Just the basic information you need.
Roswell High was originally developed by 20th Century Fox Television and Regency Television for the Fox Network, though it eventually landed on The WB (retitled simply to Roswell) thanks to the latter network's offer to extend a full 22-episode upfront commitment. The pilot episode was filmed in 12 days with a budget of $2,000,000. "The Morning After," the second episode of the series, was the first episode with the full title sequence utilizing the theme song, "Here With Me" by Dido.

The series premiered on October 6, 1999, on The WB Television Network in the United States to generally favorable reviews, and it quickly gained an outspoken fanbase.
In response to the problems the series had with ratings during its first season, the relationship-driven stand-alone episodes of the early first season were to be replaced with more science fiction themes and multi-episode plot arcs. Starting with the second season, after a fierce fan-driven campaign involving bottles of Tabasco sauce—a favorite condiment of the show's alien characters—being sent to the network's offices, veteran science fiction writer Ronald D. Moore was brought in to join Katims as an executive producer and showrunner and to further develop the science fiction elements of the show.
Not all fans responded favorably to the shift to more science fiction-driven storylines during the second season and the ratings continued to disappoint, causing the network to finally cancel the show on May 15, 2001, after the show's second-season finale, a move widely anticipated due to the sagging ratings. 20th Century Fox (the studio that produced the show) was able to persuade UPN to pick it up for a third season as a package deal when UPN outbid The WB for one of its popular flagship series, Buffy the Vampire Slayer. During the 2001 - 2002 television season, Roswell, in its third season, aired directly after Buffy on Tuesday nights on UPN, though it was unable to hold on to the audience Buffy provided as a lead-in. This eventually resulted in the show's cancellation from UPN as well.
