Most owners figure those dark streaks are dirt off the trees, and that a good rain will rinse them. I've cleaned enough roofs to tell you it works the other way. The streaks are a living algae, and it feeds on the limestone filler inside your asphalt shingles. Rain keeps it wet, and the deep oak shade keeps the shingles from drying out. That's why the tree side of a roof around here streaks first and worst. On the older brick ranches near Forest Lake, a roof can stay damp well into the afternoon. The fix is a kill, a soft wash that stops the growth where it starts.
Forest Acres is named for its trees, and the name is honest. It grew up as a wooded suburb east of downtown Columbia, and today its brick ranches and split-levels from the 1950s and 60s sit under one of the oldest, heaviest hardwood canopies in the Midlands. Gills Creek runs through the middle of town, and Forest Lake, the old mill pond dammed where the creek was first put to work, anchors the Forest Lake Country Club and the established streets around Rockbridge Road. Between the deep oak shade, the creek, and the small lakes, whole blocks around North Trenholm and Satchel Ford stay cool and damp for most of the day, and the mature azaleas and camellias that fill these yards are exactly the kind of landscaping owners here want protected. Trenholm Plaza is the everyday retail heart of town.
