Roof ventilation isn't optional in a well-built roof. A sealed roof space with no airflow gets damp, hot, and mouldy - and shortens the life of insulation and timber. ADCO plans ventilation alongside the roof profile, insulation, and flashings.

Ventilation and roof performance

Roof ventilation decisions can affect moisture, heat, roof-space comfort, and how the roof system performs over time.

Planning with insulation

Insulation and ventilation should be considered together so the roof space is not simply sealed without a practical plan for moisture and airflow.

New roof and re-roof timing

Ventilation systems are often easier to discuss during new roof planning, re-roofing, or repair work because access and roof penetrations are already being considered.

Weather-tight installation details

Any roof ventilation product needs careful detailing around penetrations, flashings, fixings, and roof profile so it does not create a new leak risk.

Roof Ventilation FAQs

Can ventilation be added during a roof replacement?

Yes. Replacement planning can be a practical time to discuss roof-space airflow, product placement, and weather-tight detailing.

Does roof ventilation create leak risk?

Any penetration can create risk if detailed poorly, which is why ventilation should be planned with the roof profile, flashings, and installation method.
