Asphalt shingles are the most common roofing material in Seattle homes, offering affordability and versatility, but constant moisture, moss growth, heavy rain, wind, and falling debris cause curling, granule loss, lifting, cracking, or widespread deterioration. When repairs can’t keep up, full shingle replacement delivers renewed protection, moss resistance, and a clean, modern appearance. We serve residential homes in Seattle, Bellevue, Kirkland, Redmond, Renton, Issaquah, Mercer Island, Tacoma, Everett, and communities within a 50-mile radius.
We focus exclusively on residential shingle replacement for single-family homes, townhomes, and condominiums, using high-quality, algae-resistant shingles designed for the Pacific Northwest’s damp climate.
Service Advantages
Enhanced Moss and Moisture Resistance
New algae-resistant shingles slow moss and streak development while modern underlayment better protects against prolonged rain and humidity.
Improved Ventilation and Energy Performance
Updated systems reduce attic moisture buildup and improve airflow, helping control indoor humidity and energy use in overcast, rainy weather.
Refreshed Home Appearance
A uniform new shingle roof instantly brightens your home, boosting curb appeal in tree-lined, rainy neighborhoods.
Long-Term Durability
Quality materials and expert installation, backed by strong warranties, provide reliable performance for decades in Seattle conditions.
Key Replacement Components
Roof Decking
Existing decking is inspected and repaired or replaced to eliminate rot common in damp climates.
Underlayment and Barriers
Synthetic underlayment and ice-and-water shield in eaves and valleys guard against wind-driven rain and winter ice.
Drip Edge and Flashing
New metal drip edges and flashing create seamless transitions and watertight seals.
Asphalt Shingles
Premium architectural shingles with algae-resistant granules are installed for durability and beauty.
Starter Strips and Ridge Caps
Specialized starters and matching ridge shingles protect edges and peaks from wind uplift.
Ventilation System
Ridge vents and soffit intake ensure balanced airflow to prevent condensation and mildew.
Replacement Process Steps
Initial Consultation and Shingle Selection
We visit your home to assess current damage, measure the roof, and discuss color, style, algae resistance, and ventilation upgrades. We bring shingle samples and explain options that perform best against Seattle’s moss and moisture challenges.
Permitting and Material Preparation
We handle all required permits with Seattle or surrounding county authorities. Materials—including algae-resistant shingles and high-performance underlayment—are ordered and scheduled for delivery to align with the project timeline.
Site Protection Setup
Landscaping, windows, siding, decks, rain gardens, and driveways are covered with heavy tarps and plywood shields. Dumpsters are positioned thoughtfully to protect plants and minimize disruption.
Complete Old Shingle Tear-Off
All existing shingles, underlayment, and old flashing are removed down to the decking. Debris is controlled with tarps and loaded directly into dumpsters to keep your yard clean throughout the process.
Decking Repairs and Underlayment Installation
Decking is inspected for rot or weakness; compromised areas are replaced. New synthetic underlayment is applied across the roof, with self-adhering ice-and-water shield at eaves, valleys, and penetrations for maximum moisture protection.
New Shingle Application
Drip edges, starters, and valley flashing are installed first. Algae-resistant architectural shingles are then laid row by row with precise alignment and proper nailing patterns to maximize wind and water resistance.
Final Detailing, Ventilation, and Cleanup
Ridge vents, ridge caps, and accessory flashing complete the system. Multiple magnetic sweeps collect nails, debris is removed, and the property is blown clean. We perform a final quality check, then walk you through your new roof with before-and-after photos and warranty information.
Frequently Asked Questions
When should I replace my shingles instead of continuing repairs?
If you’re dealing with widespread moss damage, curling, granule loss in gutters, multiple leaks, or a roof over 20–25 years old, replacement is often the smarter choice. We’ll provide a clear, honest evaluation to help you decide!
How long does shingle replacement take in Seattle?
Most homes are completed in 3–5 days, weather dependent. We watch forecasts carefully and work efficiently with a full crew to stay on schedule.
Will the project be noisy or leave my yard messy?
There will be noise during tear-off and nailing, but we work regular daytime hours and use extensive tarps plus daily cleanups. At the end, we do thorough magnetic sweeps—customers often say their yard looks great when we’re finished!
What shingles are best for Seattle’s wet climate?
Architectural shingles with copper or zinc algae-resistant granules are the top recommendation—they slow moss and streak growth significantly. We also offer premium options with enhanced ventilation features. We’ll show you samples that suit your home’s style.
Can new shingles help prevent moss growth?
Yes! Modern algae-resistant granules containing copper or zinc release particles that inhibit moss and algae for years—many Seattle homeowners notice a big difference compared to older roofs.
What warranties come with shingle replacement?
You receive full manufacturer warranties (typically 30–50 years or lifetime, depending on the product) plus our workmanship warranty. We handle registration so coverage starts right away.
Do you handle permits and HOA approvals?
Absolutely—we manage all permitting and can assist with HOA color or style requirements common in neighborhoods like Bellevue or Kirkland.
Do you serve homes throughout the greater Seattle area?
We’d be happy to! We provide shingle replacement for residential homes within 50 miles, including Bellevue, Kirkland, Redmond, Renton, Issaquah, Mercer Island, Tacoma, Everett, and all surrounding communities.
