How to clean roof tiles?

Cleaning with a pressure washer

Pressure washing roof tiles is one of the most prevalent techniques of cleaning them, yet this is a controversial method. The strength of the water stream can remove the finish of the roof tiles, so using a high-powered pressure washer could do more harm than good. The granular finish has been engineered to gradually wear off over time, thus removing it early can result in the roof tiles having a substantially shorter lifespan. When utilizing a pressure washer, there is a risk of flooding the roof/loft space since the water will penetrate any minor cracks or crevices in the roof tiles.

Making use of a trowel or a stiff brush

Scraping moss, algae, and grime off roof tiles by hand is a simple but time-consuming way of cleaning. Scrape the moss and dirt off the tiles with a tool like a trowel. The drier the day, the better, because moisture will allow moss and other debris to stick to the tiles. Alternatively, scrape the dirt off with a sharp brush - both procedures are quick and easy ways to clean your roof tiles.

Using chemical substances

A number of chemical solutions have been developed to assist in the cleaning of moss and algae-covered roof tiles. Moss killers, fungicides, and anti-moss treatments can be sprayed on roof tiles to eliminate any plant life that has grown on them. This should be done after scraping the roof tiles with a trowel or firm brush to ensure that the chemical goes into all the cracks and crevices where mold, algae, and other filth can become trapped.

Remember to cover any nearby plants and grass while using moss killing chemicals; the chemicals are designed to kill live organisms, not only moss and algae. Ensure that any chemical runoff does not pollute the environment.
