Why is my Somerset home covered in moss? (And how we fix it)
If you live in Somerset, Devon, or Bristol, you’ve likely noticed that our roofs look a bit "greener" than those in other parts of the country. At MM Roof Cleaning Services, the #1 question we get is: "Is this just an eyesore, or is it actually damaging my house?
The "Perfect Storm" for Moss in the South West
The UK’s South West is the ideal breeding ground for moss and lichen. Our unique climate provides the three things moss loves most:
- High Humidity: Our proximity to the coast keeps roof tiles damp for longer.
- Porous Tiles: Many homes in Wellington, Taunton, and Bridgwater use concrete or clay tiles which act like a sponge, giving moss roots a place to grip.
- Surrounding Nature: Our beautiful, tree-lined streets mean millions of spores are constantly being blown onto your roof.
Is Moss Damaging My Roof?
In short: Yes. While a little bit of green might look "country-chic," heavy moss growth leads to serious maintenance issues:
- The "Freeze-Thaw" Effect: Moss acts like a wet sponge. In winter, that water freezes and expands, which can cause your tiles to crack or "spall."
- Weight Stress: A roof covered in saturated moss can add hundreds of kilos of extra weight to your timber rafters.
- Gutter Failure: As moss falls, it blocks your gutters, leading to damp walls and foundation issues.
Our Professional Solutions
At MM Roof Cleaning Services, we don’t believe in a "one-size-fits-all" approach. We use a combination of professional techniques to get your roof back to its best safely
For older or more delicate tiles, we perform a Manual Scrape. We use specialized tools profiled to fit your specific tile shape, safely removing the bulk of the moss by hand. Once clear, we apply an HSE-approved Biocide. This soak-in treatment travels deep into the pores of the tile to kill the remaining microscopic spores, providing long-term protection and preventing regrowth.
2. Professional Low-Pressure Washing
For a deep, immediate transformation, we offer Low-Pressure Washing. Many people worry about "jet washing" a roof, but our professional equipment is specifically calibrated for this task:
- Precision Control: Unlike a standard high-pressure blaster, our system uses a controlled, lower pressure that is safe for the integrity of your tiles.
- Deep Clean: It effectively removes years of dirt, atmospheric soot, and stubborn lichen that a scrape alone might miss.
- Granule Protection: This method ensures your tiles' protective surface remains intact while delivering a uniform, clean finish.
Why We Stand Out: The 12-Month Guarantee
Because we combine physical removal with professional treatments that target the root of the problem, we are confident in our results. Every full clean is backed by our 12-month Moss Free Guarantee and qualifies you for our Roof Care Plan to keep it looking great forever.
