I recently walked through a Queen Anne home that is for sale and noticed that it has built-in gutters made out of wood that appear to be filled with cement or concrete which is formed in a U shape to carry water to various downspouts. I can't seem to find anything on the internet about this type of gutter system. Is it common to see wood gutters that are lined with cement? Does anyone know of a place on the internet where I can learn more about this style of rain gutter?
