Roofs across the UK are made from an array of different materials. The choice can depend on a number of things including the location, the cost, and the aesthetics. You can expect to find everything from tiling (made from clay, concrete, slate, or stone), metal, shingles, thatch, and even timber in some cases. One thing that all of these substances have in common is they can experience stains, struggle with dirt, and become home to different types of organic matter.

All that growths like moss, algae, and lichen need to grow are food, water and air. The latter two are available in abundance on roofs in the UK. Food is a different matter, with some materials offering more than others. For example shingles tend to have a limestone filler to thicken them. This is a good food source for the organisms. Timber is another great one, especially when the protective coatings wear away and leave the substrate exposed.

The organic materials mentioned above all tend to grow on shaded parts of a roof that remain damp for longer. Once they are established here they can spread across the surface, putting the materials at risk as they go as well as posing problems for gutters and drains.

The best option is to have the roof cleaned and use a protective biocide to deter growths. Care needs to be taken when working on roofing, ensuring that the services leave the surface clean but don’t cause damage to the materials.
