Why demoss your roof?

A roof covered with moss looks messy, and that in itself is a reason to intervene quickly. But the moss also affects your roof covering and border crossings. The small carrots attach themselves to every roof covering and weaken the material. Do you allow the moss to proliferate too long? Then cracks and cracks occur. And that lead to moisture problems: prevention is the message!

Why demossing roofs is really useful

Cleaning your roof by having it demineralised has a number of interesting advantages:

  • Prevent damages and cracks: The moss cover makes the roof covering more porous. When it freezes, the moisture in the moss will expand, causing cracks and cracks in the roof covering. Because the moss hides those small cracks, they have plenty of time to get bigger, which can lead to water infiltration. That penetrated moisture can in turn cause the roof covering to crack further.
  • Preventing leaks: The formation of cracks and cracks due to moss and dirt increases the risk of leaks in the roof.
  • Extended lifespan: A roof is subject to wear due to heavy rain, temperature fluctuations. Moss provides an acceleration of that wear process.
  • Beautiful appearance: Together with the facade, the roof is the first thing you notice when you view a house. By having the roof demineralized, it will continue to look well cared for. This way you leave a positive impression on yourself, visitors and potential buyers if you ever want to sell your house.
  • Optimal energy consumption: A roof with moss is no longer in optimum condition. There is a risk that the roof insulation will be affected, resulting in energy loss.

Removing moss on roof: Procedure

Making a roof moss-free usually takes the following steps:

1. Preparation

It is important that the craftsmen have easy access to the roof so that they can do their job properly. Put flower pots, patio furniture, the parasol, etc. aside in advance. If you do that work yourself, the craftsmen do not have to clear the way themselves. That means fewer working hours, which means you can save on labor costs.

Objects that are fixed and cannot be set aside are best covered with old blankets, a plastic sheet, etc. This will prevent dirt or anti-moss product from ending up on it.

2. Shut off the water drain

The drainage of rainwater is best sealed when removing a roof. This way you prevent water with pieces of moss and anti-moss product from ending up in the rain pit. The product limits the use of rainwater while the pieces of moss can lead to blockage.

3. Remove moss from the roof

After these preparatory works, it is the turn of actual moss control. Via anti-moss products, with the help of the high-pressure cleaner, by spraying, by brushing everything away, etc. Depending on the roof covering, the professional uses specific products and materials.

Certain anti-moss products must be able to act for a while. The exposure time depends on several factors such as the type of roofing material, the weather conditions, the degree of pollution, etc.

Keep it safe

We cannot repeat it enough: your safety always comes first. Therefore, never go up your roof unprepared. A sturdy, stable ladder is an absolute must when you unhook your roof yourself. An aerial platform is of course even better. Put on solid shoes, because a mossy roof is often slippery.
