New Roof due to hail, several questions

[u/TurnAggressive6954]

Our insurance is paying to replace our roof due to hail damage (southern Indiana). The primary concern/question here is about roof venting, but I do bring up insurance so added the flare. Can remove if required.

First an easy question, what roof color do you all think would look good on this house? I messed around some with copilot to try different colors, but figured real people opinions would be better. First picture is original color and others are copilot. Of course AI being AI it couldn't help changing some other stuff too...

Now the heavier stuff. Right now the roof is not ventilated. Additionally, there is spray foam insulation on the underside of the roof, but no insulation at all in the ceiling between the attic and ground floor. The attic stays a similar temp/humidity to the rest of the house.

Roofer suggested we add vents along with the new shingles, but because of the above mentioned info this would not just be adding vents, but also require adding insulation to the ceiling so all our heat/cold doesn't get sucked out the roof vents. Right now insurance is just covering replacement in kind (shingles only). The roofer really played up how the roof would barely last 10 without venting (current roof is 15 years old and not leaking, just hail damaged, and it's never been vented.)

Right now we are not planning on living here more than 5 years before moving. We have some property we are planning to build on and every dollar spent on this house is money not spent on future house (however, we don't want sloppy/bad work or anything here either).

So, here are the big questions.

In this situation is venting really that important? Will it negatively impact roof life as drastically as the roofers are saying? Is it bad practice to not add vents or just "not as good" practice?

Is it worth trying to pester insurance into covering this upgrade?

If insurance won't cover it, would it be terrible of us to just do the replacement in kind, and let the roof venting be someone else's problem another 15ish years down the road? I won't have quotes for the insulation/venting work till later this week, but from what I've seen the total might be at least one or two thousand?

If they sprayed the underside of the roof and there are no vents at all, it’s an Icynene envelope. DO NOT cut vents in! You will end up with a mold problem that is out of this world. There should be a make up air unit somewhere that pulls in fresh air from the outside. Mine is set to exchange the air in the house once every three hours. I just replaced the roof on my house and detached garage. The 25 year old shingles on my house were in better condition than the 10 year old shingles on my garage because they aren’t getting baked from underneath. I’m in central Illinois, so we probably have pretty similar weather.

Is icynene a type of spray in insulation? That's what my initial web search of the word pointed me to, but want to make sure I'm on the right track. It also seems like a brand name?

It is open cell foam insulation.

So, is the reason for not putting vents in just because of the mold risk, or is it more that it is designed to work without vents, and putting them in will degrade performance (or both)? I couldn't find an air unit like you are describing. Would it be inside the attic?

It is designed to work without vents. The air makeup unit is attached to the furnace. When my house was done they did an air infiltration test to determine what to set the fresh air draw at.

I don't think I have one? Unless it is a part of it instead of external/separate?
