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.

Moss Removal in Eastleigh and Southampton

Eastleigh and Southampton between them account for roughly half our moss-removal jobs. Both have the same problem: dense postwar housing on concrete interlocking tiles, a damp marine-influenced climate, and mature tree cover that shades the north-facing roofs.

• Eastleigh (SO50, SO53) — Boyatt Wood, Hiltingbury, Chandler’s Ford, Bishopstoke, Fair Oak and Velmore. Mostly Marley Modern and Redland 49 concrete tiles, typically 8–15 years between cleans before regrowth becomes visible from the road.
• Southampton (SO15, SO16, SO18, SO19) — Bitterne, Sholing, Shirley, Bassett, Lordswood and Portswood. Heavy coastal moisture means moss takes hold faster here than inland; we typically recommend a 5–7 year clean cycle vs the 10+ years you can get away with further inland.
• Surrounding villages — Romsey, Hedge End, West End, Bursledon, Botley, Otterbourne and Colden Common all fall comfortably in our coverage radius.

Pricing for moss removal in Eastleigh and Southampton typically lands between £380 and £850 for a standard residential roof, depending on moss density and tile size. Larger detached properties in Bassett, Lordswood, Chandler’s Ford and Hiltingbury can reach £1,200 where the moss has been left untreated for 10+ years.

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.
