Where did you see a picture of them laying on top? I found something
(somewhere) that shows exactly how to install them. I'll admit it's hard to
decipher from looking at the product.

It must have been the pictures on the box. I clearly remember thinking
that it might be a better idea to tuck them under, but I decided to go
with what was pictured instead.

Regardless, the warpage of the plastic suggests that it wouldn't last
many years, at least not the dark color ones, and not under the direct
sunlight here around my house.

Check out the PDF file at Amerimax.....Clearly tucked under per mfg.

There were no instructions included with the boxed set, and the pictures
were misleading, so it's odd that they have taken the time to compile a
manual without either distributing it *or* indicating its presence on
the package in some way.

Oh well, it's their loss.
