Roof Cleaning
Moss removal and roof cleaning to restore your home's curb appeal.

About This Service
Bring your roof back to life with our moss removal and deep cleaning service. We use safe, effective methods to remove unsightly moss, lichen, and algae, extending the life of your tiles and improving your property's appearance.
A roof covered in thick moss isn't just visually unappealing—it's a ticking time bomb waiting to damage your home. Moss and algae act like sponges, trapping moisture against roof tiles and pointing. When winter arrives and temperatures drop, that trapped water freezes and expands, cracking tiles and destroying mortar joints. We've documented cases where a homeowner ignored moss-covered roofs for just three years, only to face a complete re-roof costing £8,000+. At A-Class Roofing, we reverse this damage with safe, professional cleaning that preserves your tiles while eliminating the problem at its source. We use careful manual scraping and eco-friendly biocide treatments—never destructive high-pressure jet washing that damages the protective membrane. The result? A gleaming roof that looks like new, tiles that last decades longer, and complete peace of mind knowing you've prevented expensive future damage.
Signs You May Need This Service

Frequently Asked Questions
Common questions about our professional roofing and guttering services.
Does roof cleaning damage the tiles?
No. We strictly avoid high-pressure jet washing, relying instead on gentle manual scraping paired with professional biocide treatments to preserve the structural membrane.
How long does the biocide treatment take to work?
The biocide acts over time, safely breaking down organic spores. You will notice your roof continuing to look cleaner with every rain shower over a 6-month period.
Why is roof moss a problem?
Moss acts like a sponge, retaining severe moisture. In freezing weather, this water expands and can crack your roof tiles or damage cement pointing.
