Is it safe to collect rain water from an asphalt roof for your garden?

Collecting rainwater from an asphalt roof for garden use can be safe, but there are some considerations. Asphalt roofs may leach harmful chemicals, such as heavy metals or toxins, into the collected water, which can affect plant health and soil quality. It's important to ensure that the roof is in good condition and free from contaminants. If you're concerned, consider using a filtration system or collecting rainwater from a different, safer surface.
