Felt Flat Roofs In Watford
Old felt is the covering on many Watford extensions, dormers and garages, and as it ages it cracks, blisters and holds water. Replacing it with a modern torch-on felt system is a practical choice. Today's multi-layer felt is a different product from the thin sheets of the past.
Options for your roof
We install and repair across all major options to suit your home and budget.

Felt garage roof
A durable mineral-surfaced torch-on felt roof protecting a domestic garage.

Replacing felt roofs in Watford
We replace felt on garages in Meriden, Garston and Leavesden, and on back additions and dormers behind terraces in Callowland and West Watford. Typical signs are cracked laps, bubbles, moss in hollows and stains inside. We check the deck first, replacing soft boards and adding firrings for a proper fall. Then the felt goes down in layers: a base layer, a torch-on underlay and a mineral cap sheet on top to protect it from sun and weather. Edges are dressed into the gutter and flashed at the walls. It counts as a new flat roof, so our 10-year guarantee applies.
Every job starts with a free survey and a written quote. Call 01727 649498 or book online.

Torch-on felt uses a flame, so we take care around timber and on terraces where roofs sit close together. Where your roof meets a neighbour's, we seal the junction properly. If trees near Cassiobury Park or Whippendelle Woods shade your roof, keeping outlets clear helps it drain.
