EPDM heat resistant?

[JBR]

I have an extension, including garage and en suite bathroom, whose roof is leaking. Although slated, it has a very slight slope of less than 15 degrees. I realise that slates are unsuitable for such a shallow slope, but it has been like that since well before we bought the house. Needless to say, it is leaking and the leak is getting worse.

I had thought about having the slates replaced with boarding and EPDM covering. The problem is that there is a combi boiler flue in the middle of the roof. Would the heat from this melt the EPDM?

Not if the terminal is as high above the roof as it should be, and surrounded by a suitable lead slate.

Thanks. I am assuming that you are referring to the plume. The outlet is about 4 feet above the surface of the roof. There was no mention of a lead slate, but I could ask the roofer.

Actually, I was thinking more about the heat from the body of the flue, although if I recall the inner pipe is for the hot outlet and the surrounding pipe for the air inlet.
