Single-ply membrane roofing in Northallerton

For landlords and businesses across North Yorkshire, including Northallerton, we strip and re-roof in single-ply membrane, welding and probing every seam. Upstands, outlets and rooflight kerbs are formed in the same material, and the fixing pattern is worked out for the roof's exposure to wind.

Why choose single-ply roofing in Northallerton?

Single-ply often suits blocks and mixed-use buildings in Northallerton because no flame is used on the roof, which can make work around residents and businesses easier to plan. Hot-air welding still needs care, but the fire risk is lower than with torch-on.

Northallerton's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on lock-up garage blocks on estates too. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

How much does a single-ply roof cost in Northallerton?

Is single-ply the right system for my roof?

Single-ply is usually the right system for medium and large flat roofs, such as shops, offices, units, surgeries, clubs and blocks, where speed of installation, light weight and long life matter. On a small domestic roof it can work well, though it is not always the most economical choice.

In its favour: lightweight; quick to lay over large areas; flame-free, as the seams are welded with hot air; long typical life; welded details at rooflights and plant; lighter-coloured membranes reflect more sunlight.

Against it: only one waterproof layer, so welding quality is critical; can be punctured by foot traffic or dropped tools without walkway protection; PVC needs separating from bitumen; repairs need compatible material and welding equipment.

For a small garage or extension, EPDM is often simpler. Where people walk regularly, GRP or a liquid system may be tougher. A multi-layer torch-on felt roof gives built-in redundancy, and on older buildings mastic asphalt may be the original material. Our commercial flat roofing page covers larger jobs.

What's included?

  • Edge protection on every job and walkway protection around plant
  • Strip-out or preparation of the existing roof, with waste removed
  • PVC, TPO or FPO membrane, mechanically fixed, adhered or ballasted
  • Hot-air welded seams, each probed along its full length

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
