Technical info

Only since October 2010, has it been officially possible to put a solid roof onto a conservatory or porch.

In August 2013 the Local Authority Building Control (LABC) released a circular containing some basic guidelines relating to Building Regulation Legislation which apply to the replacement of a translucent roof ( made from glass or polycarbonate) onto a conservatory or porch with a solid roof.

The Guardian™ solid roof is a strong, lightweight tiled roof and is fully approved by the Local Authority Building Control.

To comply with part L of the building regulations 2010, all roofs to rooms (except those in unheated buildings) should be thermally insulated to a maximum U-value of 0.18 W/m2K.


The building as a whole must be structurally sound. Any alterations that affect the original structure must be carefully considered. The foundations must be checked to ensure their suitability for an increased loading. The conservatory window framework must be assessed also and the new roof structure must be proven to be structurally sound.


Guardian™ roof Fitted in 2003

Recent additional work to an eleven year old Guardian™ roof meant that the tiles had to be stripped off. At the same time we thought that it might be the ideal opportunity to inspect the original breather membrane and ply deck, to determine if there had been any deterioration over this period of time.

Proof indeed that the Guardian™ roof is a brilliant conservatory roof solution!
