When it comes to roofing, slope matters. For any roof with a pitch below 2/12, traditional shingles aren’t just risky—they’re non-compliant. That’s where CertainTeed’s Flintlastic SA system comes in: a self-adhering, multi-layer membrane designed specifically for low-slope applications.
🧱 What Is Flintlastic SA?
Flintlastic SA is a self-adhered SBS-modified bitumen roofing system that eliminates the need for torches, hot asphalt, or messy adhesives. It’s engineered for residential and light commercial roofs where slope restrictions demand a watertight, layered solution.
- Self-adhering: No flames, fumes, or fasteners
- Multi-ply protection: Base, interply, and cap sheet options
- Code-compliant: Required for pitches under 2/12
- Warranty-backed: Up to 25 years depending on system configuration
🏠 Where and Why It’s Used
| Roof Pitch | Material Allowed | Why Flintlastic SA Is Required |
|---|---|---|
| ≥ 2/12 | Asphalt shingles | Standard slope, water runoff is sufficient |
| < 2/12 | Self-adhered membrane | Shingles can trap water—membranes are required for waterproofing |
Flintlastic SA is ideal for:
- Porch roofs
- Garage additions
- Dormers with low pitch
- Transitional zones between steep and flat sections
🔧 System Components
- Flintlastic SA NailBase – mechanically attached base layer
- Flintlastic SA PlyBase or MidPly – self-adhered interply for added strength
- Flintlastic SA Cap Sheet – self-adhered top layer with granules
- CoolStar® Cap Option – reflective surface for energy efficiency
- Cap FR Option – fire-rated for added protection
🧠 FAQs Homeowners Ask Us
- Why can’t I use shingles on my low-slope roof?
- Shingles rely on gravity to shed water. On low-slope roofs, water can pool—leading to leaks and rot. Membranes like Flintlastic SA are designed to seal and protect these areas.
- Is Flintlastic SA durable?
- Yes. It’s been a trusted solution for over 20 years, with proven bond strength and long-term performance.
- Will it match my shingle roof?
- Absolutely. Flintlastic SA comes in colors that coordinate with CertainTeed shingles for a seamless look.
- Is it safe to install?
- Very. No torches, no fumes, no hot asphalt. It’s ideal for sensitive areas and tight access zones.
💬 What Our Clients Say
“Artisan explained why shingles weren’t right for our porch roof and recommended a self-adhering membrane. The install was clean, and the crew was professional. We’re thrilled with the result.”
“They were honest about what our roof needed and didn’t try to upsell us. The low-slope section was done with a different material, and they explained why. It’s held up beautifully.”
