THE COMPLETE ROOF, CONSIDERED
Roof ventilation, part of the whole.
Ventilation should be considered with the roof construction and insulation, not as an isolated detail.
Understand the roof before changing airflow
Roof ventilation arrangements depend on the construction, insulation position and project details. Changes to one part can affect how the complete build-up works, so the existing arrangement and the reason for the enquiry should be understood first.
If you have noticed condensation, damp or deterioration, describe where and when it appears. These symptoms can have different causes and cannot be diagnosed from a short description alone.
Consider ventilation with insulation
Harry can discuss ventilation alongside roof insulation or warm and cold roof systems. Share drawings or details if available; a project-specific assessment is needed before deciding on an arrangement.
A FEW USEFUL ANSWERS BEFORE YOU GET STARTED
Ask Harry.
Have a question about your own roof?

Can I add vents to an existing roof?
The appropriate approach depends on the roof construction and the issue being addressed. Have the roof assessed before altering it; a vent added in isolation may not suit the whole build-up.
Does insulation affect roof ventilation?
It can. The two need to be considered together with the structure and other layers in the roof.
