Roof Replacement Done Once, Done Right
Honest assessment before we quote, full system install (not just shingles), and warranties that transfer when you sell the home.
- Asphalt Shingle
- Standing Seam Metal
- Cedar Shake Conversion
- Full Re-Roof
How a Replacement Works
Three steps from quote to crew on the roof.
Free Inspection
We walk the roof, document with photos, check the attic for ventilation and decking, and give you an honest read on remaining life vs replacement.
Material Walkthrough
Shingle samples or metal panels brought to your home. You see the colors in your light, not in a showroom. Line-item written quote within 48 hours.
3 to 7 Day Install
Standard asphalt replacements run 3 to 5 days. Metal 5 to 8. Cedar conversions add 1 to 2 days for full deck replacement.
What We Replace
Asphalt Shingle Roofs
GAF Timberline HDZ, designer Grand Sequoia, and Class 4 impact-rated systems. 25 to 30 year real-world lifespan in PNW conditions with proper ventilation.
Standing Seam Metal
24-gauge Kynar 500 finish, concealed fastener, 50 to 70 year service life. Best for homeowners planning to stay 20 plus years.
Cedar Shake Conversion
Aging cedar shake gets removed and replaced with modern asphalt or metal. Deck almost always needs full plywood replacement since skip sheathing fails inspection.
Flat and Low-Slope Systems
TPO and modified bitumen for low-slope sections, additions, and modern architecture. Specialty install with seam-welded membranes.
Tear-Off and Deck Inspection
Old roof comes off completely. Deck inspected and any rot replaced at our published per-sheet rate before underlayment goes down.
Underlayment and Ice & Water
Synthetic underlayment plus ice and water shield at eaves, valleys, and around all penetrations. Code-plus, not code-minimum.
Ridge Ventilation Upgrade
Most pre-1995 King County homes are under-ventilated. We balance intake and exhaust as part of every replacement to extend shingle life.

Frequently Asked Questions
How long does a roof replacement take?
Most asphalt shingle replacements on King County homes take 3 to 5 working days on site. Metal runs 5 to 8 days because of panel forming. Cedar shake conversions take 5 to 7 days because deck replacement is almost always required. Total elapsed timeline from contract to final inspection is 2 to 5 weeks.
What does a roof replacement cost in King County?
Most architectural asphalt replacements run 14000 to 28000 dollars depending on home size, complexity, and material grade. Premium materials and metal push higher. We publish line-item quotes with no hidden change orders so you know what you are paying for.
Do you offer financing for roof replacement?
Yes. We partner with Wisetack for approved homeowners to split the cost over 12 to 60 months with no penalty for early payoff. Most applications get a decision in under 60 seconds with a soft credit check.
Is the warranty transferable when I sell the home?
Yes on manufacturer warranties (including GAF Golden Pledge if you choose that system) and yes on most of our workmanship warranty under the standard transfer terms. Transferable coverage adds documented resale value to the home.
Do I need a permit?
Almost always in King County. We pull the permit, handle the inspection scheduling, and only bill the final after the city signs off. Permit fees typically run 200 to 450 dollars depending on the municipality and project valuation.
Will my insurance cover the replacement?
Insurance covers documented sudden and accidental damage (wind, hail, fallen tree, impact). Age-related replacement is a homeowner expense. If a recent storm caused the damage, document immediately and we can support the claim with pre-adjuster photos and a written contractor scope.
Ready for a Roof That Lasts Two Decades?
Replace at the right time, with the right system, and the lifecycle math works out. Replace early or replace with the wrong system and you pay twice. We will inspect for free and tell you honestly which side of that line your roof is on.
