Tips & Warnings
Oxygen bleach can be used as a nontoxic alternative to chlorine bleach. It is more expensive than chlorine bleach but it won’t harm plants around the foundation or discolor wood shakes. Mix the oxygen bleach powder with water according to package directions and use in place of the diluted chlorine bleach solution.
Be very mindful when working on a roof. Avoid wearing shoes with slick bottoms and be especially careful when walking on wet shingles.
Chlorine bleach can discolor wood roofing shakes. If you have wood shakes on your roof, use oxygen bleach instead.
