Synthetic Roofing Underlayment:
Pros:

1. Durability: Synthetic underlayment is known for its high durability. It can withstand exposure to the elements, including UV rays, without deteriorating quickly. This makes it an excellent choice for areas with extreme weather conditions.
2. Lightweight: Synthetic underlayment is generally lighter than felt, making it easier to handle during installation. The reduced weight can also contribute to overall weight savings on the roof structure.
3. Water Resistance: Synthetic materials are inherently resistant to water, providing an effective barrier against moisture. This helps prevent water infiltration and protects the roof deck and other structural components.
4. Installation Efficiency: Due to its lightweight and flexibility, synthetic underlayment is often easier and faster to install compared to felt. This can potentially save on labor costs and reduce installation time.

Cons:

1. Cost: Synthetic underlayment tends to be more expensive upfront than felt. While it offers long-term durability, the initial cost may be a consideration for some homeowners.
2. Environmental Impact: Some synthetic materials may have environmental implications. It's essential to choose products that prioritize sustainability and eco-friendly practices.

Felt Roofing Underlayment:
Pros:

1. Cost-Effective: Felt underlayment is generally more budget-friendly compared to synthetic alternatives. This can make it an attractive option for homeowners looking to save on roofing costs.
2. Tradition and Familiarity: Felt has been a staple in roofing for many years, and many roofing professionals are familiar with its installation and properties. This can contribute to a smoother and more straightforward installation process.
3. Breathability: Felt underlayment is breathable, allowing for moisture vapor to escape from the roof structure. This can be advantageous in preventing issues related to condensation and trapped moisture.

Cons:

1. Durability: Felt is not as durable as synthetic materials, especially in extreme weather conditions. It may be prone to tearing or damage during installation or exposure to severe weather.
2. Weight: Felt tends to be heavier than synthetic alternatives. While this may not be a significant concern in many cases, it's something to consider, especially for structures with weight restrictions.
3. Water Absorption: Unlike synthetic underlayment, felt can absorb water. While it still provides a certain level of protection, prolonged exposure to moisture can affect its performance over time.
