Yes, aluminum strips can be used for roofing in hot climates. Aluminum is a lightweight, durable, and corrosion-resistant material that can withstand high temperatures without degrading. It reflects heat, reducing the amount of heat absorbed by the roof, which can help keep the interior of a building cooler. Additionally, aluminum's resistance to rust and corrosion makes it an ideal choice for climates with high humidity or where there is a risk of saltwater corrosion. However, it's important to ensure proper installation and ventilation to maximize its performance and longevity.
