A composite roof panel for flat or low pitch roofs comprises a generally flat external sheet (2), a profiled internal decking sheet (3), and an insulating core (4) between the external sheet (2) and internal sheet (3). The external sheet (2) has an external male projecting part and an internal recess part on one side for engagement, on assembly, with a corresponding external recess part and projecting inner male part respectively on the opposite side of the panel. At least a portion of the side edges (21, 22) of the insulating core (4) between the joint forming portions of the external sheet and internal lining sheet has an inclined wedge profile. The inclined wedge profiles of the side edges (21, 22) of the insulating core (4) form oppositely directed wedge faces. A side edge (22) of the insulating core (4) of one panel (20A) is matched with the opposite side edge (21) of an adjacent panel (20B). On assembly, a first overlap portion of the panel receives a second overlap portion (31) of the adjacent panel. A joint reinforcing plate (40) has a downwardly extending locator defined by a projection (41) which is located in a gap at the joint to ensure that the reinforcing plate (40) is accurately positioned relative to the joint. The plate (40) has holes to receive joint fasteners (44, 45).
