The answer to 'underlayment worn out' is that a worn-out roof underlayment is a common problem that can lead to leaks, water damage, and even structural issues if not addressed. Underlayment is the protective layer installed between the roof sheathing and the outer roofing material, and it plays a crucial role in keeping your home dry and protected.
Common causes of worn-out underlayment include age, exposure to the elements, poor installation, or damage from previous roof work. Symptoms may include visible wear, cracks, or holes in the underlayment, as well as signs of leaks or water damage in the attic or interior of the home.
