We have removed our old gutters and do not intend to replace.
There is a space between the fascia boad and the subroof -
What can we do or use to close this gap??

Install new gutters?
:D

Maybe you can put on a new fascia board in addition to what you have, can you post a picture so we can see what you have there.

You can probably find a large vinyl or aluminum drip edge that would cover the area but matching the looks may be difficult.
