Felt Flat Roofs In Borehamwood
Felt is the original flat roof covering on most Borehamwood homes, from the garages and porches of the 1950s and 1960s estates to later extensions. Today's torch-on felt is very different from that old single-layer material, combining several bonded layers with a mineral cap sheet on top.

Replacing worn felt across Borehamwood
When we survey old felt in Borehamwood, the same issues come up: cracks along the upstands, blisters where moisture is trapped, bald patches where the chippings have washed off, and repeated patching with bitumen paint. The decking is often rotten at the edges. We strip the felt, replace damaged boards, and torch on an underlay and a mineral cap sheet, fully bonded. New drip edges at the gutter and properly dressed upstands at walls finish the roof, giving a traditional, practical result that suits post-war homes.

Torch-on felt works well where you want to match neighbouring garages in a block, or where a traditional finish suits the house. Since heat is used, we take care around timber fascias, which are often old on these homes. If you would like to compare, we can quote for EPDM or GRP too. New flat roofs carry our 10-year guarantee.
