Case: 150 m2 corrugated iron roof in Copenhagen, before and after
Tobias' roof is located on a property in the middle of Copenhagen. The roofing felt was still intact, but the surface was worn gray and there was moss and lichen in the fields around the joints. This is what a flat roof looks like after a number of years: it's not leaking yet, but the joints are where it starts.
Sealing instead of replacement
Instead of tearing the roof off, Tobias chose to have it cleaned and sealed with Luna Roof roof membrane. It is applied with a roller directly on top of the existing roofing felt in one layer and lays down as one continuous surface, without joints and without seams or welding.
A roof of 150 m² corresponds to 12 buckets, when a 20 kg bucket covers up to 13.3 m². The before photos are from 29 and 30 June, the after photos were taken on 4 July.
The result
The surface is now uniform and closed all the way, also over joints and transitions. The membrane is elastic, so it follows when the materials work in heat and cold, and it is UV-resistant, so it does not become brittle from lying in the sun.
If you want to calculate your own roof, you can enter your m² on the product page and see the price immediately.
The membrane from the case is ours liquid roof membrane, and on the product page you can calculate how many buckets your roof will need.
