will this unit install with a flat tile roof with the flashing included? Or will it need special flashing and if so WHY?
Thank you for inquiring about the Velux TGR - 014 - 0000. According to the manufacturer specs this unit is designed to be only installed to a flat shingle roof. I am not sure how thick your tiles are on your roof, and cannot advise you if this would work properly for your application. I would recommend calling Velux directly. If you need assistance with any other product questions or placing an order, please contact our customer service dept.
