How to remove moss on roof tiles
Moss are small non-woody plants that absorb water and nutrients through their leaves. They usually form dense green clumps or mats and can be found on roof tiles. Due to their water retention abilities, they act like a sponge absorbing large amounts of moisture which means your roof will be constantly wet.
The moisture can travel under your roof tiles and cause roof materials to rot. An example is the wooden components of your roof. This can compromise your entire roof architecture leading to costly roof repairs or replacements. Moss can also cause damage to your roof directly or indirectly.
The rate at which moss grows depends on several factors like the amount of rainfall in your area, the amount of sunlight your roof gets in a day, the type of trees around your property, the number of trees and whether you have had moss professionally removed in the past or not. Studies have shown that if you have a north-facing roof, there is a chance you will have moss growth as they usually receive less sunlight.
What to do if moss is growing on your roof?
Moss is bad for your roof. Whether you have roof tiles or shingles, moss can push under and create damage to your roof by creating holes and thin spots which lead to leaks. They thrive in cool damp shaded areas so if you have trees or other structures around your property that allows moisture to linger you will likely experience moss growth.
This means you should trim the trees around your property as often as possible to prevent moisture collection on your roof. Also, make sure that there are no tree branches close to your roof. Finally, you must quickly remove the moss from your roof.
What is the best way to remove moss from a tiled roof?
You can remove moss from your roof yourself or hire a professional roof contractor for the job. Moss removal by a professional roofer is usually the preferred choice as they have the equipment and expertise to do the job with lasting results.
Removing moss by yourself means you have to figure out how to kill the moss and remove it effectively. You also have to treat the roof otherwise within a short period the moss will grow back. You will need roof cleaning materials, a stiff brush or roof moss scraper and some water to clean the roof. You can find these tools and products in your local DIY store. Depending on the size of the property, you may need a ladder and a long pole attached to the brush to get the job done.
Remember to use safe or environmentally friendly roofing products so that you don’t do lasting damage to your lawn or garden. The best time for moss removal is a cloudy day as the roof cleaning materials tend to evaporate on a sunny day.
The other option is to enlist the services of your local roofer. They have the equipment, know the right cleaning products and expertise. They also follow up on the moss removal process by treating your roof.
Without using any chemicals, moss may start growing back within 6 – 12 months. It could take a few years to become prolific. Any experienced roofer will advise on the appropriate treatment and how you can keep your roof moss free.
When should I remove moss from my roof?

The best time to remove moss is when it is actively growing. Moss tends to grow quickly in the autumn, winter, spring seasons and thrives with rainfall and less sunlight. They don’t do well in summer due to sunlight.

How to stop moss growing on roof tiles
Copper and zinc strips are good for treating moss. They are affordable and environmentally friendly. They are available in major roofing stores. You can add an inch or two thick strips of copper across the ridge of your roof to protect the roof shingles and tiles from growing moss.
For bigger roofs, you may need to add more strips for an effective result. You have to add another strip at the midway point. During rainfall, the copper salt is washed down the roof from the strips fitted and cover the roof. This protects the roof shingles and tiles from moss growth. It is a perfect solution to moss growth.
Another great option is to allow sunlight on your roof. If your house has trees around it or branches of trees close to the roof, then it is advisable to have these trees trimmed regularly. Moss does not thrive in heat or sunlight.
Make sure that the roof gutters are clear at all times so that water can run off the roof. Mud, leaves and twigs should be removed. Anything that leads to moisture retention or the collection of water on your roof is fuel for moss growth. Regular roof inspections and cleaning are other great ways of preventing moss growth.
