Client Problems

This multiple building site contained a variety of roof systems at various stages of their life cycles.  The challenge was to upgrade many roofs to combat the condensation from the extreme heat of the factory manufacture process. Existing rooflights and sheet laps in other roofs were damaged and deteriorating. An existing composite panel system roof was deteriorating, whilst the PV array it supported needed to remain. Other sections of metal roofs were poorly installed and leaked, these were to be over-clad. All while the factory below remained in operation with minimal interference.


Overcladding works adding 100mm insulation and a new 32mm profile roof sheet, reduced the effect of the condensation while retaining a weathertight work environment below.

The PV array was carefully removed and stored on site while a new 120mm composite panel roof was installed. Once complete, the PV array was reinstalled.

Defective GRP rooflights were removed and replaced, while roof sheets were given a Seamsil treatment at corroded edges and laps.
