Moss build-up on your roof can breed more problems than the build-up itself. What seemed like a small problem can actually blow up and cause you your entire roof. But first, let us differentiate a moss from an algae or fungi. Moss are non-vascular plants that lives by absorbing water through their leaves and not roots. These plants are fond of places that are damp, with  a lot of moisture, and is generally dark or crowded. Their reproduction involves the spread of spores that are either spread through the air, insects, birds, and other agents. Unlike algae, mosses are classified as small plant. Algae is described as a single celled plant growing together in a cluster. Meanwhile, fungi, by relation is more identified to animals than plants.

Here’s a list of things that we’ve compiled so you’d know what troubles can arise from the moss on your roof:

1.     LEAKS

Moss build up usually stems from small chip offs of a broken roof shingle. But because it is small, often times, homeowners neglect the chip until it is too late. Moss favors these areas as a place to thrive. Broken shingles can sometime collect water, more than it should, or more than it can handle. When a spore of moss attaches itself to that environment then it starts using the accumulated water to grow its roots and eventually small leaves. Mosses do not grow huge leaves, the longest leaf of a moss can be as small as a millimeter but since it grows thick, that’s where the problems starts to bloom.


As mentioned above, mosses can grow into thick shrubs if neglected long enough. If moss grew near the gutters of your roof, chances are; it will crawl to the area where there is more water. Yes, your gutter. Mosses thrive in places where there is excessive supply of water that is why they are always mistaken for algae or fungi.

We all know that clogged gutters have multiple repercussions to the roof. Not only is it a problem when it rains because rain water cannot drain, it can also accumulate water putting pressure to the foundation of the gutters. If the collected water is heavier than what the gutter foundation can handle, then your gutters might just break and fall down.


Every now and then, we have to check on our roof to avoid the costly repairs. However, having mosses on your roof can make the surface slippery which can make it difficult for you to inspect your roof.

If you see patches of moss on your roof, it is best to not attempt to cross the area. We suggest that you call experts to do the inspection for you, so you do not compromise your safety.

Our team at Yorkshire Roofing can do the inspection and produce a thorough diagnosis of what your roof needs based on our observations. We can also provide you a reasonable quote about the areas that you would like to be repaired to avoid problems in the future.


Since mosses can look like mini jungles on your roof, some insects like spiders and specific species of cockroaches get attracted to the area where there is vegetation. Since these places have not been disturbed for long, the insects will find this place a great place to breed. Which means, you do not only have to deal with a broken roof in the future, you also need to call the pest control guys to remove the unwanted insects in your house.


What could have been a simple cleaning job is now a bigger problem because the mosses have already grown thick under your roof shingles, has already accumulated so much water, and have attracted insects. While mosses seem like a simple problem that is easy to eradicate, it can cause. A huge problem when left unattended. If the scenarios above fits your home, you now have to take care of repairing the shingles, holes on the roof, cleaning your roof, checking for insect infestation, and many more.
