How much does it cost to have moss removed from your roof?
Roof moss largely grows in damp, shaded areas and can spread across your roof quickly as they release spores. Small patches of moss on your roof is practically harmless. However, large patches of moss growth on your roof can cause damage directly and indirectly to your roof. Moss is known to retain moisture against the surface of your roof which causes the roof framework or other roofing materials to rot.
What are the main causes of moss growth on a roof?
Moss thrives on damp cool surfaces. The absence of sunlight or less sunlight is a perfect environment for moss to grow. On your roof, it grows in the cracks between each shingle. With time it starts to lift and loosen shingles thereby leading to leaks. The damage by roof moss can lead to holes, thin spots and leaks. This could mean costly repairs or an expensive replacement.
When you think of roof repairs or replacement you have an image of a large outlay. That's why we advise that roof moss should be removed quickly. Your roof should be inspected and maintained regularly so that issues like moss growth are spotted and dealt with as soon as possible.
Is it worth removing moss from your roof?
Yes, it is worth it. As highlighted earlier, small patches of moss growth are harmless. However, a bigger patch of moss on your roof will affect the structural integrity of your entire roof. Large patches of moss on your roof can also prevent your roof water drainage system from functioning properly. This means rainwater would not run-off into the gutters and there would be pools of water on your roof that could damage your roof.
Moss alone may not damage the roof tiles. However, the main benefit of moss removal is to keep the gutters clear and functioning properly for water drainage and to prevent the roof from freezing to pieces. While it is important to remove moss from your roof, we do not recommend that you use anything that disturbs the surface of the tiles which would make them porous and susceptible to leaks.
Roof tiles and slates can become porous due to the overgrowth with moss when rainwater infiltrates into the material. The moisture can lead to roof tiles bursting at lower temperatures. Hair cracks from moss and filth also increase the possibility of a leak in the roof.
Always use an experienced and specialised roofer for roof moss removal. They are equipped with the right tools and information to do the job. Your roof is an extremely important part of your home. While it defends and protects your property from the weather elements, the tiles, shingles and roof framework must be protected to extend the lifespan of the roof. You don’t want anyone working on your roof as it could cost you in the long run.
