The Complete Guide to Garage Doors

Choosing the Right Garage Door for the Pacific Northwest

After twenty-plus years installing and servicing garage doors across the Puget Sound region, I can tell you that what works in Arizona does not work here. Our climate — persistent rain, high humidity, occasional windstorms off the coast, and temperature swings from the low 30s to the mid-80s — demands a door that can handle moisture without warping, rusting, or losing its seal.

This guide covers the major decisions every homeowner faces when shopping for a new garage door.

Garage Door Materials

Steel is the most popular choice in our area, and for good reason. Modern steel doors from Overhead Door — like their Traditional Steel and Thermacore collections — come with factory-applied finishes that resist corrosion. A quality steel door with polyurethane insulation will outperform wood in our wet climate with far less maintenance. Expect 20-30 years from a well-built steel door.Wood remains beautiful but demands commitment. Overhead Door's Traditional Wood collection uses rot-resistant species like western red cedar, but you are still looking at staining or painting every 2-3 years here in western Washington. Rain and moss will punish neglected wood doors quickly.Aluminum doors — like Overhead Door's Modern Aluminum collection — deliver a clean contemporary look with glass panels. They will not rust and are lighter weight, but they dent easier than steel and offer minimal insulation on their own. Great for detached shops or modern homes where aesthetics matter more than thermal performance.Fiberglass resists denting and does not rust, but it can yellow and become brittle over time with UV exposure. It is a niche choice, not a mainstream one.Vinyl is virtually maintenance-free and handles moisture well, but color and style options are limited compared to steel. Decent choice for rental properties or coastal homes where salt air is a factor.

Insulation: R-Values That Matter Here

Insulation is not optional in the Pacific Northwest — especially if your garage is attached to your living space. Here is the range:

• R-0: No insulation. Single-layer steel or aluminum. Fine for detached garages you do not heat.
• R-6 to R-9: Polystyrene insulation sandwiched between steel skins. Good baseline for attached garages.
• R-12 to R-13: Polyurethane injected between steel layers. This is our most recommended range for homes in the Tacoma-Seattle-Olympia corridor.
• R-17 to R-17.5: Premium insulation, like Overhead Door's Thermacore line. Best for bonus rooms above the garage, heated workshops, or homeowners who want the quietest, most energy-efficient door available.

Polyurethane insulation is denser and a better moisture barrier than polystyrene — a real advantage when your garage faces prevailing weather.

Sizing Your Garage Door

Standard residential sizes are 8x7, 9x7, and 16x7 feet (single and double). But many older homes in Tacoma, Lakewood, and Puyallup have non-standard openings — 8x6.5 or 18x8 are common enough that we keep those sizes in regular rotation. Always measure the rough opening width and height, plus the headroom and sideroom available for tracks and hardware.

Styles and Curb Appeal

Overhead Door's Courtyard Collection gives you the carriage-house look with modern steel performance — it is the best-selling premium style in our territory. For a cleaner look, the Traditional Steel line comes in flush, raised-panel, and long-panel designs with dozens of color and window options.

Wind Load for Coastal Washington

If you are near the coast — Ocean Shores, Westport, Long Beach — Washington state building codes require wind-load-rated garage doors. These doors have reinforced struts and heavier-gauge steel to withstand sustained winds. We install wind-rated doors that meet or exceed local code requirements. Even if you are inland, a wind-load-rated door adds rigidity and longevity.

How to Choose

Start with your budget and your garage's relationship to your home. Attached garage with a room above? Go Thermacore R-17. Detached shop? A Traditional Steel R-6 will do the job. Want curb appeal that turns heads? The Courtyard Collection. Talk to a local installer who knows the climate and building codes — not a big-box store associate reading a spec sheet.
