Resale value of metal roofed houses will be higher than others. Buyers will appreciate the aesthetics, reliability, and protection the metal roof provides, and will show that appreciation in their opening offer. Add to that the fact your buyer may be purposefully seeking out a metal roof will give you significant bargaining power: your home may sell faster or for more than even you were hoping!
Protection equals savings on insurance. Most metal roofs systems are designed to withstand UL 2218 Impact Resistance testing at Class IV (the most extreme class). With this, a home-owners (especially in hail prone states like the mid-west) can be eligible for insurance premium discounts. That makes sense, since you will be a ‘more insurable’ customer with that protection that makes you that less prone to total roof damage! The U.S. Energy Policy Act of 2005 allows for a tax credit for homeowners who install qualified energy-efficient improvements to an existing home, including metal roofs that meet the Energy Star program requirements.
The phrase “Metal is much more durable” is accepted as fact.
An estimated 20 billion pounds of asphalt shingles are sent to landfills in the U.S. alone every year, an unfathomable number and amount of waste. That number is not surprising seeing as how the NAHB found the average asphalt shingle roof lasts just twenty years. Just to think about how much waste could be saved every year makes stainless metal that much more reasonable- and desirable! Better still, metal can be laid over existing shingle, making removal and landfill fees unnecessary. And if a metal roof is ever removed (or individually replaced panels) can be recycled domestically. Aluminum metal roofs are manufactured with up to 95% recycled post-consumer metals.
According to the American Iron and Steel Institute, steel is the best choice for ‘green’ building where the goal is to reduce chemical substances being immune to rot and insects!
Saving money on electricity is also a perk of having a metal roof, having high thermal emittance (to cool down rapidly at night) and higher reflectivity; modern pigments in metals can be both dark and highly reflective of thermal radiation (sunlight). This means your attic will both be slower to heat up in the summer days and quicker to cool down in the summer evenings.
Wikipedia agrees: “For building products, thermal emittance measurements are taken for wavelengths in the infrared. Determining the thermal emittance and solar reflectance of building materials, especially roofing materials, can be very useful for reducing heating and cooling energy costs in buildings. Combined index Solar Reflectance Index (SRI) is often used to determine the overall ability to reflect solar heat and release thermal heat. A roofing surface with high solar reflectance and high thermal emittance will reflect solar heat and release absorbed heat readily. High thermal emittance material radiates thermal heat back into the atmosphere more readily than one with a low thermal emittance.”
To save the very most on cooling, create an air gap over your existing roof that shields your attic from the extreme heat daily. With a new metal roof and air gap you can further those cooling savings to their logical maximum!
All this durability and protection lends itself to one more perk: lower maintenance. A good metal roof simply won’t crack, peel, rot, split, lose impact resistance or lose sections from wind. Whereas with shingle roofs it is exceedingly urgent to catch leaks and problems right away before the wood of the structure and roof begins to literally rot away, with metal roofs, your anxiety will be lower. Perhaps you, an able bodied homeowner can perform inspections yourself once a year, clearing the roof of accumulated leaves or other debris and checking roof top ancillaries and air conditioners to ensure that they are properly drained and supported. The basics recommended for all roofs regardless of material!
