3 Top Factors in Choosing Roof Underlayments

Whether you’re installing new synthetic roofing or maintaining an older asphalt-shingle roof, synthetic underlayments are an ideal option for several reasons. One big benefit is that synthetic underlayments are waterproof and can help prevent moisture from getting into your home.

Synthetic underlayments also protect against ice dams during winter months and ensure protection against hail damage as well.

Common Uses of Synthetic Roofing Underlayments

Some roof underlayments are waterproof, but many are not. Synthetic roofing underlayments are a good option for waterproof protection as long as the seams are properly sealed and flashing is installed where necessary. Tiles often require more flashings than shingles. Some synthetic underlayments can be peeled off easily, while others require heavy machinery to remove them once they’re on your roof.

There’s also an increased risk of tearing asphalt or tar paper when installing these materials due to their thinness. Finally, synthetic roofing underlayments usually have a shorter lifespan and will need replacing sooner than other types of materials like felt paper or tar paper. But if you want watertight protection that doesn’t need re-coating, then this type of material may be right for you.


Unfortunately, this is not a question we can answer with a simple yes or no. Synthetic roofing underlayments are not made of wood, so they do not breathe like wood. However, synthetic roof underlayments are designed to be waterproof and the granules can act as insulation on the roof.
