Siding, Roofing, Windows & Decks in Olympia, WA

The median home in Olympia was built in 1982, but that middle number hides a wide spread: the housing stock runs from prewar houses to homes built since 2000 in close to equal shares. That spread is the first thing we look at, because a home’s age says a lot about what is on its walls, roof and window frames today. Builders Service Company is an exterior contractor handling siding, roofing, window and deck replacement for homeowners here and across Thurston County. The sections below cover what is typical for local homes, which materials suit them, and what each service involves.

Homes in Olympia: what’s on them now

Census data shows a housing stock split across four building eras. About 18% of homes date from before 1950, 29% from 1950 to 1979, 28% from 1980 to 1999 and 25% from 2000 or later. With no single era far ahead of the others, exterior needs can change from one block to the next.

Each era points to different materials on the house today:

• Before 1950: likely original wood lap siding, single-pane or early windows, and possible lead paint under older coats.
• 1950 to 1979: cedar, T1-11 or asbestos-cement shingle siding, with aluminum or early vinyl windows.
• 1980 to 1999: composite and hardboard siding, including LP siding, which has a known history of moisture failure, along with first-generation vinyl windows.
• 2000 or later: fiber cement or builder-grade vinyl siding reaching its first repaint or replacement, and builder-grade windows.

The structure mix shapes the work as well. Detached houses make up 52% of housing units, attached homes 14%, apartments 31% and mobile homes 2%. A detached house exposes all four walls and a full roof to the weather, while an attached home shares at least one wall with its neighbor, which changes the scope of a siding or roofing job.

The City of Olympia is the permit authority for exterior projects inside city limits.

Siding in Olympia

Roughly 29% of Olympia homes were built between 1950 and 1979, the era of cedar, T1-11 and asbestos-cement shingle siding. If your home has asbestos-cement shingles, they may contain asbestos and should be tested before removal.

We usually recommend three siding types, and none of them is wood:

• Vinyl siding is the most versatile and least expensive option, with a wide selection of colors. It suits large wall areas and tighter budgets.
• Evergreen Shield Siding System is our exclusive insulated composite siding, designed for the Pacific Northwest climate. Census data shows 61% of local homes heat with electricity. Its insulating graphite membrane gives a thermal resistance of R-2.0, compared with R-0.61 for standard vinyl siding, and that difference matters more where heating is costly.
• Metal siding is the other premium option we often suggest.

Stacked stone and stone veneer can be added as accents on wainscots, entries, columns or chimneys, alongside any of the three.

The median home value here is about $485,000, roughly 6% above the Thurston County median. Owners of homes in that range more often choose premium materials such as the Evergreen Shield Siding System or metal, though vinyl remains a strong fit for many houses. We discuss the best option for your home, and help you pick colors, during the free in-home consultation.

In 2026 we completed an Olympia siding replacement and exterior update on a home whose original siding had a dated yellow and brown color scheme the owners wanted to modernize and refresh.

Roofing in Olympia

Olympia sits in the South Sound, where rain runs heavier than in the central Puget Sound and moss on roofs is common. Moss holds moisture against the roof surface and at the edges, so a replacement here pays close attention to ventilation, underlayment, flashing and the gutters along the roof edge.

We install two main roof types and give them equal weight:

• Asphalt shingle roofing, a familiar fit for most pitched roofs.
• EDCO metal roofing, the metal system we install for owners who want a different look and material.

Older cedar shake roofs in wet areas tend to collect moss and rot, which is why we replace them with asphalt or metal rather than more wood.

Our roofing work covers full replacement of aging or damaged roofs and repairs that address leaks, wear and storm damage. On every job, we focus on proper sealing and ventilation so the roof can dry out between storms.

Mobile homes account for about 2% of local housing. Manufactured homes often have low-slope roofs that need a different approach than a standard pitched roof, and we check that during the consultation.

Wildfire risk here is rated low, at the 54th percentile statewide, so roof choices in this area are driven mainly by rain and moss rather than fire exposure.

Windows in Olympia

About 18% of Olympia homes were built before 1950, and houses from that era are likely to have single-pane or early windows. Another 28% date from 1980 to 1999, when first-generation vinyl windows were standard, and their seals may now be failing. We replace both with Preservation 9000 vinyl replacement windows. Builders Service Company is the exclusive provider of Preservation 9000 windows in Washington.

Heating cost is the other reason to look at windows here. Census data shows 61% of local homes heat with electricity, and where heating is costly, efficient windows have a larger payback. New windows can also mean fewer drafts and steadier indoor temperatures. Electric service comes from PSE, so check with PSE for current rebate programs.

Preservation 9000 windows come in double-hung, slider, casement, awning, hopper, picture, garden, bay and bow styles, plus custom shapes. A few ways to match styles to your rooms:

• Upper floors and tight eaves: sliders or casements.
• Kitchens and baths: casement, awning or hopper windows for ventilation.
• Rooms with a view: picture windows, or a bay or bow.
• Older homes: double-hung profiles that keep the original look.

During the free in-home consultation, we measure each opening and talk through which styles fit your home.

Decks in Olympia

A deck in the South Sound spends much of the year wet. Rain here runs heavier than in the central Puget Sound, and moss and rot are the main threats to an outdoor surface. That makes slip resistance, drainage and rot-resistant materials the first things to plan around.

We build with three decking materials:

• Composite decking does not rot and does not need staining.
• Vinyl decking also avoids rot and staining.
• Wood decking gives a natural look and works for tighter budgets, with regular sealing to keep moisture out.

Wildfire risk is rated low, at the 54th percentile statewide, so the choice here comes down mainly to moisture, upkeep and look.

A well-built deck adds usable space and works as an extension of your home for relaxing and entertaining. We design each deck to fit the house and the yard, and we go over materials, layout and drainage during the free in-home consultation.
