What kind of roofs are in London Colney?
The old village around the bridge and the High Street has a few older brick buildings under clay tiles. Most homes are 1950s–1980s estates with concrete interlocking tiles, many with flat-roofed garages and porches. Napsbury Park converted large Victorian hospital buildings into homes, with big slate roofs, decorative ridges and complex valleys, alongside new-build houses.

Are there conservation areas in London Colney?

What we see in London Colney
What typically goes wrong with London Colney roofs?
Concrete tiles and mortar ridges
Estate roofs from the 1960s–80s are at the age where mortar ridges and verges crack and loose tiles appear after wind.
Flat-roofed garages
Original felt garage roofs blister and leak. Many are past repair and suit EPDM or torch-on replacement.
Complex valleys on converted buildings
The big Victorian roofs at Napsbury have long valleys and lead details that need regular attention.

Roof repairs in London Colney
In London Colney we mostly repair concrete tile roofs: ridges and verges re-bedded or converted to dry systems, slipped tiles and storm damage, plus a lot of flat-roof garage and porch work. On the Napsbury conversions, slate and lead repairs on large roofs.
Roof cleaning and moss removal in London Colney
Concrete interlocking tiles on the estates are prime moss growers, especially near the river and open land. Soft wash plus biocide keeps them clean; pressure washing removes the tile’s surface and the moss comes back faster.
Gutter cleaning in London Colney
Estate gutters are mostly uPVC and straightforward to vacuum clear. Flat-roof garages often have a single outlet that blocks and ponds water, which shortens the roof’s life.

Local questions
London Colney roofing questions
Is a dry ridge a good idea on my London Colney estate house?
Often, yes. On concrete-tiled estate roofs a dry ridge and verge system to BS 8612 stops the cycle of re-pointing.
Can you replace my garage roof?
Yes. Most old felt garage roofs are best replaced with EPDM rubber or torch-on felt, with new trims and a proper outlet.
Do you work on the Napsbury Park conversions?
Yes. We can work with your management company where the roof is shared.
