US RoofVent is the latest, innovative product from DCI Products. With the major success achieved by the SmartVent over the past fifteen years, we wanted to offer the contractor a rolled version, but with all the same great benefits. If you are a roofer that prefers rolled products, here is your solution for intake and exhaust ventilation. US RoofVent helps eliminate mold and moisture issues and is virtually unnoticeable once installed. Twenty feet per roll, it is lightweight, easy to handle and has the same versatility as our industry standard product SmartVent.
