C19 tile roofs, with crested ridge tiles to porch.
EXTERIOR: The exterior, despite being of the C17
C19, is in the Decorated style of the early C14.
The chancel is an important Gothic-survival work, with a bordered stone over the east window inscribed 'AN:DO 1633'.
The studded door is probably also of 1633.
The outer bays have small round-headed Norman windows, and the central bay is blank (the former doorway is only visible inside).
A sill band is on the nave north wall, where there is a round-headed blocked Norman doorway.
The chancel retains its 2-bay hammer-beam roof of 1633, incorporating primitive terms beneath the hammer beams.
The roof rests on big stone corbels, carved with mythical figures including a unicorn, Pegasus, eagle and lion.
The panelled dado in the east wall, continued above the choir stalls on the north and south sides, is also probably of 1633.
The chancel has a C19 tiled floor, with richer decorative tiles, including encaustic tiles, in the sanctuary.
A painted Victorian Royal arms is above the west window.
On the south wall of the chancel is a memorial to Francis Billingsley, killed defending Astley Abbots in the Civil War, in the form of a rectangular tablet with inset slate inscription panel and painted armorial badges around it.
In the nave north wall is a marble 1914-18 war memorial tablet.
Only 2 windows have stained glass.
