Silver maples are one of our commonest fast growing weed trees.
Any city with a large population of these trees has rather high

Considering the size and probable condition of your trees, it
would be prudent to plan the removal and replacement as soon as
you can.

That is complete bull**** advice.

The truth is that people don't live long enough, and certainly not in
the same home, to see a "more desirable" replacement tree grow into
maturity.

I have two silver maples (each about 2 ft diameter) one in the front
yard and one in the back. I have seen what high winds (and even extreme
snow events in October - BEFORE they drop their leaves) can do to them
over the past 10 years - and the truth is not very much.

Until we can buy mature trees at Home Despot and "install" them as
easily as we can buy and install a hot tub or a deck or some other
relatively expensive piece of out-door infrastructure, I suggest you
treat any existing mature trees on your property as the only ones you'll
ever have in your lifetime.
