How to Select the Right Roof Material

Choosing the right roofing material is one of the most important decisions a homeowner can make—especially in a climate as wet, windy, and unpredictable as Oregon’s. With long rainy seasons, heavy winter moisture, coastal winds, and occasional summer heatwaves, your roofing material must stand up to year-round weather challenges. Two of the most common residential roofing materials in Oregon are metal roofs and asphalt shingle roofs, each offering unique benefits and performance characteristics.

How Oregon’s Climate Impacts Roofing Materials

Oregon’s environment isn’t always gentle on roofs. Between the consistent rainfall in western Oregon, the humidity of the Willamette Valley, and the occasional storms that blow in from the coast, roofing materials must be resilient.

Key factors affecting roof performance include:

  • Long-term moisture exposure
  • Moss, algae, and mildew growth
  • Wind-driven rain
  • Temperature swings from cool winters to hot summer days
  • Occasional snow and ice in higher elevations

Both metal and asphalt can perform well in Oregon’s climate—but each material reacts differently to moisture, temperature, and wear.


Metal Roofs: Performance & Benefits in Oregon Weather

Metal roofing has grown in popularity in recent years thanks to its longevity, durability, and moisture resistance.

Exceptional Durability

Metal roofs can last 40–70 years or more, making them one of the longest-lasting roofing materials available. They resist rot, cracking, and warping—perfect for damp environments.

Superior Moisture Protection

Metal roofing systems shed water quickly and are less prone to leaks caused by moss growth or standing moisture. This makes them ideal for Oregon’s wet climate.

Wind Resistance

Metal roofs can withstand strong coastal winds and storm conditions better than most asphalt shingle systems.

Energy Efficiency

Metal reflects heat, helping stabilize indoor temperatures during Oregon summers and lowering cooling costs.

Low Maintenance

Metal roofs require far less frequent cleaning and maintenance than asphalt shingles, though they should still be inspected annually.

HER Roofing installs premium metal roofing systems built for durability and long-lasting protection in Oregon’s moisture-heavy weather.


Asphalt Shingle Roofs: Performance & Benefits in Oregon Weather

Asphalt shingles remain the most common and affordable roofing material for Portland and surrounding areas.

Cost-Effective Installation

Asphalt shingles are budget-friendly and offer good value for homeowners wanting reliable performance at a lower upfront cost.

Wide Range of Styles

Architectural shingles mimic the appearance of wood or slate and can complement any home style—especially older homes and traditional neighborhoods.

Good Performance in Rain

High-quality asphalt shingles are designed to resist wind-driven rain and provide solid weather protection when properly installed.

Moss & Algae Susceptibility

Asphalt shingles are more vulnerable to moss and algae, which thrive in Oregon’s damp climate. Regular roof cleaning is required to prevent premature wear.

Moderate Lifespan

Most asphalt roofs last 20–30 years, but lifespan can be shorter if moss or moisture damage goes untreated.

HER Roofing uses industry-leading asphalt shingle products with enhanced moisture resistance to maximize roof longevity in the Pacific Northwest.


Metal vs. Asphalt: Which Performs Best in Oregon?

Durability

Metal wins. It withstands rain, wind, and weather extremes significantly longer.

Moisture Resistance

Metal wins. It sheds water quickly and is less prone to moss growth.

Cost

Asphalt wins. Lower upfront cost makes it accessible for many homeowners.

Maintenance

Metal wins. Less moss, less cleaning, fewer repairs.

Aesthetic Flexibility

Tie. Asphalt offers classic curb appeal; metal offers sleek, contemporary looks.

Energy Efficiency

Metal wins. Reflective properties can lower cooling costs.

Ultimately, your choice depends on budget, long-term goals, and the architectural style of your home. Both materials can perform beautifully in Oregon when installed by an experienced local roofing contractor.


Choose the Right Roofing Material for Oregon Weather

Whether you choose metal or asphalt shingles, selecting the right roofing material ensures your home stays protected through Oregon’s rainy winters, windy storms, and warm summers. Understanding the differences between metal and asphalt helps you make a confident, informed decision that fits both your home and your budget.

Frequently Asked Questions About Metal vs. Asphalt Roofs

Do Metal Roofs Rust in Oregon’s Wet Climate?
Modern metal roofs use rust-resistant coatings and finishes, making rust extremely unlikely with proper installation.
Will Moss Grow on a Metal Roof?
Rarely. Moss doesn’t grow well on metal because it lacks porous surfaces and retains minimal moisture.
Are Asphalt Shingles Still a Good Choice in Rainy Climates?
Yes—especially when paired with proper attic ventilation and regular moss prevention treatments.
