Found this installed on a roof today but can’t seem to find anything about it. Hopefully you can see from the pictures this is a composite and not rubber which I first thought. It is installed over the asphalt shingles(one layer and a flashing has been installed inbetween. Could not see any major issues with it but just don’t know what it is or how to age it. Did not walk the roof as it seems pretty fragile. Any help would be appreciated.
No one has produced them in North America for quite a while. Best to tell the client that there was a class action lawsuit, now closed, that the roof may need to be replaced soon, and evaluate the roof-covering material visually on an individual basis.
