THE COMPLETE ROOF, CONSIDERED
Roof insulation, considered in context.
Insulation choices form part of the roof build-up and need to suit the existing or proposed construction.
Insulation is one part of the roof system
Where insulation sits and how it connects with other layers can affect the wider roof construction. Existing depth, structure, junctions and how the space is used all matter when considering possible work.
For a new roof, these choices can be discussed alongside the design. For an existing building, the current build-up may need closer investigation before a suitable scope is clear. Photos can start the conversation but cannot confirm concealed layers.
Discuss the complete build-up
Harry can talk through the roof construction, ventilation and the space below, and identify what further information may be needed. See also warm and cold roof systems. This website does not provide a project-specific thermal or building-regulations specification.
A FEW USEFUL ANSWERS BEFORE YOU GET STARTED
Ask Harry.
Have a question about your own roof?
Ask Harry ↗
Can insulation be added without changing the roof?
It depends on the existing construction, available space and the work proposed. The roof should be reviewed as a whole before deciding what can be changed.
Should ventilation be considered too?
Yes. Insulation and ventilation are related to the roof build-up and need to be considered together for the individual project.
