What is Roof Underlayment?
Roof underlayment is a protective layer installed between the roof deck and the primary roofing material. It serves as a crucial component of a well-designed roofing system, offering essential functions that contribute to the performance and longevity of your roof.
Functions of Roof Underlayment
Water Protection
Roof underlayment acts as a secondary barrier, creating an extra layer of defense that catches any water that penetrates the shingles. This helps prevent leaks and water damage to your roof deck and the interior of your home.
Moisture Management
Moisture can build up underneath your roof due to condensation, rain, or snow. Roof underlayment, especially breathable underlayment types, allows proper ventilation by creating an air gap between the shingles and the roof deck. This helps moisture escape, preventing problems like rot or mold growth.
Thermal Insulation
Roof underlayment can add another layer of insulation to your roof system, depending on the material. This can help improve your home’s energy efficiency by keeping it cooler in the summer and warmer in the winter. Better efficiency translates to lower energy bills and increased comfort throughout the year.
Types of Roof Underlayment
Asphalt-Saturated Felt
Asphalt felt is the most budget-friendly option for underlayment. It’s also lightweight and familiar, and felt is relatively simple to install. On the downside, felt underlayment has a shorter lifespan compared to other options, typically lasting 10 to 15 years. Felt can also absorb moisture over time, reducing its effectiveness and potentially leading to rot.
Synthetic Underlayment
Made from advanced materials like polypropylene, synthetic underlayment offers superior strength and a longer lifespan (20 to 50 years). Synthetic underlayment also excels at repelling water, providing enhanced protection against leaks. On the downside, synthetic underlayment comes at a higher price point compared to felt.
Rubberized Asphalt Underlayment
Rubberized asphalt underlayment features a rubberized asphalt layer that automatically seals around fasteners, creating a watertight barrier. Similar to synthetic underlayment, it also offers excellent protection against water infiltration. On the downside, rubberized asphalt underlayment is the most expensive option on this list.
Factors to Consider When Choosing Underlayment
Climate and Weather Conditions
- Hot and Humid Climates: Prioritize breathability to prevent moisture buildup. Synthetic underlayment might be a good choice.
- Cold and Snowy Climates: Focus on water resistance and durability. Rubberized asphalt underlayment could be ideal.
- High Wind Areas: Durability and tear resistance are key. Synthetic underlayment or a reinforced felt option might be suitable.
- Roof Pitch and Slope: Steeper roofs require a higher level of water resistance. Rubberized asphalt underlayment or certain synthetic underlayments excel here.
- Type of Roofing Material: Different roof materials, like metal or slate, may have specific underlayment compatibility requirements.
