A roll of roofing felt costs between $50 and $150, depending on the type and size you buy. Roofing felt is a layer that goes under your shingles to protect your roof from water and weather. Most homeowners need this material when they replace their roof or repair damage. The price changes based on the quality of the felt and how much area it covers. Understanding the cost helps you budget for your roofing project.
What Types of Roofing Felt Exist?
Roofing felt comes in two main types: asphalt felt and synthetic felt. Asphalt felt is the cheaper option and costs less per roll. Synthetic felt lasts longer and resists damage better than asphalt felt.
Most rolls cover about 400 square feet. A standard roll of asphalt felt runs $50 to $80. Synthetic felt rolls cost $100 to $150 because they are stronger and last longer.

How Much Felt Do You Need?
The amount of roofing felt you need depends on your roof size. According to industry data, the average U.S. roof size is 2,647 square feet or 26.47 squares. Each square equals 100 square feet.
For a typical home with a 1,700 square foot roof, you would need about 4 to 5 rolls of felt. Larger roofs need more rolls. Always order extra rolls because waste happens during installation.
What Affects the Price?
Several things change the price of roofing felt. Brand name matters. Well-known brands cost more than generic brands. Quality also plays a role. Better felt resists weather longer.
Labor and installation costs add to your total roofing expense. According to RubyHome (2025), roof installation costs range from $4 to $40 per square foot. For a 1,700 square foot roof, that means $6,800 to $68,000 total. Felt is just one small part of this cost. According to industry data, asphalt roofing material costs $4.25 to $4.95 per square foot when installed.
| Felt Type | Price Per Roll | Coverage Per Roll |
|---|---|---|
| Asphalt Felt | $50, $80 | 400 sq. ft. |
| Synthetic Felt | $100, $150 | 400 sq. ft. |
Should You Buy Quality Felt?
Investing in better felt saves money over time. Synthetic felt lasts longer and protects your roof better. According to RubyHome (2025), architectural asphalt shingles cost $4.50 to $8.25 per square foot and last 30 years. Quality underlayment like felt helps your shingles last their full lifespan.
Cheap felt can tear during installation or fail early. This leads to leaks and expensive repairs. According to the Insurance Information Institute (2024), leaking is the reason 33% of homeowners replace their roofs. Good felt prevents this problem. Spending a little more now means fewer problems later.
