Admitted to the Union in the year 1819, is the 22nd state of the United States. It is home to roughly 5.05 million people, and ranks as the 30th largest state, occupying an area of 135,765 km². It is one of 5 ‘Gulf States,’ with a 53 miles long coastline that meets the Gulf of Mexico. The state’s climate is classified as humid subtropical, and is characterized by hot and humid summers, and cooler winters. Severity in weather is common - especially in peak summer and winter time. As with other Gulf States, Alabama is prone to storms and hurricanes. It has been hit by several major natural disasters, which includes (but is not limited to) Hurricanes Frederic (1979) and Ivan (2004), the Super Tornado Outbreaks of April 1974 and April 2011. In fact, it is one of the few places one earth which faces a secondary tornado season in November and December. Droughts, however, rarely occur here.
Given the state’s vulnerability to natural events and general weather extremities, roofing systems in Alabama need to be resilient enough to withstand fluctuations that occur throughout the year and shelter homes. Some of the most common type of roofs in Alabama include metal roofs (which offer great protection against rain and moisture, and prevents algae and mold formation), slate roofs (known for their durability, thermal properties and aesthetic appeal), concrete tile roofs (which qualify as a great low-cost alternative with thermal properties similar to slate), rubber membrane roofs (which is often used as an extra layer of protection and works on both flat and sloped roofs), green roofs (made up of plants suspended on a waterproof membrane, working best in wet and warm areas), Built up roofing (for establishments needing a more robust system, and radiant roof barriers (made up of reflective materials which bounces heat off). Roofs may be flat or sloping.
