Garden office application with felt

Can shed felt be applied on top of this using bitumen adhesive?
Asked by: Rob85

Hi, can i use this felt under a natural slate roof?

Asked by: Anonymous

My garage roof currently has felt shingle tiles and leaks slightly (more so in the wind). Would this product work as an underlay as well as or better/worse than underlaying with normal felt?

Which Adhesive?

Need to cut in around a dormer window on a timber summerhouse then use shingles too finish. Would need to use an adhesive/ bitumen based product to rejoin all the cuts etc to prevent water ingress. Which product is suitable please.
