Why You Need a Professional Roof Cleaning
No matter where you live, your roof has the potential to accumulate moss, algae, and lichen. These growths are caused by several factors including moisture, filler in asphalt shingles, soil, tree sap, leaf fibers, and airborne spores. They should be cleaned off as the growths can lower the curb appeal of your home and lessen the life span of the roof. It’s important to have a professional roof cleaning which will ensure a longer life span for the roof and raise the value of the home.
It may seem like certain types of shingles would attract these growths while others may not but this isn’t the case. Moss, algae, and lichen growth is a problem that affects every type of roof. You may also be asking what steps you can take to prevent them from growing but unfortunately there’s no way to prevent this. However, a professional roof cleaning can restore the roof to its original look.
What Is Growing on Your Roof?
There are several things that can grow on your roof causing you to need a professional roof cleaning. You can usually tell visually what it growing on the roof based on its color and substance. Algae will appear as black or green streaks. Moss and fungus will appear as green, spongy clumps on the roof. Lichen will appear as gray, orange, white, or yellow spots that are usually no larger than a quarter.
Getting Rid of Moss, Algae, or Lichen
If you have moss, algae, or lichen growing on your roof, it’s highly recommended that it’s professionally treated with an anti-algae solution. This is a specially formulated solution that is specifically designed to remove algae, moss, and lichen from the roof. It will also remove the black streaks or stains that have accumulated on the roof. However, this should not be a DIY project. Professional roof cleaners should be brought in to avoid damaging the shingles.
Due to the fact that algae are microscopic airborne organisms that aren’t visible to the naked eye, the entire roof should be cleaned rather than just visible stains. The visible stains aren’t the only areas with algae, they’re just the areas that are most densely populated by it. A cleaning of the whole roof will ensure that all algae is properly removed.
Methods of Removal
While it may seem like you could just pressure wash your roof to remove the moss, algae, or lichen, that could have a negative effect on the roof. The Asphalt Roof Manufacturers Association recommends specific solutions that should be used for the roof cleaning. Further, major shingle manufacturers advise against using a pressure washer as even on low this can dislodge and remove granules from the shingles. The dislodging of granules can cause a reduced life span of the shingles and can potentially void their warranty. Other cleaning materials that can cause damage to shingles include scrubbers, agitators, shampooers, and hand brooms.
The DIY Option
While it may seem like you could clean moss, algae, or lichen off the roof yourself, you should leave this work to professional roof cleaners. The process of cleaning the roof involves mixing chemicals, using equipment, and safety issues like climbing a ladder. If something goes wrong, the medical bills or injuries aren’t worth the amount that you would save by cleaning the roof yourself.
What Happens If It’s Not Cleaned?
If a roof with moss, algae, or lichen is not professionally cleaned, the black streaks and stains could cause the shingles to lose their ability to reflect the sun’s energy and provide insulation. This will result is higher electrical bills. Another problem if these growths are ignored is that the roof may deteriorate quicker forcing the owner into a new roof sooner than expected. The best way to avoid needing a roof replacement is to have your roof cleaned every few years. In a warmer climate like Florida, you should have your roof cleaned even more frequently. Another tip is to keep tree branches trimmed at least six feet from the roof. Having branches hanging over the roof and providing constant shade is not ideal as it can help the growth of moss, algae, and lichen.
If you have moss, algae, or lichen growing on your roof, it’s important that you have a professional roof cleaning. Attempting to clean it yourself or letting it go can result in a premature roof replacement. If you need your roof cleaned, call on Roof Cleaning Pros & Pressure Washing to do a quality job.
