Lead on Flat Roofs Oxidising

The lead on these flat roofs is beginning to oxidise and break up before the end of its lifespan. Lead on roofs and flat roofs are supposed to last 30 to 60 years with very little maintenance. What we see more and more is lack of ventilation and roofs sweating; this problem is happening because of the lack of ventilation under the lead flashings.


Kemperol Self-terminating System

Kemper is a liquid flat roofing membrane, it is not an EPDM rubber liquid. Kemper is a liquid resin that’s impregnated into a fleece fabric to give it depth and strength. As it’s a liquid flat roofing material it is easily applied to roofs with lots of detail on them. If we were to use a sheet roofing material e.g., sheet EPDM rubber, we would have to cut and patch the rubber in lots of different places, thus taking away the properties of using sheet materials.
