Explanation:
Darkened or blackened wood shingles are an indication of fungal growth and decay. Fungi, such as mold or mildew, can thrive in damp and shaded areas, leading to the discoloration of wood shingles. This can weaken the structural integrity of the shingles and may require treatment or replacement. Prevention can be achieved by ensuring good ventilation, minimizing areas of constant shade, and using mold-resistant shingles or treatments. If the darkening is happening on your roof, it's important to get it checked as it may affect the longevity of your roof.
