The process of affixing a metallic roofing system atop existing asphalt shingles involves several key considerations. This approach provides an alternative to complete shingle removal, potentially saving time and resources. The existing shingle layer acts as a substrate for the new metal roofing, offering a degree of insulation and noise reduction.
Opting for this installation method can lead to reduced landfill waste by foregoing shingle disposal. Furthermore, it may improve the structural integrity of the roof and enhance its longevity. Metal roofing offers superior resistance to weather elements, including wind, rain, and fire, resulting in long-term cost savings due to reduced maintenance and replacement needs. This technique has gained popularity as homeowners and contractors seek sustainable and durable roofing solutions.
