The choir and sacristy are the oldest parts of the church, from circa 1300, while the nave dates from the middle of the 14th century.

No major alterations have been made to Väte Church since the Middle Ages.

The exterior is partially decorated with Romanesque sculpture (the northern portal, decorative reliefs and window dressings), and has two Gothic southern portals with finely sculpted capitals.

One set dates from the 14th century, another by the so-called Master of the Passion of Christ (Passionsmästaren) from the 15th century and a third by the so-called Master of 1520 (similar to murals in Alva and Lau churches).

The church has undergone restorative works three times during the 20th century: in 1927–28, in 1956 was under the direction of architect Nils Arne Rosén (1920–1998) and the work in 1965 under architect Olle Karth (1905–1965).
