Tacoma's Trusted Exterior Contractor — Roofing, Siding, Gutters & Windows
Tacoma sits at the south end of Puget Sound with direct exposure to weather systems sweeping in from the Olympic Mountains. The city's older housing stock — much of it 1910s–1960s — faces compounded challenges: decades of wet-weather cycling, moss-saturated roofs, and siding that was never designed for sustained marine moisture. Signature Exteriors brings the same WA-licensed, GAF Master Elite-certified expertise to Tacoma that we apply across the Puget Sound region. License SIGNAE*835N1.
Puget Sound Climate & Your Roof: What Tacoma Homeowners Need to Know
Tacoma averages 38+ inches of rain annually, with the bulk falling October through May. The combination of marine humidity and cool temperatures is ideal for moss and algae growth — your roof can go from clean to moss-covered in a single wet season if the shingles aren't algae-resistant.
- South Sound wind exposure: Tacoma Narrows weather brings sustained wind events that lift aging flashing and drive rain under lap siding. We use ice-and-water shield beyond code minimums at all vulnerable edges.
- Moss on aging shingle stock: Pre-2000 homes often have original or single-replacement asphalt without algae-resistant granules. Moss holds moisture against the shingle surface, accelerating granule loss and sheathing rot.
- Gutter overflows: Undersized 4" gutters — common on Tacoma's historic homes — overflow during atmospheric river events and saturate fascia and soffit. We upsize to 6" seamless gutters as standard.
Our Services
Roofing
Complete replacements, repairs, and new installations. Architectural shingles, metal roofing, low-slope membranes — systems engineered for Puget Sound's relentless rain and wind.
Siding
Fiber cement, engineered wood, and vinyl siding systems rated for Pacific Northwest moisture. We seal and flash every penetration — no wet-wall rot allowed.
Gutters
Oversized 6" seamless gutters for Puget Sound rainfall volumes. Guards, proper pitch, and downspout extension keep water away from your foundation.
Windows
Triple-pane and double-pane vinyl windows with low-E coatings to retain heat during gray Pacific Northwest winters. Properly flashed to stop water intrusion at the frame.
Storm Damage
Atmospheric river damage, wind-driven rain infiltration, fallen-tree impacts. We document, repair, and work with your insurance carrier.
Free Inspections
Licensed inspectors assess moss/lichen buildup, failing flashing, gutter capacity, and siding moisture intrusion. No cost, no obligation.
Tacoma Neighborhoods We Serve
- North End— Tacoma's most historic residential district. Queen Anne, Craftsman, and Tudor homes from 1900–1930. Steep roofs, original cedar siding, and architectural details demanding careful restoration work.
- Stadium District— Named for Stadium High School. Dense historic housing, many converted to rentals over decades. Deferred maintenance is common — we handle comprehensive exterior restoration.
- Proctor District— Walkable neighborhood center with older residential streets. Mix of 1920s bungalows and mid-century ranches. Moss on north-facing roofs is universal; gutter capacity is the secondary issue.
- South Tacoma— Larger lots, more mid-century construction. Many homes reaching or past first roof replacement age. We handle high-volume re-roofs efficiently with quality controls at each stage.
- Ruston / Browns Point— Waterfront and near-waterfront with maximum salt-air and wind exposure. Siding and fasteners see accelerated corrosion — we spec corrosion-resistant fasteners and appropriate product warranties.

Frequently Asked Questions
How long does moss take to damage a Tacoma roof?
Active moss colonies can degrade granule adhesion and hold persistent moisture against the shingle surface within 2–4 years. We see sheathing rot under heavy moss in as little as 5–7 years on older roofs. Early removal and algae-resistant replacement products prevent this.
Are 4-inch gutters adequate for Tacoma rain?
Rarely. Four-inch gutters reach capacity during moderate Puget Sound rainstorms and overflow at the fascia. We replace with 6-inch seamless aluminum gutters — the standard for Pacific Northwest rainfall rates — and add guards to prevent the debris-plugging that makes overflow worse.
What siding material holds up best in Tacoma?
Fiber cement (James Hardie or equivalent) is the gold standard for marine-climate siding. It's dimensionally stable in wet conditions, won't rot or harbor moss the way wood does, and carries a 30-year finish warranty. Engineered wood is an alternative with good performance if properly maintained.
Can you work with my insurance on storm damage?
Yes. We document damage with photos and measurements, provide a detailed scope of work, and can meet your insurance adjuster on-site. Most wind and water-damage claims in Tacoma are approvable — the key is thorough documentation before any repairs begin.
What's the WA contractor license for Signature Exteriors?
SIGNAE*835N1. You can verify at the Washington State Department of Labor & Industries website. We're also bonded and carry general liability and workers' compensation insurance.
How do I prevent wind-driven rain from getting under my siding?
Proper house wrap installation, correct lap spacing, and flashing at all penetrations and horizontal transitions. We inspect failed siding from outside and inside with a moisture meter before recommending an approach.
