Polystick XFR Underlayment Review: Is It Worth It for Florida Roofs?
When it comes to roofing in Florida, choosing the right underlayment is just as important as choosing the roofing material itself.
One of the most popular options among contractors is Polystick XFR underlayment. But is it the right choice for your roof in Boca Raton or Palm Beach County?
In this review, we break down what Polystick XFR is, its benefits, and whether it's worth using on your next roofing project.
What Is Polystick XFR Underlayment?
Polystick XFR is a self-adhered roofing underlayment designed for use under tile, metal, and shingle roofing systems.
It is widely used in South Florida because it meets strict building code requirements and provides strong protection against water intrusion.
Polystick XFR also carries both Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval, meaning it has been tested and approved for use in high-wind and hurricane-prone regions.
Key Benefits of Polystick XFR
1. Self-Adhered System
Polystick XFR sticks directly to the roof deck, creating a tight seal that helps prevent water from getting underneath the roofing system.
This is especially important in Florida, where heavy rain and wind-driven water are common.
2. Strong Water Protection
This underlayment acts as a secondary water barrier, which is critical during storms and hurricanes.
In many cases, using a self-adhered underlayment like Polystick XFR can help qualify homeowners for insurance discounts for having a secondary water barrier, depending on the insurance provider.
3. NOA Approved & Florida Product Approved
Polystick XFR meets both Miami-Dade NOA requirements and Florida Product Approval standards, which are some of the strictest roofing requirements in the country.
This means:
- It is approved for high-velocity hurricane zones (HVHZ)
- It meets Florida Building Code requirements
- It is trusted by contractors across South Florida
4. Durable and Tear Resistant
Polystick XFR is built to handle tough job site conditions and provides long-lasting protection under your roof system.
5. Works Well with Metal Roofing
For metal roofs, especially standing seam systems, having a high-quality underlayment is essential.
Polystick XFR provides a smooth, secure surface that improves the overall performance of the roof.
Are There Any Downsides?
While Polystick XFR is a great product, there are a few things to consider:
- Higher cost compared to traditional felt underlayment
- Requires proper installation for best performance
- Surface must be clean and dry before application
Is Polystick XFR Worth It in Florida?
For homeowners in Boca Raton and Palm Beach County, Polystick XFR is often worth the investment.
Because of Florida's weather conditions, having a strong secondary water barrier can make a big difference in protecting your home.
Additionally, the potential for insurance discounts makes it even more valuable over time.
Many professional roofing contractors prefer this system for long-term durability and performance.
Professional Installation Matters
Even the best underlayment won't perform properly if it's not installed correctly.
Proper installation ensures:
- Full adhesion to the deck
- No wrinkles or gaps
- Proper sealing around penetrations
The contractor's experience installing self-adhered underlayments like Polystick XFR can also affect how clean and smooth the final roofing system looks, especially under metal roofs.
