Do you live in tornado alley? This is the area of the U.S. unofficially defined as the section between the Rocky Mountains and the Appalachian Mountains. There is no state in the country completely exempt from tornado activity but they are most frequent in the states that rest between these two mountain ranges. Texas gets the most tornadoes, followed by Kansas and Oklahoma. Florida also gets its share of tornado's but not with the same fury as the ones that happen in the plains.
Around 90% of tornado's happen in Tornado Alley because of the cold, fry air from Canada and the Rocky Mountains bumping into the moist, warm air from the Gulf of Mexico and the dry, hot air from the Sonoran desert. The resulting atmospheric instability is what instigates the intense weather patterns.
The most aggressive tornado's with the longest tracks erupt in the lower Mississippi Valley and the upper Tennessee valley. This section has been nicknamed "Dixie Alley". There are other smaller alleys in the country, but the result is all the same - if one touches you roof it had better be secure to resist being torn off by the wind and pressure. Old, deteriorating shingles, loose tiles or metal sheets and wood shakes popping off roofing nails are no match for the force of nature.
They vary in the damage they do despite where they happen, how big they are or their shape. Larger tornado's with longer tracks are predominantly stronger. Hopefully if a tornado passes through your neighborhood, you'll need roof repair since it will indicate your house is still standing.
