Why white
A white roof keeps the heat out
A black roof absorbs the sun's heat and passes it down into the building. A white roof throws the rays back, and you feel it under the roof the same day.
It counts for most where there is little insulation overhead and the sun is on the roof all day.
- Warehouses and workshopsWhere it gets uncomfortably hot to work in summer.
- Holiday homes and cabinsA flat roof that stands like an oven when you arrive.
- Garages, carports and sunroomsWhere the roof sits close to the room below.
The same membrane as the black. Seamless, 100% waterproof and the same lifetime, just in white.
Do it yourself
Perfect for DIY projects
Quick and easy to apply with a brush or roller, with no special tools and no tradespeople. The membrane sets as one seamless, elastic surface that follows the movement of the roof and stays watertight for decades.

What our customers say
★★★★★
I am really impressed with the quality of the Luna Roof membrane. It was easy to apply and the result looks great. Even after heavy rain the roof stays watertight.
Anders Mikkelsen, Aarhus
★★★★★
We chose Luna Roof for our holiday house and we are more than happy. The membrane is clearly robust and the 25 year warranty feels reassuring. A good investment in our home.
Lene Kristiansen, Odense
★★★★★
Really good service and fast delivery. I used the membrane on a renovation project, very easy to work with and it gives a clean, even finish.
Jesper Thomsen, Hillerød
★★★★★
After a thorough clean of our felt roof I rolled Luna Roof on. If Luna Roof is as durable as it looks, it is fantastic.
Danny Sørensen
★★★★★
I had a felt roof leaking at the joints. I spread this into every joint and it seems to bond well, so it should stay watertight for years.
Rasmus Kring
★★★★★
Easy to work with and it spreads out evenly. Easy to wash off your skin too.

Frequently asked questions
It depends on the roof and the insulation, but the difference is clearest on flat roofs with little insulation, typically warehouses, holiday houses and garages. A white roof reflects the sun instead of storing the heat, and that is where you notice it most on the hottest days.
Yes. It is exactly the same membrane with the same 25 year warranty, only the colour differs.
The surface is dense and smooth, so dirt and algae struggle to take hold. A white roof will weather a little over time, and a normal clean brings it back.
Yes. Our liquid membrane is made for straightforward DIY use. You get a smooth, sealed surface with no welding and no joints.
Applied and maintained correctly the membrane lasts up to 40 years. It is UV resistant, flexible and extremely hard wearing.
Delivery across the UK usually takes 3 to 4 working days. You get a message as soon as your order is on its way.
Yes, a 25 year warranty on the quality and durability of the product. Contact us for the exact terms for your purchase.
