So have a look at this new EPDM roof the owner of this property in London contacted me asking me to insulation the roof.
When I looked at the photo he sent me I told him the bad news
Where are the flashings?
The customer told me that the roofer was cheep he completed the roof by getting access from the skylight?
Apart from the fact the flashings are missing or they are using the old flashings, the EPDM rubber has been laid over the old roof without any insulation.
Capping a flat roof is not necessary a problem. Whats capping you may ask?
Capping is when we place a flat roof membrane over the old roof covering. ( we don’t strip the old roof covering)
But placing a black flat roof membrane over an old tar based roof such as mineral felt is not a good idea
First the heat transferred down through the black of the EPDM will belt the old roof
Secondly the room below will be like an oven in the summer
Hopefully I will be posting how we insulate this roof in a later post
So until then
