Roof Cleaning questions, answered by experts

You should not clean roof shingles if the roof has damage like missing shingles or low spots where water may accumulate. You should focus on repairing the roof before any cleaning process occurs. If you notice roof damage as you’re climbing on the roof to clean it, stop immediately. Call a roofing pro to make repairs. Cleaning a roof that has damage could lead to pooling water or water damage to the roof decking. The roof cleaning process removes mold and mildew, making the roof look better. It is not going to fix physical damage, though.

If you wish to forego painting your shingles but still want to give them a fresh look, a deep cleaning is the first step. Clean off any debris from your roof and gutters, and then power wash your shingles to get grime and algae off. To take things one step further, you might even consider installing new gutters to give your home a bright new look.

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.

No, asphalt shingles should not be power washed. A power washer or pressure washer is too strong to use on asphalt shingles and will loosen the adhesive holding them to your roof, causing them to fall off. It’s best to hire a local roof cleaner to clean those shingles safely and without damaging them. 

Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and roof flashing. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.
