What You Need to Know About Biocide Treatments for Roof Cleaning

What is a Biocide Treatment?

Biocide treatment is a form of microbial control that uses chemicals to destroy or inhibit the growth of living organisms such as bacteria, mould, and algae. When used on roofs, it helps to remove moss, algae, dirt, and other contaminants while keeping the roof in good condition for longer. Biocide treatments added to water create a powerful cleaning agent that can protect against further growth and degradation of roofing.

You can use biocides with traditional methods to clean your roof; they can be part of a routine cleaning process and will not harm your roof's waterproof membranes. However, biocides do not last forever, so you'll need to reapply them every 2-3 years (depending on the product and the local environment).

How Do Biocide Treatments for Roof Cleaning Work?

Biocide treatment for roof cleaning is a simple and effective process. The chemicals used in the biocide treatment disrupt bacteria and mould membrane cells, killing them safely and quickly. This helps to eliminate current growth and guard against other moss, algae or bacterial infestations.
