Why Roof Cleaning Isn’t Just About Looks

If you’ve noticed moss, algae, or black streaks on your roof, you might be wondering:
“Do I really need to clean my roof?”

The short answer? Yes — and sooner is better than later.

Here in Somerset, our damp climate creates perfect conditions for moss and lichen to thrive. And while a mossy roof might seem harmless at first, it can quietly cause serious and expensive damage if left untreated.


đź’§ The Hidden Costs of Leaving Your Roof Dirty

Let’s break down what’s really happening up there — and what it could cost you:

  • Moss holds moisture like a sponge, keeping your roof constantly wet. This weakens tiles, causes frost damage, and shortens your roof’s lifespan.

  • As moss dries, it breaks off and falls into your gutters, leading to blockages, overflowing water, and internal damp patches.

  • Algae and lichen stain your roof, making your home look neglected — even if the rest of the property is spotless.

  • Blocked roof valleys and downpipes increase the risk of leaks and costly internal water damage.

A neglected roof isn’t just unsightly — it’s a silent liability.


âś… How Roof Cleaning Works (And What You Should Expect)

There are a few different roof cleaning methods — each with pros and cons. Here’s what we use:

  • Low-pressure washing — removes moss, algae, and dirt instantly without damaging tiles

  • Softwash chemical treatment — helps remove stains and kill organic growth

  • Biocide application — a professional-grade treatment that continues to work for up to 12 months and helps prevent moss from returning for up to 5 years

At Somerset Roof & Gutter Cleaning, we tailor the method to your roof type, condition, and tile strength — ensuring a safe, long-lasting clean every time.


🌿 When Should You Clean Your Roof?

The best time to clean your roof in the UK is spring or autumn, when moss growth is active but weather conditions are manageable. However, we clean year-round — and there’s no bad time to remove roof moss if it’s already causing issues.

Signs it’s time for a clean:

  • Green clumps of moss on the roof or ground

  • Black streaks or white crusty lichen patches

  • Overflowing or blocked gutters

  • Your neighbours’ roofs are spotless and yours is visibly worse

  • You’re preparing to sell or rent your home


đź’¬ “Can I Just Leave It and Deal With It Later?”

You can — but it usually means higher costs down the line. Roof tiles aren’t designed to hold moisture for long periods. Even if you don’t see visible damage now, the long-term impact of moss, damp, and gutter overflow can be serious — including rot, leaks, and damaged insulation.

Cleaning your roof is preventative maintenance — like servicing your boiler or clearing your gutters.
