Picking a roofing material in the Pacific Northwest isn't the same decision as it is in Texas or Florida. Our problems are different. We don't get much hail. We don't get hurricanes. What we get is eight months of moisture, aggressive moss, 40 mph gusts off the Sound, and the occasional wet snow that sits on a roof for three days. The material you pick has to handle all of that, and it has to do it for decades without constant babysitting.
We've installed every type listed below on homes across Seattle, Bellevue, Kirkland, and south through Tacoma. Here's how they actually rank for this climate, with real 2026 installed pricing from our own quotes.
## 1. Architectural shingles (the default, and for good reason)
**What it is:** A thicker, layered asphalt shingle with a dimensional look. GAF Timberline, Owens Corning Duration, and CertainTeed Landmark are the three lines we install most.
**Cost installed:** $7 to $9 per square foot. A typical 2,000 sq ft Seattle roof runs $14,000 to $22,000 for a full tear-off and replacement. Our 2026 cost breakdown has more detail on what drives that range.
**Lifespan:** 25 to 30 years with proper maintenance in the PNW. Longer in sunnier climates, but moss and moisture shave a few years off here.
**PNW performance:** Handles rain well. The layered design gives it better wind resistance than 3-tab (rated to 130 mph on most lines). Moss is the main enemy. North slopes under tree canopy will grow moss faster, but regular cleaning keeps it in check. Algae-resistant versions with copper granules help slow the growth.
**Pros:** Best value for the money, wide color selection, most crews install it well, 30 to 50 year manufacturer warranties. **Cons:** Moss-prone without maintenance, can lose granules under heavy foot traffic, and the 25-year reality in the PNW doesn't match the 50-year warranty printed on the box.
This is what we put on about 80% of the homes we roof. For a deeper look at why we almost always recommend architectural over the cheaper option, read our architectural vs. 3-tab comparison. If you're ready for numbers on your specific house, the roof cost estimator gives you a ballpark in under a minute.
## 2. Standing seam metal
**What it is:** Interlocking metal panels with raised seams, no exposed fasteners. Usually steel or aluminum with a baked-on finish.
**Cost installed:** $12 to $18 per square foot. That same 2,000 sq ft roof is now $24,000 to $36,000. Complex rooflines with lots of hips, valleys, and penetrations push toward the high end.
**Lifespan:** 40 to 60 years. The panels outlast the paint finish by a wide margin.
**PNW performance:** Rain sheds off a metal roof like nothing else. The smooth surface resists moss better than any shingle, though shaded north slopes still get some growth. Wind ratings are strong. Noise is a non-issue with proper decking and underlayment underneath.
**Pros:** Longest lifespan of any residential option, lowest moss adhesion, great for steep or complex roofs where water speed matters, looks sharp on modern and craftsman builds. **Cons:** Roughly double the cost of architectural shingles, fewer crews install it correctly, and some HOAs in Sammamish and Redmond still push back on it. We covered the full comparison in our metal roof vs. shingles breakdown.
**Best overall if budget allows.** If you're staying in the house long-term and want a roof that outlasts the mortgage, standing seam is it. For commercial buildings with low-slope sections, metal is often the smartest play.
## 3. 3-tab shingles
**What it is:** The original flat asphalt shingle. Single layer, uniform look, lighter weight than architectural.
**Cost installed:** $5 to $7 per square foot. The budget option, and it shows.
**Lifespan:** 15 to 20 years in the PNW. The rated 25-year warranty rarely plays out here because the thinner profile wears faster under constant moisture.
**PNW performance:** Adequate rain shedding, but the flat profile catches wind worse than architectural. In a 50 mph gust, 3-tab lifts and tears where architectural stays down. Moss is just as aggressive as on any asphalt product.
**Pros:** Cheapest installed cost, fine for rental properties, detached garages, or a house you're selling soon. **Cons:** Shorter real-world lifespan, weaker wind resistance, looks dated compared to dimensional shingles, and the cost difference per square foot is small enough that we rarely recommend it for a primary home.
**When it still makes sense:** Investment properties where you need a functional roof at the lowest price, or a small outbuilding where the aesthetics don't matter. For your own house, spend the extra dollar per square foot and get architectural. Our shingle installation page has more on what we offer.
## 4. Synthetic slate and composite
**What it is:** Engineered materials (usually polymer or rubber-based) molded to look like natural slate or shake. DaVinci and Brava are the brands we see most.
**Cost installed:** $10 to $15 per square foot. Lands between architectural shingles and standing seam.
**Lifespan:** 30 to 50 years based on manufacturer claims. The products haven't been around long enough in the PNW for us to confirm that from experience, but early returns are solid.
**PNW performance:** Good rain shedding, Class A fire rating, and better moss resistance than asphalt due to the smoother surface texture. Holds up well in wind. The weight is lighter than real slate, so no structural upgrades needed.
**Pros:** High-end look without the weight or cost of real slate, strong fire rating (relevant for WUI zones around Issaquah and the Sammamish Plateau), long warranty. **Cons:** Limited installer base in Seattle, fewer real-world track records in this climate, and the per-foot cost pushes it into metal territory where metal has a proven 50-year record here.
Worth considering if you want the slate aesthetic on a home that can't handle real slate weight.
## 5. Cedar shake
**What it is:** Split or sawn western red cedar, the classic PNW roofing material. You see it on everything from 1940s Ballard bungalows to 1980s Eastside colonials.
**Cost installed:** $10 to $14 per square foot. More than shingles, less than metal, and the maintenance costs add up.
**Lifespan:** 20 to 25 years if maintained. Closer to 15 if it's not.
**PNW performance:** Cedar is beautiful and it handled PNW weather fine for decades. The problem is that it requires active maintenance (cleaning, treating, recoating) or it cups, splits, and rots. Moss loves cedar because the grain texture gives it something to grip. Fire rating is Class C unless treated, which is a real issue in wildfire-risk zones around Issaquah and east Sammamish.
**Pros:** Classic PNW look, natural material, good insulation value. **Cons:** High maintenance cost over time, fire risk, shorter lifespan than modern alternatives, and increasingly expensive as old-growth cedar supply tightens.
Cedar is declining for good reason. Most homeowners replacing an old cedar roof today switch to architectural shingles or synthetic shake rather than putting new cedar back on. We still install it when the homeowner wants to preserve the original look, but we're honest about the trade-offs.
## 6. TPO/PVC membrane (flat and low-slope roofs)
**What it is:** Single-ply membrane systems heat-welded at the seams. TPO (white) and PVC are the standard for flat and low-slope commercial and residential sections.
**Cost installed:** $8 to $12 per square foot. Pricing depends on access, penetration count, and insulation requirements.
**Lifespan:** 20 to 30 years for quality TPO. PVC runs a bit longer.
**PNW performance:** Great for flat roofs because the welded seams don't rely on gravity to shed water. Standing water is the enemy of shingles, but membrane handles ponding fine as long as drainage is working. Our PNW rain is steady but not torrential, which is actually a decent climate for these systems.
**Pros:** Only real option for flat and low-slope sections, fully welded seams, reflective surface reduces cooling costs, proven track record on commercial roofing projects across the region. **Cons:** Can't be used on steep slopes, requires specialized installation, and puncture damage from foot traffic or debris needs prompt repair.
If your home has a flat section (a lot of mid-century Seattle ramblers do), TPO or PVC is the right call for that portion, with shingles or metal on the sloped sections.
## The verdict
**Best value:** Architectural shingles. They hit the sweet spot of cost, lifespan, and performance for 80% of PNW homes. Get them installed right, keep the moss off, and you'll get a solid 25 to 30 years.
**Best overall (if budget allows):** Standing seam metal. Double the upfront cost, but it lasts twice as long, sheds moss better, and handles PNW wind and rain like it was built for it. Because it kind of was.
