Nope- that is the roof.
As I previously stated, I had that exact type of structure on a previous house. Look closely, there is a seam every 16-18", that is where that structural flange is on the exterior side. The top of the flange is a lap joint that is pinched together with a roll-pincher- making the seam weather-tight.

That oxidation sure doesn’t say weather tight, but I see what you’re saying. I had to pull it up on the laptop to get a better picture (damn aging eyes). Based on all that, it would surely need to be insulated and finished from the underside. Possibly sealed as well above since there appears to be a lot of moisture (could be condensation/humidity).

Putting another roof on top of this one though? Sounds kind of ludicrous to me.

IIRC, when my neighbor had to replace his Florida room after one of the hurricanes... Wilma?... Code required plans for approval and there was a type of approved SIP that was used. I don't think this is it, but it was similar.

What is ludicrous is the continuing fascination with trying to attach cheap foamboard to a grandfathered cheap roof and being frustrated with the OP for not doing it. It is a waste of time, money, and a sure way to get a HOA into a hornet nest frenzy. By the time fines and legal bills are paid, TWO new Florida rooms could be built for the costs incurred. A non-attached ceiling that is similar to a kid making a fort out of a card table MIGHT squeak by for a few months, but even that is a possible waste of money (without the fines).

Show the bylaw it violates. Not your assumption, the one that actually applies.

I knocked down ambient temps 10 degrees and “real feel” about 12-13 with changes I made with “cheap (what the OP was actually looking for) foam board - Lo
And behold, no frenzy.

Show the bylaw.

Tell ya what. Show me a listing of all HOAs in Florida, a current online PDF website showing all the bylaws, and determine which HOA is involved, and then,maybe, I'll waste MY time.

Oh yeah, AND live in Florida for about twenty years to have an understanding of how a HOA board will act totally capriciously and how long various building materials last.

I've done my share of redneck engineering, and yeah, foam can cut heat transfer. I also know not to tempt retired NYC control freaks with nothing to do but make the lives of others total h e double hockey sticks.

Show me:

1. Wherein adding insulation to a screen porch roof is “redneck engineering”.

2. Pick any HOA at random and find where you could not add insulation to a SFH.

My point was that:

1. It works, it’s proven to work, it makes no material change to the structure or requires a permit.

2. Absolutely nobody has been able to state where an HOA would have any restrictions that would disallow this.

3. I’ve actually done this in a FL HOA neighborhood.

Seriously. Some of the dumbassery and assumptions in these threads sometimes… don’t people ever read?

What about the insulation from the inside of this house extension rather doing it from the outside. The insulation will make it cooler in the summer and cozy in winters.

I didn't read every page, so forgive me if it's been suggested, but Conklin (and probably other manufacturers) makes a spray-on roof coating that will measurably reduce thermal transfer. It looks like spray foam when it's applied but is engineered to be used on roofs.
