- Elevating Exteriors – From Concept to Completion
Anacortes sits at the edge of the Salish Sea, which means its homes deal with a specific mix of roofing stress that inland Washington towns don't: near-constant winter rain, salt-tinged air drifting off Guemes Channel and Rosario Strait, and wind that funnels across the Skagit flats before hitting the bluffs. Move a few miles inland toward Mount Vernon, Burlington or Sedro-Woolley and the salt exposure fades but the rain and moss pressure stay, with a bit more chance of foothill snow and ice in a cold snap. Picking a roof for this area isn't about finding the single best product on paper — it's about matching a material to what your specific lot, tree cover and exposure actually throw at it. This guide walks through how we weigh the options and where each one earns its keep.
For most Anacortes and Skagit County homes, a well-installed architectural (dimensional) asphalt shingle roof or a standing seam metal roof are the two safest bets, and the right one depends on your roofline, your budget and how long you plan to own the house. Asphalt shingles remain the practical middle ground: reasonably priced, widely serviceable, and available in wind-rated products that hold up fine against the gusts common near the water. Standing seam metal costs more up front but sheds our heavy winter rain fast, resists moss better than any other common material, and tends to outlast two or three shingle roofs over the life of the house. Synthetic composite shake is worth a look if you want the look of cedar without cedar's moisture problems. Traditional cedar shake and clay or concrete tile both have real drawbacks in this climate that we'll get into below — they're not automatically wrong, but they need to be chosen with eyes open. Alpine Exteriors installs and repairs all of these, and in our experience the roofs that perform best here are the ones where the material, the ventilation and the flashing details were all considered together, not just the shingle color.
We're not ranking these materials on looks or brand reputation. The criteria below are the ones that actually determine whether a roof holds up on a Fidalgo Island or Skagit County home:
This is still the most common roof covering we install across Mount Vernon, Burlington, Sedro-Woolley and much of Anacortes, and for good reason. Modern architectural shingles rated for higher wind speeds hold up well against the gusts that come off the flats and the Strait, and the material is forgiving of the complex rooflines common on remodeled farmhouses and split-levels throughout the county. Cost is moderate compared to metal or tile, and most licensed roofers in the region — Alpine Exteriors included — can source, install and repair them without long lead times.
Pros: Lower upfront cost, wide color and style selection, straightforward repairs, good wind ratings available, works with standard synthetic underlayment and ice-and-water shield at eaves and valleys.
Cons: Shortest realistic lifespan of the mainstream options in a wet climate, and shaded roofs will grow moss faster on asphalt than on metal — a north-facing shingle roof under fir trees in Anacortes can need moss treatment or gentle cleaning every couple of years. Granule loss accelerates in driving winter rain over time.
Metal has become a common upgrade choice on both new builds and reroofs in Skagit and Island counties, especially on homes with simpler rooflines and on waterfront or bluff properties where wind and salt exposure are higher. The interlocking seams shed our heavy winter rain quickly, the smooth surface holds far less moss than shingles or shake, and a quality standing seam system with proper fasteners handles wind loads well.
Pros: Long service life, excellent rain-shedding, strong moss resistance, good performance in wind, and coated steel or aluminum panels resist the corrosion that plain galvanized fasteners can suffer near saltwater.
Cons: Highest material and installation cost of the common options. Noise during heavy rain can bother some homeowners without adequate attic insulation (this is a real but often overstated concern — proper decking and insulation largely solve it). Panel and fastener quality varies a lot between installers, and a poorly detailed metal roof near saltwater can actually corrode faster than a well-installed asphalt roof, so installer experience matters more here than with shingles.
These engineered products mimic the look of cedar shake or natural slate using polymer or rubber composites. They've become a reasonable middle path for homeowners in Anacortes and Bellingham-area neighborhoods who like the traditional Pacific Northwest shake look but don't want the maintenance that comes with real wood.
Pros: Resists moisture absorption and rot far better than real cedar, holds color well, generally carries strong wind ratings, and needs less maintenance than either cedar shake or clay tile.
Cons: Costs more than asphalt shingles, product quality and warranty terms vary significantly by manufacturer, and it's a less common installation locally, so not every roofing crew has deep experience with it — ask specifically about a contractor's track record with the product before choosing it.
Cedar has deep roots in this region's building tradition, and it still shows up on older homes and some new construction from La Conner to Sedro-Woolley. It's a legitimate look for the area, but it comes with the most honest trade-offs of any material on this list.
Pros: Natural regional aesthetic, good insulating properties, can be treated for fire resistance where required.
Cons: This is where our climate is least forgiving. Cedar left untreated in our wet, shaded conditions grows moss and algae quickly, and moisture retention leads to premature rot, especially on north-facing slopes under mature trees — a very common situation in wooded Anacortes and Camano Island lots. Real longevity requires periodic cleaning, moss treatment and occasional shingle replacement, which most homeowners underestimate when they choose it. We won't talk anyone out of cedar who wants the look and is willing to maintain it, but we're honest that it's the highest-maintenance option here, not the lowest.
Tile roofing is uncommon in this part of Washington, and for practical reasons. It's heavy, and many older homes in Mount Vernon, Anacortes and the surrounding towns weren't framed with tile's dead load in mind, which can mean costly structural reinforcement before installation is even possible.
Pros: Very long material lifespan, fire resistant, distinctive look.
Cons: Significant weight requires structural evaluation and often reinforcement, higher installed cost, and it's simply not a common product locally — fewer installers, longer lead times on materials, and repair parts can be harder to source quickly after storm damage. For most homes in this region, tile's benefits don't offset these practical hurdles.
| Material | Typical installed cost range | Moss resistance | Best fit here |
|---|---|---|---|
| Architectural asphalt shingle | $$ | Fair, needs periodic treatment on shaded roofs | Most homes, budget-conscious reroofs |
| Standing seam metal | $$$$ | Very good | Waterfront, bluff-top, and long-term owners |
| Synthetic composite shake | $$$ | Good | Homeowners wanting a shake look with less upkeep |
| Cedar shake | $$$ | Poor without maintenance | Owners committed to regular upkeep and treatment |
| Clay or concrete tile | $$$$ | Good | Rarely the practical choice locally |
A few choices consistently cause problems for Skagit and Island County homeowners, and they're worth flagging directly. First, skipping ice-and-water shield membrane at eaves, valleys and around penetrations is a mistake in this climate — our long rainy season and the occasional hard freeze mean water backing up under shingles is a real risk, not a theoretical one, and that membrane is inexpensive insurance against it. Second, choosing a low-wind-rated shingle product to save a little money on an open, exposed lot near the flats or the water is a false economy; the wind gusts common between Mount Vernon and the Strait will find the weak product eventually. Third, installing any roof without addressing attic ventilation is a problem the Washington State Energy Code's ventilation and insulation provisions exist specifically to prevent — trapped moisture rots decking from underneath regardless of how good the surface material is. Fourth, on shaded lots under conifers, choosing an organic, moisture-absorbing material like untreated cedar without committing to a real maintenance schedule sets the roof up to fail years before its rated lifespan. And finally, near saltwater, using plain galvanized fasteners or flashing instead of corrosion-resistant hardware is a common shortcut that causes rust stains and leaks well before the roofing material itself has worn out.
On a north-facing or heavily shaded roof under fir or cedar trees, plan on inspecting for moss at least once a year and treating or gently cleaning it every one to two years, depending on tree cover. Left unchecked for several years, moss holds moisture against the roofing material and can shorten its life significantly, regardless of whether the roof is asphalt, cedar or composite.
Yes, to a meaningful degree. Salt-laden air accelerates corrosion on exposed metal fasteners, flashing and gutter hardware, so homes within roughly a mile or two of saltwater benefit from corrosion-resistant metal components even if the main roofing material — shingle, metal panel or composite — stays the same choice you'd make further inland.
It depends on how long you plan to stay in the house and how exposed your roof is. On a sheltered, tree-covered lot with a straightforward roofline, a good architectural shingle roof can perform well and cost considerably less. On an open, wind-exposed or waterfront property, or for an owner planning to stay long enough to amortize the higher upfront cost, standing seam metal's rain-shedding and moss resistance often make the added expense worthwhile.
The energy code's insulation and ventilation requirements affect how your roof assembly is built beneath the visible surface — proper attic or cathedral ceiling ventilation, insulation levels and air sealing all interact with the roofing material you choose. Skipping these details to save money on a reroof can lead to trapped moisture and premature deck rot even if the shingles or metal panels themselves are high quality, so it's worth discussing with your contractor during the estimate.
There's no single best roof for every house in Anacortes, Mount Vernon, Burlington, Sedro-Woolley, La Conner, Stanwood, Camano Island or Bellingham — the right choice depends on your tree cover, exposure to wind and salt air, roofline, and how much maintenance you actually want to take on.
