How Much Of A Problem Is Moss On Roof Tiles

Slate like other roofing material is not immune to the growth of moss and you will often hear conflicting advice on whether to take measures to discourage growth or actively encourage its growth. So which is the right answer?

Firstly, let’s look at the disadvantages of moss growing on roof tiles.

The biggest problem is not so much the moss on the tile but the fact that it can often fall off and obstruct drainage. If those drainage points are blocked for any length of time then it can result in having to undertake costly repairs if damp finds its way into the house or diverts water in areas vulnerable to leaking water.

If moss is causing a problem, then the more of it you have, the more costly it will be to hire a professional contractor to remove it. If you want to stop moss growing on your roof then installing copper ridges will discourage moss growth.

There is however a school of thought that maintains the view that moss is actually good for a roof and help protect it from frosts.

Taking a common sense view, regular roof inspections should be carried out in any case to ensure that problems don’t get out of hand. As long as you keep an eye out for any potential issues such as leaks from guttering, then moss shouldn’t be too much of a problem.
