If you have an asphalt rooftop, and you live in an area where humid conditions are present much of the year, it is possible black algae will grow upon your shingles if you do not take steps thwart this natural occurrence from taking place. There are a few steps you can take to minimize the chance of black marks from appearing altogether. Here are some tips you can use to keep your asphalt shingles in the best of condition:
Keep Foliage Trimmed To Eliminate Debris Build-Up
If your home is located in a spot where trees are abundant, it will be necessary to keep tabs on the lengths of the branches at all times. If branches start to grow toward or over your rooftop, debris will be likely to land on your shingles. This debris will accumulate moisture around and underneath it if it is not removed from your shingles promptly. Consider hiring a tree service to trim back branches each year to aid in keeping algae at bay.
Clean Your Asphalt Shingles Regularly
It is important to remove debris to aid in the removal of spores which will cause black algae markings to show up on your shingles. Purchase a roof broom to push off all debris from your shingles on a routine basis. Using a garden hose or pressure washer to remove caked-on debris is also useful in stopping algae from beginning. Purchase an asphalt cleaning agent made with bleach as part of the chemical composition. This will help in killing mold spores so they do not expand on your shingles if atmospheric conditions are ripe for growth.
Add Gutters To Upper Levels To Reduce Markings
If you are constantly battling black markings with an appropriate cleaning agent, and you have more than one tier of roofing in your home, the lower levels will benefit from the addition of gutters on the tiers above. This will divert moisture and any debris washed away from the shingles to a downspout rather than having it land directly on the shingles below.
Make it a priority to clean out all gutters on your home frequently, especially after a storm passes. Failing to remove leaves, dirt, or sticks will cause water to push toward the shingles above the gutter system. This, in turn, will make these shingles more susceptible to a black algae problem.
