I really want to redo my roof and gutters, I've been trying to decide if I should use a company like this (http://www.gutterhelmet.com/) too, does anyone have advice? I would really appreciate if you could shed some light on this subject. Thank you!
Any seamless gutter company can install gutters that will look better, far less chance of leaks then some DIY install.
As far as something like the ones with gutter guards, depends on if you have a problum with trees to close to the house and what type trees you have.
If there's no tress then any 5" gutter will work and save you a ton of money.
If there pine trees I've never seen a gutter guard that keeps them out.
