​How to Choose Between the Materials: Useful Insights

Both synthetic and felt underlayment is used these days. They are popular and manage their functions perfectly. But you should know about the following details before buying one or another piece. First, let’s discuss a synthetic one.

• This one is used more often because it is cheaper. Not every owner or contractor can afford to buy synthetic materials.
• It is resistant to water. You can be sure that rain and snow won’t get through the roof covering.
