homes are destroyed, as well as tips to minimize home ignition potential. The publication costs $4 and is available by contacting Agricultural Publications, University of Idaho, P.O. Box 442240, Moscow, Idaho, 83844-2240, (208) 885-7982 or by e-mailing agpubs@uidaho.edu.
