Is "read roughly" a natural response?

Solution 1:

roughly relates to quick estimates or drafts of a document (e.g. a proposal). What you want to give is a quick, first impression kind of reply.

There are different ways to say this.

At first glance, it doesn't seem to be what I want/need.

This implies, however, that you might give it a second glance. If you don't, you can try:

• After skimming this, it's not quite what I want/need.
• At a glance (or, I glanced at it;), it doesn't seem to be quite what I want/need.
• I scanned this, but it's not exactly to be what I want/need.
• I did look it over; it's not quite what I need.

Solution 2:

Try using, "I skimmed the contents, and it's not what I had in mind."

Or

"I grazed the contents, and it's not what I had in mind."
