Are there any safety concerns with using aluminum strips for roofing or siding?

While aluminum strips are generally safe for roofing and siding, there are a few concerns to consider. Aluminum can expand and contract with temperature changes, which may lead to buckling or warping over time. Additionally, it is a good conductor of heat and electricity, so it may not provide the best insulation or protection against lightning strikes. Aluminum is also prone to denting and can be noisy in heavy rain or hail. However, it is lightweight, durable, and resistant to corrosion, making it a popular choice for many homeowners. Proper installation and maintenance are crucial to minimize these risks.
