Serving Hillsboro and Greater Portland
Hillsboro has grown quickly as part of the broader Portland-area suburban expansion, with a mix of homes ranging from older established neighborhoods around the historic downtown to newer construction in South Hillsboro.
Pacific Exteriors serves communities across Washington County. We bring certified installation crews and manufacturer-backed warranties to every project, and we're licensed to work in Oregon.
Roofing Installation in Hillsboro, OR
We replace roofing systems that have reached the end of their useful life. Typically 20 to 30 years for standard asphalt shingles, shorter when ventilation was poor or weather exposure was significant.
Hillsboro and the rest of Washington County get consistent rainfall from fall through spring, and roofing systems here work harder than in drier climates. We install architectural shingles from leading manufacturers like Owens Corning, install proper underlayment, and ice-and-water shield where needed.
Our roofing page covers materials and process in more detail. Use our roofing cost calculator for a ballpark before scheduling an estimate.
How Much Does Siding or Roofing Cost in Hillsboro?
In the greater Portland area, siding replacement typically runs from around $25,000 for smaller homes to $45,000 or more for larger two-story projects. Roofing replacement generally falls between $7,000 to $20,000 for most residential homes. See our pricing page for more context, or get a rough quote online.
The main cost variables:
House Size and Height
Square footage and height affect both material quantity and labor time.
Material Choice
Fiber cement runs more upfront than some materials but outperforms it over time.
Roof Complexity
Steeper pitches, valleys, and dormers require more time and planning.
Putting Off Repairs Means Costly Damage
With about 39 inches of annual rainfall and rain on roughly 156 days a year, even small failures in an exterior system compound quickly. A failed caulk joint or a hairline crack in siding isn't just cosmetic — water migrates behind the surface, saturates sheathing, and begins breaking down framing. By the time damage becomes visible inside, the scope has almost always grown beyond what the original repair would have cost.
Signs Your Siding Needs Replacing
Two or more of these together is a signal to get an assessment, not another coat of paint.
Visible Damage
Boards warped, buckled, or pulling away from the wall.
Peeling Paint
Paint that fails within one to two years of application.
Soft Spots
Soft spots when you press on the siding surface.
Gaps at Seams
Failed caulk at seams, corners, or around window frames

Choosing the Right Exterior for Hillsboro's Weather
Hillsboro sits in the mild, wet climate of the Tualatin Valley on the western side of the Portland metro area. Winters are cool and wet, with January lows averaging around 37°F and occasional snow and ice events. Summers are warm and dry, with July highs averaging around 81°F. Most of the year's rain falls between October and March. Annual rainfall totals about 39 inches, spread across roughly 156 wet days a year with December being the wettest month.
Hillsboro sees about 32 nights a year below freezing. The consistent failure pattern for older exterior systems here is wood that absorbs moisture and rots at the base and around trim, vinyl that gaps at seams and lets water in behind the panels, and asphalt roofing that grows moss and degrades faster than rated when shade is heavy or attic ventilation is inadequate.
Fiber cement handles the moisture, freeze-thaw, and dimensional stability challenges that cause those failures.
