What Are The Dangers of Mold on My Asphalt Shingle Roof?
Your outside, admiring the beauty of your home, only to look up and notice mold and algae growing on your asphalt shingles. You know there are effective ways to clean it off, but can it wait? Are there any dangers that are involved with leaving mold on your roof? We will go over a few main things that come with leaving it on. But first of all, what is the culprit?
The mold and algae can form where moisture tends to dwell on roof surfaces. Coastal or humid climates create the most conducive conditions for algae growth. The discoloration process typically begins as small spots then quickly transforms into streaks on the roof plane. By the time the algae is visible, it likely has been present for several months or longer. Algae spores are carried by the wind or by animals and can quickly spread from one rooftop to another. This is why it must be treated immediately. Algae leads to roof stains, roof mold, lichens, fungi, moss, and mildew. If left alone untreated it soaks up moisture and cause root rot. Not only can it be damaging to your home and the structure, but it can be dangerous to your family and even pets.
Here is what leaving mold and algae on your roof can cause to happen:
Unattractive Streaks- First and foremost, mold stains and algae streaks are a major eye sore. It can detract from the beauty of your home and take away its curb appeal. These unsightly streaks are not only unattractive for your home and its value, but it can slowly weaken your roof as well. In the past, shingles were constructed using felt and asphalt. Now that shingle composition has changed to mostly fiberglass and limestone, which the GM blue-green algae thrives off of, using the limestone as their source of food. So, if you have any streaking starting, its best to get it taken care of as soon as possible before it spreads.
Shortens Roof Life– Bacteria growth on your roof can deteriorate shingles and shorten the life span of the pebbly surface. When mold is left on your roof, it will eat away at your roof creating a weak structure and costly repairs. Mold has a bad habit of eating through your shingles and working its way to your wooden beams. Eventually this causes wood rot, thus creating the perfect ground for more mold to grow. This leads to structural issues in your home and makes it susceptible to water damage, flooding events, and pests infestations.
Creates a Slippery Surface– Mold is slippery when wet. When we need to go on the roof to do inspections for leaks, maintenance, and cleaning, if we come across mold on the shingles, it can be a slippery hazard and cause us to slip and fall. Don’t allow mold to be the reason you get hurt.
