signs of roof problems: ALGae growth |
|
Dirt and leaves aren't the only things that collect on your roof. A neglected roofing system could also develop something far more unsightly: algae. It is possible for roofs to develop different types of algae, lichens, and fungi when bacteria take over. Many homeowners confuse algae with "roof mold" when, in reality, it is a blue-green algae that leaves dark streaks on your roof when it dies.
Algae can grow on the surface of your new roof and cause stains and growths. Until you invest in professional care, the situation will continue to worsen. Roof algae can pose a number of dangers to your home. Our residential roofing specialists want you to recognize when you should get your roof deeply cleaned, repaired, or replaced by professionals. Our free roof inspections guarantee you’ll catch new algae growth on your roof before it gets out of hand.

How to identify roof algae
How do you tell if your roof has algae growth? This depends on the type of problem you are experiencing. Roof algae tends to discolor roofing materials. It is likely that you will notice black or brown stains, or moss-covered surfaces on your roof. Algae on a roof can also appear like mold spots, leading to the common misconception. The following are signs that algae, rather than mold, are more likely causing the problem on top of your roof:
- A mossy covering
- Round lichen spots
- Spots appearing white or green in color
- Dark streaks
causes of roof algae
Unlike other plants, algae do not have leaves or roots, and are nonflowering aquatic plants. Certain environments support roof algae growth particularly well. It thrives in humid climates where there is a balance of heat and moisture. Large trees provide shade and damp conditions, which are ideal for algae growth. Algae also needs nutrients to survive on your home. The algae spores gain nutrients from the limestone filler in most roofing shingles. Your roof contains inorganic materials that will promote the growth, spread, and darkening of algae.
One spore can spread roof algae or fungus to your home. When wind blows spores onto your roof, the spores take off if conditions are conducive. Rainy weather can accelerate The more humid the air is, the less chance of algae growing, but it does not need rain if there is enough humidity in the air. A roof algae outbreak can also be caused by branches overhanging, clogged gutters, standing water, porous roofing materials, and poor roofing ventilation. You can stay ahead of algae growth by taking steps to keep your roof clear of common problems.

what are the effects of roof algae?
- Aesthetics. Roof algae can cause a number of problems for homeowners, beginning with appearance issues. It's not until algae causes ugly black streaks, dark spots, or mossy fuzz on the roof that homeowners realize they have an algae problem. Roof algae can actually detract from the curb appeal of your home.
- Property value. It may be difficult to sell your house if you have roof algae. Algae on your roof is an indication that your roof may need replacement because it is damaged. You should schedule repairs immediately if you wish to keep the resale value of your home high.
- Corrosion. Algae and lichen adhere to your roof, causing permanent damage, and eventually corroding the underlying materials.
- Deterioration of wood. Your roof may suffer from serious damage if moisture seeps into the wood. In addition to softening and rotting wood, standing water can permanently compromise its strength and safety. Roof leaks caused by wood rot can be costly to repair or replace.
- A moldy environment. The growth of mold can also occur when moisture is trapped in your roofing system. When standing water and humidity combine with growing algae spores, some molds can flourish. Mold poses severe health risks to both individuals and families.
- Structural damage. A mold and algae growth on your roof may damage its integrity beyond simple repairs if you allow it to remain there. A roof covered with algae for years may end up irreparable, and a new roof may not last as long. A roof that is rotting may need to be replaced.
- Affected other structures. A wind can easily carry algae spores to your property and attach to other buildings. Your home may begin to grow algae, but it won't be long before sheds, barns, and carports will display similar growth. The issue could spread to neighbors' homes, causing a neighborhood-wide issue.
- Detriment to health. Algae on roofs can also do serious harm to health. If mold or mildew form as a result of algae, your family may breathe in dangerous bacteria while in the house or yard. Getting rid of roof algae as soon as possible is crucial for your health and safety.
