Your explanation is very thorough but it is still a bit difficult to picture and address this digitally, but hopefully I can help. From what I can gather, any gap like this could be a problem down the road. I can't quite understand why the builder would do this and my hope is that there was some reason besides oversight or poor planning. Ideally there will never be a gap in the fascia because as soon as water gets inside there, it can cause rot or mold or other defects that can really damage a home. Can you see these gaps or do you know they exist and were patched over? Because especially if they are still visible, if you can see it then water can get to it and likely will over time. For the 1/2 inch gap I might even worry about small animals getting in there and causing problems also. If there are layers over the gaps and they are sealed well then hopefully that is sufficient and you can avoid putting more money into this.

Again, this is the best that I can understand and hopefully there is no serious problem moving forward. Sorry to not have a definitive answer but I hope that is some help. You can call Steve and talk more about this to clear things up and feel free to ask for me directly if you want as well (513)724-0539.

Thank you so much for the very informative video.

I have a question regarding the fascia on a roof remodel. The builder extended the rafter tails to create an 18" wide soffit. At one exterior corner, the fascia has a 2" gap where the side of one fascia board meets the side of another fascia board. Ice shield was installed over the fascia, and drip edge was installed over that, with the shingles on top. The builder says the gap will not cause any problems. Do you think he is wrong?

Also, there is about a 1/2 inch gap between the roof sheating and the fascia. The ice shield covers that gap. When snow was melting off the roof I did not see any water dripping between the fascia and the drip edge. All of the water seemed to be dripping off the drip edge into the gutter. Do you think this gap might cause problems in the future?

Thank you so much for answering my question. You have no idea how much I appreciate and respect your input.
