Best Time of Year to Remove Moss from Roof. You are not alone if you have tried to remove moss from your roof but failed to see any results. Moss killers are difficult to apply and can be toxic, but they do the job right. Chemical-based moss killers often need a specific kind of moss and will be ineffective in some conditions.

Chemical-based moss killers will remove moss from your roof in the same way that organic methods do, so it is up to you to decide which one will work best for your situation.

Best Time of Year to Remove Moss from Roof

The Best Time of Year to Remove Moss from Roof. Summer is the best time of year to remove moss because live moss is easier to kill than dormant moss.

With weather varying state to state, there is no specific date that is right for every location. However, between May through October is generally a good time to treat your roof.

When the temperature is above 15ºC, it’s going to take longer for the chemicals in the moss killer to act. When it’s cold, you can use this moss killer.

Why does the Time of Year Affect Moss Killers?

Why does the Time of Year Affect Moss Killers?. Summer is the best time to remove moss because it’s actively growing. When the weather is hot and dry, the spore production will stop. In addition to this, spring’s wet weather has an advantage over summer.

Moss killers need water to be capable of being absorbed. This means the more water there is, the easier it will be to kill mosses. There is usually a lot of rain in spring, which makes moss more vulnerable to dying.

If it’s not the rainy season, you need to spray water on your roof.

If you missed moss clearance in summer, it’s the next best season to clear away the moss since it becomes active and when sudden weather changes occur. Moss killers work best in October when they are most active, that can disrupt the survival of moss in winter.

A good example of a moss killer is Wet & Forget Moss Multi-Surface Outdoor Cleaner Concentrate, which is safe to use on your roof and does not require any scrubbing.

Moss Removal in Spring

Spring accelerates mold growth. Mold thrives in damp, warm conditions – the perfect description of spring weather. Therefore, early spring is a great time to remove any existing moss on the roof to curb its growth. In addition, make sure to keep an eye out for any new growth and take steps to remove it as soon as possible.

It is best to wait for spring weather to do your moss removal. According to OSHA, more than 50 people die from roof falls each year in the US. The spring weather is favorable enough to work on the roof with minimal risk.

Fall Moss Removal 

Fall is an excellent time to remove moss from your roof. The sun is still visible, meaning the roof will dry up fast even if you wash it with weed killer. It’s also an ideal time because the temperature isn’t too hot or too cold. You won’t have to worry about the moss growing back as quickly because the conditions aren’t as favorable for its growth.

It’s important to remove moss from your roof in the fall, as well as in the spring. Follow-up moss removal in fall is also beneficial as it allows you to remove any moss that may have started growing on the roof during summer. If you don’t remove the moss in fall, you may have to wait until spring to do so, when the weather is nicer.

Controlling Moss Growth on Roof

Moss can be a problem for any home, but especially for those with roofs. Not only is it unsightly, but it can also lead to roof damage if left unchecked. The best time of year to remove moss from your roof is in the fall, when the weather is cooler and the moss is easier to remove. Here are some tips for getting rid of moss:

  • Start by wetting down the mossy areas with a hose. This will make it easier to work with.
  • Use a stiff brush to scrub away the moss. A putty knife can also be helpful in getting under stubborn patches.
  • Rinse the area well with water once you’ve removed all the moss.
  • Apply a fungicide to help prevent future growth. Be sure to follow the manufacturer’s instructions carefully.

By taking care of your roof and removing moss regularly, you can help extend its life and keep it looking its best.

Causing Damage to the Roof and Home

Moss can be a beautiful addition to any home, but it can also cause extensive damage to your roof and home. Moss absorbs water, which can lead to the development of mold and mildew. Additionally, moss can hold water against the surface of your roof, causing the shingles to deteriorate and potentially leading to leaks.

If you have moss on your roof, it’s important to remove it as soon as possible to prevent further damage. The best time of year to remove moss is in the fall, when the weather is dryer and the moss is easier to remove. However, you can remove moss at any time of year as long as you take care not to damage your roof in the process.
