Moss growth on roofs can be a common problem, particularly in areas with a cool and damp climate. Over time, moss can damage the integrity of the roof and lead to costly repairs if left untreated. Removing moss from the roof is essential for its maintenance and longevity. However, choosing the best time of year to remove moss from the roof can significantly impact the effectiveness of your efforts.
Why Is Moss a Problem for Your Roof
Moss is an invasive plant that thrives in moist, shady environments. It can cause several problems when it grows on your roof. Moss can cause water damage to your roof by trapping moisture on its surface. This can cause your roof to weaken and lose its structural integrity. The moss also creates a slippery surface, making it dangerous to walk. The moss on your roof can make it unsafe to climb up there for repairs or maintenance. Lastly, moss is unsightly and can detract from your home’s curb appeal.
When Is the Best Time of Year to Remove Moss From Roofs?
Summer is the best time to remove the moss on your roof. The weather is dryer, and the moss is inactive. The moss is more brittle during the summer, which makes it easier to remove with a broom or by using a mild pressure wash.
One school of thought says you should wait for the “growing season,” when rains begin to fall in the autumn and continue into the spring. This is because the moss will absorb as much water as possible during this period. If you apply moss treatments to your roof during this time, they will be absorbed along with the water.
The best time to remove the moss on your roof will depend on how severe the growth is and what type of roofing you have. Consult a roofing contractor such as Old Time Roofing if you are still determining the best time to remove your roof’s moss.
Remove Moss From Your Roof Using These Options
You have several options to remove moss on your roof.
Manual Removal
If it is not too steep, you can use a broom to remove moss from your roof. Sweep the moss from the roof, starting at the top. It would be best to be not aggressive as this could damage the shingles and remove protective granules.
Pressure Washing
A pressure washer is another option to remove moss. Be careful not to use too much pressure as it can damage your roof.
Chemical Treatments
You can apply chemical treatments to your roof to eliminate moss. Some products are available in containers connected to a garden hose. They can then be sprayed at ground level with enough water pressure. Some products will need to be mixed up and applied on the roof.
Use caution, regardless of which method you choose when removing the moss on your roof. Consult a roofing contractor such as Old Time Roofing if you need help eliminating moss safely.
