The Ariel Coroline Black Roofing Ridge is a preformed bitumen ridge cap designed to provide a neat, weather-resistant finish along the apex of pitched roofs fitted with Coroline corrugated roofing sheets. Manufactured from the same material as Coroline roofing sheets, this lightweight and flexible ridge piece can be adjusted to accommodate varying roof angles. Preformed end lap grooves help simplify installation and ensure consistent overlaps between adjoining ridge sections. Ideal for roofing projects involving sheds, garages, workshops, summerhouses and other suitable outbuildings.
