Something is growing on your roof. It looks rustically quaint, but it also looks like you have a mini forest carpeting the top of your home. From moss to algae, growth on a roof is a common issue that many homeowners have to deal with.
Even though the streaks, stains, and fuzzy textures on your roof look unsightly, they usually aren’t a cause for alarm, and you won’t need to replace your roof, as this type of problem typically doesn’t require major repairs. Instead, your roof needs your attention and understanding, as well as a professional’s cleaning expertise.
What do you need to know about roof growths? Take a look at the dos, don’ts, and how-tos of treating this exterior issue.
Algae and Moss Basics
What’s growing on your roof? While it’s true that mold can look black, green, slimy or streaky, chances are that’s not the cause of your roofing problems.
Mold is a potentially dangerous substance that can cause respiratory issues, allergies, or skin irritations. But it isn’t likely to be the roof staining culprit that you’re looking for. Algae is a much more common roof growth than mold. Like mold, algae (when growing on a roof) can look dark, blackish, and streaky.
If the growth looks green, textured, or carpet-like, again – it’s not mold. In this case, what you’re looking at is moss.
Algae and Moss Dos
Do clean your roof if algae or moss have started growing. This doesn’t mean you should get on top of your roof and start scrubbing, as doing so would be very dangerous. Hire a roofing contractor to handle the problem for you. The professionals have the knowledge and equipment to clear the growth away and prevent it from returning.
Concerns about the roof growth returning are common and easy to understand. Your roofing contractor may be able to prevent (or at least slow down) a comeback. Copper and zinc can stop algae growth from starting. Discuss the possibility of installing zinc or copper strips on the peak of your roof as flashing or in other areas. When it rains, the metal particles will wash over the roof, protecting it from algae growth.
Along with installing zinc and copper strips, remove low-hanging branches and other plant life that shades or rests on your roof. Branches that shade your roof from the sun can create areas that hold on to moisture. Added moisture promotes algae and moss growth.
Algae and Moss Don’ts
Again, don’t attempt to clean the roof growth off yourself. Algae and moss are slippery and make it easy for the DIY person to slide and fall. Don’t get up onto your roof and clean it off; always call a professional for this job.
Keep in mind, just because you shouldn’t climb your roof to clean the growth doesn’t mean that you should attempt to wash it off from the ground. Your garden hose isn’t powerful enough to remove the growth.
While it’s tempting to rent a pressure washer and give the roof a deep spray, the strength of this type of clean can ruin your asphalt shingles. Don’t use a pressure washer, from the ground or anywhere else, to remove algae or moss.
Algae and Moss How-Tos
If you can’t clean the algae or moss off from the ground and you shouldn’t use a high-powered pressure washer, what can you do?
The answer to this question is easy – you can pick up the phone and call your roofing contractor.
