Bleach is a topical cleaner that isn’t intended to scrub deep into the pores and crevices of roofing materials. Cleaning a roof with bleach is akin to mowing a field of dandelions to get rid of the weeds; it seems to work at first, but the problem reappears. A wide range of fungi can settle on a roof, causing damage to the structure as well as being unsightly. The rest of the matter is made up of moss, lichen, black algae (black mould), and green mold/algae, all of which must be removed. Roof cleaning is essential for a variety of reasons, including preventing damage and premature replacement, lowering energy costs, and restoring property value.

Asphalt shingle, cedar shake, and tile roofs are the most commonly affected roofs, each of which is affected differently.
Since fungi may grow underneath the shingles, raising them until they crack and fall off, asphalt roofs deteriorate faster than other types of roofs. The fungus tendrils or “roots” often dig through the reflective granules, causing them to dislodge and fall off, causing shingle thinning, which decreases the shingle’s expected existence by years as they curl and cup.
When fungus grows on a cedar roof, it traps moisture and causes rotting, which attracts wood-feeding insects and easily degrades the wood’s integrity.
While fungus cannot destroy tile as it can asphalt or wood, it can be weakened by the weight of roof cleaners walking on the roof; tile is fragile, especially after baking in the sun for years; the damage isn’t noticeable at first, but the cracks can become dislodged and fall off as rain water washes out the cracks. In addition to the destructive damage that the fungus can cause, the home owner should expect an increase in energy costs. Fungus is usually dark in colour, and dark colours absorb light, causing air conditioners to work overtime to cool attics, crawl spaces, and second or third floors, resulting in higher-than-normal energy bills.
