Which type of tarps are used for covering roofs?

Polyethylene tarps are commonly used for covering roofs due to their waterproof and UV-resistant properties, making them effective for temporary weather protection. They are lightweight yet durable, providing a reliable barrier against rain, snow, and debris. Additionally, canvas tarps can also be used for roofs, offering breathability and sturdiness, though they are typically heavier and less water-resistant than polyethylene options.
