Metal roofing is especially important and enjoys strong popularity in warm climates because towering temperatures and intense sun are especially damaging to roofing materials prompting homeowners to seek out more durable, long-lasting, and energy proficient alternatives such as metal.
So, therefore, let’s explore one reason among many as to why having a metal roof can be valuable to you, and also why it is extremely popular in hot climates:
One of the main reasons metal roofing works so well is because it is durable. In all climates, roofs are often subject to severe winds and damaging rains; but in hot climates, it also endures intense heat and an extremely high amount of sunlight. Most of the time, heat and sun cause most roofing materials to break down rapidly—they dry out, fissure, coil, and crumble. As this happens, their lives are shortened and they become more susceptible to leaks and wind damage.
But metal doesn’t do that—it is virtually impermeable to heat and sun.
A special attribute in regards to metal roofing being so durable in hot climates is color retention. Many older paint technologies perform well but the sun is their enemy. Landowners who are seeking a painted metal roof can find products which have PVDF coatings. These high quality coatings, known often though not exclusively by the trade names of Kynar 500 and Hylar 5000, are highly fade and chalk resistant and out-perform other paint systems. Their durability comes from the PVDF resin which, based upon the mineral fluorite, creates a very tight molecular structure to hold the pigment in place, not allowing it to chalk. Additionally, these coatings use only inorganic pigments for their color–pigments known for being highly fade resistant.
So, one of the main reasons why you should consider a metal roof if you live in a warm climate is because it is durable and it will retain the color in which you have had it constructed with.
