The 19-year-old right-back has made the move from Daisy Hill after impressing manager Lee Ashcroft in pre-season.
Ashcroft told the Town website: “I'm delighted to have signed Jacob, he's a great young lad who I'm looking forward to working with.
“He’s really impressed me in pre-season and it's great to have him on board.”
Ridings is the first addition to a squad looking to build upon last season’s fine performances in league and cup.
Having reached the last 16 of the FA Vase, Town were also in the hunt for promotion from the North West Counties League’s top flight when football was brought to a halt as a result of the coronavirus pandemic.
For his part, Ridings added: “I can’t wait for the season to get going.
“The team is full of quality and I can’t wait to be a part of this squad and hopefully achieve great things.”
