How Long Do Roofs Last in the Pacific Northwest?
How Long Do Roofs Last int the PNW
When it comes to protecting your home in the Pacific Northwest, your roof is your first line of defense. But with all the rain, moss, wind, and coastal storms our region is known for, many homeowners in Vancouver, WA, and across Oregon find themselves asking: “How long will my roof actually last here?”
At Rain City Roofers, we’ve seen how climate plays a huge role in roof performance. Below, we’ll break down the average lifespan of different roofing materials in our area, how local weather impacts them, and tips to extend your roof’s life.
Asphalt Shingles: 15–25 Years in the PNW
Asphalt shingles are a top choice for many Pacific Northwest homeowners because they balance affordability with reliable performance in rainy, windy, and moss-prone conditions. While shingles have traditionally been seen as a shorter-lifespan option compared to metal, modern technology has changed the game.
At Rain City Roofers, we install Owens Corning shingles, and as a Preferred Contractor, we’re able to provide homeowners with a 50-year non-prorated warranty. This means your investment is fully protected for decades without the fine print or gradual coverage reductions you see with other warranties.
With proper installation and maintenance, asphalt shingles can last 15–25 years in the PNW climate, but the non-prorated 50-year coverage gives you long-term security and confidence. For homeowners who want an attractive, cost-effective roof backed by one of the best warranties in the industry, shingles are a smart choice.
Metal Roofing: 50+ Years of Protection
If longevity is your priority, metal roofing is the clear winner in the Pacific Northwest. With proper installation and maintenance, metal roofs can last 50 years or more — sometimes even up to 70.
Why? They naturally shed rain, resist moss growth, and stand strong against high winds along the Oregon coast. Metal also doesn’t crack, curl, or absorb water like shingles, making it one of the most durable options in our region.

Cedar Shake & Tile Roofing: Niche but Durable
Some homeowners choose cedar shakes for a rustic look. In the PNW, cedar typically lasts 20–30 years with regular maintenance, but it is prone to moss and rot without proper care. Tile and slate, though less common here due to weight and cost, can last 40–50 years with professional installation.
Coastal Oregon Weather: A Roof’s Biggest Test
Homes near the beaches of Oregon face unique challenges:
- Salt air can corrode some metals if they’re not coated correctly.
- High winds during storms often tear shingles away.
- Constant moisture speeds up moss and algae growth.
For coastal homeowners, investing in durable materials like metal and scheduling regular roof inspections is critical to maximizing lifespan.
Tips to Extend the Life of Your Roof
No matter what type of roof you have, a little maintenance goes a long way in the PNW. Here are a few ways to keep your roof performing at its best:
- Remove moss and algae growth.
- Keep gutters clear of leaves and debris.
- Trim overhanging branches.
- Schedule annual roof inspections to catch small issues before they grow.
Signs Your Roof May Be at the End of Its Life
If your roof is nearing its expected lifespan, watch for these warning signs:
- Curling or cracked shingles
- Frequent leaks or water spots inside
- Excessive moss or algae growth
- Rust or loose panels on metal roofs
If you’re seeing these issues, it may be time to start planning for a replacement.
