Wind damage to buildings is not always readily apparent. For this reason, examine all farm buildings for hidden damage after a severe windstorm or tornado. Undetected damage could weaken a structure, creating possible hazards. Prompt repair is usually less expensive in the long run.
ROOFInspect the foundation. The plate should not be separated from the studding where the foundation meets the walls. On block foundations, inspect mortar joints to make sure the block with the plate bolt in it hasn't separated from the wall. On stone or concrete foundations, check to see that the plate bolts have not worked loose.
SILOMake sure the silo is still plumb. Look for loose hoops. Inspect the roof to be sure it remains fastened to the silo. Inspect the base of metal silos inside and outside for hairline cracks. If there is rust around the base, remove it with a wire brush. Then check for cracks and apply a rust preventive paint. Look for new cracks in the plaster of empty concrete stave silos.
INTERIORInspect the interior of buildings for structural damage. Using a good light, check the framing. Look for ridge separation, loose knee braces and loose rafters where the rafters join the walls.
