Trusted roofing and exterior contractor serving Seattle and the surrounding area since 2007. Free estimates, 10-year workmanship warranty, fully licensed and insured.
Seattle is the Pacific Northwest’s largest city, home to more than 801,000 residents across a landscape of hills, waterways, and neighborhoods that each carry distinct architectural character and roofing challenges. From the craftsman bungalows of Ballard and Columbia City to the hilltop mansions of Queen Anne and Magnolia, from the dense townhome developments of Capitol Hill to the waterfront-facing bluffs of West Seattle, the city’s residential roofing landscape is as diverse as its population. No two Seattle neighborhoods present the same set of conditions, and no single roofing approach works everywhere.
This complexity is what makes Seattle the most demanding roofing market in King County. Contractors working in Seattle must navigate a broader range of housing types, construction eras, lot configurations, permitting requirements, and weather exposures than anywhere else in the region. The city’s building code and permit process through SDCI is more involved than suburban jurisdictions. Historic districts add additional review layers. Steep hillside lots in Queen Anne, Capitol Hill, and Beacon Hill create access and logistics challenges that flat-lot suburban projects never encounter. And the city’s varied topography means that a home on a Queen Anne hilltop faces fundamentally different weather conditions than a home in the Rainier Valley floor, even though they are separated by just a few miles.
K Single Corp has been serving Seattle homeowners and businesses from our Burien headquarters since 2007. Our South King County base puts us 15-25 minutes from most Seattle neighborhoods, and our crews work across the city daily. We have built deep experience with Seattle’s unique challenges (historic home craftsmanship, steep-lot logistics, SDCI permitting, and neighborhood-specific weather conditions) through years of consistent project work throughout the city.
Seattle homeowners are discerning, research-driven, and expect contractors to match their standards. K Single Corp has earned a strong reputation across Seattle’s neighborhoods by delivering exactly what we promise: quality work, transparent pricing, and a warranty that means something.
Historic Home Expertise. A significant portion of Seattle’s housing stock predates 1950. These homes (craftsmen, Victorians, Tudors, colonials, and mid-century moderns) have specific roofing requirements that go beyond material selection. Roof geometry is often complex with multiple hips, valleys, dormers, and intersections that require precise flashing work. Substrate conditions may include original skip-sheathing or early plywood that needs assessment. And in designated historic districts, material choices must satisfy Department of Neighborhoods review. Our crews have the experience to handle all of these considerations.
Urban Project Management. Roofing in Seattle is not just about installing materials. It is about managing logistics in a dense urban environment. Material delivery to steep or narrow lots, dumpster placement on crowded streets, debris containment to protect neighboring properties, and noise management during early-morning crew hours all require planning. We coordinate these details before the project begins so the installation itself proceeds smoothly.
Comprehensive Material Range. Seattle’s diverse housing stock demands a wide material library. We carry architectural composition shingles from Malarkey and CertainTeed in dozens of colors and profiles, standing seam metal roofing in 20-plus colors for modern and exposed applications, and commercial flat-roof systems including TPO and PVC for Seattle’s many multi-family and commercial buildings. For historic homes, we source specialty products that honor architectural character while delivering modern performance.
Transparent Pricing. Seattle roofing costs vary widely based on home size, complexity, access, and materials. We provide itemized estimates that account for every variable with no vague allowances and no ambiguous line items. You see exactly what each component costs, which makes comparing proposals from different contractors straightforward and informed.
10-Year Workmanship Warranty. Our 10-year workmanship warranty backed by WA License #KSINGSC842B3 covers every Seattle project. This is particularly valuable for complex installations on historic homes and steep-lot properties where installation quality is paramount. If an issue arises from our workmanship within a decade, we address it at no cost.

Local expertise across Seattle's diverse communities.
Perched on a peninsula between Puget Sound and the Duwamish Waterway, West Seattle is one of the city's most distinctive residential areas. Housing ranges from early 1900s craftsmen in The Junction to mid-century ramblers in Arbor Heights and newer construction near Alki Beach. The westward-facing bluffs take direct hits from Puget Sound storms, making wind-rated roofing and proper flashing essential.
Originally a Scandinavian fishing village, Ballard combines historic homes from the early 1900s with an explosion of modern townhomes and apartment buildings. The neighborhood's older homes frequently have original cedar shake roofs, complex roof lines, and dormer details that require experienced craftsmanship for replacement. Ballard's proximity to Puget Sound means marine moisture and wind exposure are constant factors.
One of Seattle's densest neighborhoods, Capitol Hill features a remarkable mix of historic apartment buildings, century-old craftsmen and Victorians, and modern mid-rise construction. Roofing projects here often involve steep lots, limited staging access, and historically sensitive structures that demand careful material selection and precise workmanship to maintain architectural character.
A vibrant residential neighborhood north of the Lake Washington Ship Canal, Fremont features charming homes from the 1900s-40s alongside newer infill construction. Many of these older homes have complex hip-and-valley roof designs, multiple dormers, and tight lot lines that require careful planning for material staging and debris removal. Moss growth is heavy under Fremont's mature tree canopy.
Divided into Upper and Lower Queen Anne, this hillside neighborhood contains some of Seattle's most iconic residential architecture. Upper Queen Anne's hilltop homes face extreme wind exposure with panoramic views, while Lower Queen Anne's denser development presents access and staging challenges. Many Queen Anne homes are on the historic register or in conservation districts, requiring roofing materials that respect the architectural heritage.
An affluent residential neighborhood on a bluff overlooking Puget Sound, Elliott Bay, and the Olympic Mountains, Magnolia homes face severe marine weather exposure. High winds, salt air, and driving rain test every roofing installation. Many homes here are large, with complex roof lines and premium material expectations. We recommend standing seam metal or high-wind-rated architectural shingles for Magnolia properties.
A diverse, historic neighborhood in southeast Seattle, Columbia City features craftsman homes from the 1900s-20s alongside post-war bungalows and newer development. The neighborhood's established tree canopy creates shaded conditions that promote aggressive moss growth. Many older homes have been renovated but retain original or aging roof systems that are overdue for modern replacement.
Running along a ridge between Interstate 5 and Rainier Valley, Beacon Hill offers sweeping views from its elevated position. Homes range from early 1900s construction to recent infill townhomes. The ridgeline location creates higher wind exposure than valley-floor neighborhoods, and the diverse housing stock (from tiny bungalows to multi-family buildings) means roofing projects vary dramatically in scope and complexity.
Seattle requires a building permit for all roof replacements. Permits are processed through the Seattle Department of Construction and Inspections (SDCI) at the Permit Center (700 5th Avenue, Suite 2000). Seattle's permitting process is more complex than suburban jurisdictions. Residential roofing permits typically cost $300-$600 depending on project scope and valuation. Standard review takes 4-8 weeks, though SDCI offers an express permit path for straightforward re-roofing projects that can reduce turnaround to 1-2 weeks. Homes in designated historic districts or landmark structures require additional review through the Department of Neighborhoods. The city requires a final inspection after installation. K Single Corp manages the full Seattle permitting process, including the more complex applications for historic properties, so homeowners can focus on choosing materials while we handle the bureaucracy.
Seattle receives approximately 37 inches of rain annually, distributed primarily between October and May with relatively dry summers. Winter temperatures average in the mid-30s to mid-40s, while summer highs reach the mid-70s to low 80s, though recent heat dome events have pushed temperatures above 100 degrees, creating thermal stress on roofing materials not traditionally tested at those extremes. Seattle's varied topography creates diverse microclimates: hilltop neighborhoods like Queen Anne, Beacon Hill, and upper West Seattle experience significantly higher wind exposure than valley-floor areas, while waterfront neighborhoods face marine moisture and salt air. The city averages 150-160 overcast days per year, keeping roof surfaces damp and promoting moss growth that is arguably Seattle's most common roofing challenge. Wind events during November through February can produce gusts exceeding 60 mph, particularly on exposed hilltops and bluffs.

Residential roof replacements in Seattle range widely from $10,000 to $45,000 depending on home size, roof complexity, material selection, and access challenges. Seattle's housing stock includes everything from 800-square-foot bungalows to 4,000-square-foot historic homes with complex multi-level roof systems. Most mid-sized Seattle homes fall in the $12,000-$25,000 range for architectural composition shingles. Standing seam metal runs $9-$14 per square foot. Historic home projects with custom details run higher. Every estimate is free and fully itemized.
Yes. The City of Seattle requires a building permit for all roof replacements, processed through the Seattle Department of Construction and Inspections (SDCI). Permits cost $300-$600 and take 1-8 weeks depending on the permit path and property type. Homes in designated historic districts require additional review. K Single Corp manages all Seattle permitting (standard, express, and historic district applications) as part of our project service.
Yes. Seattle has a significant inventory of historic homes (craftsmen, Victorians, Tudors, and colonial revivals) from the early 1900s through the 1940s. We have extensive experience with these properties, including navigating Department of Neighborhoods review for landmarked structures, matching appropriate roofing materials to architectural period, working with complex roof geometries, and preserving character-defining features. Our work on historic Seattle homes reflects respect for the architecture and precision in execution.
Seattle presents challenges that suburban communities do not. Steep lots with limited access for material delivery and debris removal are common in hillside neighborhoods. Historic structures require period-appropriate materials and sometimes specialized permit review. Dense urban construction means tight lot lines and close neighbors, requiring careful debris management. And Seattle's diverse microclimates, from exposed hilltops to sheltered valleys, mean material and installation specifications should vary by neighborhood.
We serve residential and commercial properties throughout Seattle, from West Seattle and Beacon Hill to Ballard, Fremont, Queen Anne, Magnolia, Capitol Hill, Columbia City, and all neighborhoods in between. While our headquarters is in Burien in South King County, our crews work in Seattle daily and are familiar with the city's permitting process, neighborhood conditions, and the specific challenges that Seattle properties present.
For most Seattle homes, architectural composition shingles from Malarkey or CertainTeed provide the best balance of performance, aesthetics, and value. We specifically recommend products with algae-resistant technology given Seattle's moss-prone climate. For exposed hilltop and waterfront homes in Queen Anne, Magnolia, and West Seattle, standing seam metal roofing offers superior wind resistance and a 50-plus year lifespan. For historic homes, we match materials to architectural period while delivering modern performance.
Many Seattle neighborhoods, Capitol Hill, Queen Anne, Beacon Hill, parts of West Seattle, feature steep lots that complicate material delivery, debris removal, and crew access. We plan logistics for these projects carefully, using specialized equipment for material transport where driveways are inadequate, coordinating street-level dumpster placement with the city, and employing safety systems appropriate for steep-slope work. These challenges are routine for our crews, not exceptional.
Yes. We provide same-day emergency response for active leaks and storm damage throughout Seattle. Our Burien headquarters is approximately 15-25 minutes from most Seattle neighborhoods. For emergencies, we perform temporary tarping and repairs to stop active water entry, followed by a full damage assessment and permanent repair plan. Call (206) 659-4349 any time for emergency service.
Moss is arguably the single most common roofing issue in Seattle. The city's 150-plus overcast days per year, persistent moisture, and mature urban tree canopy create ideal conditions for moss growth on virtually every north-facing and shaded roof surface. Unchecked moss lifts shingle edges, traps moisture, accelerates granule loss, and can cause premature roof failure. We offer moss treatment services and install zinc or copper prevention strips during replacements. We also recommend algae-resistant shingles as standard for all Seattle installations.
Every K Single Corp project in Seattle carries our 10-year workmanship warranty, backed by WA License #KSINGSC842B3. This covers all installation-related defects for a full decade.
