Why choose single-ply roofing in Magherafelt?

Single-ply is a common choice for medium and large flat roofs in Magherafelt because it covers big areas quickly, is light on the structure and has a long typical life. Wide rolls mean fewer seams, and those seams are welded and probed rather than glued.

Around Magherafelt, flat roofs are common on lock-up garage blocks on estates and on newer estates where the first extension roofs are now being replaced. 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.

What insulation and approvals does a single-ply re-roof need?

On a heated building, a full single-ply re-roof usually triggers the thermal-element rules, so insulation should be brought towards the renovation standard where feasible. In England that is 0.18 W/m²K for non-domestic and 0.16 W/m²K for domestic roofs, with Wales and Northern Ireland setting their own figures; Scottish roofs follow Section 6 of the building standards, and the council confirms whether a building warrant is required.

Single-ply suits a warm roof well, and tapered insulation can correct poor falls at the same time. A thicker build-up raises the roof, so we check upstand heights, door thresholds and rooflight kerbs at survey. Near boundaries, the external fire classification of the tested build-up can matter. We handle building control or building standards where needed; see the building regulations page.

What's included?

  • Welded details at upstands, outlets, rooflight kerbs and edge trims
  • Hot-air welded seams, each probed along its full length
  • Edge protection on every job and walkway protection around plant
  • Strip-out or preparation of the existing roof, with waste removed

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.

Is single-ply roofing noisy in the rain?

No more than other flat roofs. Noise depends far more on the deck and insulation than on the membrane, and an insulated warm roof dampens rain noise well.

Can single-ply be used on a house?

Yes. It can be used on garages, extensions and dormers, usually adhered rather than mechanically fixed. On small domestic roofs, though, EPDM or GRP is often more economical.
