Roof Cleaning Hampshire

What Roof Cleaning Actually Involves

A dirty roof isn't just cosmetic. Moss, algae and lichen trap moisture against your tiles, accelerate degradation, block gutters, and — in extreme cases — cause leaks and tile slippage. A properly cleaned roof can add 10–15 years to the life of your tiles and recover £4,000–£8,000 of home value.

Hampshire Roof Care uses a soft wash system — low-pressure application of biocide cleaners that kill the spores at the root, then a soft rinse to remove the dead growth. We do not use high-pressure jet washers, because they strip the protective glaze off concrete tiles and crack ridge mortar.

Our Roof Cleaning Process

• Manual moss scrape — heavy moss is removed by hand using soft plastic scrapers, not metal.
• Biocide application — a long-dwell algaecide is sprayed across the entire roof surface.
• Gentle soft wash rinse — pressure no higher than a garden hose, applied evenly across all tiles.
• Gutter clear — debris washed into the gutters is cleared the same day at no extra cost.
• Final treatment — a 5-year biocide is applied to prevent regrowth.

Tile Types We Clean

Our soft wash method works safely on every common Hampshire roof material:

• Concrete interlocking tiles (Marley Modern, Redland 49, Sandtoft Calderdale)
• Clay plain tiles & clay pantiles
• Welsh and Spanish natural slate
• Synthetic slate (Eternit, Tegral)
• Cedar shake and shingles

How Much Does Roof Cleaning Cost in Hampshire?

Typical pricing for a Hampshire roof clean:

• Small terraced house (60–80 m²): £350–£550
• Standard semi-detached (80–110 m²): £450–£750
• Detached house (110–160 m²): £600–£1,200
• Larger detached / chalet bungalow (160 m²+): £900–£1,800

Pricing depends on the roof size, the level of moss build-up, tile type, and access. Every quote is fixed in writing before we start — no surprises.

How Often Should You Have Your Roof Cleaned?

With our 5-year biocide treatment, most Hampshire roofs need cleaning once every 5–7 years. Roofs heavily shaded by trees or facing north may need attention every 3–4 years. If you can see green or black streaks visible from the road, it's time.

Common Questions

How much does soft-wash roof cleaning cost in Hampshire?

Typical Hampshire soft-wash roof cleaning costs £400–£950 for a standard domestic property, fully treated. A 3-bed semi is £450–£680; a 4-bed detached £700–£950; larger executive detached homes reach £1,200+. Your matched partner sends a fixed-price written quote within 24 hours of receiving photos.

Is soft washing safe on old concrete tiles?

Yes. Soft washing operates under 100 psi — about the pressure of a garden hose. It kills moss and algae chemically with biocide rather than mechanically. Even ageing 1970s concrete interlocking tiles are unaffected, unlike high-pressure jet washing which strips the protective glaze.

How long does the 5-year biocide guarantee last?

In practice, most Hampshire roofs stay visibly clean for 5–7 years after biocide treatment. Shaded or north-facing roofs are at the shorter end (5 years); south-facing or exposed roofs can go 7+ years. The written guarantee covers you against visible regrowth within 5 years.

Do you need scaffolding?

Almost never for domestic roofs. Partners use extended carbon-fibre poles that reach most roofs from ground level. Scaffolding is only suggested for chimney work or unusually tall properties (4+ storeys), and the cost is quoted separately if needed.

How long does a typical roof clean take?

Most domestic Hampshire roof cleans complete in 4–8 hours (single day). Larger detached properties or roofs with heavy moss build-up may extend to a second day. Your partner confirms the schedule the day before and typically starts between 8 and 9am.
