Many people overlook the hotter months of Florida when selecting roofing materials for a building. Metal roofs can withstand harsh weather conditions, including snow, rain, and wind. Metal roofs, when properly insulated, can also help to keep heat in a building. What about hot weather conditions?
Metal Roofing vs Shingles Roofing in Hot Climates
Metal roofs are more durable and energy-efficient than shingles, especially in hot weather. Compare these two roofing materials on the basis of three factors: durability, energy efficiency, and heat reflection.
Zero Heat Reflection
The biggest disadvantage of shingles, however, is that they absorb rather than reflect heat. Asphalt shingles in particular absorb a large amount of heat from the outside. The heat is then transferred to the building below and raises the temperature. The heat transfer from a shingle roofing system to the building below may raise the temperature of the interior by up to 25 degrees.
How Hot Does a Metal Roof Get in the Summer?
In warm climates, the surface temperature of metal roofing can be very high but it is not as hot as asphalt shingles. Unpainted metal roofs can reach temperatures of up to 140 degrees in summer. Black asphalt shingles, on the other hand, can reach up to 168. Metal roofs painted with heat-reflective paint can feel as much as 42% cooler than metal that is not coated. Metal roofs are not able to transfer heat from the roof below. Metal roofs can help keep your building cool in extreme heat with the right insulation and panel coating.
