Roof materials are designed to last for a long while, with many new roof installations coming with warranties that can last for decades. With that said, even the hardiest roof shingles will need some regular maintenance and care to stay in good shape. If you have noticed that some combination of moss or algae has begun to grow on your roof, it is imperative that you take action to fix the situation before it causes damage to your home. Here are some tips on how to eradicate the problem on your roof and more importantly, keep it from coming back.
Bleach is a Cost Effective Roof Cleaner
There are many professional products on the market that claim to remove moss or algae from your roof, but a more cost effective solution might be a bleach and water combo. Gently spray a 50 percent bleach and 50 percent water solution on the moss or algae directly. This should do a good job of getting into the root, if one has developed, and killing it at the source. Be sure to wash all of the bleach away when you are done cleaning, though, so there are no negative effects on your roof materials.
Install Zinc or Copper Strips
Algae does not mix well with zinc and copper, according to RCI, a professional trade organization for building and roofing consultants. Zinc and copper strips can help kill off algae before it gets a foothold on your roof. You can purchase these strips at any home improvement store. The idea is that when it rains, a few molecules of these minerals will wash down over your roof and kill any moss that had begun to form on your shingles.
Hire a Professional
While bleach and copper strips can usually do the job, one way to really step up the protection of your roof would be to hire a professional roofing contractor. Roofers have access to many tools and shingle-safe chemicals that can wipe out any algae or moss growth completely. Find a roofer you like, have him or her come out once a year to clean your roof, and provide a layer of protection against moss growth for the next year.
Letting moss and algae get out of control on your roof is a good way to ruin your shingles or even void your warranty. If you see one of these substances on your roof, you can try treating it with a bleach and water solution or install copper or zinc strips to prevent future growth.
