The application of new shingles on an old roof, nullifies (voids) the warranty. In the warranty of the seller he should have made it clear, that the roof was a lay over. HOWEVER, check your local codes!
You may seek claims in a small claims court from about $1k up to over $20k in some states.
example of codes:
“New roof coverings shall not be installed without first removing existing roof coverings where any of the following conditions occur:
Where the existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing.
Where the existing roof covering is wood shake, slate, clay, cement or asbestos-cement tile.
Where the existing roof has two or more applications of any type of roof covering.
For asphalt shingles, when the building is located in an area subject to moderate or severe hail exposure..
In MY opinion, in this case if the roof needed repair, it needed removal first.
