Chemical Moss Eradication for Tacoma’s Composite Roofs

Tacoma is a beautiful, gritty port city featuring a massive inventory of homes constantly battling a brutal, corrosive combination of marine moisture, heavy port-city industrial exhaust, and relentless Pacific Northwest rainfall. This highly specific urban environment creates a sticky, stubborn layer of black grime on your roof. This port fallout acts as the perfect anchor, allowing destructive moss spores and green algae to rapidly colonize your composite shingles.

Catching this growth early is the absolute key to preserving your home’s value. A new roof installation easily costs upwards of $20,000. Legacy Gutter Cleaning brings commercial-grade, preventative moss treatments directly to your Tacoma doorstep, neutralizing the spores and stopping the rot before it requires a heavy, expensive manual extraction.

Protecting Your Investment Chemically

Hiring an untrained contractor to blast your roof with a pressure washer is a guaranteed way to shorten its lifespan. The experts at the National Roofing Contractors Association (NRCA) agree that harsh abrasions and high water pressure permanently damage exterior surfaces, stripping the UV-reflective granules right off the asphalt and leaving the fiberglass backing exposed.

We completely abandon brute force. Our strike teams begin the deployment with a full roof blow-off, removing all surface debris, urban exhaust buildup, and trapped moisture pockets. We then apply a heavy layer of commercial-grade moss killer specifically to the peaks and structural ridges of your home. Over the following 6 to 8 weeks, the consistent Tacoma rainfall washes the chemistry down the slope, saturating the shingle overlaps. This safely kills any active spores and establishes a protective barrier that stops regrowth for 6 to 9 months.

Hometown Comprehensive Maintenance

As our chemical treatment effectively kills the remaining moss, the dead organic matter will slowly wash down into your drainage system over the next few months. To prevent massive blockages, ensure your property is secured by pairing your roof treatment with our expert downspout and gutter clearing. If the urban grime has also stained your exterior walls, our crews can seamlessly perform a safe siding soft wash.
