I can't say that rusted screw heads have been a problem with my seven year old TT. But there are other things that have been.
Your 7 year old camper is about the time screw rust can be present or just starting.
Try looking here. Pull the vinyl strip that cover the screws in the gutter rail. This is what mine looked like at 7 years living outside all the time. The water floods the gutter rail, water gets behind the vinyl strip and stays wet. Mold starts and keeps on growing. In enough time the screws rust enough water start to wick in around the screw. As time goes on the water keeps wicking in and soon rot starts.
Here is the start of the problem.
To solve the problem on a EPDM rubber roof, remove a few screws at a time, countersink for a flat head stainless screw. Do not over countersink.
Totally clean well with a high flash cleaner the gutter and 3" of rubber edge on the roof.
Install 4" wide eternabond. Start at the bottom of the gutter and go up and over the top. No more caulking exposed as the primary seal.
After installing Ebond, on the roof exposed edge of E bond, put a thin film of Dicor smeared over that edge to stop dirt sticking. Clean roof and apply 303 UV protectant 3 to 4 times a year. I have not had to touch at sealants on the roof since 2010 when I applied the Ebond. A well worth upgrade. See here from this fall. This is a 14 year old rubber roof.
Hope this helps
