Does Evergreen really need a new roof?

I'm surprised to see Evergreen Elementary school getting a new roof this summer.  The building seems new enough to me that the roof should still be good.    Not that I begrudge a new roof to the district's worst elementary school in terms of playground equipment, classroom technology,  qualified teacher's aides and white flight.  (They also have the worst test scores but can't really be blamed for that since a good percentage of the students are not native English speakers)  They need any help they can get over at Evergreen.  I just wonder if a new roof is the best use of resources.

Teacher's aide "Mary" did this to a parent, in front of  several children, including the child of
the parent, while on the clock for the Shelton School District during school function.
The next year Mary was given a full time job and promoted to president of the PTSO.
As you can plainly see, Mary is not particularly bright, but she has the right attitude
 to work at Evergreen.
