Roof Cleaning and Moss Treatment Thetfordpg

Roof Cleaning

Softwash Biogrowth Treatment

That grimy, weathered look on your roof isn't just cosmetic.

 

Moss, algae, and lichen work their way into the tile surface over time, retaining moisture, accelerating wear, and in winter, causing freeze damage that cracks tiles from within.

 

We use a gentle soft wash technique with an HSE-approved biocide to clear the growth properly, treating the cause rather than masking it — and protecting your roof for the long term.

 Moss, Lichen & Algae Removal

Left untreated, organic growth on roof tiles does more than affect the look.

 

Moss retains moisture and adds weight; lichen burrows into the tile surface; algae breaks down the tile material itself. Regular treatment is the most cost-effective way to protect your roof.

​

We remove the growth and apply a professional biocide treatment to prevent it returning.

Our Method:

Step 1: Moss & Growth Removal

​

We remove all moss, algae, and biogrowth from your roof — by gentle scraping or low-pressure steam cleaning depending on your property's needs. No high-pressure blasting, no roof climbing.

Step 2: Gutter Clearance & Preparation

​

With the roof clear, we clean out the gutters and carefully detach the down pipes, fitting temporary sleeves to catch any treatment runoff during the next stage.

Step 3: Biocide Treatment

​

We apply an HSE-approved biocide treatment across the entire roof surface. This targets remaining spores and prevents moss, algae, and lichen from returning — keeping your roof clean and protected long after we've finished.
