Roofers in Barnet, from Victorian terraces to Mill Hill semis

Family-run roofers in Barnet, working from High Barnet and Whetstone down through Finchley, Mill Hill, Hendon and Edgware. Best Top Roofing Ltd repairs leaks and slipped slates, renews dormer and extension flat roofs, rebuilds chimneys and re-roofs houses with a 10 year guarantee. Ring 07429 820474 and Thomas will come out and give you a fixed written price.

The London Borough of Barnet holds a lot of different roofs between the Hertfordshire border and the North Circular. New Barnet and the streets around Finchley grew with the railway and the Northern line, so they are lined with Victorian and Edwardian terraces and semis under Welsh slate, with shared chimney stacks and rear outriggers. Hampstead Garden Suburb is a different world: Arts and Crafts houses with steep clay plain tile roofs, big chimneys and dormers, protected as a conservation area. Mill Hill, Edgware and the streets off the A41 in Hendon are mostly 1920s and 1930s semis with hipped plain tile roofs and tile-hung bays. Right across the borough the loft has been converted, leaving a box dormer and a flat roof sitting on an old pitched roof.

Those conversions are where many Barnet leaks start. A dormer cheek with tired lead, felt on the dormer top that has blistered and split, or a roof window that was never flashed properly will put water into a bedroom ceiling long before the main slope gives trouble. On the slate terraces, nail fatigue lets slates slide, and the valleys and back gutters between outriggers fill with leaves and overflow. On the inter-war houses the original plain tiles are near the end of their life: the nibs snap, the hip mortar washes out and the felt underneath has gone brittle. We repair each of these properly, lay EPDM or GRP on dormers and extensions, dress new lead and re-roof whole houses when patching stops making sense.

In Hampstead Garden Suburb, where the Suburb Trust also has a say on alterations, and in the borough's other conservation areas, we match the clay tile, keep the original ridges, chimneys and dormer details, and talk to you about consent before work is booked. Everywhere else the job runs the same way. Thomas comes out, gets up to the roof, checks the loft where it matters and shows you what he found. You get a fixed written price, with no extras added once the scaffold is up. The family carries out the work, the site is cleared every day and a new re-roof comes with a 10 year guarantee. Homeowners, landlords with flats in converted houses and shops on the high roads all get the same service. Ring 07429 820474, Monday to Saturday, 8am to 6pm.

Barnet questions

Can you fix a leaking loft dormer in Finchley?

Yes. We check the flat top, the lead cheeks and the flashings where the dormer meets the main roof, find which one is letting water in and repair it. If the dormer top has had its day, we re-cover it in EPDM or GRP. You get a fixed written price first.

Do you re-roof houses in Hampstead Garden Suburb?

Yes. We match the clay plain tiles and keep the ridge, hip and chimney details the Suburb is known for. We go through the consent position with you, including the Hampstead Garden Suburb Trust, before any work is booked.

My Mill Hill semi still has its original tiles. Repair or replace?

Thomas looks at the tiles, the battens and the felt underneath. If a handful of tiles and the hip mortar are the problem, we repair it. If the felt has perished and tiles are snapping across the roof, we tell you a re-roof is the better spend and show you why.
