MasterShield vs. LeafGuard
See which system handles moss, fir needles, and rain more effectively for Seattle homes
Not All Gutter Protection Is Created Equal
If you're considering LeafGuard (or the K Guard knockoff) for your home, here's what you need to know: LeafGuard is a one-piece gutter system with a built-in hood that claims to shed debris. But the reality is, in the Pacific Northwest climate—where moss, fir needles, and heavy rainfall are daily challenges— it doesn't hold up like MasterShield does.
We're not here to trash LeafGuard. We're here to show you where it falls short—and why MasterShield is the smarter, longer-lasting solution for Seattle homeowners.

See how MasterShield outperforms LeafGuard in every category
| Feature | MasterShield | LeafGuard |
|---|---|---|
| System Type | Micro-mesh guard (installs over existing gutters) | One-piece gutter replacement (expensive full replacement) |
| Handles Seattle Debris | ✅ Moss, fir needles, pollen, roof grit | ⚠️ Struggles with fine debris |
| Filtration Technology | ✅ 50-micron surgical steel mesh | ❌ No mesh - relies on hood only |
| Moss Prevention | ✅ Copper-infused kills moss on contact | ❌ No moss prevention built-in |
| Keep Existing Gutters | ✅ Yes - if they're in good shape | ❌ Forces complete gutter replacement |
| Installation Impact | ✅ Minimal disruption | ⚠️ Full system rip-and-replace |
The Problem With LeafGuard
Real issues Seattle homeowners face with hood-style systems
Surface Tension Failure
Hood becomes a shelf for moss, fir needles, and black sludge in Seattle's climate.
Impossible to Clean
Can't clean without disassembling - expensive proprietary system.
Forces Full Replacement
Must replace entire gutter system whether needed or not.
Bottom line: LeafGuard systems rely on surface tension to guide rainwater. In Seattle's real conditions, that hood becomes a shelf for moss and debris. Once buildup starts, water overshoots and your problems return—but now you can't clean it without expensive disassembly.
Why MasterShield Wins
Surgical-Grade Filtration
50-micron mesh blocks even pollen and asphalt grit.
Copper Technology
Kills moss and algae on contact - LeafGuard can't match this.
Roof-Pitch Matched
Installed to your roof angle - debris slides off naturally.
Seattle advantage: Only MasterShield incorporates copper technology that kills moss and algae on contact. Plus, it's installed to match your roof pitch so debris rolls off naturally with gravity and rain, not guesswork.
