FAQ

Common Questions

Answers to the most common roofing questions from Seattle homeowners.

How much does a new roof cost in Seattle?
A composition shingle roof replacement on an average Seattle-area home runs $8,000–$15,000. Metal roofing ranges from $15,000–$30,000. The final price depends on roof size, pitch, material grade, and whether tear-off is needed. Use our roofing calculator for an instant estimate.
How do I choose the best roofer in Seattle?
Check Washington State contractor licensing at lni.wa.gov, verify proof of insurance, read Google review history, confirm BBB accreditation, ask about manufacturer certifications, and compare warranty terms. Request references from recent local projects.
What roofing materials work best in the Pacific Northwest?
Composition shingles are the most popular choice (20–30 year lifespan, best value). Metal roofing is ideal for heavy rain and longevity (40–70 years). Cedar shake offers traditional PNW curb appeal (30–40 years). Flat/TPO systems work best for commercial and low-slope residential roofs.
How long does a roof replacement take?
Most residential roofs take 1–3 days. Larger or complex roofs (steep pitch, multiple layers, cedar shake) can take 3–5 days. Timelines are weather-dependent in Seattle, and we schedule around forecasts to keep your home protected.
Does K Single Corp offer financing?
Yes. We offer multiple financing options for qualified homeowners. See financing options or ask about payment plans during your free estimate.
What does your roofing warranty cover?
Our 10-year workmanship warranty covers all installation defects. Manufacturer material warranties provide up to 30 years of coverage depending on the product selected. Both warranties activate upon project completion.
How do I know if I need a repair or full replacement?
Key factors: age of your roof (20+ years usually means replacement), extent of damage, number of previous repairs, and condition of the decking and underlayment. We provide honest assessments. If a repair will last, we'll tell you.
Do you handle emergency roof repairs?
Yes. Storm damage, active leaks, and emergency tarping are available 24/7. Call (206) 659-4349 immediately for emergency service.
