While metal roofing has recently surged in popularity amongst homeowners, it has dominated the industrial sector for centuries. Factories, barns, military barracks, warehouses and other industrial buildings have benefitted from the durability, longevity, high roi and low-maintenance characteristics that only a metal roof can provide. Historically, metal roofing wasn’t embraced by the residential sector as it was considered “too industrial looking” by most homeowners. This changed when the decraspray company developed an emulsion coating made from road tar and stone chips during world war ii. Designed to camouflage the highly reflective metal roofs of military buildings in wartime england, the stone-coating formula was developed to provide protection from german air raids.
Metal Roofing Lasts A Long Time
Perhaps the most critical advantage metal roofing offers homeowners is longevity. Roofing can often be one of the most expensive purchases a homeowner will make after the purchase of the home itself. Between the cost of roof replacement and the obvious disruption, it comes as no surprise that most homeowners make it a priority to minimize the number of times they need to replace their roof. When comparing longevity between metal roofing and shingles, there really is no contest. Typical asphalt shingles have an average lifespan of 15 to 20 years. Metal roofing has an average lifespan of 50+ years.
Nothing lasts forever, but the right choice of metal roofing can endure for many lifetimes. Just take a look at the roofs topping countless famed cathedrals and castles in europe and historic buildings like thomas jefferson's monticello or the washington monument - all examples of metal roofs lasting centuries. If priorities for your roof include low maintenance and longevity, metal should be one of your first choices.
Asphalt is a petroleum product, so it begins to deteriorate from heat and weather damage from the moment it’s installed. That’s why a composition shingle roof typically has to be replaced every 10 to 20 years, especially when it’s your home’s first line of defense against texas’ scorching heat and violent hail storms. By contrast, there are so many ways asphalt shingles deteriorate over time: lifting, curling, blistering from heat, balding (aka losing granules), cracking, creasing, tearing, cupping, buckling, separating, splitting, and a whole lot more synonyms for decomposing. But metal roofing has an expected lifespan of 40 to 70 years – or longer.
