Why are metal roofs better?

• Durable, Long-Lasting: Asphalt shingle roofing is the more common and traditional choice for homeowners. However, we are all noticing a metal roof has proven to have more durability, giving it a longer lifespan.  In fact, a lifespan that extends for 60 years or more when coated or more than 100 years if it is a copper or zinc metal roof. A metal roof can withstand hail, ice, rain, snow, and UV rays longer than an asphalt roof. 
• Fungus, Moss Proof: Unlike asphalt, a metal roof is 100% resistant to fungus, mildew, mold, and moss. 
• Critter, Insect Proof: Where critters, insects, and rodents can get through an asphalt roof, they can’t with a metal roof!
• Fire Resistant: A metal roof is fire-retardant with most high-end metal roofs rated Class A fire retardancy. If your home is in an area that is a wildfire prone zone, your insurance company will love a metal roof, even enough to give you some discount for that upgrade, as much as 35% with some companies. 
• Sustainability: A metal roof is a sustainable material, lasting up to three times longer than an asphalt roof. This means it won’t need replacing as often and when it does need replace, metal is recyclable. The metal used on a metal roof is 30% recycled material too! 
• Withstand Hail: Most metal roofs are rated with a class-4 hail impact-rating against hail-stone up to 2 inch diameter. Some metal roof manufacturers offer warranty to their hail impact rating. 

What are the disadvantages of a metal roof?

Even with these advantages and benefits, a metal roof has one big disadvantage: the cost of installing the metal roof. The upfront cost is a lot more than an asphalt roof, but once it is installed, with proper maintenance and upkeep, you won’t be replacing it again in 20-25 years. 

Do metal roofs make house hotter?

Nope, that is a myth and probably because metal roofing is misunderstood, or bit understood at all. A resin coated metal roof coated can achieve solar reflectance index over 70 compared to the solar reflectance index of 25 for asphalt cool roofs. Because it reflects most of solar radiance, it helps keep the surface cooler and limit how much heat is absorbed and transfers inside your home. 

An additional point here is the thermal emissivity that a metal roof offers. The day’s solar radiant heat is released into the atmosphere quickly with the sunsetting. A metal roof will cool down faster than an asphalt roof.
