When is the best time for moss removal?
Updated: Feb 7
In general, the best time to remove moss from a roof is during the late spring to late fall when the weather is mild. This is because moss is more brittle and easier to remove when it's dry, rather than during the wet and humid months. That being said, we at Crux Roof & Gutter Cleaning perform roof cleanings rain or shine, in the both the dry and rainy seasons!

Perhaps what is most important is to remove moss from your roof promptly, as it can cause damage to the roofing material and cause moisture to accumulate, leading to leaks and water damage. If you're unsure about when to remove moss from your roof, or if you're not comfortable doing it yourself, give us a call! We have the necessary equipment and expertise to remove the moss safely and effectively, while minimizing the risk of damage to your roof.
How do you remove moss?
Roof brushing: Using wire brushes moss is removed from your roof. This method is simple and effective. Once moss is removed, regular maintenance with moss treatment will help ensure you never have to have moss removed again.
Crux Roof & Gutter Cleaning never uses pressure washers to remove moss from roofs.
Moss treatment and prevention options
There are several effective treatments for removing moss from roofs, and the best one for your situation will depend on several factors, including the type of roofing material you have, time of year, and the severity of the moss growth. Here are a few common moss treatments:
Commercial chemical treatments: Chemical treatments, such as moss-killing products, can be applied to the roof to kill the moss and prevent its regrowth. These treatments are typically safe for most roofing materials, but it's important to follow the manufacturer's instructions carefully and to wear protective clothing and eye protection.
Copper strips or nails: Installing copper strips or nails along the roof ridge can help prevent moss growth by killing the moss as it comes into contact with the copper. This method can work but has drawbacks including reduced effectiveness over time, adding nails to your roof, and they can be unsightly.
Sodium bicarbonate solution: Mix 1 cup of baking soda with 1 gallon of water and apply it to the mossy areas of your roof using a spray bottle. Leave the solution on for several hours, then rinse it off with a hose. This solution can help kill the moss and prevent its regrowth.
Vinegar solution: Mix equal parts water and white vinegar in a spray bottle and apply it to the mossy areas of your roof. Leave the solution on for several hours, then rinse it off with a hose. This solution can help kill the moss, but may not be as effective as other treatments.
Oxygen bleach solution: Mix 1 cup of oxygen bleach with 1 gallon of water and apply it to the mossy areas of your roof using a spray bottle. Leave the solution on for several hours, then rinse it off with a hose. This solution is safe for most roofing materials and can help kill the moss and prevent its regrowth.
We are here to help you determine the most appropriate moss treatment for your roof as well as to help you develop a maintenance plan to ensure you don't have to deal with moss ever again!
