The answer to 'underlayment damage' is that underlayment damage is a common issue that can occur in roofing systems. Underlayment is the protective layer installed between the roof deck and the shingles or other roofing material. It helps prevent water infiltration and provides an additional layer of protection. Common causes of underlayment damage include improper installation, age and weathering, and damage from roof leaks or other external factors.
Symptoms of underlayment damage can include visible cracks, holes, or deterioration in the underlayment, as well as water stains or leaks in the attic or interior spaces. In some cases, the damage may not be immediately visible, but can lead to more serious issues like mold, rot, or structural damage if left unaddressed.
