The roofs we work on in Barnet
Barnet's housing is a mix, and each type has its own roofing issues:
- Victorian and Edwardian terraces around New Barnet and East Barnet often have original natural slate and hidden valley or butterfly roofs behind the parapet — a common source of long-running leaks.
- 1930s semis across the borough typically have hipped clay or concrete tile roofs. These are prime candidates for a hip-to-gable conversion when the loft is converted, and the older concrete tiles are now reaching the end of their life.
- Post-war and later housing often has shallow-pitch interlocking tile or felt flat roofs over extensions and garages that need replacing with GRP or EPDM.
- Monken Hadley and Wood Street conservation areas — work here usually needs to match existing materials, and we can source reclaimed slate and clay tile to suit.
High Barnet sits on one of the highest points in London, so roofs here take more wind and driving rain than average — slipped tiles and lifted flashing after a storm are common call-outs.
Emergency roof repairs in Barnet
If a storm has lifted tiles or you have a leak coming through a ceiling, call us. We cover Barnet and the surrounding EN and N postcodes and aim to make a property watertight the same or next day, then quote for the permanent repair.
Why choose Arkivon Group
- Fixed price agreed before work starts — no day-rate surprises
- Public and employer liability insurance
- Written workmanship guarantee on every roof
- Five-star reviews from clients across North and North West London
- Free roof inspection and quote
Frequently asked questions
How much does a new roof cost in Barnet?
A full re-roof on a typical Barnet terraced house usually runs from £6,000 to £12,000 depending on pitch, tile type and access. A 1930s semi with a hipped roof is often more because of the extra roof area. We give a fixed price after a free site visit.
Do you work in conservation areas?
Yes. In Monken Hadley, Wood Street and other protected streets we match the existing roof materials, including sourcing reclaimed natural slate and clay tile where needed.
Can you repair just part of the roof?
Often, yes. If the covering and battens are otherwise sound we will repair the damaged section rather than sell you a full re-roof. We tell you honestly which one your roof needs.
