Mold On Roof Shingles ?
Hello,
Have noticed a fair amount of greenish Mold (or Moss ?) on shingles in some areas of my roof. Live in New England; gets quite cold up here during the winter. - Is it harmful for the Shingles ? (my primary question and concern) - Will the cold temp. kill the stuff over the winter ? - Will it rejuvenate itself in the Spring ? Or, just new patches in other areas likely ? What causes ? If it is really necessary to treat before the winter sets in, and I can get up there to spray it with something, what's good to use that won't harm the Shingles ? Would prefer, I think, a commercial product rather than mixing something up myself. Thanks, Bob |

He made a killing going around spraying bleach and water on roofs to keep down the mold. Quite an enterprising young man, actually. Low overhead. Good pay (cash). Steady customer list, plus referrals. Steve |

Put some zinc sheet neer the top of the roof - the zinc ions work pretty well at killing moss. So does copper sulphate solution. Lots of commercial preps too - but most tend to stain anything they touch. |

Thanks, Bob Once you begin to see that green stuff on your roof, that's an indicator it's time for a new roof. *Replace it before winter or you will have leaks.- Hide quoted text - - Show quoted text - Why do you say that moss is an indicator ofa failing roof? |

If it's green, then it uses photosynthesis to produce the energy it needs to survive, thrive and multiply.
Zinc, copper, arsenic and boron are all natural biocides, but some are more poisonous to some kinds of life than others. For example, the boron in borates is highly effective in killing a wide range of fungii. Borate treated liquids and borate rods are used to protect wood from fungii, like Serpula Lacrymans, otherwise known as the wood rot fungus, but is safe to mammals. Borates are even used as food additives in some countries. I'm also guessing that this moss, and it's growing on the dead leaves that are rotting to form soil on your roof. If it wuz me, I'd phone any roofing company to see if it's even advisable to remove or kill that moss. By removing the moss, you're exposing the underlying shingles to the Sun, and it's the UV light from the Sun that causes the asphalt the shingles are made of to disintegrate, thereby causing the granules set in that asphalt to come off the shingle and exposing the underlying asphalt to more UV light. As long as that moss is covering the shingles in some areas, then the shingles in those areas are protected from UV light. It may be better for you to leave that moss alone. |

The makeup of the shingles changed. I think it was copper, but could have been something else that was added to the shingles to keep the moss and mold down. In order to make them cheaper , that was left out of the shingles, or greatly reduced. I have seen it mentioned that if you take a copper wire and weave it in the shingles about every 4 or 5 rows, it will help. |

The green moss that built up on my two sheds, lifting the shingles, gets to a half inch thick. Those are both under trees with complete shading. Greg Greg? Where do you live, I've never seen moss on a roof that thick, only on the north side of trees in a deep forest. |
