Does moss damage my roof

Updated: Jul 17

Moss can reduce your roof's life expectancy by up to 50%. Moss can clog your roof's drainage channels and fill your gutters. It is always a good idea to catch a moss buildup as soon as possible to prevent it from spreading. We have chemicals that we can spray on roofs to stop the buildup and prevent it from returning. Before any cleaning products are sprayed on the roof, it must be thoroughly cleaned with water, and then an agent to remove and kill the moss can be sprayed on. After that, we can apply a sealer to prevent future moss buildup.

It is necessary to use specialised equipment in order to thoroughly clean a roof.

If you don't have the right safety gear, including ladders, safety harnesses, and anchors, don't attempt to work on your own roof.

Consult with an expert if you have any questions about how to properly clean a roof or what kind of roofing materials you'll need to repair damaged tiles or slates.

Another thing you should do is call in a specialist for help with is cleaning the top of your house if you have no idea how to do it.

Moss blocks the water channels on tiled roofs

There is a risk that water may back up and penetrate the felt on tiled roofs because of moss. This can eventually lead to the wood battens deteriorating and maybe leaking into your house.

Damage to your tiles from moss and mould may and will result in fractures and breaks, as well as the rot of the breathable membranes and battens in your loft.

How should my roof be cleaned

Roof tiles and slates should not be cleaned using pressure washers, since they might at best damage their surface and at worst shatter them.

A low-pressure hose has shown to be the most effective since it does the least amount of harm.

It is possible to purchase an extension hose that can be linked to the hose and a long hard brush that can reach the moss that is difficult to remove.

Scaffolding should be utilised at all times while cleaning a roof, since it serves as a safety measure.

What should i do if i break any tiles / slates

If you break any slates or tiles in the process of removing moss, you should replace them as soon as you can.

When there is a hole in the roof, you should not splash water on it.

In the event that this is done, water might seep into your house and damage your ceilings.

This is something to keep in mind when you start cleaning your roof, and you should have some slate or tiles on hand in case you accidentally damage any of it.

Do I need to do anything to stop moss from growing on my roof?

When the moss on your roof has been cleared away, it's time to consider how to prevent it from re-emerging in the future.

There are a few things you can do to reduce the likelihood of moss development. Sun light is a great helper to proventing moss growing on the roof, as the sun will dry out the moss. It also stops moss from growing, so if you have any over hanging trees on your roof it would be a good idea to remove them.

A well-shaded roof prevents the evaporation of moisture, making it an ideal place for moss to grow

What other damage can moss do

Additionally, moss may obstruct the gutters and drains on your property.

Your guttering may droop over time not just because of the weight of the moss but also because of the weight of the guttering itself.

Because of this, it is a good idea to do routine maintenance on the roof in order to prevent future damage and expensive repairs to the roof.
