Question about "Florida Sunroom" style ceiling

Our sunroom is about 20 years old here in Southern Ontario, Canada. It is a 4-season modular style sunroom made up of four-foot panels and is, in total, roughly 20 x 12 with windows along the three sides. The roof panels are about 4" thick and the ceiling has - to my knowledge - never leaked along the seams. (though it had leaked for a short while between where it meets the house)

We recently had the roof shingled over a plywood base, but the issue I am having precedes that.

One of the panels - at the seam - seems to be becoming disconnected from the adjacent panel. It is not leaking, but we are getting what appears to be a brown styrofoam kind of dust coming down from it.

It looks like they should just click together.... but they don't seem to.

Any thoughts on what I could do here, based on a knowledge of what I am working with and how these things fit together?

I assumed the skin on these panels would be aluminum, but one person who came over and tapped on it with his fingernails seems to think that, despite the places where it is corroding a bit, they might actually be plastic.

We were originally thinking to drywall over it, but it doesn't appear that there will be anything to affix strapping to. Even if we could just fasten it back into place that would be okay.

Thank you!

From what I'm seeing..... the outer covering is stamped metal..... probably aluminum.
They appear to interlock when installed.
I don't know how you'd slide them together now once they're installed.

You said you had the roof shingled over a plywood base.
Was the base installed over the existing roof ?
Typically this style of roof is not shingled.

I would use a block of wood & hammer and see if you can get the panels to snap back together.

No, I would not sheetrock. You've already added the weight of wood sheeting and shingles which it probably wasn't designed to carry. Adding sheetrock would be even more weight for it to support.

Look into the gap show in photos #1 and 2. What is the core of your ceiling? It is probably either foam or a paper honeycomb. When you push on the area in photo #3 how does it feel? Does the skin feel detached from the core or is it solid?

HI there!

First, thank you both for your replies! I’m going to have to update my preferences so I get email notifications more than once a week. :-)

PJMax - yes, your description sounds like what kind of construction this is. The original roof that the plywood base was installed over was a metal sheeting.

Before we got the roofing put on, we had a leak where the sunroom attached to the main house structure. I went to a company called QSI who, around here, is kind of the gold standard for this kind of sunroom. They put shingles on plywood on their roofs all the time and even had some samples in their showroom like this. When I asked the roofing company about it - yes, a reputable one - they confirmed they have done those with no issues.

Hopefully they were not misleading me.

As for weight, I do want to be conscious of that, of course. I know that it is not terribly unusual to have a foot of snow on these roofs around here from time to time, but the weight of the snow plus the roofing plus hanging drywall on the underside is probably inadvisable. I can certainly see that. Not to mention that there doesn’t seem to be anywhere to affix drywall to anyways.

Pilot Dane - thank you too…. I can push the edge of the panel up so that it is flush with the neighbouring panel. The two parts just don’t seem to line up so as to snap or click together. Duct tape is almost enough to hold it. Almost. Not that that looks great. At least it’s white. Haha.

I’ve shone my flashlight into the gap but can’t really see anything - just what is shown in the first photo. I’m reluctant to pull it apart any further. The material that sprinkles down can best be described as brown cellular particles…. I would guess styrofoam dust. I don’t think it seems paper-like.

Pushing on the ceiling, it feels quite firm and solid, except of course for where the one panel is sagging.
