Roofs can be an important architectural feature

Roofs can define the architectural characteristics of the built form.  They can express entrances and/or put a unique twist to the building that they are covering.

Roofs need to be designed and constructed to accept snow and wind loads.  They need to be insulated and often form part of the thermal and heat loss calculations required by the Building Regulations.

The materials that are used to cover the roofs are very much dependent on the pitch. Clay tiles are not recommended for pitches below 35 degrees, whereas composite and concrete tiles can be laid at minimum pitches of 15 to 18 degrees.  Membrane sheeting is normally used for flat roofs.  Metal and composite sheeting can generally be laid to all pitches to a minimum of 5 degrees, subject to manufacturer’s recommendations.  

The roofs connection details are extremely important, as clients do not want the roofs to leak. Metal flashings, soakers and edge upstands need to be designed and built well.

As architectural statements, roofs can be designed to have porticos, over-hanging eaves, sweeping forms and other dramatic features.  Some notable architects are recognised for their roofs and the statements they make (i.e: Zaha Hadid ).
