Hello,
I have two GRP flat roofs that are failing due to poor installation and need to be replaced, including the build up. They are each about 25m2 and have a large roof lantern in the middle. The lanterns are wood and a pain to remove (impossible without damage). I am concerned about using GRP again given our bad experience so I want to look at other options too, such as EDPM. Would it be impossible to re-roof in EDPM without removing the lanterns? They sit on an upstand so it wouldn't be possible to bring the EDPM up over the top with the lanterns still in place. Any thoughts welcome please.
Thanks
