Then, is Gutter Helmet worth the money?
When you compare this cost to the cost of having gutter guards installed, it should become clear quickly that gutter guards are not worth it. They are expensive, ineffective, easily damaged, and don't even do what they are supposed to do.
Regarding this, which is better leaf guard or Gutter Helmet?
The biggest difference is that LeafGuard replaces your existing gutters, regardless of their condition, and installs its own “seamless one-piece” gutter. Meanwhile, Gutter Helmet is a hood-like cover that installs over your existing gutters, usually under the second row of shingles.
Gutter guards and covers cost between $7.50 and $10 per lineal foot installed. Considering that the average home has about 200 feet of gutter, homeowners should expect to pay about $1,500 and $2,000 for professional gutter guard installation, though more complex gutter guard systems will be more expensive.
