Serving Mercer Island and Greater Seattle
Mercer Island has grown steadily since the first floating bridge connected it to Seattle in 1940, with a mix of homes ranging from older established neighborhoods in East Seattle and First Hill to newer construction across the island.
Pacific Exteriors serves communities across King County. We bring certified installation crews and manufacturer-backed warranties to every project, and we're licensed to work in Washington.
Roofing Installation in Mercer Island, WA
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.
Mercer Island and the surrounding Eastside 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 Mercer Island?
In the greater Seattle 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 153 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 Mercer Island's Weather
Mercer Island sits in the mild, wet marine climate that covers most of the Puget Sound area. Winters are cool and wet: January lows average around 37°F with occasional snow and ice events. Summers are mild and dry: July highs average around 76°F, and most of the year's rain falls between October and May. Annual rainfall totals about 39 inches, spread across roughly 153 wet days a year with November being the wettest month.
Mercer Island shares these climate characteristics with the rest of the Eastside, with some added moisture exposure from its position in the middle of Lake Washington and the island's heavily treed neighborhoods. The consistent failure pattern for older exterior systems here: wood absorbs moisture and rots at the base and around trim; vinyl gaps at seams and lets water in behind the panels; asphalt roofing 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.
