Is this old mortar from underneath roof tiles? (hoping not asbestos)

Hi everyone, would really appreciate some advice to put my mind at rest.  I have a 1930s semi with the original roof and red tiles.  I decided to venture into the loft to have a quick look after the recent storm to make sure all was OK.  On opening the loft cover I got covered in what I think (and hope) was old mortar.  Looking in the roof void there's no felt on the tiles and it was very dusty.  I could see what looked like mortar on the edges of the tiles, but mostly it had dropped off with lots on top of the insultation.  I'm a bit paranoid about all things asbestos with having kids in the house and taking a closer look the mortar looked like it had hair and even twigs in it.  I've posted a couple of pics, I'm guessing asbestos wouldn't have been used in this way at this time? When the space was re-insulated in 2013 the company never mentioned asbestos and neither does the home report from 2011. Advice most welcome.  I could pay for a asbestos test but I feel a bit daft as a friend said it was definitely mortar.

Known as torching, was usually a mix of lime mortar and horse hair.

Yes, my 1930 house had a roof just like it so don't worry, it's not going to be asbestos it's mortar

Also just read that lime mortar fizzes with vinegar.  Did a little test and  a small sample fizzed like crazy.  Thanks so much for the replies.
