While NFRC is a dedicated roofing trade association that has been around for over 120 years we have never recognised the practice of moss removal or roof painting as a true roofing discipline. The reason being, in most instances, moss on roof tiles is rarely a problem and only needs to be removed if it is blocking gutters, outlets and other drainage points on the roof. Most ‘techniques’ that we have come across to remove moss, are often achieved by ‘violent’ means such as power-washing, which may cause damage to the roof, especially when combined with unnecessary foot traffic often leading to cracked or broken roof tiles.
