A roof needs a considered ventilation plan.

Think in connected layers

A roof’s moisture behaviour depends on the construction as a whole. Insulation position, vapour control and ventilation openings need a coordinated design.

Understand the roof you have

A warm-roof build-up and a cold-roof build-up work differently. Identify the existing construction before changing the insulation or adding ventilation.

Choose compatible details

Dry-fix ridge and eaves products should suit the covering and the required ventilation arrangement. Follow current manufacturer guidance and the project specification.

Keep openings working

Routine checks can identify blocked or damaged components. Record any inaccessible areas and arrange suitable access for further inspection where needed.
