Roof Soffit Types

Open Eaves

• Open eaves are designed with open beams and rafters. These are not actually true soffits, but the exposed wood takes the place of soffit material and performs the same task. This type of soffit design can be painted the same color as siding, but may not be made out of siding material. In these cases, a new layer of soffit siding may be installed if the open eaves become damaged or need a style change.

Closed Eaves

• Closed eaves are a type of eave construction more common in newer houses in which the rafters and beams are fully covered by the soffit material. This type of paneling is made from the same material as the siding, which helps protect the underside of the rooftop more completely than the open eave system. This type of soffit is installed as paneling nailed and caulked over the roof beams on the overhang.

Materials

• Soffits should usually match the siding and materials used on the rest of a house, so there are several types of soffits distinguished by what they are made from. Vinyl soffits are made from plastic and provide notable moisture protection. Metal soffits are designed for aluminum siding or other types of metal walls. Wood soffits are used to match wood siding.

Ventilated

• Some soffits are ventilated, or installed with certain panels that have holes or slits for air to pass through. This is a necessary solution when attic vents open into the underside of rooftops and are covered up by soffits. The ventilation gives air access to the attic area and prevents moisture and heat problems.
