Is it Mold? Is it Algae? What's the difference?

Most people assume the black streaks on their roof, siding, deck or patio is dirt or even mold… Many times, especially in areas like Anderson SC that are near the lake, it’s actually algae. That’s the good news! The bad news is that mold and mildew are still very prevalent and can wreak expensive havoc on your home. Don’t worry though, all different types of organic growth on your home are treatable! Let's discuss algae vs. mold… what’s the difference?

Mold is much more dangerous and difficult to remove – primarily because it is often caused by deeper issues in your home. Algae is simply a plant enjoying a life full of sunshine and moisture on your roof, siding, deck, or concrete. Luckily, algae is much more common than mold. What do they have in common? They are both living organisms that can be treated similarly using a safe and biodegradeable soft wash process that kills off all growth in just a day’s work.

More on algae: Algae is a naturally occurring moss-like plant that spreads by air-borne spores. In especially humid climates like Anderson SC or Greenville SC, algae is a very common problem and asphalt roof shingles and vinyl siding seem to get it the worst. Algae itself, if not treated, can eat away at or damage your roof and force lots of unnecessary expense. And, it just looks bad! Having a fresh, clean roof or Back 2 New vinyl siding immensely boosts curb appeal. This can be especially important if/when you decide to sell your home. Most buyers see quite a few different homes, and the one with the sparkling roof and siding will stand out for sure. If you are not selling your home, it can be just plain embarrassing!

More on Mold: Mold is not nearly as common as algae. BUT, the most severe toxic mold can cause health problems in the home from asthma to irritated eyes and throat to head-aches and lung issues, so it’s important to identify exactly what the streaks on your roof or the color on your home is. Mold typically forms in damp, warm and poorly ventilated attics and basements and can spread to your roof, siding and deck. In South Carolina, this does happen more than other areas further north. Hopefully, you’re just dealing with algae. It’s a good idea to inspect your crawl spaces, attics and basements a few times a year to be sure mold isn’t silently forming under your nose.

So what can be done to remove and prevent these problems? The easiest way to deal with mold and algae is to prevent it. Regular house and roof washes will keep your home sparkling and safe. That is the only “cure.” Some things are best left to professionals – but if you do decide to go the DIY route, please educate yourself on the proper techniques by going to some of the vinyl and roofing manufacturers' websites or call them and find out what their recommendations are before tackling this difficult and expensive project yourself. The most common mistake do-it-yourself pressure washers will run into is applying too much pressure.
