The product worked well. The tiles I cleaned were covered in ground in dirt and algae which I haven't cleaned for a long time. I followed the instructions and they now look like new.

Product Description

A Fast Acting Professional Grade Roof Cleaner for Concrete, Slate & Terracotta Roof Tiles

Roof Clean Xtreme is used by many roof cleaning professionals to clean roofs without the need for pressure washing. The formulation is a fast acting, high performance roof cleaning product that makes cleaning roof tiles easier than ever before.

Once applied, Roof Clean Xtreme can quickly remove most types of organic growth from roof tiles that have become covered in algae and ingrained dirt over time. Furthermore, this roof tile cleaner will work on clay, slate, terracotta and concrete tiles without risking damage to the roof.

To achieve the best roof cleaning results, just dilute the roof cleaning product 1:1 and use a watering can or sprayer to apply. After around 60 minutes just rinse off or lightly pressure wash the roof tiles with water. In areas of heavy surface contamination or ingrained soiling, leave the product on the surface for longer and scrub in to agitate. In some cases a re-application of the product may be necessary.

Application

Prior to use, remove any loose debris or heavy layers of moss with a scraper or brush.

Dilute product at a ratio of 1:1. Apply liberally to the roof tiles using a watering can or pump sprayer. Leave on the surface for around 60 minutes before cleaning off with water. There shouldn't be any need to pressure wash the roof tiles.

The product becomes inactive once dry, so avoid application in hot weather to avoid losing product to evaporation. In general one application should be sufficient to removed most ingrained grime and organic growth.

Health & Safety

Roof Clean Xtreme contains chlorine which can bleach and stain fabrics and other sensitive materials, so take care to avoid contact with such materials during application.

  • Wear protective gloves and goggles at all times
  • Keep pets off the surface being treated when wet

Product FAQs

Q: Hello, does this product prevent / inhibit future growth of algae, lichen and moss as well as clean? Thanks

Tony

A: No, this product is a powerful roof tile cleaner. After cleaning with the Xtreme Cleaner, you should apply a 'biocide' to act as a preventative. We would recommend our 'Green Clear' or Green ClearPRO for this purpose

Response from Alex

Q: Will this stain black guttering/Fascia and if so how would you reverse this?

Dillin Blackmore

A: This will not stain upvs guttering or fascia. It can also be applied to wood or metal. Hope that helps.

Response from George

Callum
