Should you remove icicles from your roof?

Accepted Answer

It can be dangerous to remove icicles from your roof, so the best option is to treat the underlying issue instead, usually by ensuring proper insulation in your home. If you’re concerned about immediate damage, you can hire a professional to remove the icicles and the snow accumulation on your home to prevent the issue from recurring. Just make sure you use a long-term solution, too, like addressing insulation problems or installing roof heating coils on your roof.
