If the time has come to have your roof replaced, you may have a few decisions to make, such as the color of shingles and whether or not your want vents installed. As part of these decisions, you may be faced with choosing the material of the underlayment, which is the thin material that is placed between the roof deck and shingles.

When it comes to the underlayment, you will probably need to choose between felt and synthetic material. Before you make your decision, consider the advantages of having a synthetic underlayment as opposed to one made of felt.

1.  Synthetic Material Repels Water, Giving Your Roof an Extra Layer of Protection From Moisture

One advantage that synthetic has over felt underlayment is that the synthetic can actually repel water. With felt, if the material is exposed to moisture, it will soak up the water. Since the felt will take a while to dry out, the trapped moisture will stay in contact and cause deterioration of the decking.

However, since synthetic underlayment is virtually waterproof, it adds an extra layer of protection for your roof from moisture. Even if water is able to leak underneath a damaged shingle, the synthetic material can help prevent leaks in your house while you wait to have the damage repaired.

2.  Synthetic Is Stronger Than Felt, Making It More Resistant to Tears and Impact Damage

Another benefit that synthetic has over felt is that it is highly durable. Because of the thin construction of the felt, it can tear easily. If a branch falls on your house and cracks the shingles, there is a good chance that the felt underlayment will be torn.

However, the synthetic material is stronger than felt, allowing it to resist tears and impact damage. Because of its durability, even if the shingles sustain damage, it has a high chance of staying intact and protecting the roof decking.

When it comes time to choose the material for your roof's underlayment, consider that one made from synthetic material is stronger, more durable, and more resistant to water than its felt counterpart. It is often faster to install than felt. Because of the durability of the synthetic material, the roofers do not have to take extra time to keep it from tearing.
