Felt Roofs in Hull

Why torch-on felt is still the practical choice for many roofs

Modern torch-on felt is a long way from the single sheet of tarred felt many older garages still carry. It is a reinforced bitumen membrane laid in two or three layers, each one heated with a gas torch so it bonds to the layer below, and finished with a cap sheet faced in mineral granules that shield it from sunlight and wear. The result is a tough covering bonded together from deck to surface.

Felt is usually the most cost-effective of the three flat roof systems we lay, which makes it a sensible fit for garages, outbuildings, porches and rear extensions where you want a reliable roof without paying for features you will not use. It also handles roofs with plenty of upstands against walls, because each layer can be dressed up and sealed in turn. Where a roof will be walked on regularly, we may suggest GRP instead.

Not every felt problem needs a new roof. A single split, a lifted lap or a tired upstand can often be cut out and patched with new felt torched into place. When blisters, cracks and bare patches have spread across the surface, or the deck has gone soft, patching just moves the leak along, and we will tell you plainly that a full recover is the better use of your money.
