What should be installed behind a new roofline?
The finished fascia and soffits are only part of the installation.
On this property in Cardiff, we removed the old roofline and installed a complete new white uPVC fascia and soffit system with black guttering.
As part of the installation, you’ll see two important components that are hidden once the job is complete:
✔ Eaves protection trays to support the roof felt and help direct rainwater into the gutter.
✔ Over fascia ventilation to allow air to enter the roof space, helping to reduce condensation and maintain healthy roof ventilation.
These are the details many homeowners never see, but they’re an important part of a professionally installed roofline that’s designed to perform for years to come.
