You will see black stains, moss, lichen, or possibly some other kind of fungus on your roof. “How do I clean it now?” is the issue.
You are not alone; in fact, I’m sure you’ve seen the same issue on other roofs in your area. If you’ve done some research, you’ve probably found that the issue exists in every town and state.Do you want to learn more Cleaning Black Roof Algae Tampa Florida
What exactly is it? The black stains you see are a form of black algae, which is a living organism that feeds on the nutrients in your roof. It can only live on north-facing roofs or heavily shaded parts of your roof because ultraviolet rays from direct sunlight destroy the spore and direct sunlight dries out your roof, preventing moisture from congregating. On the north-facing and shaded parts of your roof, the exact opposite occurs. To live, moss, algae, lichen, or any fungus needs three things: air, food, and water. The food source comes from the shingle contents; if you have wood shingles, the wood is the obvious food source; if you have asphalt shingles, the limestone used as a thickening agent is the food source.
Is it causing damage to my roof? Yes, I’ve seen moss eat through two layers of shingles and into the wood underlayment; black algae, on the other hand, is a surface feeder that eats the shingle granules when spreading across the roof. Look in the gutter on the contaminated side; I guarantee you’ll find discarded shingle granules there. So, yeah, it can halve or worsen a 40-year shingles life expectancy.
I’m not sure what I should do about it. Here you have three options: clean it yourself, contract a professional roof cleaning service, or repair it. Let’s take a look at these three possibilities.
Replace it – If you have that kind of cash, that’s awesome! The bad news is that, despite the fact that new shingles on the market are algae resistant, buyers should exercise caution. Read the warranties carefully; they are only guaranteed for an average of 10 years because it takes so long for noticeable signs of algae to appear on the field. If you have the cash and want to guarantee yourself a clean roof for the next ten years, go for it.
