Best time of year to remove moss from the roof

When moss accumulates on your roof, it may be a big pain. It can not only degrade the appearance of your roof, but it can also cause damage and raise the chance of leaks.

Moss normally forms earliest in the wettest environments, such as gutters! These areas and the roof must be cleaned so that no moss Rhizoids (spores) can survive. If even one spore is left behind, the entire procedure can be restarted!

Rhizoids multi-cell anchoring structures that gather nutrients and water through the moss’s exterior liverwort leaves and can quickly spread and reproduce if they break away.

It’s not as simple as it sounds to remove moss from the roof! Furthermore, because most rooftops are high and erect, it can be difficult and dangerous, especially in cold and wet weather.

What is the best time of year to remove moss from the roof?

If you reside in a cold climate, it’s advisable to wait until the weather warms up a little before attempting to get rid of the moss.

What Happens If You Leave Moss To Grow On Your Roof?

Lichen or moss will grow on most roofs, regardless of the kind of material, and a tiny patch of growth is usually not a problem. However, once it grows into a larger piece on your roof, it can become a major problem.

Moss thrives in shady, damp environments, and your roof could be just the place for it to flourish. It functions like a sponge, absorbing a lot of water and leaving your roof wet all the time. If the moisture gets underneath the tiles, it can cause the components of your roof to degrade.
