A well-installed roof underlayment is crucial for protecting your home from the elements. It acts as a secondary barrier against water, wind, and ice, preventing leaks and damage to your roof structure. Synthetic underlayment, in particular, offers superior performance compared to traditional asphalt felt, providing enhanced durability, water resistance, and longevity.
Why Choose Synthetic Roof Underlayment?
Synthetic underlayment, often made from materials like rubberized asphalt or polymer-modified bitumen, boasts several advantages over traditional felt:
Benefits of Synthetic Underlayment:
- Superior Water Resistance: Synthetic materials excel at repelling water, offering better protection against leaks.
- Increased Durability: They are more resistant to tearing, punctures, and UV degradation, extending their lifespan.
- Improved Wind Resistance: Synthetic underlayment adheres tightly to the roof deck, reducing the risk of wind uplift.
- Lightweight and Easy Installation: Their lighter weight makes them easier to handle and install compared to heavy felt.

How To Install Synthetic Roof Underlayment
Synthetic roof underlayment is a crucial component of a durable and weather-resistant roof system. It acts as a secondary barrier against water infiltration, protecting your home’s structure from damage. Installing synthetic underlayment correctly is essential for its effectiveness. This guide will walk you through the process step-by-step, ensuring a successful installation.
Tools and Materials
Before you begin, gather the necessary tools and materials:
- Synthetic roof underlayment
- Roofing nails
- Hammer or nail gun
- Utility knife
- Tape measure
- Scissors or shears
- Safety glasses
- Work gloves
Preparation
Inspect the Roof Deck
Begin by thoroughly inspecting the roof deck for any damage, such as rot, cracks, or loose boards. Repair any issues before proceeding with the underlayment installation. A sound roof deck is essential for a successful installation.
Clean the Roof Deck
Remove any debris, such as leaves, twigs, or loose shingles, from the roof deck. A clean surface ensures proper adhesion of the underlayment.
Installing the Underlayment
Starting Point
Choose a starting point on the roof, typically near the eaves. Unroll the first piece of underlayment, ensuring it overlaps the starter shingles by at least 6 inches.
Laying the Underlayment
Continue laying the underlayment in horizontal strips, overlapping each strip by at least 6 inches. Use a utility knife to trim the underlayment to fit around vents, chimneys, and other roof penetrations.
Securing the Underlayment
Secure the underlayment to the roof deck using roofing nails spaced every 12 inches along the edges and every 24 inches in the field. Drive the nails through the underlayment and into the roof deck, ensuring they are flush with the surface.
Flashing Around Penetrations
Flashing is crucial around roof penetrations to prevent water from entering the home. Use self-adhesive flashing tape to seal the underlayment around vents, chimneys, and other penetrations.
Final Touches
Inspect the entire underlayment installation for any gaps or tears. Repair any issues immediately. Once the underlayment is properly installed, you are ready to proceed with the shingle installation.
Installing synthetic roof underlayment is a crucial step in ensuring your roof’s longevity and protection. By following the steps outlined in this article, you can confidently tackle this project and safeguard your home from the elements. We’ve covered everything from choosing the right underlayment for your needs to understanding proper installation techniques, including nailing patterns, overlapping, and flashing.
