We’ve been climbing roofs in this town since 2016. We know the difference between a Hollywood Hill estate lot buried under Douglas fir canopy and a sunny rambler down near the Sammamish River Valley. That local knowledge matters because Woodinville’s conditions destroy roofs differently than they do in Redmond or Kirkland. When you hire our Roof Replacement & Installation team, you get people who understand why your north-facing shingles are failing early - and what to do so it doesn’t happen again.

Woodinville homeowners call us because we’ve been here long enough to have replaced roofs twice on the same street.

Our 90-Day Done Right Promise means exactly what it says: if something isn’t right, we come back and make it right. No paperwork gauntlet, no voicemail runaround. Our phones are staffed by a live person 24 hours a day, including the middle of a storm, because we know a failing roof doesn’t wait for business hours.

Our Roof Replacement & Installation Services in Woodinville
Full Roof Replacement
Most Woodinville homes built between 1980 and 2005 are hitting their second roof cycle right now. The cedar shake roofs from that era are 25-40 years old and past end of life. We recently replaced a moss-damaged cedar shake roof on a custom home off Hollywood Hill Drive in 98077. The 30-year-old shakes were original to the 1990s build, and beneath them we found OSB decking blackened from years of moisture trapped by moss mats. We installed GAF Timberline UHD shingles with a zinc strip moss inhibitor - a must for this perpetually shaded hillside. Our full replacements include tear-off, deck inspection and repair, ice-and-water shield at valleys and eaves, and proper ventilation calculation for your specific roof geometry.
New Construction Roofing
Woodinville’s remaining buildable lots tend toward the hillside and estate-sized, which means complex rooflines and strict drainage planning. We work with local builders and homeowners from framing inspection through final walkthrough, specifying materials that match the microclimate. On wooded lots in 98072 and 98077, we specify synthetic underlayment and enhanced valley flashing as standard - not upgrades - because we’ve seen too many “standard” installations fail within a decade under canopy conditions.
Asphalt Shingle Installation
Asphalt shingles remain the practical choice for most Woodinville homes, but material selection here requires more thought than in sunnier suburbs. We install Owens Corning Duration and IKO Cambridge lines with StainGuard or similar algae-resistant granules, and we always specify zinc or copper ridge strips on north- and west-facing planes. The number on our estimate is the number on your invoice. A typical 2,500-square-foot composition re-roof in Woodinville runs $12,000-$18,000, including tear-off and standard deck repair.
Metal Roofing
Metal roofing performs exceptionally well in Woodinville’s wet climate when specified correctly. Standing-seam systems shed debris and moss better than shingle profiles, and their 50+ year lifespan makes sense for homeowners planning to stay put. We install Atlas and Tamko metal product lines, with proper fastening patterns for our wind-exposed hillside locations. Expect $22,000-$35,000 for a residential standing-seam installation, with significant variation based on roof complexity and access.
Tile Roofing
Concrete and clay tile suit the custom Mediterranean and Pacific Northwest contemporary homes scattered through Woodinville’s estate neighborhoods. These systems demand precise structural assessment - tile is heavy - and specialized underlayment that can handle decades of moisture cycling. We verify rafter capacity and specify appropriate battens or direct-deck installation based on your roof’s condition.
Flat Roofing
Winery-adjacent agricultural buildings, modern home additions, and some custom designs in Woodinville rely on low-slope systems. We install TPO, modified bitumen, and PVC membranes with proper drainage scuppers and tapered insulation where needed. Flat roofs under tree canopy require particular attention to debris management and seam integrity - we specify walkable membrane thicknesses and install leaf guards at drains as standard practice.

Common Roof Replacement & Installation Problems We See in Woodinville Homes
- Moss-trapped deck rot. On north-facing slopes in the Hollywood Hill area and along the forested ridgelines of 98077, we regularly pull back composition shingles installed as recently as 2005 and find the OSB decking blackened with moisture damage - caused not by storm events but by years of biological mat from moss holding standing moisture against the surface under near-permanent shade.
- Skipped moss inhibitors on re-roofs. DIY or low-bid contractors skip zinc strip or copper flashing installation, so moss recurs within two seasons on shaded north slopes. We see this constantly on homes where the previous roofer treated Woodinville like Bellevue.
- Valley failures on steep wooded lots. Improper flashing at valley intersections allows water to pool under canopy debris, accelerating fastener corrosion and shingle edge curling. The debris load here is heavier than most contractors account for.
- Flat roof ponding on agricultural structures. Winery and farm buildings in the Sammamish Valley often have original flat roofs with inadequate slope or clogged drainage. We address the underlying geometry, not just the membrane.

FAQs - Roof Replacement & Installation in Woodinville
Woodinville’s dense conifer canopy - especially on hillside estate lots in 98077 - keeps north- and west-facing roof planes damp from October through May, accelerating moss colonization and deck rot. Roofs here typically need replacement 5-10 years sooner than comparable materials in sunnier Redmond or Kirkland. We specify moss-resistant materials and zinc inhibitors as standard for these properties, not upgrades. Call (866) 850-9676 for a free inspection - we’ll show you exactly what your roof faces.
Most Woodinville homeowners with original cedar shakes are moving to high-grade composition shingles for lower maintenance and better moss resistance. Real cedar requires treatment every 2-3 years in this climate, and many insurers now surcharge or exclude cedar roofs. We install GAF and Owens Corning architectural lines that replicate cedar’s dimensional look without the upkeep. If you prefer genuine cedar, we source Alaskan Yellow Cedar or treated Western Red Cedar with proper ventilation - but we’ll be direct about the maintenance commitment. Call for samples and an honest comparison.
You cannot tell from the ground. The only reliable method is a hands-on inspection with deck probing during tear-off, or thermal imaging and moisture meter readings from the attic side. We document deck condition with photos during every inspection. If you’re seeing ceiling stains, sagging ridgelines, or nails popping through shingles, suspect deck damage. Schedule a free inspection at (866) 850-9676 - we’ll show you what we find, no obligation.
These structures need positive drainage (no ponding), debris-resistant membrane colors, and robust flashing at equipment penetrations. The Sammamish Valley’s leaf and pollen load is substantial, so we oversize drains and install leaf guards. We also assess whether the existing structure can handle modern insulation requirements if the building is being converted to conditioned space. Agricultural flat roofs are a specialty - call us for an evaluation specific to your building’s use and condition.
Yes, when specified correctly. Standing-seam metal sheds moss and debris better than any shingle product, and its lifespan matches the ownership horizon of most Woodinville estate homeowners. The key is proper underlayment (synthetic, not felt) and appropriate fastener gaskets for our wet climate. We avoid exposed-fastener panels on residential work - the screw penetrations become maintenance items. Expect $22,000-$35,000 installed. Call (866) 850-9676 for a detailed quote and material samples.
