Corvallis sits at the western edge of the Willamette Valley where the foothills of the Coast Range begin. This geographic position means it catches the tail end of many Pacific weather systems as they cross the mountains — and those systems bring persistent, soaking rain from fall through early summer. While Corvallis doesn't get the wind or salt spray of the coast, it absolutely gets the moisture, and that moisture is the primary enemy of every roof in town.
The city's housing stock is diverse. Near the OSU campus, you'll find older homes from the 1920s through 1960s — many with original or aging roofing that's long overdue for replacement. The neighborhoods of Timberhill and North Corvallis feature newer construction shaded by tall Douglas fir and big-leaf maple canopy that creates ideal conditions for moss and algae growth. South Corvallis and the Philomath corridor have a mix of suburban development and rural properties, each with their own roofing challenges.
Tru-North Construction is just one hour away via Highway 20. We've built our reputation on managing moisture — it's what we do every day on the Oregon Coast. That expertise translates directly to Corvallis, where the same fundamental enemy (water) attacks roofs through different vectors: pooling on flat sections, wicking under moss-lifted shingles, and saturating valleys that weren't properly sealed.
