Metal roofs are often misunderstood, and one of the biggest misconceptions surrounding them is they make houses more uncomfortable in the summer. This notion is unfounded. In fact, the primary reason metal roofing systems are hot right now is they are being marketed as “cool” and are good at increasing energy efficiency.
Reflecting the Sun
Painted or not, metal deflects more solar heat than its more popular counterparts. Its thermal properties reach another level when coated with a reflective finish, which contains cool pigments that significantly contribute to solar reflectance.
You may still need to run your AC from time to time with a metal roof, but you can expect to see your utility bills to go down. Metal’s energy efficiency can save you on cooling by up to 40%.
Re-Emitting Absorbed Heat
Excellent thermal emittance is another quality that makes metal roofing green. It can re-emit up to 90% of the solar heat it absorbs. By storing up to just 10% of the infrared radiation it can’t reflect, you will not feel the intensity of the summer as much.
Keeping the Air Below It Moving
Be it a metal or rubber roof, adequate ventilation is key to keep the surface temperature low. Hiring an experienced roofer like Solid State Construction will ensure that your roofing system can breathe properly. A balanced system of intake and exhaust vents is essential to regulate the attic climate and to keep the downstairs spaces naturally cooler.
