So we got these foam inserts then realized they would not fit correctly. Any ideas on what I can do to seal up these gaps/holes along the front and back edge of our roof? I used some silicone caulk along the edge so that will seal where it is flat, but I'm unsure of what sort of products would best get the job done for a gap this large. I already have vents for ventilation, and would like to close these roof gaps off to keep things warm enough in the winter especially, and to keep water out. Ideas?
