Roof Cleaning

Why clean your roof?

Over time, algae, moss, and other organic matter can accumulate on your roof. This buildup can lead to structural damage and deterioration if left unchecked. Regular cleaning helps remove these contaminants and prevents potential damage.

Extend the lifespan of your roof

By removing debris and preventing the growth of mold and mildew, you can help increase the longevity of your roof. A clean roof is more likely to withstand harsh weather conditions and maintain its integrity for a longer period of time.

Improve energy efficiency

A dirty roof with an accumulation of dark stains and algae can absorb more heat from the sun. This additional heat can make your home warmer, causing your air conditioning system to work harder to maintain a comfortable temperature. Cleaning your roof can help reflect sunlight, keeping your home cooler and reducing energy consumption.

Enhance curb appeal

A clean roof greatly enhances the overall appearance of your home. It can give your property a fresh and well-maintained look, which can increase its value and attract potential buyers if you ever decide to sell.

Prevent health hazards

The growth of mold, mildew, and algae on your roof can pose health risks to you and your family. These organisms release spores into the air which can be inhaled, potentially causing respiratory problems and allergies. Regular roof cleaning helps eliminate these health hazards and provides a safer living environment.

Biocide Treatment

We apply a biocide treatment to your roof to eliminate the growth of algae, moss, lichens, and fungi over time, increasing your roof’s lifespan.

What is biocide?

Biocide is a chemical treatment that we apply to your roof after the steam cleaning stage.

Its main role is to prevent microbial growth (moss, mould, and algae) and to extend the life of your roof. The combination of biocide and low-pressure high-heat steam means you get a thorough clean paired with long-lasting protection of up to 3 – 5 years.
