When it comes to roof maintenance, two problems often get in the way. These are moss and algae. Both might appear to be simple dark or green stains. However, they pose different dangers and need their own approaches to treatment. The same goes for prevention. We know the difference, and can therefore ensure we provide the best roof cleaning in Dorking and other parts of Surrey.

Knowing the distinctions between algae and moss is necessary for homeowners looking to protect their investment. You can also increase kerb appeal and prevent costly repairs in the long term. We’re going to discuss the two growths and their differences in detail below, so read on to expand your knowledge.

Moss

Mosses are small, soft flowerless plants that grow in shaded, moist settings. They are particularly prominent in places that don’t get much sunlight. Moss is a non-vascular plant, as it doesn’t have traditional roots like other plants. Rather, it uses rhizoids to attach itself to exteriors and absorb moisture. It thrives in places where water is retained for long stretches.

One thing to keep in mind is moss spreads in clumps. It can also form dense mats or clusters. They can cover shingles, tiles, or other roof materials. In the worst cases, they can appear as a green, thick, carpet-like layer on roofs. If left untreated, this seemingly harmless growth can prove very damaging.

As for how moss damages your roof, there are a few ways this happens. It is important to ensure you are aware of them so you know the importance of getting professional roof cleaning in Dorking and other areas.

One is moisture retention. Moss can hold onto water similar to a sponge. When it resides on your rooftop, it keeps the area wet. That can result in mildew, rot, and even structural harm with time.

Moss can also lift roof materials. When it grows, it works its way under the tiles or shingles, lifting them gradually. This produces entry points for water.

Roof material deterioration is another complication. Materials are meant to repel water and last a long time. Moss undercuts this by holding moisture against the surface. It accelerates the breakdown of substances like wood shakes, tiles, and shingles.

Algae

In contrast, algae are microscopic organisms that show up as dark streaks or stains. They’re particularly common in humid settings and on asphalt shingles. Though commonly referred to as algae, Gloeocapsa magma is a kind of cyanobacteria. It feeds on the limestone filler in some shingles. You may want to arrange roof cleaning in Dorking to tackle it.

There’s a flat growth pattern here. Algae spread out in thin layers over the rooftop. Normally, this creates dark green or long black streaks. Algae don’t have roots either; they live on top and feed on organic mediums.

Algae don’t grow in the same way moss does, but their existence still poses a danger. With aesthetics, the dark stains present are ugly and make a roof seem old.

Surface deterioration is another problem. As time progresses, algae feeds on your roof materials. This causes gradual deterioration and wear.

Then there’s heat retention. Algae-affected roofs absorb more heat from the sun. The result can be greater cooling costs during warmer months. Your home’s energy efficiency will decrease.

Why the differences matter?

Moss and algae may seem similar to many people. However, they differ in regards to growth patterns, biology, and the effects on your property. Understanding the distinctions will enable you to take the ideal course of action against them. Solutions for both are different, so using the wrong methods can worsen the issue.
