Metal roofing has grown in popularity over the last decade, but many homeowners still have misunderstandings about its benefits. Aside from its sleek appearance and reputation for longevity, metal roofing has many lesser-known benefits—and a few considerations—that should be understood before installation.
- It lasts much longer than standard roofing. While asphalt shingles normally last 15-30 years, certain metal roofing systems can last 40-70 years if installed and maintained properly. Materials like steel, aluminum, and copper are resistant to cracking, shrinking, and eroding, which are common problems with other forms of roofing. For homeowners who intend to stay in their homes for an extended period, this longevity can dramatically lower lifetime roofing expenditures.
- Metal roofs are typically lighter than asphalt shingles or clay tiles. As a result, metal roofs can often be put over existing roofing materials without requiring significant structural reinforcing. This can reduce installation time and disposal expenses.
- Metal roofing systems often include reflective surfaces that reflect solar radiation away from the building, providing significant energy efficiency benefits. This can help reduce cooling expenses during the warmer months by keeping attics and upper levels cool.
- Noise concerns are generally overstated. Some homeowners worry that metal roofs will be louder during rain or hail. Most current systems, however, use aluminum panels over solid decking with insulation and underlayment. These layers absorb sound, which means the noise level is often equivalent to other roofing types.
- Metal roofing is recyclable. Unlike asphalt shingles, which usually wind up in landfills, metal roofing materials are typically constructed from recycled content and may be entirely recycled at the end of their useful life.
