Homeowners should consider installing metal roofs to protect their homes during the upcoming tornado season in 2021. The Tornado Alley states were historically Oklahoma, Colorado, Texas and Kansas, but severe storms have spread beyond these states in recent years. Between April and May of 2020, a rapid increase in tornadoes is expected, causing severe damage and destruction.
If you live in a tornado-prone area, now is the time to upgrade your roof to a metal roof. The following are the reasons.
Tornadoes and severe thunderstorms are both possible outcomes.A tornado can be launched from severe thunderstorms, not to mention the hail and wind damage that accompany these storms.
When it comes to tornadoes there are three main components: In the atmosphere, there is a lot of moisture. As a result, warm, moist air near the ground alternates with cooler, dry air higher in the atmosphere. Roofing companies will help you decide your next step the best.
For a storm to spin, wind shear, or the change in wind speed and direction with height, is essential. Thunderstorms can’t develop further without that rotation.
According to reports from the National Severe Storms Laboratory, severe thunderstorms without wind shear can generate straight-line winds of up to 100 mph, with hail impact and damage pathways broadening for hundreds of miles. Half of all negative and destructive reports in the lower 48 states are attributed to these storms.
Metal roofs and traditional roofing materials. A traditional roof’s wind uplift resistance and shear strength are lacking. A metal Roofing product’s warranty covers winds up to 120 mph, and it has been lab tested at twice that speed. Roofs made with interlocking system are also more secure.
Roofs covered with asphalt shingles are more susceptible to wind uplift because they are prone to cupping, splitting, warping and delamination over time. For this reason, clay tiles and wood shakes aren’t covered by wind warranties. Roofs with Tier 1 Contracting metal roofs are less prone to cracking and splitting, which makes them more vulnerable to damage from wind, hail, and rain.
Hail barrages from the same severe thunderstorms that produce tornadoes can also cause damage to a roof. Hail with a diameter of up to 2.5 inches is warranted by credible roofing companies. They are so susceptible to impact fracture that they are not even rated for it.
As a result of the parallel “side forces” and stresses of high winds in tornado regions, as well as the vibrations of tremors and structural stresses in earthquake zones, a roof’s shear strength is determined. Our roofs add shear strength to roof decks in earthquake and hurricane zones. Shear strength is not increased by traditional roofing materials. The metal roofs weigh just 1.4 to 1.6 pounds per square foot, compared to clay tile at 18,000 to 45,000 pounds and architecture and design shingles at 7,500 to 12,000 pounds.
Roofing companies in Oklahoma know how tornadoes can damage your home and cause a lot of mess. Come to Tier 1 Contracting if you wish to provide added protection to your roof. Install metal roof before it is too late.
