Roofing felt is one of the most important yet often overlooked components in a roofing system. For homeowners in Queens, New York, where weather conditions shift between heavy rain, snow, humidity, and strong winds, protecting the roof becomes a long-term investment rather than a short-term fix.
This is where roofing felt plays a critical role. It acts as a protective barrier between the roof deck and the outer roofing material, helping to prevent moisture intrusion, structural damage, and early roof failure. Whether you are planning a new installation or upgrading an existing system, understanding roofing felt is essential for improving durability and performance.
In this guide, you will learn what roofing felt is, its purpose, types, roof installation methods, and why it is still widely used in modern roofing systems. You will also understand how it compares with newer materials and why professional installation matters for homes in Queens.
What is Roofing Felt and Why It Matters
Understanding roofing felt in simple terms
Roofing felt, also known as roofing felt paper, is a protective underlayment layer installed beneath shingles roof or other roofing materials. It is commonly made using bitumen or synthetic compounds and is designed to provide a moisture resistant barrier.
In roofing systems, it is also referred to as felt paper for roofing or felt roof underlayment, depending on the material type and usage.
Roofing felt purpose in modern roofing systems
The main roofing felt purpose is protection. It prevents water from penetrating the roof deck and acts as a secondary shield in case the outer roofing layer fails.
Key functions include:
- Moisture barrier protection
- Temporary weather resistance during installation
- Added insulation layer
- Protection against wind driven rain
This layer becomes especially important in flat roofing systems commonly found in Queens homes.
Types of Roofing Felt Used in Roofing Systems
Traditional and modern felt materials
There are several types of roofing felt used in residential and commercial roofing today.
Common options include:
- Organic felt made from cellulose fibers
- Fiberglass reinforced felt for durability
- Modified bitumen felt for high performance roofing
- Synthetic roof felt, which is lightweight and highly durable
Each type serves different roofing needs depending on climate and roof structure.
Roofing Felt vs Tar Paper
When comparing roofing felt vs tar paper, it is important to understand that both materials serve as underlayment in roofing systems, but they differ in composition, durability, and modern usage. Homeowners in Queens often encounter both terms during roof repairs or replacements, especially in older homes.
Tar paper is an older roofing material, while roofing felt is its improved and more durable successor.

| Flexibility | More flexible | Less flexible, becomes brittle over time |
| Water Resistance | Good moisture protection | Basic water resistance |
| Weather Performance | Performs better in harsh climates | Weak against extreme weather |
| Lifespan | Longer (10–20 years approx.) | Shorter (5–10 years approx.) |
| Installation Ease | Easier and cleaner installation | Heavier and harder to handle |
