Trusted roofing and exterior contractor serving Redmond and the surrounding area since 2007. Free estimates, 10-year workmanship warranty, fully licensed and insured.
Redmond is home to approximately 87,000 residents and widely recognized as the technology capital of the Pacific Northwest, anchored by Microsoft’s global headquarters in the Overlake neighborhood and home to a concentration of tech companies that drives one of the strongest local economies in Washington State. But beyond the corporate campuses and the buzz of innovation, Redmond is a city of well-maintained residential neighborhoods, excellent schools, expansive parks like Marymoor Park along the Sammamish River, and a growing downtown that retains its small-city character despite decades of rapid growth.
K Single Corp has served Redmond homeowners and businesses since 2007, bringing our commitment to quality craftsmanship, transparent pricing, and reliable service to every neighborhood in the city. With over 15,000 projects completed across the Puget Sound region and our WA License #KSINGSC842B3, we understand the specific roofing demands that Redmond’s Eastside climate, affluent housing stock, and discerning homeowners require.
Redmond’s Eastside location creates roofing conditions that differ meaningfully from Seattle and western Puget Sound communities. Understanding these differences is essential for proper material selection, installation techniques, and long-term roof performance.
Eastside Temperature Extremes. Redmond sits in a transitional zone between the Puget Sound marine climate and the more continental climate of the Cascade foothills. This translates to wider temperature swings than Seattle, colder winters with frequent overnight freezing and hotter summers with temperatures regularly exceeding 85 degrees. The cumulative effect of these thermal cycles stresses roofing materials at every seam, flashing point, and penetration. We address this with flexible underlayments, cold-weather-rated sealants, and ice and water shield membrane at critical juncture points.
Freeze-Thaw Cycling. During Redmond’s winter months, daytime temperatures may rise above freezing while overnight lows drop into the upper 20s. This daily freeze-thaw cycle allows moisture to penetrate small gaps, expand when frozen, and gradually widen those openings. Over years, this process deteriorates flashings, lifts shingle edges, and compromises sealant beads. Proper installation techniques that account for freeze-thaw conditions are not optional on Redmond roofs, they are essential.
Occasional Heavy Snow. While Redmond does not receive consistent snowfall, the Eastside is more susceptible to heavier snow events than western Seattle. Several inches of wet, heavy Pacific Northwest snow can accumulate on roofs, creating substantial loads that stress structural elements and can cause ice damming at eaves if insulation and ventilation are inadequate. We assess attic ventilation on every Redmond project and recommend upgrades when necessary.
Moss and Tree Debris. Like all Eastside communities, Redmond’s mature tree canopy, particularly in neighborhoods like Idylwood, Bear Creek, and Education Hill, creates persistent moss, needle, and leaf debris challenges. The combination of consistent rainfall, moderate temperatures, and shade creates ideal conditions for moss colonization on composition roofing surfaces.
Tech-Savvy Transparency. Redmond homeowners tend to research thoroughly before making major home improvement decisions. We meet that expectation with detailed, itemized estimates that show exactly what is included, clear timelines, documented material specifications, and responsive communication throughout every project. Our online reviews and documented project history give data-driven homeowners the confidence to choose K Single Corp.
Premium Material Expertise. Redmond’s affluent housing market demands material options that match the quality of the homes they protect. We offer the full spectrum of roofing materials, from cost-effective Malarkey Vista AR architectural shingles to premium CertainTeed Grand Manor designer shingles to standing seam metal in over 20 colors and profiles. We help Redmond homeowners select the material that best balances their performance requirements, aesthetic preferences, and budget.
Eastside Climate Knowledge. Our extensive experience across Redmond, Bellevue, Kirkland, Sammamish, and Issaquah gives us deep understanding of Eastside-specific roofing requirements. We know which materials perform best in freeze-thaw conditions, which installation techniques prevent ice damming, and how to manage moss in Redmond’s tree-heavy neighborhoods. This local knowledge translates to longer-lasting roofs and fewer maintenance issues.
HOA and Multi-Family Experience. Redmond has a significant inventory of townhome and condominium communities managed by homeowner associations, particularly in Overlake, Grass Lawn, and Southeast Redmond. We work regularly with HOA boards and property management companies, managing multi-unit projects efficiently while meeting architectural guidelines and maintaining communication with all stakeholders.
Architectural Composition Shingles remain the standard choice for most Redmond homes. We recommend and install Malarkey architectural shingles featuring polymer-modified asphalt that provides enhanced flexibility in cold temperatures, superior moss and algae resistance, and excellent wind performance. For Redmond’s climate, the cold-temperature flexibility is particularly valuable, standard oxidized-asphalt shingles become brittle in freezing temperatures and are more prone to cracking and wind damage during cold-weather storms.
Standing Seam Metal Roofing is an excellent fit for Redmond homes, especially given the climate considerations. Metal naturally sheds snow, resists freeze-thaw damage, prevents moss attachment, and provides superior wind performance. We install metal roofing in contemporary profiles and colors that complement Redmond’s mix of modern and traditional residential architecture. The initial higher investment in metal pays for itself through dramatically reduced maintenance and a lifespan two to three times longer than composition shingles.
Flat and Low-Slope Systems serve Redmond’s commercial properties, multi-family buildings, and contemporary residential designs with flat or minimal-slope roof sections. We install TPO, PVC, and modified bitumen systems rated for the Eastside’s temperature extremes and designed for proper drainage in our wet climate.

Local expertise across Redmond's diverse communities.
Redmond's revitalizing downtown core blends historic charm with modern development near the Redmond Town Center and the Sammamish River Trail. A mix of older commercial buildings, renovated homes from the 1950s-1970s, and new mixed-use construction creates diverse roofing needs. We handle everything from flat-roof commercial systems on retail buildings to residential re-roofing on the single-family homes that still dot the downtown area.
One of Redmond's most established residential neighborhoods, Education Hill features homes built from the 1960s through 1990s on gently rolling terrain above downtown. The neighborhood takes its name from the concentration of schools in the area. Many homes here are on their second or third roof, and we frequently encounter inadequate original ventilation systems and deteriorated deck sheathing that require attention during replacement.
The tech employment hub of Redmond, Overlake is home to Microsoft's sprawling campus and surrounded by a mix of apartment complexes, townhomes, and single-family neighborhoods. We serve both the commercial properties in the Overlake corridor and the residential communities surrounding them. Multi-family roofing projects for HOA-managed townhome communities are a significant portion of our Overlake work.
Quiet residential neighborhood in southwest Redmond near the border with Bellevue, featuring mid-century homes on mature, tree-covered lots. Idylwood's heavy canopy of Douglas fir and western red cedar creates persistent moss and debris issues similar to neighboring Bridle Trails. Homeowners here value premium materials that complement the neighborhood's established, upscale character.
Residential area in northeast Redmond along the Bear Creek corridor, with homes ranging from 1980s suburban development to newer luxury construction. The creek and surrounding wetlands create higher ambient moisture levels that accelerate moss growth on nearby roofs. Proper drainage and ventilation are especially important for Bear Creek properties given the local moisture conditions.
Centrally located Redmond neighborhood with homes primarily from the 1970s and 1980s, many of which feature original or second-generation composition shingle roofs approaching end of life. Grass Lawn's relatively flat terrain and moderate tree coverage make it an efficient area for straightforward residential re-roofing projects. This is one of our most active Redmond neighborhoods for full roof replacements.
Established neighborhood in western Redmond near Willows Road and the Sammamish River, with a mix of 1960s-1980s homes and newer construction along the expanding tech corridor. Willows properties range from modest ranch-style homes to larger custom builds, creating a wide range of project scopes. Proximity to the river contributes to higher humidity and persistent dampness during the wet season.
Newer residential development area east of Marymoor Park along the Sammamish River, featuring homes built from the 1990s through 2010s. Many homes in Southeast Redmond are approaching their first roof replacement as original builder-grade three-tab shingles reach the 25-30 year mark. Upgrading from three-tab to architectural shingles is the most common project type in this area.
Redmond requires a building permit for all roof replacements and significant roof repairs. Permits are processed through the City of Redmond Development Services Division, located at Redmond City Hall, 15670 NE 85th Street. Residential re-roofing permits typically cost $250-$500 depending on project scope and valuation. Standard over-the-counter permits for straightforward residential tear-off-and-replace projects are usually issued within 1-5 business days. Redmond enforces a two-layer maximum for roofing materials, requiring full tear-off on homes with two existing layers. A final inspection by a city building inspector is required after installation is complete. K Single Corp manages the entire permit process for Redmond homeowners, including application preparation, fee payment, and scheduling the final inspection.
Redmond receives approximately 36 inches of rain annually, with the majority falling between October and April. Positioned further from the Puget Sound than Seattle, Redmond experiences more continental weather influence, resulting in colder winter temperatures that regularly drop below freezing. Overnight lows in the upper 20s during December and January create freeze-thaw cycles that stress roofing materials, particularly at flashings and in roof valleys where ice can accumulate. Summer temperatures can reach the mid-to-upper 80s, creating significant thermal expansion differentials over the course of a year. Redmond's eastern location on the Eastside means it occasionally receives heavier snowfall events than western Seattle neighborhoods, with several inches of accumulation possible during winter storms. Wind exposure varies by neighborhood, with elevated areas like Education Hill experiencing stronger gusts than valley-floor locations near the Sammamish River.

A residential roof replacement in Redmond typically costs $12,000-$32,000 depending on home size, material selection, roof complexity, and whether deck repairs are needed. Redmond homes tend to be well-maintained with higher-than-average square footage, which increases both material quantities and labor time. Composition architectural shingles run $4.50-$7.50 per square foot installed, and standing seam metal ranges from $9-$14 per square foot. We provide free, detailed estimates with complete line-item breakdowns.
Yes. The City of Redmond requires a building permit for all roof replacements, processed through their Development Services Division at City Hall on NE 85th Street. K Single Corp handles the entire permitting process, including application, fees, and final inspection coordination. Permits typically cost $250-$500 and are processed within 1-5 business days for standard residential projects. We always secure permits before beginning any work.
For most Redmond homes, we recommend Malarkey architectural shingles with polymer-modified asphalt for their superior resistance to moss, algae, and cold-temperature cracking, all important factors in Redmond's Eastside climate. For homeowners seeking maximum longevity and minimal maintenance, standing seam metal roofing is an excellent choice that eliminates moss concerns entirely and handles Redmond's occasional snow loads without issue.
Redmond's position east of Lake Washington means colder winter temperatures than Seattle proper. Overnight freezing creates freeze-thaw cycles where moisture that has seeped into small cracks expands when it freezes, widening those cracks over time. This accelerates deterioration at flashings, in valleys, and around pipe boots. We use flexible, cold-weather-rated underlayments and sealants specifically designed for Eastside conditions, and we install ice and water shield membrane in all valleys and at eaves on Redmond projects.
Absolutely. We serve the entire Overlake area, including the residential neighborhoods surrounding Microsoft's campus, the townhome communities along 156th Avenue NE, and the single-family homes throughout the broader Overlake neighborhood. Many Overlake homeowners are tech professionals who research extensively before choosing a contractor, our transparent estimates, documented track record, and online reviews consistently earn their trust.
Most residential roof replacements in Redmond take 2-4 days depending on roof size, complexity, and weather conditions. Standard single-story homes with simple roof planes can be completed in 1-2 days, while larger multi-story homes with complex rooflines, dormers, or skylights may take 3-5 days. We always secure the roof each evening if the project extends over multiple days, and we monitor weather forecasts to schedule work during dry windows.
Yes, we frequently handle townhome and condominium roofing projects throughout Redmond, particularly in HOA-managed communities in Overlake, Grass Lawn, and Southeast Redmond. We work directly with HOA boards and property managers, coordinate multi-unit scheduling to minimize disruption, and ensure all work meets both city code and HOA architectural standards. Our experience with multi-family projects means efficient execution and consistent quality across all units.
Yes, we provide same-day emergency response for active leaks, storm damage, and fallen-tree impacts throughout Redmond. Our emergency services include temporary tarping to stop active water intrusion, debris removal, and damage assessment. We then coordinate permanent repairs or replacement, including insurance claim assistance if applicable. Call us at (206) 659-4349 for immediate emergency service.
In Redmond's Eastside climate, architectural composition shingles typically last 22-30 years with proper maintenance, including regular moss treatment, gutter cleaning, and debris removal. Standing seam metal roofing can last 40-60 years or more with minimal maintenance. Redmond's colder winters and freeze-thaw cycling can shorten the lifespan of poorly installed or lower-quality materials, which is why we use premium products and installation techniques rated for Eastside conditions.
We recommend annual roof inspections, ideally in spring after winter weather has passed. Keep gutters clear of debris, trim tree branches to maintain at least six feet of clearance from roof surfaces, and address moss growth promptly with zinc strip installation or professional soft-wash treatment. Never pressure wash a composition shingle roof. We offer maintenance guidance with every project and are always available for follow-up inspections during our 10-year warranty period.
