Torch-on felt roofing in Craigavon

Torch-on felt in Craigavon is a layered roof: an underlay, sometimes an intermediate sheet, and a mineral-faced cap sheet, each heat-bonded to the one below. It is generally the most economical of the main systems and suits garages, extensions and larger roofs on blocks and shops alike.

Why choose torch-on felt roofing in Craigavon?

On larger roofs in Craigavon with poor falls, torch-on felt pairs well with tapered insulation, which builds the fall into the insulation boards. That deals with ponding properly while adding insulation, rather than patching the low spots and waiting for the next leak.

Craigavon's flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions, with plenty on newer estates where the first extension roofs are now being replaced too. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.

Should I choose torch-on felt or a different flat roof system?

Choose torch-on felt when you want a proven, layered system at a sensible price, particularly on larger roofs, blocks of flats and commercial buildings where several layers give useful redundancy. It is a weaker choice where hot works are hard to manage safely.

For: generally lower cost per square metre; two or three layers, so a single defect in one layer need not cause a leak; tough mineral finish; long track record and a British Standard code of practice; repairs can be made with compatible materials.

Against: needs a naked flame unless a cold-applied or self-adhesive alternative is used; shorter typical life than EPDM or GRP; the finish is functional rather than decorative; more laps to detail than a single sheet.

On small domestic roofs near timber, EPDM avoids the torch entirely. GRP gives a harder, neater surface. For an overlay, a liquid-applied system is often simpler. Large commercial roofs may suit single-ply, and older buildings may suit mastic asphalt. See our comparison guide.

What's included?

  • Deck inspection with replacement of damaged boards
  • Vapour control layer and warm-roof insulation where needed
  • Two- or three-layer reinforced bitumen membrane with staggered laps
  • Hot-works checks and fire watch on every torch-on job

Building control in Northern Ireland

In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.

How much does a torch-on felt roof cost in Craigavon?

£1,350–£2,300 for a typical 18 m² garage roof in torch-on felt, at Northern Ireland guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can I paint or coat an old felt roof?

Reflective or liquid coatings can extend the life of a sound felt roof, but they will not fix wet insulation, a rotten deck or poor falls. A survey shows whether coating or replacement makes more sense.

Can torch-on felt go over an existing felt roof?

Sometimes, if the old roof is dry, well bonded and the deck is sound. Often stripping is better, because overlaying can trap moisture and hide rot; our guide to overlay or strip explains how we decide.
