Choosing the Right Roofing Material for the Pacific Northwest

Spring in Washington isn’t just about blooming flowers and longer days—it’s also a time when many homeowners and business owners start planning improvement projects. For properties with aging or worn roofing systems, spring is the perfect season to choose and install a new roof before summer heat and autumn rains arrive.

At EDCA Roofing, we’ve been installing high-quality roofing systems across the Puget Sound since 1988. We know that the Pacific Northwest’s unique mix of heavy rain, occasional snow, windstorms, and mild summers calls for roofing materials that are as durable as they are attractive. Here’s our updated 2025 guide to the best options for homes and businesses in our region.

Factors to Consider in Washington’s Climate

When selecting a new roofing material, it’s important to prioritize:

• Water Resistance – The ability to shed heavy rain and prevent leaks.
• Wind Resistance – Protection against gusts from seasonal storms.
• Moss and Algae Resistance – Critical in our damp climate.
• Energy Efficiency – Reflective properties that help regulate indoor temperatures.
• Longevity – Materials that can handle decades of Pacific Northwest weather.

Top Roofing Materials for the Pacific Northwest

1. Composition Shingles for Steep-Slope Roofs

A top choice for Washington homeowners, composition shingles combine versatility, durability, and visual appeal.

• Durability: Can last 20–25 years with proper installation and care.
• Weather Resistance: Designed to withstand wind, rain, and occasional snow.
• Aesthetic Options: Wide range of colors and textures to complement any architecture.
• Brands We Trust: GAF, CertainTeed, Pabco, and Owens Corning for proven performance and warranties.

2. TPO and PVC Single-Ply Systems for Low-Slope Roofs

Ideal for both residential and commercial flat or low-slope applications, these materials deliver outstanding waterproofing.

• Durability: Resistant to tears, punctures, and UV degradation.
• Energy Efficiency: Highly reflective surfaces reduce heat absorption, lowering cooling costs.
• Low Maintenance: Minimal upkeep needed, even in high-moisture areas.
• Best Use Cases: Commercial buildings, modern residential designs with flat roof sections.

3. Torch Down Roofing for Low-Slope Applications

Torch-down roofing uses modified bitumen, creating a seamless, watertight barrier.

• Weather Protection: Exceptional resistance to ponding water and leaks.
• Longevity: Withstands decades of seasonal changes when installed correctly.
• Ideal For: Low-slope roofs exposed to heavy rain or snow.

Matching Material to Your Property Type

• Residential Homes: Composition shingles remain the most popular for steep-slope roofs, with TPO or PVC for flat sections.
• Commercial Properties: TPO, PVC, or torch-down systems offer excellent durability, energy efficiency, and low maintenance.
• Multi-Family Housing: Combination systems—composition for pitched areas, TPO or PVC for flat portions—deliver both function and curb appeal.

Why Spring Is the Best Time to Choose and Install

Replacing your roof in spring offers several advantages:

• Mild Weather for Installation – Ideal temperatures help materials perform their best during installation.
