Is Bleach Safe For Your Roof?

If you are considering power washing your roof and want to use bleach to kill mold and algae, you should think twice. Although bleach can be effective in killing these organisms, it also comes with a number of risks. Bleach is highly corrosive and can damage the shingles on your roof, causing them to become brittle and deteriorate faster than normal. Additionally, the bleach can run off into the soil around your house and potentially contaminate drinking water sources.

There are alternative methods for killing mold and algae on your roof that don’t involve using harsh chemicals like bleach. A mixture of warm water and dish soap is a good option for cleaning mildew off asphalt shingles without damaging them. For tougher stains caused by moss or lichen, you can try a mixture of detergent, trisodium phosphate (TSP) and water instead of bleach.

These alternatives are much safer for your roof’s shingles as well as the environment around your home. In conclusion, using bleach when power washing your roof may seem like an easy solution but it is not recommended due to its corrosive nature and potential environmental issues it can cause.

If you need to clean mold or algae from your roof, consider using an alternative cleaning mixture instead that won’t damage the shingles or contaminate surrounding areas with toxic chemicals. Contact Kings Way Paver Sealing & Pressure Washing today.
