High temperatures and the hot sun can be extremely harmful to roofs. So homeowners in hot weather climates often opt for metal roofs that provide a more durable and efficient roofing solution.
In hot climates, your home’s roof has to endure extreme heat and vast amounts of direct sunlight. Heat and sun are the two things that break down roofs most quickly. Shingle and tile roofs can dry out, crack, curl and eventually disintegrate under all that intense heat.
This makes them more prone to leaks. And even the smallest flaw in a roof can make it more susceptible to wind damage, especially with hurricane season right around the corner.
Stronger, More Durable Protection
But metal roofs provide a stronger, more durable barrier between the sun’s rays and your home.
The sun also can affect color retention. Painted roofs can fade when exposed to the sun’s rays over time. Chalking also can occur.
Today’s homeowners with metal roofs should consider using paint products that have a high PVDF rating. These high-quality coatings are fade- and chalk resistant and outlast traditional roof paints. Their durability comes from PVDF resin, a type of metal fluorite that has a tight molecular structure to hold the pigment in place even under the harshest sunlight.
Roof paint with a high PVDf rating also is made with inorganic pigments, which have a reputation for being highly fade resistant.
Another benefit of metal roofs is their increased protection against fire. Other types of roofing materials can dry out over time, losing their fire resistance and increasing the risk of bursting into flame if they should come into contact with an incendiary such as lightning or sparks from a nearby power transformer.
But metal roofs create a lasting barrier against sparks, increasing the safety of your home.
Another consideration is weight. Metal roofs are often lighter than other roofing materials, so there is less risk of a cave-in should a fire break out inside your home.
