Soft washing chemicals typically consist of a mix of sodium hypochlorite (or a chemical component of bleach) and water. While sodium hypochlorite and bleach are often thought to be the same thing, there is one small but key difference between the two: sodium hypochlorite comes in powdered rather than liquid form, which means that it’s also more concentrated and more effective from less product overall.

It may require stronger cleansers or chemicals, higher-pressure spray, or scrubbing to completely remove algae from a metal roof. Start with a mild cleanser; if that doesn’t work and you're comfortable doing so, use a stronger mix of ⅓ cup of laundry detergent, 1 quart of bleach, and 3 quarts of water to gently scrub the algae with a soft-bristled brush. If algae is present across large portions of your roof, doesn’t come off with gentle scrubbing and cleansers, or is in hard-to-reach areas, this may be a job better left to a pro.

Clay tile roofs require minimal maintenance, as they stand up very well to the elements and often won’t fade in direct sunlight. They also don’t need sealing. Concrete tiles are also relatively low maintenance, but you will need more maintenance than with clay. You’ll need to seal concrete every few years to improve water resistance, and the color will fade a bit more quickly than with clay.

It generally involves soft washing with eco-friendly detergents to remove contaminants, avoiding high-pressure methods that can damage materials.
