Why Moss Grows Faster on Roofs in Harrogate — What You Should Do About It

Harrogate's Climate Creates Ideal Conditions for Moss Growth

As mentioned previously, the rainfall is high in Harrogate which leads to damp conditions overall. It is quite normal to expect rainfall consistently throughout the year which leads to moisture and hence the perfect environment for moss to settle and grow very easily. Because the damp conditions may continue for long periods of time, especially the winter months, the moisture present will encourage the moss to grow across your roof.

The fact that the temperature is in general quite cool, with limited sunlight, the evaporation of the moisture is a very slow process. If you are lucky enough to have a roof that is exposed to direct sunlight, the drying process will be quicker with less chance of moss building up. In general, north-facing roofs, or properties with trees or other buildings that block sunlight will be more susceptible to damp and moss.

Roofing Materials Common in Harrogate Encourage Moss Growth

There are various roofing materials commonly used in Harrogate that can become porous over time, such as clay tiles, concrete tiles or indeed slate. There may be small gaps on the surface of the tiles that can allow moss to settle and grow easily, especially common in older roofs that will be more vulnerable.

Moss finds it easy to grow on rough surfaces which can generally be found on older roofs. As the roof ages, tiny cracks may appear which will be the perfect environment for moss to grow, especially as these tiles can very possibly retain moisture.

Why is Moss a Problem for Your Roof?

There are three main factors that can lead to problems with your roof due to moss. The first is that moss effectively acts like a sponge and is holding water on the surface of your roof. Over time, this will definitely weaken the materials that have been used and the deterioration can be sped up because of the damp conditions in Harrogate.

As moss can easily grow in many conditions, there is a significant risk of tile damage in the long-run. It likes to grow between the tiles which may lift them up allowing water under the surface and consequently leading to structural damage or internal leaks which can be expensive!

Having good drainage is very important. If gutters are blocked by moss falling into them, your property may be damaged by blockages of rainwater building up and damage to both foundations and walls.

Is There Anything I Can Do to Prevent Moss Growth?

The good news is yes! Checking for early signs of growth of moss on your roof and taking subsequent actions to remove it will prevent serious problems in the future. It is a good idea to regularly check your roof, particularly after the winter season.

There are many specialist, professional cleaning companies that will wash your roof without being aggressive (with a pressure washer for example) to ensure the moss is removed in an effective manner without any damage to the materials.

It is always important to maintain the gutters allowing for water to be drained away from your property. This will help with the removal of moisture which will make it more difficult for moss to grow.
