Most homeowners are loath to see unwanted growths anywhere on or in their homes. So seeing something unwanted on your roof can be cause for concern. But should you be concerned? Is growth on the roof indicative of bigger problems? And what can you do about it? Here are some answers to your questions.
Is It Mold, Mildew, Algae, or Moss?
What many homeowners may automatically assume is mold could, in fact, be one of several types of organic growth. Mold, mildew, algae, and moss are easily mistaken for one another. But they are different types of growth, some of which are more dangerous than others. Fixing the problem starts with identifying which type of growth it is.
Does the Growth Indicate Roof Problems?
The bottom line is that mold, mildew, algae, and moss are all indicative of moisture problems. However, some of these organic masses—namely moss and algae—generally come from the environment.
If you live in a moist, humid, or rainy climate, your roof may attract moss and algae from the air and soil. These growths do not necessarily mean your roof has any structural issues. Have mold or mildew? Then it's more likely that moisture within the roof is the source.
Is the Growth Dangerous?
Should you worry about any of these growths? The answer is yes, but for different reasons. All of them can damage the shingles, caulking, sheathing, and framing of the roof if left untreated. And if the problem began with moisture getting inside, that moisture causes its own problems.
However, if your growth is mold or mildew, it can mean added hazards for humans and pets. These can cause health problems, especially respiratory problems, inside the house.
How Can You Get Rid of Mold, Mildew, Algae, or Moss?
Removing growths from the roof depends on how they arrived. If there are leaks that allow rain or snow to get into the structure, you must fix the source of the problem in order to get rid of the growth. However, if the moss or algae is environmental, you might be limited to seasonal cleaning or treatment to keep it in check and make sure it doesn't eat into the roof materials.
Where Should You Start?
As mentioned, the first step toward deciding how to handle growths on your roof is to learn more about what makes them up. A professional roofing contractor can do this for you.
