I bought the vinyl gutter guards and started installing them. I cannot
get them to "snap on" to the edge of my gutter. I wonder if there are
other kinds of guards and I purchased the wrong one. I've included
pictures of my gutters and how the guards lay on them. I'm a little
worried that a brisk wind will blow them off because the only thing
that is holding them to my roof are the shingles. Are there special
clamps i can buy to secure them better? the bottom of my gutter is
rounded so it will be a challenge to get a standard clamp to attach to
it.

Also parts on parts of my roof the shingle are very hard to pry up and
I cannot get the guard far enough under because there is a nail or
something blocking it - what do you suggest in that situation - cutting
the guard so it's more narrow?
