Introduction
Many conservatories are now reaching the end of their natural life or are costing substantially more to heat than previously. Homeowners are looking for a cost effective way of retaining existing floor space whilst improving the energy efficiency of the structure. To meet this need homeowners are choosing to replace obsolete translucent roofs with solid ones.
This guidance has been produced to advise and inform suppliers, builders, architects and design consultants on the Building Regulations that will apply to the replacement of a translucent roof to a conservatory or porch with a solid roof.
The preferred option for many homeowners is a lightweight composite solid roof. Some roofs have a LABC Registered Detail that provides an approved design, quality control and accredited installation. Other options may simply underdraw or overclad existing polycarbonate roofs. Or replace the existing roof with a traditional tiled roof that may not have taken into account the adequacy of the existing structure
to carry increased loading.
