No felt under metal roof over rafters

Postby Jlynx » Sat Oct 16, 2021 4:22 am

Hi, I need advice please.
My roofers installed new metal roof in my absence and did not put felt over the rafters. I am using box profile steel tile sheets. The kingspan insulation will go between the rafters and underneath, but I am really worried that there is no waterproof membrane between metal sheets and insulation. Also, I am concerned about rain noise as felt would offer some soundproofing.
Do I have a reason to worry, or is it ok? What can I do now to improve the situation?
Any advice appreciated.

Hi jlynx
Suggest you find out the manufacturer of the roof sheets and contact their technical department.
