I have also found my wild species roses are a great trap crop for Japanese beetles, if you have those in your area.
Like many here, I grow rugosa rose and have found it to be tough as nails. It's propensity to root sucker is both annoying and useful: requiring frequent attention if I don't wish my bushes to turn themselves into thickets, but also providing an endless supply of easily transplantable new roses. But, I don't know how much the hybrid tea roses the OP inherited with her land will follow this same pattern. I will also note that I was skeptical at first how well they might do in my heavy clay soil, since rugosa famously enjoys sandy places (I've read it is known to colonize beach dunes). They go crazy here! I think the take home lesson is that if you want a surefire, rapidly growing, rapidly spreading, and early producing species to jump start a bare patch on your property, wild roses are a good bet.
So, the question remains: should you maintain your hybrid roses or replace them with other species, including possibly wilder rose species? I would say give it time and let the roses tell you what to do with them. Give them no chemical care or overmuch attention and see how they respond after a year or two. If they continue to thrive, then you have learnt something about them, and you have enjoyed some free visual appeal to your otherwise empty lot while it is in its early establishment phase. As the rest of your systems mature, you will see how these roses fit into your growing landscape: whether their size and position are convenient for you or not. You might then chose later to replace them with some even more hardy and productive wild rose species if you found they were in a good spot. If they don't survive the neglect, then your decision has been made for you.
UPDATE: Not long after I wrote this post, my own various rugosa rose thickets began to die back. And this, as I'd originally pointed out, after 4-5 initial years of rampant, seemingly unstoppable growth. The first year of trouble was a drought summer, so that might have had something to do with it. But then in subsequent years they continued to decline. And in all areas of my property at once. Now I have only a few straggling suckers left.
So far I have not attempted to replant them. Given that people say rugosa are incompatible with my soil type, I took their eventual die off as a sign that they shouldn't exist on my property. I might relent and give them another try one day, but only if I don't come up with something else to attempt in those spaces first. One of the two bigger spaces I've already used to start a pineapple guava.
