Our bitumous felt roof shingles, otherwise known as felt shingles typically have a life span of around 7-10 years. They are available in green, brown or black or red. They are easy to apply and can be used on cabin roofs with a slope of 10 degrees or more if fitted with a breathable membrane. Due to the method of overlapping the cabin roof gets a double layer of shingle protection. These are standard on our log cabins (except Moderna style).
