Local climate plays an important part in choosing the right roofing system for your home. In this blog, one of the leading local roofing and insulation companies Fortenberry Roofing shares the roofing systems ideal for warm climates.
Many people are under the impression that metal roofs in hot climates would be unbearably hot. But the truth is, metal keeps your home cool from three fronts:
Low Thermal Mass — Thanks to their natural conductivity, metal roofs do not retain heat. It cools down much faster than other roofing types, which means indoor cooling requirements become lower at sundown.
Airspace — Standard standing seam metal roofs have an airspace between the outer metal layer and the decking, which acts as a thermal barrier. This air cushion can cut cooling costs by as much as 20%.
Reflectivity — Copper and aluminum roofs are naturally reflective, while galvanized steel roofs can be painted a light color to enhance reflectivity. These “cool roofs” reflect UV rays and solar heat and helps make your home cooler during the summer season.
Tiles and Concrete
Tile roofing is one of the oldest roof replacement options available, having been around for hundreds of years. In addition to its exceptional durability and life span, tile has natural insulation. The curved profile creates airspace that lets the roof vent heat. Concrete is a more cost-effective option for homeowners on a budget. While it does not last as long as clay tiles, concrete tiles nevertheless have a longer than average life span, and comparable thermal performance.
Not many roofers offer thatched roofs as an option. But there is a reason why you will often find thatched roofs in tropical countries: because they can help keep your home cool. Straw thatch is a naturally insulating material that, if properly maintained, can be on par with asphalt shingle roofs in terms of life span and performance.
