Inspecting the roof structure
Before battening commences, the main contractor should make sure that the rafter/truss centres do not exceed those recommended for the batten size. The roof structure should also present no abnormality, thereby offering an even plane for battening and tiling.
It is strongly recommended not to proceed until the structure is approved.
It is unlikely that a roof previously covered with other materials will have the correct structure to carry concrete tiles. A comprehensive assessment is therefore essential and proper adjustment and reinforcement of the structure must be done before laying concrete roof tiles. It is always advisable to contact your nearest MONIER Roofing outlet for expert advice when considering a re-roofing job.
