PaulaLawrason is correct! Roofing paper is impregnated with asphalt. It will leach into the ground and contaminate it. Bad for plants, especially anything edible.
@MN Mom I understand. I too have been feeling the same. You have been one of the top contributors to Hometalk. It has been great connecting with you.
Thank you so much @William! Contact Hannah and Miriam at Hometalk and let them know how you feel. Best wishes! I'll check in with you later!
