My home has a fiberglass roof deck with parapet wall surrounding it. The parapet wall is covered in aluminum (at least I think its aluminum) that matches the vinyl siding and color of the fiberglass roof deck. There are distinct sections that cover the parapet, and at the seams - in most places - there are small ~3" wide covers. You can see one in the photo here:
When we bought the house, for some reason about 4 of these were missing. Which is very strange because we are in a row of 5 houses, all exactly the same, but only our house has these missing, and it's only on the very front wall. So they now look like this:
And here you can see both a missing one, and others that are in place:
How can I go about getting something to replace the missing caps? They seem to be aluminum (though I'm not 100% sure). A roofer told me to ask at a building supply store, but they were totally baffled. I can't seem to find anything like this online. In fact, I'm having trouble even figuring out what the call these things. I've found a handful of terms in my research, including:
- Joint Cap
- Cap Flashing
- Cover Plate / Cover Strip
- ERC Strip (no idea what that stands for)
- Slip Expansion Cap
- Slip Cleat
- Drive Cleat Expansion Joint
But I don't know if any of these are the appropriate term for what I'm looking for, and I haven't been able to find anything that would work to replace these. I'm unable to find any markings on the siding or elsewhere to indicate who might possibly make these (I'm guessing something like that would be under the siding?). I'm at a complete loss on how to replace these things.
Does anyone have any idea how I might find something to replace these? I don't even care if the color doesn't match, because anything would look better than how it looks now.
