Dormer roof vents made from galvanized aluminum are the most popular choice, but these vents are also made from wood, vinyl, polyurethane, copper and steel. Aluminum roof vents are inexpensive, lightweight and match the lifespan of a standard roof.
Classic homes often have wood dormer vents, but wood vents can rot and are more likely to leak. Even wood dormer vents are fitted with a metal screen to keep out pests.
Construction workers can paint aluminum and wood dormer vents to match the roof or trim. Vinyl and polyurethane options are usually available in several basic colors. Copper dormer vents, which are the most expensive option, are usually not painted.
