Seattle’s persistent rain, heavy moss growth, wind storms, falling branches, and occasional snow load stress residential roofs over time, leading to rot, leaks, lifted materials, and underlayment failure.
When repairs are no longer effective, full roof replacement provides lasting protection, improved ventilation, and updated appearance. We serve residential homes in Seattle, Bellevue, Kirkland, Redmond, Renton, Issaquah, Mercer Island, Tacoma, Everett, and communities within a 50-mile radius.
We specialize exclusively in residential roof replacement for single-family homes, townhomes, and condominiums, using durable materials proven in the Pacific Northwest’s wet climate.
Service Advantages
Superior Moisture and Moss Resistance
New roofs with modern underlayment and algae-resistant materials better withstand constant dampness and organic growth common in our region.
Enhanced Ventilation and Energy Efficiency
Updated systems reduce attic moisture buildup and heat loss, helping control indoor humidity and energy costs in rainy, overcast weather.
Refreshed Curb Appeal
A clean, new roof dramatically improves your home’s look, boosting value in Seattle’s competitive housing market.
Long-Term Reliability
Quality installation with strong warranties delivers decades of worry-free performance against local weather challenges.
Key Replacement Components
Roof Decking
Existing decking is inspected and replaced where rot or weakness is found, ensuring a solid base.
Underlayment and Ice/Water Barrier
High-performance synthetic underlayment and self-adhering membranes protect against wind-driven rain and ice dams.
Flashing and Ventilation
New metal flashing and balanced ventilation systems seal penetrations and promote attic airflow.
Shingles or Shakes
Premium asphalt shingles, cedar shakes, or composite materials are installed for durability and regional style.
Edge and Ridge Details
Specialized starters, drip edges, and ridge caps provide extra protection at vulnerable transitions.
Gutter Integration
Gutters are realigned or upgraded for optimal drainage during heavy downpours.
Replacement Process Steps
Initial Consultation and Material Selection
We visit your home to evaluate the current roof, discuss style preferences, moss concerns, ventilation needs, and budget, then present suitable options with samples. We explain algae-resistant shingles, cedar treatments, and ventilation upgrades that address Seattle’s unique moisture challenges.
Permitting and Material Ordering
We handle all required permits from Seattle, King County, or surrounding jurisdictions. Materials are selected for local code compliance (including ventilation and seismic requirements) and ordered with timed delivery to keep the project on schedule.
Comprehensive Site Protection
Landscaping, windows, siding, decks, rain gardens, and driveways are thoroughly covered with heavy tarps and plywood shields. Dumpsters are placed conveniently, and safety measures protect your family, pets, and Puget Sound-sensitive plants.
Old Roof Tear-Off
Existing materials are carefully stripped down to the decking. Debris is contained with tarps and loaded directly into dumpsters to minimize impact on your yard and gardens common in Seattle homes.
Decking Repairs and Underlayment Installation
Decking is checked for rot—prevalent in damp climates—and damaged sections replaced. New synthetic underlayment is applied, with ice-and-water shield at eaves, valleys, and penetrations for superior protection against prolonged rain and winter ice.
New Roofing Material Application
Flashing, drip edges, and starters are installed first. Shingles, shakes, or composites are then applied row by row with precise alignment and proper fastening. Ventilation components (ridge vents, soffit vents) are integrated to combat moisture buildup.
Final Detailing, Cleanup, and Walkthrough
Ridge caps, hip covers, and accessory flashing complete the roof. Multiple magnetic sweeps collect nails, debris is removed, and the property is blown clean. We conduct a final quality inspection, then walk you through your new roof, sharing warranty details and moss-prevention tips.
Frequently Asked Questions
How do I know if my roof needs full replacement?
Signs include persistent leaks, widespread moss damage, curling/lifted shingles, rot in decking, or a roof over 20–30 years old. We’ll give you a thorough, honest assessment with photos to help you decide.
How long does roof replacement take in Seattle?
Most homes are completed in 3–7 days, weather permitting. We monitor forecasts closely and work efficiently with a full crew to minimize disruption.
Will the process be noisy or messy?
There will be noise during tear-off and installation, but we work normal hours and use extensive tarps plus daily cleanups. At completion, we leave your yard cleaner than we found it—many customers are impressed!
What materials are recommended for Seattle’s climate?
Asphalt architectural shingles with algae resistance are the most popular for cost and performance. Cedar shakes offer classic Northwest beauty (with proper treatment), while composites provide low-maintenance durability. We’ll show samples tailored to your home.
Can a new roof help with ventilation and moisture control?
Yes—one of the biggest benefits here! Proper ridge/soffit ventilation and moisture barriers reduce attic condensation and mildew risks common in our damp weather.
What warranties come with the replacement?
You receive full manufacturer warranties (often 30–50 years or lifetime) plus our comprehensive workmanship warranty. We register everything for you.
Do you handle permits and HOA requirements?
Yes—we manage all permitting and can assist with HOA submissions common in communities like Bellevue or Issaquah.
Is roof replacement available throughout the greater Seattle area?
We’d love to help! We serve residential homes within 50 miles, including Bellevue, Kirkland, Redmond, Renton, Issaquah, Mercer Island, Tacoma, Everett, and all surrounding communities.
