Quenya and other Tolkien's languages' <ss>

Does <ss> in Quenya represent geminate /s/ or is it just another
orthographic quirk to adjust the appearance to English spelling (like the
diaeresis on e)? Or is it just that /s/ is often long in these languages
since <ss> is very common? Being it just a way to write single /s/
somewhere would be pretty confusing since these languages have consonant
gemination (<nn> = /n:/, <mm> = /m:/ etc.).
