Roof Underlayment Installation in Syracuse, NY
When most homeowners think about a new roof, they picture shingles, flashing, and gutters. What many overlook is the critical layer that sits between your roof deck and the visible roofing material. Roof underlayment serves as your home’s hidden shield against moisture, wind-driven rain, and ice damming, all of which are common concerns throughout Central New York. At Blue Collar Roofers, we focus on installing high-performance roof deck protection to prevent moisture infiltration into your home, ensuring that every layer of your roofing system works together for maximum durability and longevity.
As a roofing company partnered with GAF and Owens Corning, we have access to some of the most advanced synthetic underlayment products on the market. This partnership allows us to provide homeowners in Syracuse, NY and surrounding areas with proven moisture control underlayment solutions that far exceed the capabilities of traditional asphalt-saturated felt paper. Every roof we install begins with a proper underlayment strategy tailored to the specific needs of the structure and its environment.
Why Roof Underlayment Matters More Than You Think
Roof deck protection is not optional; it is a code requirement in most jurisdictions and serves as the secondary weather barrier for your home. If shingles are ever compromised by high winds, falling debris, or age-related deterioration, your underlayment is the only thing standing between the elements and your roof deck. Without quality synthetic roofing felt or an equivalent product, water can seep into the plywood sheathing, leading to rot, mold growth, and costly structural repairs.
Traditional organic felt paper has been used for decades, but it comes with significant limitations. It absorbs moisture, wrinkles during installation, and tears easily under foot traffic. Modern synthetic underlayment products offer significantly higher tear resistance—with premium options providing up to 600% more strength than traditional felt—making them the preferred choice among professional roofers today. Synthetic options also resist UV degradation for longer periods, ranging from 30 to 180 days, which is especially important if weather delays occur during construction.
GAF FeltBuster®: The Durable Synthetic Upgrade
GAF FeltBuster® is a durable, non-rotting synthetic upgrade that provides excellent traction for installers compared to typical asphalt felts. It lies flat on the roof deck without the buckling and wrinkling associated with organic felt, making it an ideal entry-level synthetic option for residential roofing projects. FeltBuster is super-lightweight, easy to handle, and delivers reliable moisture protection at a practical performance tier. It meets or exceeds the physical requirements of ASTM D226 Type II and ASTM D4869, ensuring professional-grade quality for every installation.

For homeowners investing in a long-term roofing solution, Tiger Paw delivers unmatched protection on steep-slope applications. Its specialized moisture-control design helps reduce damaging moisture on the roof deck, unlike typical non-breathable synthetic underlayments. Additionally, its UV-stabilized polypropylene construction resists degradation for up to 180 days, providing the ultimate defense for your home.
Our Installation Process and Methodology
Proper installation of roof underlayment is just as important as the product itself. Our roofers begin by inspecting the roof deck for any signs of damage, rot, or inadequate fastening. Damaged sheathing is replaced before any underlayment is applied, as even the best synthetic roofing felt cannot compensate for a compromised structural substrate. We ensure the deck is at least 3/8-inch plywood or 7/16-inch OSB and free of debris or moisture before proceeding.
We install underlayment starting at the eave and working upward toward the ridge, overlapping each course according to manufacturer specifications. This overlap pattern—typically 3 to 4 inches for horizontal laps and 6 inches for vertical laps—ensures that water always flows over the seams rather than under them. In valleys, around penetrations, and along eaves where ice damming is a concern, we pair the underlayment with self-adhered leak barriers for comprehensive protection. For extended exposure, we use specialized plastic cap nails or staples to secure the material and maintain the integrity of the secondary water barrier.
Choosing the Right Underlayment for Your Home
Every residential roofing project in Syracuse presents unique challenges. Roof pitch, ventilation design, local weather patterns, and budget all factor into the decision. As an experienced roofing contractor, Blue Collar Roofers will evaluate your specific situation and recommend the underlayment tier that delivers the best balance of performance and value. Whether you choose GAF FeltBuster for dependable baseline protection, RhinoRoof U20 for added strength, or GAF Tiger Paw for maximum durability, you can trust that your roof deck protection is installed correctly and built to last.
