Roof Cleaning in Yeovil – Professional Moss Removal

💧 Why Clean Your Roof in Yeovil?

The Best Roof Cleaning Methods We Use in Yeovil

Not every roof in Yeovil is the same — and not every roof cleaning method is right for every property. That’s why we always carry out a free site visit before recommending the safest and most effective approach for your specific roof type, condition, and level of moss or staining.

1. Manual Scraping + Biocide Application

This traditional method involves removing the moss manually with scraping tools, followed by an application of biocide to kill leftover spores and help prevent regrowth.

Advantages:

• No water or pressure is used during the removal phase

• Useful for visibly thick moss that can be lifted off in sheets

Drawbacks:

• Despite being seen as “gentle,” scraping can damage fragile or weathered tiles, especially on older roofs

• It’s very labour-intensive, meaning longer times and higher costs

• Risk of tile movement or cracks with metal tools if not done carefully

We’ve seen scraping lead to broken tiles more often than low-pressure washing — so unless it’s the safest option for your roof, we usually recommend a better alternative.

2. Softwash Chemical Treatment (Sodium Hypochlorite) + Biocide

This method involves applying a roof cleaning chemical (sodium hypochlorite — a type of bleach) to kill organic growth like algae and light moss, followed by biocide.

Advantages:

• Minimal physical impact on delicate or lightly stained tiles

• Helps fade staining and treat surface-level algae or lichen

Drawbacks:

• Not powerful enough to remove thick or well-established moss

• The bleach can damage surrounding plants, paths, or painted surfaces if not carefully controlled

• Lingering chemical smell for a few hours after treatment

This is best suited as a maintenance clean, or as a follow-up treatment after a more thorough moss removal — not ideal for roofs heavily affected by moss buildup.

3. Low-Pressure Washing + Biocide (Our Preferred Method for Most Yeovil Roofs)

If your roof tiles are in good condition, this is often the best method — offering powerful results without the downsides of scraping or harsh chemicals.

Here’s why Yeovil homeowners love it:

• We use a flat-surface cleaner (not a lance), which spreads the pressure evenly and avoids damage

• The water pressure is reduced to a safe, controlled level — it’s gentler than scraping, and only water touches the tile surface

• We work from secure mobile scaffold towers to clean at the right angle, avoiding the risk of walking on the roof or spraying upwards from ladders

• Delivers instant visual transformation — perfect for boosting kerb appeal before a house sale or simply freshening up your home

• Biocide is applied after cleaning to ensure moss doesn’t return

This method delivers the cleanest result with the least risk — which is why it’s our go-to recommendation in Yeovil where roofs often suffer from year-round moss growth.

💧 Why We Always Finish With Biocide

Moss and algae might be removed on the surface, but without biocide, the roots and spores are likely to return. That’s why we apply a professional-strength, HSE-approved biocide treatment after every clean (unless otherwise requested).

What makes it so effective:

• Targets the root system of moss, algae, and lichen

• Prevents regrowth for 2–5 years, depending on your roof’s location and shade level

• Works gradually over time to keep your roof clean for longer

• Reduces how often you need a full clean, saving you money long-term

• Safe and compliant with UK industry standards

Yeovil homes — especially in shaded areas or close to trees — are particularly prone to moss and lichen. Biocide keeps these problems in check and helps maintain your clean roof’s appearance throughout the seasons.

Every roof clean includes an in-person assessment and clear explanation of the best method for your tiles — no guesswork, no upsells, and no unnecessary risks.
