Yes, aluminum strips can be used for roofing in cold climates. Aluminum is a durable and lightweight material that is resistant to corrosion and weathering, making it suitable for various climates, including cold ones. It doesn't rust and can withstand heavy snow loads. However, it's important to consider the thermal properties of aluminum, as it conducts heat and cold efficiently, which may necessitate additional insulation to maintain the desired indoor temperature. Additionally, proper installation and underlayment are crucial to prevent moisture and heat loss.
