Roofing Underlayments
When it comes to roofing, underlayment plays a crucial role in protecting your home from water damage, extending the life of your roof, and ensuring a strong barrier against the elements.
Whether you’re a homeowner or a roofing professional, understanding the different types of roofing underlayments will help you make an informed decision when selecting materials for your roofing project.
What is Roofing Underlayment?
Roofing underlayment is a protective layer installed between the roof deck and the outer roofing material (such as shingles, metal panels, or tiles). Its primary purpose is to provide an additional barrier against moisture, wind, and temperature fluctuations. There are three main types of roofing underlayments: asphalt-saturated felt, synthetic underlayment, and rubberized asphalt underlayment.

1. Asphalt-Saturated Felt
Asphalt-saturated felt, commonly referred to as felt paper or tar paper, has been a traditional choice in roofing for decades. It is made by saturating a base material, such as cellulose or fiberglass, with asphalt to create a water-resistant barrier.
Pros:
- Cost-effective
- Readily available
- Provides a degree of water resistance
Cons:
- Heavier than synthetic underlayment
- Can tear easily under heavy foot traffic or extreme weather
- Absorbs moisture, which can cause wrinkling and reduce effectiveness
There are two common weights of asphalt-saturated felt: 15-pound and 30-pound. The 30-pound felt is thicker and more durable, making it a better choice for enhanced protection.
2. Synthetic Roofing Underlayment
Synthetic underlayment is made from polyethylene or polypropylene polymers, making it lighter, more durable, and more resistant to moisture than traditional felt. It is quickly becoming the preferred choice among roofing professionals.
Pros:
- Lightweight and easy to install
- Highly resistant to tearing and UV exposure
- Offers better water resistance than asphalt felt
- More durable and longer-lasting
Cons:
- More expensive than asphalt-saturated felt
- Some types may be too slick for safe foot traffic
Because of its durability and water-resistant properties, synthetic underlayment is an excellent choice for areas prone to heavy rain and extreme weather conditions.
3. Rubberized Asphalt Underlayment
Rubberized asphalt underlayment is the premium option among roofing underlayments. It consists of a rubber-polymer blend that provides superior waterproofing and self-sealing properties around nails and fasteners. Some varieties come with an adhesive backing for easy installation.
Pros:
- Exceptional waterproofing and sealing capabilities
- Self-adhering varieties simplify installation
- Great for areas prone to heavy rain, ice, or snow
Cons:
- The most expensive option
- Can be challenging to install in hot temperatures
This type of underlayment is ideal for low-slope roofs, valleys, and areas where ice dams or water pooling are concerns.
Choosing the Right Underlayment for Your Roof
Selecting the right roofing underlayment depends on several factors, including climate, budget, roofing material, and installation needs. While asphalt-saturated felt may be sufficient for budget-conscious homeowners, synthetic underlayment offers superior durability and performance. For ultimate waterproofing, rubberized asphalt underlayment is the best option.
A high-quality underlayment can significantly enhance the longevity and effectiveness of your roof. If you’re unsure about which underlayment is right for your home, consulting with a professional roofer will help you make the best decision for your specific needs.
