We’ve worked Union Hill-Novelty Hill roofs since the first custom homes went up in the 1990s. We know the Sammamish Plateau’s wet micro-climate, the dense fir canopy that keeps roofs damp, and the complex rooflines that builders favored during the tech boom. That local knowledge matters when you’re deciding whether a leak needs a patch or a larger fix, and it matters when permits run through King County DPER instead of city offices most contractors are used to dealing with.

Our Roof Repair Services in Union Hill-Novelty Hill
Leak Repair
Leaks in Union Hill-Novelty Hill homes often trace back to two sources: undersized ice and water shield in 1990s-era valleys, and moss infiltration under cedar shingles on north-facing slopes that never fully dry beneath the fir canopy. We track the water path methodically, repair the source, and document the fix with photos. Typical leak repair in Union Hill-Novelty Hill runs $350-$750 depending on access and how far the water traveled before showing inside.

Flashing Repair
Complex rooflines with multiple dormers and steep pitches, common in plateau custom homes, create dozens of flashing junctions that expand and contract through wet seasons. King County DPER requires separate inspections for flashing work on repairs exceeding certain thresholds, a detail that catches metro contractors who assume Sammamish or Redmond rules apply. We handle the permit routing and know the inspector schedules. Flashing repair typically runs $300-$650.

Shingle Replacement
We replaced wind-damaged shingles on a sprawling custom home off 238th Ave SE that had GAF Timberline HDZ from the original 2005 build. The complex roofline with multiple dormers and steep pitches required full fall protection rigging, and the King County DPER permit added a week to the timeline compared to city permits. We stock Owens Corning, IKO, and Atlas shingles for fast color matching on Union Hill-Novelty Hill’s common 2000s-era palettes. Shingle replacement runs $250-$600 per damaged area.

Flat Roof Patch
Low-slope sections on custom homes, often over bays or porches, collect debris from the dense canopy and hold moisture longer than pitched sections. We use manufacturer-authorized membranes and sealants, not generic products, and we inspect the underlying deck for soft spots before sealing. Flat roof patches in Union Hill-Novelty Hill typically run $400-$900.

Trusted Brands We Service in Union Hill-Novelty Hill
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Union Hill-Novelty Hill homeowners, that means we stock parts that match the original 1990s-2010s installations common on the plateau. No substitutions, no waiting for a distributor run to Auburn. When a storm tears through and you need matching shingles for a repair, we can often pull from our Seattle inventory and get the color right the first time. That matters on a custom home where the roofline is visible from the approach and mismatched patches show.
Common Roof Repair Problems We See in Union Hill-Novelty Hill Homes
- Valley leaks from insufficient ice and water shield. Many 1990s custom builds used standard underlayment in valleys where code now requires full ice and water shield. During plateau downpours, water backs up and finds its way in. We see this repeatedly in homes near the 238th Ave SE corridor.
- Moss and lichen accelerating shingle decay. The combination of higher elevation rainfall and dense Douglas fir canopy keeps north-facing slopes damp year-round. Moss works under shingle edges, lifting and rotting before the rated lifespan expires. Cedar shake roofs are especially vulnerable.
- Permit delays from assuming city rules apply. Union Hill-Novelty Hill is unincorporated King County, so all roofing permits and inspections run through King County Permitting and Environmental Review, not Sammamish or Redmond. Contractors who primarily work incorporated Eastside cities routinely underestimate timeline and paperwork differences.
- Granule loss on aging composition shingles. The 1990s-2010s building wave means a large cohort of roofs carries original 25-30 year shingles now at or past rated life. The plateau’s wet micro-climate shortens effective lifespan further. We inspect for exposed fiberglass mat and UV damage that precedes leaks.

FAQs - Roof Repair in Union Hill-Novelty Hill
Yes. Union Hill-Novelty Hill is unincorporated King County, so all roofing permits run through King County DPER, not Sammamish or Redmond city offices. The fee schedule, online submittal portal, and inspector availability differ from incorporated cities, and flashing work may require its own inspection. We handle the routing and know the timelines. Call (866) 850-9676 and we’ll walk you through what your specific job requires.
The Sammamish Plateau receives more annual rainfall than lower Eastside areas, and the dense Douglas fir and western red cedar canopy blocks sun and airflow that would otherwise dry your roof between storms. North-facing slopes stay damp enough for moss, lichen, and algae to colonize aggressively, often degrading shingles faster than rated lifespans predict. Regular maintenance helps, but the environmental pressure is real. Our $89 Seasonal Tune-Up includes moss treatment and gutter clearing.
Complex rooflines with multiple planes, dormers, and steep pitches create more flashing junctions than simpler designs, and each junction is a potential failure point during heavy plateau rain. We use manufacturer-specified materials and techniques, and on larger repairs, King County DPER may require separate flashing inspections. Our field team has worked these rooflines since the first custom homes went up in the 1990s.
Given the wet micro-climate and dense canopy, we recommend a professional inspection every two years for Union Hill-Novelty Hill homes, and annually once your roof passes 20 years of age. The 1990s-2010s building wave means many original roofs are at or past rated life now. Our inspections are photo-documented from your actual roof, not the driveway. Call for our $89 Seasonal Tune-Up or a free repair estimate.
Yes. We repair and replace cedar shakes on steep-pitch custom homes throughout Union Hill-Novelty Hill, using proper fall protection and matching species and exposure to existing courses. Cedar requires different fastening and ventilation knowledge than composition shingles, and our journeymen are trained for both. Most cedar shake repairs run $400-$950 depending on access and how many shakes need replacement. Call (866) 850-9676 for an exact quote - estimates are free.
