Image
Winter storms can cause power outages while prolonged winter weather can take a toll on building structures
Image
Wire hardware mesh is fastened with a staple gun and screws to the wall to prevent pests from entering the building through small holes and cracks
Image
With fiber cement siding, face nail rather than blind nail where the design wind speed is ≥100 mph.
Image
With fiber cement siding, place blind nails 3/4 to 1 inch from top edge and > 3/8 inch in from butt ends.
Image
With modern low-E storm windows, manufacturers offer many frame colors and the option for custom color matching
Image
With the nailed block method, wood blocks are attached to the sill plate and the cripple wall plywood is attached to the block to provide shear strength for correctly bracing a cripple wall in a seismic retrofit

Wood siding installation details to improve resistance to wind-driven rain at corners.
Image
Wrong - Airborne embers can float into holes in damaged vent screens and ignite flammable items in the house or accumulated debris in the vent.
Image
Wrong - An open eave with no soffit covering can trap rising hot air and embers from a wildfire.
Image
Wrong - An unbraced water heater in this home fell during an earthquake; the resulting fire destroyed the home.
Image
Wrong - Debris in these open gutters can ignite from wind-borne embers and lead to ignition of the roof or fascia board; use leaf screens to keep debris out of gutters in wildfire-prone areas.
Image
Image
Wrong - During high winds air entered the home elsewhere and pushed out the door which was inadequately anchored to the wall.
Image
Wrong - Framing a dormer using only toe nailing and end nailing is not acceptable in areas subjected to high winds, hurricanes, or earthquakes.
Image
Wrong - Glazing failed due to windborne debris during a hurricane.
Image
Wrong - If the soffit is applied directly to the rafter eave, it forms a sloping soffit, which creates a pocket that can trap hot air and embers from a wildfire.
Image
Wrong - In floodplains, the interior grade elevation should be equal to or higher than the exterior grade as shown on right.
Image
Wrong - Leaks in the roof sheathing can allow water to get in and wet the drywall, providing fertile ground for mold.
Image
Wrong - Mold can spread rapidly in flood damaged homes if materials aren't dried quickly.
Image
Wrong - Negative pressure from hurricane winds caused garage door to collapse inward.
Image
Wrong - Roof deck sheathing nails missed the trusses, potentially weakening the roof in high winds.
Image
Image
Wrong - Roofs with complex geometries are more susceptible to ignition during a wildfire because they offer more places for burning embers to become lodged.
Image
Image
Wrong - The pile foundation of this home nearly collapsed from coastal storm surges because the piles were not embedded deeply enough in the ground.
Image
Wrong - The window lying on the ground was protected by a shutter but the shutter was attached to the window frame, rather than directly to the wall framing.
Image
Wrong - this building provides no overhangs, minimal window shading, and clear window glass resulting in high solar heat gain.
Image
Wrong - This concrete roof was not adequately attached and reinforced and failed in high winds.
Image
Wrong - This roof failed in high winds due to lack of metal attachments to the framing.
Image
Wrong - This surface downspout run-out is directed toward the foundation instead of away from it.
Image
Image
Wrong - Utility trim was substituted for the starter strip and the bottom lock was cut off this vinyl siding so the siding pulled loose under wind pressure.
Image
Wrong - When the lower break-away wall gave way in coastal flooding it peeled some of the EIFS siding off with it because there was no suitable break in the siding to allow it to detach cleanly.
Image
Image
Wrong – Airborne embers can float into holes in damaged vent screens and ignite flammable items in the house or accumulated debris in the vent.
Image
Wrong – An open and/or sloped soffit can trap heat and burning embers as a wildfire approaches, increasing the risk of ignition of the structure.
Image
Wrong – Combustible debris under this deck ignited and led to the destruction of the deck.
Image
Image
Wrong – Conventional wood deck risks ignition from embers falling on the surface or from unmaintained vegetation burning below.
Image
Wrong – Drain pipe has been cut and foundation penetration has not been properly sealed
Image
Image
Wrong – Either this tape was not pressed down firmly or the surface was wet or dirty so the tape is not sticking properly even during construction.
Image
Wrong – For proper detailing of vinyl around windows and other obstacles, use utility trim, punch snaplocks into siding, and do not overlap directly beneath a window.
