The best roofing felt for sheds is asphalt felt, also known as tar paper. This material is affordable, easy to install, and works well for small structures. Asphalt felt comes in different grades and weights. Most homeowners pick it because it costs less than other options. According to industry data, asphalt shingles account for nearly 80% of residential roofing projects in the U.S., and felt underlayment pairs perfectly with these systems.

What Types of Roofing Felt Exist?

There are three main types of roofing felt. Traditional asphalt felt is the most common. It costs between $0.50 and $1.50 per square foot. Synthetic felt is newer and lasts longer, but costs more. Fiberglass felt is another option that sits in the middle for price and durability.

Each type has pros and cons. Asphalt felt tears easily but is cheap. Synthetic felt resists tears and lasts 30+ years, similar to architectural asphalt shingles which last about 30 years according to roofing data. Fiberglass felt balances cost and strength well.

Why Does Felt Matter for Sheds?

Roofing felt protects your shed from water damage. It sits under shingles and catches leaks. Without it, water soaks into wood and causes rot.

Felt also helps shingles stick better to the roof. According to roofing installation data, proper underlayment preparation is critical for durability. Good felt prevents shingles from curling up in hot weather. It keeps your shed dry for 20 to 30 years, matching the lifespan of basic asphalt shingles.

How to Pick the Right Felt for Your Shed

First, measure your shed roof in squares. One square equals 100 square feet. Most sheds use one to three squares. Then check the weather in your area. Hot, dry climates need reflective or light-colored options. Wet, rainy areas need thicker, more durable felt.

Installation Tips for Shed Felt

Start at the bottom of your roof. Overlap each row by six inches. Use roofing nails or staples to secure it. According to roofing data, proper installation techniques prevent wind damage and leaks. Leave a slight gap at the ridge for air flow.

Do not stretch the felt too tight. This causes wrinkles and premature wear. A well-installed felt layer protects your shed investment for decades. According to the National Association of Home Builders, average roof sizes are measured in squares, and proper underlayment is essential for all structures, large and small.
