If you’re a homeowner in Roanoke, Salem, Vinton, Hollins, Rocky Mount, Bedford, Moneta, Franklin County, or around Smith Mountain Lake, you may have noticed streaks, tiger stripes, or uneven discoloration on your siding, gutters, or painted surfaces. What you’re seeing isn’t just dirt—it’s oxidation, a natural process that slowly eats away at paint and metal, reducing curb appeal and potentially leading to long-term damage.
