Image
Wrong – Gable end vents can circumvent soffit-to-ridge airflow and allow in wind-driven rain and wildfire embers
Image
Wrong – Garage door failure due to positive pressures from hurricane force winds.
Image
Wrong – If roof membrane is not fully adhered, it can flutter and fail due to negative pressure from wind above and positive pressure from air leakage through roof deck below
Image
Wrong – If the insulated sheathing will serve as an air barrier and drainage plane, any cuts and seams must be taped or sealed.
Image
Image
Wrong – Known as a Hugel Swale, organic matter like sticks and leaves break down into compost and fill the swale full. This limits the swale’s ability to filter rainwater.
Image
Wrong – Misalignment of the tie reduces the embedment and enables the brick veneer to be pulled away.
Image
Wrong – Piers set on individual footings with inadequate anchoring to the ground were twisted and toppled by a coastal storm surge, while those anchored in the concrete pad stayed upright.
Image
Wrong – Rain barrel installed without an overflow spout that terminates away from foundation
Image
Image
Wrong – Regular window glass is susceptible to breakage from the radiant heat of a wildfire; tempered and laminated glass are more resistant to breakage.
Image
Wrong – Roof underlayment is not fully adhered and roof deck seams are not sealed so roof is susceptible to high-wind events
Image
Wrong – The cabinets and drawers were not outfitted properly with mechanical or self-locking latches, causing them to swing open and spill their contents onto the floor.
Image
Wrong – The clips holding these metal roofing panels were set too far from the roof eave (above red line) and the panels lifted in strong winds
Image
Image
Image
Image
Wrong – The footers of this house were not deeper than the depth of scour during a flood, causing undermining of the foundation
Image
Wrong – The gable end wall failed because the rigid foam sheathing was not backed up by plywood or OSB.
Image
Wrong – The house was not bolted to the foundation and shifted off the foundation during an earthquake.
Image
Wrong – The metal panels covering this roof used snaplocks and concealed fasteners that gave way in high winds.
Image
Image
Wrong – The off-ridge roof vent on the right was poorly anchored and pulled off in high winds allowing water into the home.
Image
Wrong – The open overhang with exposed timbers and unscreened vent holes make this roof more susceptible to ignition.
Image
Wrong – The outer pane of this window broke under radiant exposure from a neighbor’s house that had ignited in a 2007 southern California wildfire.
Image
Wrong – The ridge flashing fasteners were placed too far apart and came loose in high winds.
Image
Wrong – The ridge flashing fasteners were placed too far apart and came loose in high winds.
Image
Wrong – The ridge flashing fasteners were placed too far apart and did not adequately hold the flashing in place
Image
Wrong – The rigid sheathing seams are not taped and the gaps could cause moisture problems
Image
Wrong – The roof sheathing was inadequately fastened and gave way causing the gable end wall to fail
Image
Wrong – The south side of this building in Arizona has very little architectural or landscape shading to block solar heat gain.
Image
Image
Wrong – The stud should not be positioned over seismic bolts then cut away, which reduces the stud’s load capacity; Shift the stud or specify stud and bolt positions in plans.
Image
Wrong – The underside of the first course of siding extends beyond the underlying sheathing leaving it vulnerable being pulled off by pressure from high winds.
Image
Wrong – The vinyl siding at this gable was installed over rigid foam instead of wood sheathing and neither had the structural strength to resist hurricane wind pressures.
Image
Image
Wrong – the water-resistant barrier is layered underneath the step flashing, which could allow water to get behind the step flashing and into the wall.
Image
Wrong – The water-resistant barrier is not complete and the holes and gaps could cause moisture problems
Image
Wrong – There are no gutters installed and there is not a proper gravel bed located at the foundation
Image
Wrong – There is not a self-sealing bituminous membrane installed at the valley of the roof
Image
Wrong – There is not a water-resistant barrier installed underneath the exterior finish of the walls
Image
Wrong – There is visible light around the door because no weather stripping has been installed.
Image
Wrong – These clay roof tiles were dislodged by high winds due to inadequate anchorage.
Image
Wrong – These four ties were never embedded into the mortar joint, allowing the brick wall to be pulled away from the sheathing.
Image
Wrong – This brick veneer failed in high winds (107 mph) because the ties pulled out of the substrate.
Image
Wrong – This deck is constructed with metal railings and the wooden supports are covered with fire-resistant stucco; however, the exposed wooden beams on the underside of the deck still pose a significant fire hazard.
Image
Wrong – This gable end wall failed because connectors were missing at points of support (blue circles) and the outlookers were not connected to the end truss (yellow circle)
Image
Wrong – This house under construction is lacking wall to truss bracing and the bottom chord of the scissor trusses is several feet above the top of the end wall top plate
Image
Wrong – This house was built on a shallow foundation instead of piers; the foundation was undermined by erosion from Hurricane Irma (Vilano Beach, FL)
Image
Wrong – This metal tie remained embedded in the mortar joint but the smooth-shank nail pulled out from the stud.
Image
Wrong – This multi family building appears to be done in traditional southwest architecture but the lack of useful overhangs, dark colored walls, and lack of tinting on windows will result in significant solar heat gain.
Image
Wrong – This roof has no sheathing, when the metal panels blew off there was no secondary protection
Image
Wrong – This roof membrane on a low slope roof is fluttering and may fail because it is not fully adhered and deck seams below are not sealed, allowing air to leak up into the assembly while the membrane is pulled up due to negative pressures from wind
Image
Wrong – This standard air vent has become blocked by flood debris and is located at the top of the foundation wall; it should not be used as a flood vent
Image
Wrong – This water heater was not braced; it fell during an earthquake and ruptured the gas line causing a house fire.
Image
Wrong – Tree branches close to the house are prone to spreading crown fires to the house; the tree should be trimmed so that branches are at least 10 feet back from the red dashed line indicating the deck railing of the house.
Image
Wrong – Wind-driven rain and wildfire embers can enter an attic through the soffit vents.
Image
Wrong – Window not protected and failed due to windborne debris in hurricane force winds.
Image
Wrong –The gate that was attached to the garage at the corner ignited and led the fire to the home, causing the damage seen here.
Image
Wrong-The home was pulled off its masonry pier foundation during a coastal flood due to inadequate pier-to-beam connections.
Image
Wrong-These masonry pier foundations were twisted and displaced by coastal storm surges in Long Beach, Mississippi.
Image
Wrong: Closed-cell spray foam roof insulation was not thick enough to meet IRC levels so the foam surface is colder than the dew point of the interior air and condensation formed on surface of the foam
Image
Wrong: Electrical components were installed near ground level and are likely to be flood damaged.
Image
Wrong: Single sided ventilation without at least two windows, wing walls, and predictable wind directions is ineffective for generating wind-driven crossflow.
Image
Wrong: The fiber-cement siding has cracked due to over-driven nails located too close to the edge of the board; these cracks provide a pathway for bulk water entry and offer little resistance to high winds.
