Moss Removal Hampshire

Why Hampshire Has a Moss Problem

Hampshire’s mild, damp climate — particularly across Southampton, the New Forest fringe, and the Meon Valley — is a near-ideal environment for moss growth. Most concrete tiles are visibly affected within 10–15 years, and north-facing or tree-shaded roofs can show heavy moss in under 5.

Beyond the look of it, moss creates real problems:

• Water retention — moss holds 10× its weight in water, keeping tiles wet between rainfalls.
• Tile damage — freeze-thaw cycles in wet moss split concrete tiles over time.
• Gutter blockage — dislodged moss clogs gutters and downpipes, causing overflow and damp.
• Insurance issues — insurers occasionally flag visibly mossy roofs during damp inspections.

Our Moss Removal Process

1. Manual scrape — heavy moss is removed by hand using plastic scrapers, never wire brushes or metal.
2. Soft brush down — loose debris cleared, gutters checked.
3. Biocide soak — a slow-release algaecide is applied to kill spores at the root.
4. Soft wash rinse — gentle low-pressure rinse to lift any remaining residue.
5. 5-year treatment — final biocide coat to prevent regrowth.

How Much Does Moss Removal Cost?

• Light moss, small roof: from £320
• Moderate moss, semi-detached: £480–£720
• Heavy moss, detached: £700–£1,400

Pricing depends on roof size, access, moss density and tile type. We quote a fixed price in writing — no extras added on the day.

When to Call

If you can see green or black streaks from the road, your roof is overdue. Heavy moss visible from ground level usually means 5+ years of build-up. Letting it run further accelerates tile damage and pushes the eventual repair cost up.
