We have white cedar shingles on a gable end of our house. The one gable end is exposed to the sun about 4 hours a day. In some areas the shingles have turned a light grey color. Will washing the shingles with the deck cleaner get rid of the grey finish?
We are building an addition on our house and will have western red cedar on the exterior walls. Should we use a sealer on the shingles to keep them looking new throughout the years?
