Roofing underlayment is an essential component of any roofing system. It serves as a barrier between the roof deck and the shingles, protecting the home from water infiltration and providing an extra layer of insulation. There are two main types of underlayment: synthetic and felt paper. Both have their own unique benefits, but in this blog post, we will be focusing on the importance of synthetic underlayment over felt paper underlayment.
First, synthetic underlayment is made of synthetic material, such as polypropylene or polyethylene. These materials are resistant to water and UV rays, making them more durable and longer-lasting than felt paper. They also have a higher tear resistance, which means they are less likely to be damaged during the installation process.
Synthetic underlayment also offers a higher level of breathability, which allows for proper ventilation of the roof deck. This is important because proper ventilation can help prevent moisture buildup and prevent the growth of mold and mildew.
Another advantage of synthetic underlayment is that it is much lighter than felt paper, which makes it easier to handle and install. This can save time and money on labor costs during the installation process.
One of the biggest advantages of synthetic underlayment is that it is also more fire-resistant than felt paper. This can provide an added level of protection for your home in the event of a fire.
Finally, synthetic underlayment can also be installed in colder weather than felt paper, which can help to speed up the installation process and minimize disruptions to the homeowner.
In conclusion, while both synthetic and felt paper underlayment have their benefits, synthetic underlayment is the clear winner when it comes to durability, breathability, fire resistance, and ease of installation. It is the best choice for homeowners looking for the best long-term protection for their roof.
