Metal roofing offers the highest longevity of any flat roofing system available. That being said, you can expect to get up to 50 or more years out of a metal roofing system. Learn more about the lifespan of other commercial roofs here
Metal is an incredibly strong material, so it’s not hard to imagine the benefits of having a metal roofing system. For starters, metal is naturally resistant to punctures, hail, and fire which is a concern for those living in places with extreme weather. In fact, metal roofing’s main competition in terms of lifespan is EPDM roofing (which can last up to 50 years), yet metal roofing is much more secure with rain, pooling water, oils, and chemicals than EPDM is, although both are water resistant. The fact is that water can get in between seams of EPDM near the end of its life or if it wasn’t properly installed. On the other hand, metal roofs that are 30-50 years old still stand strong with no signs of integrity issues when they are properly installed. This is why it’s imperative that you work with a reliable commercial roofing contractor like Watermark Exteriors to ensure proper installation.
The cost of metal roofing systems varies depending on the type of metal used. For example, aluminum shingles cost between $9 and $16 per square foot taking into account both material and installation cost, corrugated metal $5.50 to $11.50, standing seam panels $10 to $18, galvanized steel shingles and tiles $10 per square foot, tin $10 to $19, zinc $18 to $28 per square foot, and copper tiles $21 to $40 per square foot.
