Terracotta Roof Tiles Alan's Roof Restoration Roof Restoration, Roof Repairs & Roof

Terracotta roof tiles are normally cleaned to have the moss & lichen removed. Terracotta tiles are made from natural clay which is a naturally a moist material. Moss & Lichen is attracted to the roof tiles surface & if left will grow & most likely restrict the flow of rain water over the tiles surface into the roofs gutters. An application of an environmentally friendly anti-fungal solution should be applied to all moss & lichen prior to undertaking the roof cleaning process. I use a product called Roof Ripper to kill the Moss & Lichen prior to the roof being cleaned.

Once the anti-fungal treatment is applied, the roof tile surface is high pressure cleaning using around 3000psi of straight water pressure. A turbo type nozzle should be used when using such high powered water pressure.

Removing the Moss & Lichen will bring the tiles natural colour to light & help ensure the roof performs as it was designed.

Old Terracotta roof tiles will become brittle over time & if so should not be cleaned as the tiles may break underfoot & water may enter the roof cavity as a result. It is also difficult to walk on & work on brittle roof tiles which makes it difficult to achieve any effective result.

Some Terracotta roof tiles may show evidence of “Tile Fretting” & depending on the extent of this problem, will not benefit from any application & should not be cleaned.

Terracotta roof tiles which have Glazing evident should not be sealed painted or coated as an application such this would have trouble with any mechanical adhesion.

Any one promoting the re-glazing or sealing or painting of terracotta roofing tiles should be avoided.

Brittle or Fretted Terracotta roof tiles should be replaced as $$$$ spent on roofs with these problems would mean $$$$ wasted.
