The answer to 'why is my fascia' is that the fascia board, which is the horizontal board that runs along the roof's edge, can become damaged or deteriorated for several reasons. Common causes include water damage, sun exposure, and improper installation. Symptoms may include cracks, warping, or rotting of the fascia board.
If the fascia is in poor condition, it can lead to further roof and gutter issues. Addressing the problem early is important to prevent more extensive and costly repairs down the line. In many cases, the fascia can be repaired or replaced by a DIY homeowner. However, for significant damage or if you're not comfortable with the work, it's best to hire a professional roofing contractor to assess the situation and provide the necessary repairs.
