Avoid re-coating or total roof replacement.
Moss, lichen and fungal growth secrete acids and
enzymes which break down protective coatings.
They are both damaging and unsightly. Untreated they can ruin your roof and cost you heavily.
Roof Wash is a cost-effective solution.
How We Work
Up Front Quotation
You are provided with a written quotation and warranty statement before any work is done.
Bio-Shield is applied in a gentle, low-pressure spray. It kills moss, mould and lichen growth very quickly. The dead growth is washed away by natural weathering starting at around 2 months and continuing over about 12 months.
The final appearance will of course depend on the age and condition of the tiles or coating.
While it is not toxic to pets or plants, we take care to avoid foliage and ponds.
Armourseal Silicone Waterproofing
If necessary we can apply a protective silicone seal, using Armourseal silicone our proven
specialist roof surface sealant.
This is particularly useful for roofs made from porous materials such as concrete, clay and fibrolite.
Safety and Care
Bio-Shield is safe to use containing a combination of biodegradable surfactants for removal of moss, mould and lichen. It is safe for use on roofs that collect tank water.
Other Surfaces
Bio-Shield is also effective on driveways, fences,
paths and patios. We are happy to quote.
Future Maintenance
Stay ahead of problems and reduce costs. Contact
us every 2 to 3 years to re-treat.
You Can Buy Bio-Shield
Bio-Shield is proven effective and safe over many
years of use by Roof Wash Limited. It is available for purchase in convenient 5 litre packs which when diluted make up 100 litres. Typically this will treat an area of around 200 m2. Use it to clean up paths, patios, and other surfaces around your property.

Excerpt from Letter to the Roofing Association dated 26th June 2006
Dear Sir/Madam
You referred Andy from Roof Wash to me in May 2006. The other two companies supplied promised to quote for the work, but failed to call back and arrange for an inspection.
Andy, however did come out and quote for remedial work to our roof, which he subsequently carried out to our full satisfaction - this note is to provide you with positive feed back to that effect.
Andy is thorough, efficient, and clearly very experienced with our type of roof - the latter provided a great degree of comfort as we were concerned about the duration / extent of the damage.
I thoroughly recommend Roof Wash to other clients. Many thanks for your assistance.
Yours sincerely
V. Woolley
