Make your home fire-resistant

This is a beautiful time of year. The mountains and foothills are awash in green grasses and vegetation and for a brief moment it feels more like the lush Northwest than the arid Great Basin.

But already the desert heat is turning the first greens of spring to the dry yellows of summer, and we find ourselves approaching another fire season. There are steps you can take when remodeling or building anew to help guard the exterior of your home against marauding flames from a wildfire or neighboring house fire.

The primary ignition sources for exterior fires are flames, radiant heat and airborne firebrands. The most vulnerable areas of your home's exterior are the roof, soffits and windows. Though beautiful, wood shingle roofs are especially hazardous. They make all-too-productive tinder for fire, and once aflame, airborne shingles can be a hazard to surrounding structures. Instead, consider using more fire-resistant materials such as Class A asphalt or fiberglass shingles, metal roofing material, terra cotta tiles or lightweight concrete composite materials.

Keep your roof free of leaves and debris that may accumulate in valleys or gutters and become fuel for a fire. Chimneys and stovepipes should be covered with a nonflammable screen, as should attic and underfloor vents, to prevent sparks from entering your home.

A soffit is the horizontal part of your roof that overhangs the exterior walls. Vinyl is often used in this area because it is relatively inexpensive and maintenance-free. However, vinyl will quickly melt and allow fire to penetrate into your attic or roof. For better fire protection, soffits should be made of a noncombustible material or a minimum of 1/2-inch thick wood sheathing.

Windows are a vulnerable point in the envelope of your home. Heat from a fire will cause glass to fracture in just minutes. Double-paned glass and tempered glass give more protection than single-paned. Smaller panes will hold up better than larger ones. You can also add operable, nonflammable shutters for extra protection.

For exterior cladding materials, brick, stucco and man-made products, such as cement fiber board, are better at surviving flames than real wood. Foundations are usually built of fire-resistant concrete or masonry block. The further a foundation extends above the vegetation, the more protection you will have from a spreading ground fire. Also consider using metal doors instead of wood ones.
