The private flat roof owner is often helpless before the question, after the flat roof has been repaired several times using different methods and materials (roofing felt/bitumen membrane, foil/roof foil), which material is the most suitable in the long term for flat roof renovation in order to provide long-term protection and security against penetrating moisture to guarantee.


Isodach has been successfully using liquid plastic as flat roof waterproofing for industrial roofs for many years. This is where the advantages were first recognized. To seal large areas long-term and safely in short periods of time, without having to tear down the existing structure. Which ultimately reduces the renovation costs.


The enormous roof areas that isodach renovates every year make purchasing high-quality materials economical without intermediaries. Also for our private customers



Flat roof renovation with liquid plastic and fleece


When renovating flat roofs with liquid plastic and fleece, the liquid plastic as a flat roof seal adapts seamlessly and seamlessly to any roof shape and geometry and creates a full-surface, homogeneous and solid connection to the subsurface, even in critical connection areas such as skylights, wall connections, chimneys, gullies, etc. safe and durable.


When renovating flat roofs with liquid plastic, no weld seams or other connecting bridges are created, so these weak points are eliminated from the outset, which offers the flat roof sealing additional security and longevity, even in otherwise critical areas.

Our liquid plastic connects force-fittingly with the surface everywhere, meaning that moisture cannot penetrate even if it is damaged.


Weak points of old flat roof waterproofing


Conventional materials such as bitumen membrane (roofing felt), roofing foil, etc. tend to become brittle and cracked over time, especially at seams and joints, as well as in transition and connection areas.


If the flat roof has heated up significantly on hot summer days and a sudden rain shower causes rapid cooling, strong thermal stresses arise due to the high temperature fluctuations of up to 70ºC in the flat roof sealing.

With conventional materials, this can lead to cracks, especially if they are already aged and brittle due to weather.

Our flat roof sealing with liquid plastic is UV-resistant and does not become brittle, even in extreme weather.
