9mm Flat Board Soffit

Flat soffit boards finish the underside of the roof overhang. Browse the 9mm boards below and check the required depth, length and joining trims. Plan any ventilation separately to suit your roof construction.

Product details and buying advice

Before you order

Measure the full run and the width of each board, allowing for corners, joints and cuts. Check whether you need a cover board, replacement fascia or soffit: these do different jobs. Follow the product instructions for fixings, support and ventilation.
