Sexton Mountain sits on rising ground west of Murray Boulevard, where rows of 1980s split-level and two-story homes face the full force of Washington County’s mild but steady winter rains. Water finds every seam on aging asphalt shingles, especially at valleys and around skylights that were standard when these subdivisions were built. Beaverton Roof & Leak Pros responds from our Beaverton base to stop leaks before they reach living spaces or finished basements common on the downhill sides of these streets.
Driveways along SW Sexton Mountain Drive and SW 155th often sit at angles that make ladder placement and debris removal slower than flat-street jobs. We stage materials on the uphill side and use roof jacks to keep footing secure during the long wet season. Dry summers let us schedule permanent fixes without weather delays, but most Sexton Mountain calls arrive between November and March when standing water on low-slope sections turns small flashing failures into active leaks.
Proximity to Fanno Creek means some lots sit near seasonal drainage paths that can back up against foundation walls during heavy rain. We check both roof and upper wall flashing on every service visit so water is directed away before it reaches crawl spaces typical in this neighborhood.

Roof Leak Repair in Sexton Mountain, OR — Local Notes
- •Many Sexton Mountain roofs from the 1980s use 20-year shingles now past life, with valley leaks showing first on the north-facing slopes that stay wet longest.
- •Narrow driveways and steep side yards require extra time to stage tarps and ladders safely on the uphill side of each property.
- •Prolonged winter rain can push water under step flashing where decks meet the house, a common detail on the split-level homes along SW Sexton Mountain Drive.
- •Homes backing to Fanno Creek greenway see extra debris from trees that hold moisture against the roof longer than open lots.
