New roof installation in Seattle. new construction and full tear-off re-roofs. Shingles, metal, and cedar shake backed by a 10-year workmanship warranty.
A properly installed roof is the foundation of a dry, comfortable home. K Single Corp has installed over 15,000 roofs across King, Snohomish, and Pierce County since 2007. Whether you’re building a new home, replacing an aging roof, or upgrading to a premium material, our installation process is built around doing the job right, with no shortcuts, no overlays, and no compromises.
We install asphalt shingles, standing seam metal roofing, and cedar shake. Every installation starts with a full tear-off (on re-roofs), a thorough deck inspection, premium underlayment, and meticulous flashing details. The result is a roof that performs in the Pacific Northwest climate for decades.
When it’s time to replace your roof, we start from scratch. Our full tear-off process ensures nothing is hidden beneath the new material:
Step 1: Complete Removal. We strip the existing roofing down to the plywood decking. This lets us inspect every square foot of sheathing for rot, soft spots, and damage, problems that are invisible when you roof over existing layers.
Step 2: Deck Repair. Any rotted or damaged plywood is replaced with new sheathing. In the PNW, we commonly find moisture damage around valleys, eaves, and chimney areas. We fix it properly before anything else goes on.
Step 3: Underlayment & Ice Shield. We install synthetic underlayment across the entire roof and apply ice-and-water shield in vulnerable areas, valleys, eaves, around skylights, chimneys, and wall transitions. This is your second line of defense against water intrusion.
Step 4: Material Installation. Whether it’s architectural shingles, metal panels, or cedar shake, our crews follow manufacturer specifications precisely. Proper nailing patterns, correct exposure, aligned courses, and careful flashing work at every transition.
Step 5: Cleanup & Inspection. We run magnetic nail sweepers across your property, clean up all debris, and conduct a final inspection. We walk the finished roof with you and activate your 10-year workmanship warranty.

Architectural Asphalt Shingles. The most popular choice for PNW homes. We install premium shingles from Malarkey, CertainTeed, and GAF, featuring enhanced wind resistance, algae resistance, and impact ratings. Architectural shingles offer a dimensional look that mimics wood shake at a fraction of the cost and maintenance. Expect 30-50 years of performance depending on the product line.
Standing Seam Metal Roofing. The premium choice for homeowners who want a roof that lasts 50+ years with virtually zero maintenance. Standing seam panels shed rain and snow efficiently, resist moss growth, and handle PNW wind without lifting. Available in a wide range of colors and profiles. Higher upfront cost, but the lowest lifetime cost of any roofing material.
Cedar Shake. A classic Pacific Northwest aesthetic that’s been on homes in this region for over a century. We install premium cedar shake with proper ventilation and underlayment to maximize lifespan. Cedar requires more maintenance than other options (periodic cleaning and treatment), but nothing matches its natural beauty. Ideal for Craftsman, Tudor, and Pacific Northwest-style homes.
The best roofing material in the world will fail if it’s installed incorrectly. The most common causes of premature roof failure are installation errors, improper nailing, bad flashing details, inadequate ventilation, and missing ice-and-water shield. These mistakes don’t show up immediately, but they lead to leaks, blow-offs, and shortened roof life within a few years.
At K Single Corp, every crew member is trained in manufacturer-specific installation methods. We follow the specifications exactly, because that’s what activates the manufacturer’s warranty and ensures long-term performance. Our 10-year workmanship warranty backs up our commitment to getting it right.
We install roofs across the Puget Sound region, from Everett to Tacoma, from Seattle to Issaquah, and everywhere in between. No matter where you are in King, Snohomish, or Pierce County, we deliver the same quality installation and the same 10-year warranty.

Our crews follow a strict installation sequence: tear-off, deck inspection and repair, ice-and-water shield, synthetic underlayment, drip edge, then shingles installed to manufacturer spec. Every step is documented and inspected.
What's under your shingles determines how long your roof actually lasts. We use premium synthetic underlayment, proper flashing at every wall and chimney transition, and ice-and-water shield in all valleys and vulnerable areas.

A full tear-off and installation on a typical residential home takes 2-5 days. New construction roofing depends on the builder's schedule but typically takes 2-4 days once we're on site. Larger homes, complex roof lines, and material choices (cedar shake takes longer than asphalt shingles) can extend the timeline. Weather delays are always a possibility in the PNW, but we schedule strategically.
For most Seattle-area homes, we recommend architectural asphalt shingles from Malarkey or CertainTeed, they offer the best balance of durability, appearance, and value in our climate. For homeowners wanting a longer-lasting option, standing seam metal roofing handles PNW rain exceptionally well and lasts 50+ years. Cedar shake is a classic Pacific Northwest look but requires more maintenance. We'll walk you through the pros and cons during your estimate.
Yes. We pull all required building permits for every project, whether it's a tear-off re-roof or new construction. Permit requirements vary by jurisdiction, Seattle, Bellevue, Kirkland, and other cities each have their own processes and fees. We handle the paperwork, pay the fees, and schedule the inspections so you don't have to.
A re-roof involves a full tear-off of the existing roofing material down to the deck, inspection and repair of the sheathing, installation of new underlayment, and then new roofing material. An overlay (roofing over the existing layer) skips the tear-off. We never do overlays, they hide problems, void most warranties, add unnecessary weight, and don't last as long. Every K Single Corp installation starts with a clean deck.
New roof costs depend on home size, material, and complexity. Asphalt shingle roofs typically range from $8,000 to $20,000 for most homes. Standing seam metal roofing runs $15,000 to $35,000+. Cedar shake installations range from $20,000 to $40,000+. We provide detailed, itemized estimates so you know exactly what you're paying for, no hidden fees or surprise charges.
Yes. We partner with builders and general contractors across the Puget Sound for new construction roofing. We understand the sequencing and coordination required on new builds, we show up on schedule, work efficiently with other trades, and meet builder timelines. We currently work with several builders in King and Snohomish County.
Our 10-year workmanship warranty covers all labor and installation defects on every roof we install. This is separate from and in addition to the manufacturer's material warranty, which typically ranges from 30 to 50 years for architectural shingles and up to lifetime for premium metal roofing. If anything related to our installation fails within 10 years, we fix it at no cost to you.
We don't install roofing materials in active rain, moisture trapped under shingles or membranes causes long-term problems. However, we're experts at working around PNW weather. We monitor forecasts closely, schedule work during dry windows, and can tarp and protect a partially completed roof if weather moves in unexpectedly. Living in the Pacific Northwest means being flexible, and we've been doing it since 2007.
