It is common for homeowners to overlook (or simply forget) their roof and siding maintenance agendas. But keeping the roof and siding clean helps them perform better and last for years to come. A common method used to clean these areas involves bleach. Bleach is a chemically-strong product that should only be used with extreme caution and care. As for applying it to your roofing and siding, you need to know who to do so without causing any serious damage.

Continue reading for recommended instructions for cleaning roofs and siding with safe bleach solution.

Siding

If you choose to clean your siding on your own, be sure you have experience using pressure washing machines and ladders. Otherwise, there could be structural damage and safety risks involved. If you are inexperienced at either of these, it is recommended to hire a professional company to clean your siding.

To clean residential siding with bleach, you will need water, powdered laundry detergent, a soft-bristled brush (do not use steel wool or anything too harsh), a pressure washer, a large bucket, a ladder, and a trisodium phosphate cleaner (try Arm & Hammer® Super Washing Soda).

Cover any plants, flowers, and garden beds to protect them from bleach water runoff. Then combine 1 gallon of water, 1/3 cup of powdered laundry detergent, and 2/3 teaspoon of trisodium phosphate together in a large bucket.

Dip your brush into the solution, scrub it into the siding, and then rinse it off. Be sure to start from the bottom and work your way up while rinsing off the solution with your pressure washer as you go. Work in small sections so that you can fully rinse the solution off after it is scrubbed into the siding.

If you have mold or dark stains, consider following up by using a solution made from 1 cup of oxygenated bleach and 1 gallon of water.
