What is the difference between 15 pound roofing felt and 30 pound felt?

While #15 is a good option for most roofing jobs, #30 provides more protection and performance for steep roofs and flat roofs. If your roof does not have a steep pitch, you can use #15. This weight of felt is a good economic choice if you have a standard roof.

What roofing felt is best?

We recommend polyester reinforced felt that has been manufactured specifically for heavy-duty use. It is thicker than standard grade shed felt, and like other reinforced products, it has a lifespan of approximately 15 years. The thickness of the product makes it more resistant to tearing when battered by heavy winds.

How much roofing underlayment do I need?

For a new roof, you will also need the same amount of underlayment. So, in the gable roof example above, you would need 240 squares of underlayment. Underlayment usually comes in rolls of 4 squares each. So, covering 240 squares would require 60 rolls of underlayment.
