I had a new roof and siding installed in 2011. It is a rear dormered cape. During heavy rain my white vinyl siding develops tiger stripes like what you would see on gutters towards the bottom of the siding and down under windows. I always use a magic eraser to clean it off. This only happens right after heavy rain or after the winter. Is this normal? I have no trees on my property, the house is in the sunlight all day.
