Roof Tile Cleaner is a chlorinated roof tile cleaning chemical that tackles mould and black staining on tiles and paving, from 5 L to 200 L drums.

What it does

Black mould and its staining dull a roof long before the tiles wear out. Roof Tile Cleaner is Sierra's chlorinated roof cleaning solution, with sodium hypochlorite under 10 per cent and sodium hydroxide under 5 per cent. It is a colourless, strongly alkaline liquid (pH 12.0 to 13.0) with a mild chlorine smell, and it does not burn. Sierra's catalogue draws the line clearly: Citrus 6000 handles dirt and grime, Roof Tile Cleaner handles mould.

Where to use it

Tiled roofs with mould and black staining, and paths, driveways and pavers carrying the same growth. Sierra's price list shows each pack with a vent cap. Find it in our stone and paving care range, and use Citrus 6000 for general roof grime.

How to use

1. Put on impermeable gloves, overalls and an apron, plus splash proof goggles and a face shield.
2. Protect aluminium, zinc and tin fittings, which the SDS lists as incompatible.
3. Sierra publishes no dilution rate or dwell time, so ask us for the maker's directions before you start.
4. Rinse thoroughly and control run off; the SDS says it harms aquatic life until diluted.

Safe on / avoid

Roof tiles and mould affected paving. Keep it off aluminium, zinc, tin and their alloys, and away from acids, which react with alkalis and release heat. Never mix it with other cleaners. Store it below 30°C where possible, out of the sun, with lids closed. Trial a hidden tile or paver first. Read the Safety Data Sheet before use.
