We ship from our own warehouse in Denmark. The UK charges import VAT and duty on parcels from the EU, normally about £60 per shipment, and the carrier collects it from you when the pallet arrives. It is not part of the price you see here.
That is why the price is down to £295.00. The reduction covers most of what you pay at the border.

What our customers say
★★★★★
Saved me from a full roof replacement. I was quoted thousands for a new roof, but this sealed everything over a weekend. No leaks since, even after heavy rain.
James, Manchester
★★★★★
Used it on an old flat roof with several cracks. The membrane covered everything in one seamless layer. Months later, still no problems at all.
Daniel, London
★★★★★
Thick, easy to work with and gives a clean finish. It genuinely feels like a professional grade product, without the professional price.
Chris, Liverpool

Used this on our shed roof in Manchester. Easy to apply and holding up well after several rainy days.
