A filthy roof isn’t just ugly. It’s eating away at your home’s value.
If you’ve noticed dark streaks, algae patches, or moss growth up top, you’re not alone. Llanelli’s damp Welsh weather makes it the perfect breeding ground for roof gunk.
But how much does it actually cost to sort it?
In this article, we’ll break down the real costs of softwash roof cleaning in Llanelli, explain what affects the price, and show you how to get the most value, without damaging your tiles.
You’ll also learn how to keep your roof in great condition with practical maintenance tips, discover safe and gentle cleaning methods, and see why removing algae the right way can boost your roof’s lifespan. Plus, we’ll explain why choosing eco-friendly techniques matters, both for your home and the environment.
Let’s get into it.
Why Softwash Roof Cleaning Is Different
Traditional pressure washing might blast away moss, but it can also blast off tiles.
Softwashing is safer. It uses specialist cleaning solutions to kill biological growth and loosen dirt without damaging the structure underneath. Then, low-pressure water gently rinses it all away.
Unlike pressure washing, which can cause costly damage, softwashing treats the root cause of roof stains, not just the visible surface. It’s designed to kill moss, algae, lichen, and mildew at the source, helping to prevent them from returning too soon.
If your roof is covered in:
- Black streaks
- Lichen or algae
- Moss or heavy grime
Softwashing is the method Llanelli homeowners trust.
What’s the Average Price in Llanelli?
Let’s talk numbers.
At Swansea Clean & Seal, our pricing for softwash roof cleaning starts from:
- £349 for one side of a roof
- £649 for a full clean (front and back)
These are starting prices; your actual quote may vary depending on size, slope, and how much grime we’re dealing with.
But here’s the good news: these prices include the full softwash treatment, not just a rinse.
Other companies may charge less but cut corners. We don’t. Our pricing reflects the quality of service, the safety of our team, and the long-term results our customers expect.
What Affects the Cost?
A few key factors can bump the price up or down:
Size of Roof
A small bungalow costs less than a large detached home. More tiles means more cleaning solution, more labour time, and often more safety gear.
Roof Shape and Pitch
Steeper roofs are more dangerous to work on. Extra precautions and specialist access equipment may be needed for complex angles or multiple elevations.
Access and Safety
If ladders or scaffolding can’t safely reach certain areas, we may need to bring in a cherry picker. That adds to the job cost, but ensures a proper and safe clean.
Current Condition
The level of build-up matters. Light dirt is quicker to clean, but heavy moss or lichen might need multiple treatments. Heavily stained areas may require more chemical solution and soaking time.
Gutter Condition
While not always included, we recommend pairing roof cleaning with gutter clearing. Clogged gutters often mean water is backing up onto the roof, which can accelerate moss and algae growth.

Roof Maintenance Tips After Softwashing
A clean roof is only the beginning. To keep it looking fresh and prevent early damage:
Keep Gutters Clear
Blocked gutters overflow and feed moisture back into your roof. Clear them at least twice a year to prevent rot and moss growth.
Trim Overhanging Trees
More shade means more dampness. Trimming nearby trees allows more sunlight to hit your roof, naturally keeping it drier and discouraging moss.
Check Tiles After Storms
Storms can knock tiles loose or cause cracks. Even a freshly cleaned roof can suffer damage if not checked seasonally. Stay on top of minor issues before they become major repairs.
Gentle Roof Cleaning Methods That Work
Some homeowners try to DIY it with pressure washers. That’s a mistake.
Here’s why gentle methods always win:
- They don’t lift or break tiles
- They treat the cause (algae and moss spores)
- They protect your roof’s protective coating
Softwashing isn’t just about appearances. It’s about prevention, protection, and doing things the right way from the start.
Roof Algae Removal That Lasts
Algae isn’t just ugly. It holds moisture, which weakens your roof and encourages more growth.
Our softwash solution tackles this head-on. It seeps into the roots of the growth and kills spores, not just the surface gunk.
That means longer-lasting results and less need for repeat visits. With the right conditions, your roof can stay clean for two to three years after treatment, sometimes even longer.
Extend Your Roof’s Lifespan
A dirty roof traps moisture. Over time, that leads to:
- Tile damage
- Leaks
- Costly repairs
But regular gentle cleaning (once every 2-3 years) can extend your roof’s life by 10-15 years. That’s a big saving in the long run.
Think of it as a small investment now to avoid a huge expense later.
If you’re thinking about selling your property in the future, a clean roof also boosts kerb appeal and can add to your home’s resale value.
