What this means for your roof
IKO describes a brown water-soluble residue associated with strong sun, dew and extended dry weather. It distinguishes this early-weathering residue from storage-related oil staining, which may take longer to weather away. The bulletin treats the residue as an appearance issue rather than evidence of reduced roof performance.
A useful question for your contractor
Is this water-soluble residue, oil staining, or a different roof condition?
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
