SnoJax I Polycarbonate Snow Guard

Q: Can I re-use or relocate SnoJax I guards later?

Yes. Unscrew the fasteners, remove the guard, and re-install elsewhere on the roof or on a new roof. The polycarbonate doesn't degrade from fastener holes, and the guard remains fully functional.

The Standard-Bearer for Mechanical Roof Attachment

SnoJax I set the benchmark for screw-down polycarbonate snow guards when it hit the market. After decades of field performance, it remains the go-to choice for contractors who want a zero-ambiguity mounting method: two pre-drilled holes, fasteners from below, done.

Manufactured from 100% virgin UV-stabilized polycarbonate—not recycled—ensuring clarity and durability that lasts 30+ years in harsh snow climates. The material is roughly 30 times stronger than acrylic, resistant to impact, and won't yellow or cloud over time.

Two pre-drilled fastener points positioned near the face for clean, direct mounting
Works with standing seam, R-panel, and mechanically fastened metal roofs—no special adapters needed
Pairs with #14 Master Gripper or #14 Master Driller screws depending on purlin material (wood or metal)
Apply NovaFlex MR-150 sealant under fastener heads to block water infiltration

Why Mechanical Fastening?

No adhesive means no seasonal expansion/contraction stress. Two screws lock the guard in place permanently. Contractors love it because installation is straightforward, field-testable, and requires no curing time.

Fast Install

Drill, screw, seal — production roof in hours

Field Testable

Walk the line post-install to verify hold-down

No Cure Time

Operational the moment the last screw tightens

What Makes SnoJax I the Right Choice

Optically Clear

Virtually invisible from ground level—maintains your roof's aesthetic.

100% virgin polycarbonate resists yellowing and discoloration. The material remains optically clear for three decades, even under intense UV exposure in alpine or sub-arctic regions.

Proven Durability

Withstands thermal cycling, hail, and sustained snow loads.

The original SnoBlox-Snojax formula has protected roofs since the 1970s. Field data confirms zero brittleness, zero crazing, zero failure under normal maintenance protocols.

Two-Point Security

Redundant fastening prevents rocking or vibration under wind.

Pre-drilled holes are positioned to distribute load across the guard face. Even on exposed ridgelines, the mounting holds rock-solid—no migration, no micro-movements.

SnoJax I vs. Adhesive-Mount Guards

Aspect	SnoJax I (Screw-Down)	Adhesive-Mount Guards
Installation Speed	30–45 minutes per roof section	2–3 hours (including surface prep, adhesive cure)
Thermal Stress	Minimal — mechanical fastening decouples movement	High — adhesive bears all stress from metal panel expansion
Weather Dependency	Install anytime — no temperature limits	Air temp must be 40°F+ for adhesive bonding
Field Inspection	Visual check confirms fastener integrity	Adhesive bond hidden — can't verify hold-down post-install
Longevity	40+ years with mechanical fastening unchanged	Adhesive degrades over time; 20–30 year window typical
Retrofit / Relocation	Guards can be removed and reinstalled	Adhesive separation may damage the panel

Common Roof Applications

Standing Seam Metal

SnoJax I mounts directly to standing seam ribs. Use Master Gripper or Driller depending on purlin material. No special adapters required.

R-Panel & Corrugated

For R-panel and corrugated metal, position guards in valleys or on ribs. Two fasteners per guard anchor it securely against wind vibration.

Mechanically Fastened

Existing fastening patterns on mechanically fastened metal roofing provide natural anchor points. Install SnoJax I guides per the application notes.

Frequently Asked Questions

Will two fasteners hold the guard under a heavy snow load?

Yes. SnoJax I guards are engineered to resist snow loads well beyond typical North American climates. The two pre-drilled fastener points distribute load across the guard face and into the metal substrate. Field data from alpine regions (Colorado, Alberta, British Columbia) confirms zero movement under sustained loads over 30+ years. The fasteners must be tightened snug but not over-torqued; use a hand or cordless drill set to moderate torque to avoid cracking the guard.

Can I install SnoJax I in winter or cold weather?

Absolutely. One of the key advantages of mechanical fastening is that you're not waiting for adhesive to cure or worrying about temperature-dependent bonding. Drill, screw, seal, and you're done—even in sub-zero conditions. The polycarbonate itself remains pliable down to –40°F, so cold-weather installation is routine.

What sealant goes under the fastener heads?

Use NovaFlex MR-150 sealant under each fastener head. Apply a small bead around the screw hole, thread the fastener through the guard, and into the purlin. As the screw tightens, it compresses the sealant into a weathertight plug. This blocks wind-driven water infiltration at the penetration point—critical for long-term guard performance.

How do I know which fastener to use—Master Gripper or Master Driller?

Master Gripper screws are designed for wood purlins; Master Driller screws are for metal purlins. Before you order, identify the purlin material on the roof (inspect under a raised panel or ask the roofing contractor). If unsure, call us at 437-475-2066 and describe your roof structure—we'll confirm the right fastener in 30 seconds. Both fasteners are compatible with SnoJax I pre-drilled holes.

Can I re-use or relocate SnoJax I guards later?

Yes—one of the lasting benefits of mechanical fastening. Unscrew the fasteners, remove the guard, and re-install elsewhere on the roof or on a new roof. The polycarbonate itself doesn't degrade from fastener holes, and the guard remains fully functional. This flexibility is impossible with adhesive-mounted guards, which can't be separated without damaging the substrate.
