Its primary function is to provide an extra layer of protection against moisture intrusion. It prevents water from penetrating the roof deck, which can lead to rot, mold growth, and structural damage. Underlayment also helps to create a smoother surface for the roofing material, improving its appearance and performance. There are different types of underlayment available, including asphalt-saturated felt, rubberized asphalt, and synthetic materials. Synthetic underlayments are generally considered superior due to their higher tear resistance, water resistance, and durability. They are also lighter and easier to install than felt underlayment. The choice of underlayment depends on factors such as the climate, the type of roofing material being used, and the homeowner’s budget. Proper installation of underlayment is crucial to its effectiveness. It should be installed with overlapping seams and secured with roofing nails or staples.
