Our soffits protect the hard-to-paint areas of your roof rafters by showing mold and mildew the door. They increase ventilation to your attic, which comes in handy if you do more than store old clothes up there. And there's no denying their lofty design power: Our soffits help tie together the whole look of your home exterior. Don't overlook any of our soffit varieties. Use with 3/4" Frieze Trim and 3/4" T-Trim.
