I saw an ad on TV for "Austin Gutter King" where they took the shingles and
picked them up to slide a gutter-guard in. It sticks out far enough to block
leafs from getting in the gutter. I've seen these at Lowes and they are
really cheap.

My question is: Wouldn't that cause a problem with the shingles?

My neighbor had some gutter-guards like that but when the roofing co.
re-shingled the roof they didn't put the guards back in. I figured they
wouldn't guarantee the roof with the guards installed.

Anyone know if that is a fair assumption?
