How to Save Your Roof from Moss Damage: A Complete Guide
Learn how to save your roof from moss damage with this complete guide. Find out what causes moss growth, how to remove it effectively, and how to prevent it from coming back.
What is moss and why is it harmful to roofs?
Moss is a type of plant that does not have roots, stems, or leaves. It reproduces by spores and can grow on almost any surface, including roofs. Moss thrives in moist and shady conditions, which are often found on north-facing or tree-shaded roofs.
Moss can cause several problems for roofs, such as:
Moss can cause several problems for roofs, such as:
Lifting shingles - Moss can grow underneath shingles and push them up, creating gaps and exposing the roof deck to water damage.
Trapping moisture - Moss can hold water like a sponge and keep the roof wet for longer periods of time. This can lead to wood rot, mold growth, and structural deterioration.
Attracting pests - Moss can attract insects, rodents, and birds that can damage the roof or create nests in the attic.
Moss can also pose a health risk to humans - It can increase allergies and the release of toxic compounds into the air. Some people may experience skin irritation, respiratory problems, or eye infections from contact with moss or its spores . Moss can also harbor harmful microorganisms, such as fungi, bacteria, or parasites, that can cause infections or diseases. One example is sporotrichosis, a fungal infection that can affect the skin, lungs, bones, joints, or central nervous system. It is also known as "rose gardener's disease" because it can be transmitted by handling contaminated plant matter, such as rose bushes or sphagnum moss .
Therefore, it is important to take precautions when handling moss, such as wearing gloves, goggles, and masks, and washing your hands thoroughly after contact. It is also advisable to avoid ingesting moss unless you are sure it is safe and clean. If you have any doubts, consult a doctor or a nutritionist before consuming moss.
How to remove moss from the roof using different methods and products
There are several ways to remove moss from the roof, depending on the severity of the infestation and your personal preference. Here are some common methods and products:
Physical removal
This involves using a garden hose with a spray attachment and a soft-bristled scrub brush to rinse off and scrape away the moss from the roof. This method is simple and cheap, but it can be labor-intensive and potentially damage the shingles if done too roughly or frequently.
Chemical removal
This involves applying a store-bought or homemade solution that kills the moss and prevents it from growing back. Some examples of commercial products are Wet and Forget Liquid Mold Remover ($30, Walmart) [Wet and Forget Liquid Mold Remover] or Bio-Advanced Moss and Algae Killer ($19, The Home Depot) [Bio-Advanced Moss and Algae Killer]. Some examples of homemade solutions are bleach mixed with water and heavy-duty cleaner or baking soda mixed with water and dish soap. This method is effective and easy, but it can be toxic to plants, animals, and humans if not used properly or rinsed off thoroughly.
Professional removal
This involves hiring a roofing contractor or a moss removal service to clean your roof using specialized equipment and techniques. Some examples of professional tools are a stiff long-handled brush and a trowel or a specialist scraper and modified jet washer. A high-pressure cleaner with a dirt blaster can also be used for roof moss removal. This method is fast and safe, but it can be expensive and require scheduling.
How to prevent moss from growing back on the roof
To keep your roof moss-free in the future, you should take some preventive measures , such as:
Improving ventilation - Make sure your attic has adequate ventilation to reduce moisture buildup and lower the temperature of the roof surface. You can install vents, fans, or ridge caps to improve air circulation in your attic.
Increasing sunlight - Trim any overhanging branches or trees that block sunlight from reaching your roof. Sunlight will dry out the roof and discourage moss growth.
Installing zinc or copper strips - Zinc or copper strips are metal strips that release zinc or copper ions when wet. These ions inhibit moss growth by creating an unfriendly environment for them. You can install zinc or copper strips along the peak or ridge of your roof or under the shingles near the ridge. However, metal strips may have some drawbacks, such as being a leak risk, requiring periodic replacement, and having a limited range of effectiveness.
Choosing algae-resistant shingles - Algae-resistant shingles can help you avoid algae, another organism that grows in wet and shady conditions. These shingles are treated with copper granules that prevent algae growth. However, they may not be effective against moss, which has a thicker and more resilient structure than algae.
Cleaning your roof regularly - Cleaning your roof regularly can help you remove any moss spores or debris that could lead to moss growth. You can use a garden hose, a soft-bristled brush, or a low-pressure washer to rinse off your roof. You can also use a chemical solution, such as bleach or vinegar, to kill any moss or algae on your roof. However, you should be careful not to damage your roof or harm your plants with these methods.
