Rainwater Harvesting
Harvest the Rain. Protect the Planet.
Sustainable Water Starts at the Roofline—with MasterShield®
Rain isn’t a nuisance. It’s a resource.
In Seattle, we’re surrounded by one of the most renewable elements on Earth—water. Rain falls on our roofs nearly year-round, yet most of it ends up in storm drains, wasted.
Rainwater harvesting flips that script. By capturing rain off your roof and storing it in a cistern or catchment system, you can:
Reduce strain on public water systems
Lower your environmental footprint
And take a meaningful step toward self-reliance and sustainability
But to keep your system eco-friendly, you need to keep it clean from the start. That’s where MasterShield® comes in.
Clean Water In = Cleaner Planet Later
Your gutters are your first filtration point. If they’re full of roof grit, pollen sludge, or mossy runoff, that contamination flows straight into your storage system—polluting your water and shortening the life of your filters, pumps, and tank.
MasterShield solves this at the source.
🌿 Ultra-Fine Filtration
Its surgical-grade stainless steel mesh captures particles down to 50 microns, far finer than traditional screens or grates.
🌿 Natural Moss & Algae Control
Woven copper thread actively inhibits moss, algae, and mildew growth—no chemicals, no power, just passive protection.
🌿 Pitched with Your Roof
Installed at the same angle as your shingles, MasterShield sheds debris with rainwater flow—keeping organics out of your system before they can break down.
Built for Sustainable Homes
If you’re building, retrofitting, or scaling your eco-conscious lifestyle, MasterShield aligns with your goals:
✅ Reduces filter replacements and maintenance cycles
✅ Lowers tank sludge and anaerobic breakdown
✅ Helps maintain better water clarity from the very first drop
✅ Extends lifespan of cistern components and rainwater pumps
✅ Makes your whole system more efficient, less wasteful, and longer lasting
Pair It With Your Cistern or Barrel System
Whether you’re storing rain in a rain barrel, a buried cistern, or a multi-stage filtration hub, MasterShield is the roofline prefilter your system needs to stay clean and sustainable.
It’s the quiet but crucial first step in a closed-loop water reuse system:
Rain hits your roof
MasterShield filters it immediately
Clean water flows into your tank
You reuse it—waste-free, plastic-free, chlorine-free
Smart for the Planet. Easy for You.
With MasterShield, you don’t just stop gutter clogs—you:
Save water
Reduce runoff
Keep moss and microdebris out of ecosystems
And cut your chemical and filter waste
