Do you NEED a fence? The yard you're standing in to take the pic doesn't have one. How about a low hedge?

Are those Bradford pear trees in the yard? It looks like they are by the shape. If so, when you take the fence out, have the trees removed before you put up a new fence. Bradford pears (Callery pears) are very short-lived, and they look to be the right size that they are at the end of their lives (weak trunks, bad branching that leads to huge sections splitting off).

some ideas

A more modern (and transparent ... and expensive) fence would be metal pickets. If the fence that's there now is in good shape but just needs improved appearance, painting it white or very light grey would help. Brown makes it look like it's trying to hide. But, of course, it can't.

Please consider the above comments re the Bradford pear trees seriously. These trees are notorious for weak limbs and they do indeed look as if they are near the life span. Talk to a local nursery about appropriate choices for your climate zone. I'd forget about the fence and spend the money on replacing your trees.

Do you need the fence for privacy or containment for animals/small children? If not, I'd tear it down and not replace.

I would consider another option that was mentioned above, do you need a fence out front?

Yup. Sure look like Bradford pears. The one next door to me has split twice and once lost 1/3 of its mass in one big crash onto a couple of cars. They might last 20 years, but that's it, and when they go it's spectacular, sudden, and damaging.

The city (Philly) won't allow them to be planted any more along the streets.

If it were mine I'd replace with full height chain link and plant it with suitable climbers. In addition to having concealing shrubbery planted on my side of it.

Because I would not want to be open to the road. Nor would I want to have Callery pears in my yard. Esp. at flowering time.

If you remove the fence, do you think the knockout roses will be harmed somehow? Or someone will steal the roses?

Let the roses BE your fence.

A full height chain link fence? In front of a house? Classy idea.

Maybe in a trailer park. In West Virginia.

Do you really think she came in here looking for that as a solution, embothrium?

I think a hedge is the way to go. I love roses and have a hedge of David Austin Princess Anne roses is gorgeous in the summer and just fine in the winter.

Chain link is never a good look, especially in a front yard.

A lower stone planter to match the stone on the house?

Remove the fence entirely and use the existing roses as the foundation of a natural hedge divider between your property and the street. Nothing weird about them and you can fill in (behind?) with other shrubs to add more seasonal interest.

Have to wonder at the suggestion of chain link........here, when needed for security for pets, etc., hogwire fencing is used in place of chain link. A far better look aesthetically. But if you do not need the fence to contain pets or for privacy, then get rid of it altogether.

A lot of modern fencing ideas are available. You can go for horizontal slats or modern dark fences. Look up this houzz ideabook for some interesting ideas: https://www.houzz.com/ideabooks/106492784/thumbs/top-8-modern-wood-fence-design-ideas
