What effect does asphalt bleeding have on a roofing surface?

Asphalt bleeding occurs when the asphalt in a built-up roofing system seeps to the surface, creating a glossy appearance. This phenomenon typically leads to discoloration of the roofing material, which can be unsightly and diminish the aesthetic appeal of the roof. The presence of this bleed-through may indicate that the roofing membrane is experiencing excessive heat, which can cause the asphalt to become overly fluid and permeate the surface layer.

While some might consider the potential benefits of adhesion and waterproofing in roofing materials, in this case, the primary concern with asphalt bleeding is indeed its impact on the appearance through discoloration. Understanding this helps in assessing the condition of a roofing system and determining if any corrective actions or maintenance are necessary to ensure long-term performance.
