How to remove mould from roof tiles.

More than likely it is spreading from your attic into your roof. While it will not produce the same results as pressure cleaning it offers a quick and convenient option for cleaning the mould off your roof. As you did in the previous step walk backwards when you are spraying away from the wet tiles and onto the dry ones. You must let the roof dry before a second application of mix.

Start on lowest row of shingles and work your way backwards to the upper part of the roof. This will prevent the solution from draining in your direction. Lichen on terracotta roof tiles is particularly unappealing to the eye and is best handled before it has a chance to cake in and ruin the tiles. When mould is growing on top of your roof it is often indicative of problems that started within the home.

Inspect the roof for any remaining fungus. Spray the entire roof thoroughly. This will remove all the moss and lichen as well as any built up dirt. The product needs to be diluted 1 part with 5 parts water in a garden sprayer.

If it is slimy or any sort of residue comes off on your hand repeat the above steps. Next rinse the shingles thoroughly with a garden hose at low pressure. Roof mould is. Allow the solution to soak into the shingles for at least 15 minutes.

Allow the roof to dry thoroughly. Start from the top shingle and rinse downward to prevent water seepage. If they are severely molded you may want to give it a little longer.
