I ordered some roofing felt and battens from my local builders merchant, as they were delivering other wood at the same time too. I'm surprised by the felt that's been supplied - it as tiny stones on one side - the kind that you normally see used on a flat roof. I think I expected it to be plain black on both sides.
Does this matter? My intended use is on a ~30 degree pitched roof under interlocking tiles, with insulation in between and over the joists. The felt is 'Green Mineral Felt, Rose roofing, 10Mx1M, Ref 38'
Thanks
