Roofing in Cockfosters: Thirties Suburbia and Ninety Year Old Tiles

Cockfosters is one of the purest examples of thirties suburban development in our coverage area. When the Piccadilly line arrived in 1933 the fields around the new station filled rapidly with the semis and detached homes that still define Cockfosters, Oakwood and the streets towards Hadley Wood today. That consistency is good news for homeowners in one sense: the roofing problems are well understood. The less good news is that almost every original roof in the area is now over ninety years old.

What Ninety Years Does to a Thirties Roof

The typical Cockfosters roof is a hipped design under clay or early concrete tiles, often with a bay window at the front and frequently with later extensions behind. Several things on these roofs are now at or past the end of their design life at once.

The tiles themselves, particularly machine made clay of the period, delaminate. Frost gets into the surface and sheds it in layers, leaving tiles soft and porous. The bituminous underfelt beneath has usually gone brittle and torn around the eaves, which removes the roof's second line of defence against wind driven rain. The mortar bedding ridge and hip tiles has cracked through decades of thermal movement. And the valleys, often original metal, have worn thin where water has run for ninety winters.

None of this means every roof needs replacing. Many can be kept sound for years with honest, targeted repair: a rebuilt valley, refixed hips, replaced tiles on the worst slope. But when several systems fail together, repair money starts chasing a roof that is finished, and we will tell you plainly when that point has been reached rather than selling you patch after patch.

Bays, Flat Roofs and Extensions

The signature thirties bay window carries its own small roof, and bay tops are a constant source of leaks in the area, whether tiled or felted. Behind the houses, decades of kitchen extensions and garages mean a large population of felt flat roofs, many overdue replacement. We renew failed flat roofs in GRP fibreglass or EPDM rubber, both seamless and far longer lived than felt.

Trees, Moss and Gutters

The mature, leafy streets that make the area desirable also feed its gutters. Blocked gutters and moss laden north slopes are the two most common maintenance issues we see locally, and both are cheap to deal with and expensive to ignore. An annual gutter clear and a moss treatment where needed will extend the life of an ageing roof meaningfully.
