How Roofing Underlayment Protects Your Roof
Roofing underlayment serves as a vital protective layer that safeguards roofs from various forms of damage caused by environmental factors. One of its primary functions is to act as a barrier against water infiltration. When rainwater or melting snow seeps beneath shingles or tiles, it can lead to significant issues such as leaks, mold growth, and structural damage over time.
The underlayment effectively prevents this moisture from reaching the roof deck by channeling it away from vulnerable areas. This protective feature is particularly important in regions with heavy precipitation or fluctuating temperatures that can cause ice dams to form. In addition to moisture protection, roofing underlayment also plays a crucial role in shielding roofs from wind damage.
High winds can lift shingles and tiles, exposing the underlying structure to potential harm. The underlayment helps hold these materials in place, reducing the risk of them being dislodged during storms. Furthermore, it provides an additional layer of insulation that can help regulate temperature fluctuations within the home.
By maintaining a stable indoor environment, roofing underlayment contributes not only to the roof’s longevity but also to the overall energy efficiency of the building.
