Careful, no-pressure roof cleaning for Harpenden
Traditional hand roof cleaning with no high-pressure washing — carried out across Harpenden and the surrounding Hertfordshire villages including Wheathampstead, St Albans and Redbourn. We are based in Ampthill, roughly 20 road miles away, roughly 20 miles from Ampthill.
Harpenden is one of the more affluent towns in the area, with substantial Edwardian and interwar detached houses around Rothamsted and the Common on natural slate and clay tile, alongside more modest inter-war semis in Southdown, mostly on concrete tile. Property sizes and roof complexity here tend to be greater than in the smaller commuter villages closer to Ampthill.
Working in AL5
We work Harpenden alongside Wheathampstead, St Albans and Redbourn, so if a neighbour wants the same roof cleaning done we can usually fit both into one visit.
Harpenden falls under St Albans City and District Council and covers the AL5 postcode districts. We reach it via A1081, M1 J9 and M1 J10 for roof cleaning, which is why the 20-mile run from Ampthill rarely costs us a whole morning.
Access varies street to street here, and it matters more for roof cleaning than people expect: Many of the larger detached properties have generous driveways suited to full access, though some of the older streets near the High Street have tighter frontages and controlled parking that need to be worked around.

Tile types we handle here
Concrete interlocking tiles: porous with age, hold moss firmly, respond well to hand scraping followed by biocide.
Clay plain and peg tiles: brittle at the nibs and never suitable for pressure washing — hand work only.

Questions we get asked
Why does moss and algae grow so quickly here?

Is access a problem on Harpenden properties?

Can you do neighbouring properties on the same visit?
Usually, and it is worth asking. Once we are set up in a Harpenden street the additional cost of the house next door is much lower than a separate visit — the same applies across Wheathampstead, St Albans and Redbourn.
What happens to the moss you remove?
It is collected, bagged and taken away. We do not flush it into the gutters or leave it in the borders.
