Felt Flat Roofs In St Albans
Felt is still the covering you will find on many flat-roofed garages and extensions in St Albans' outer areas. When it fails, modern torch-on felt is a practical way to replace it. Built up in layers with a mineral finish, it is much tougher than the felt it replaces.

Felt flat roofs around St Albans
In Jersey Farm, Marshalswick and Batchwood, we regularly replace felt on garages and extensions built alongside 1930s to 1970s homes. Signs of trouble include cracking along the laps, blisters, moss in hollows and water staining inside. We start by checking the deck and replacing soft boards, adding firrings so water drains properly. A base layer and torch-on underlay are bonded down, and a mineral cap sheet is torched on top to shield the felt from sunlight and wear. Edges are dressed neatly into the gutter. Every new flat roof we lay is covered by our 10-year guarantee.
Every job starts with a free survey and a written quote. Call 01727 649498 or book online.

Torch-on felt involves a naked flame, so we take care around timber and older buildings, particularly in the city's conservation areas. On terraces and semis, we seal your roof against your neighbour's with proper flashings. If your roof is shaded by trees, keeping outlets clear helps it drain.
