Can I use tar paper or old roofing shingles to keep weeds and grass from growing?

Although both products you mention are effective in blocking out light and holding down weed growth, I advise against using these materials, because they can contain chemicals that leach into the ground and adversely affect your plants. Instead, use sheets of newspaper covered with mulch, or landscape fabric. Even black plastic (covered in mulch to make it look more attractive) is a safer alternative.
