I have a small barn like structure on the back of my property that I have started fixing up. Previous owners have done stuff to it as well and I came across this part in the loft. As can be seen in the pictures this light shining through into the inside from the soffit/facia, if that's what it would be in this scenario.

What I am wondering is, is it okay to seal that up? From the other side of the structure, it looks like they are mostly boarded up. I want to try to keep the place at a somewhat decent temperature so I would like to seal it up with some foam to keep spiders and bugs out.

Let me know if you need any more info or pictures. Also I do know about the moss on one side of the roof, that side doesn't get much sun and I live in a wet climate and it has like 3 large trees surrounding it.

I own a small business and am currently using quickbooks, however I don't really make enough to justify the price I am paying for it. I did have a deal for roughly 3 months which made it cheap, however the price has gone up now.

I was wondering if anyone knows of any self hosted applications that support business like tracking. Would something like firefly work for this? I am not really needing budgeting.

I had a skylight in a small barn I have on my property which had a branch go through one of the plastic bubble like skylights. I have been trying to find a replacement for it but can't find any that match.

It doesn't need to match the old one but everything I find is flat around the edges or pre-flashed. Anyone happen to know the name of what was previously on there where it has sides on it too?

Here is a picture of the skylight hole itself. The dimensions are
Inner - 21 inch 3/4 x 21 inch 3/4 Outer - 26 inch 1/8 x 26 inch 1/8

I found this after I posted, so I guess it is called Dome over Frame but can't seem to find any online.
