Roofs in Ilwaco and Chinook face a combination you won’t find inland: salt air from the ocean and Baker Bay, storms that roll in off the Columbia River bar, and heavy moss on tree-shaded lots. The roofs that last here are installed for high wind, use corrosion-resistant fasteners and flashing, and are made from materials suited to marine air — typically high-wind-installed shingles or a metal roof chosen for salt exposure. Here’s what south Peninsula homeowners should know before repairing or replacing.

What Makes Ilwaco and Chinook Hard on Roofs
Ilwaco sits at the south end of the Long Beach Peninsula on Baker Bay, just inside the mouth of the Columbia River, with Cape Disappointment and its lighthouses standing guard to the west. Chinook lies a few miles east along Highway 101 on the same bay, toward the Astoria-Megler Bridge. It’s a beautiful, working corner of the coast — and a demanding place for a roof.
- River-bar storms. The Columbia River bar is known for rough water, and the weather that builds there doesn’t stop at the shoreline. Winter storms bring strong wind and rain that moves sideways.
- Salt and marine air. Around the Port of Ilwaco and along the bay, marine air reaches nails, screws, flashing, vent caps, and gutters. On coastal roofs, metal parts often fail before the roofing itself.
- Hillside exposure. Homes on the hills above the port get wind from several directions.
- Shade and moss. Homes tucked into the trees — common in Chinook and the hollows around Ilwaco — stay damp, and moss takes over fast.
- Second homes. Many south Peninsula homes are part-time residences, so storm damage can go unnoticed for weeks.

Best Replacement Roofs for Ilwaco Homes
Metal roofing: choose the right metal
Metal roofing is a strong choice on the south Peninsula: it sheds wind-driven rain, resists moss, and lasts a long time. The key decision is the metal itself.
- Aluminum doesn’t rust, which makes it a strong candidate for homes closest to salt water.
- Coated steel can perform well a little farther from the water, but corrosion can begin at cut edges, scratches, and exposed fasteners.
- Standing seam systems hide most fasteners under raised seams, removing many potential leak and rust points compared with exposed-fastener panels.
- Warranty fine print: some metal and coating warranties limit coverage close to salt water. Ask to see the coastal terms for any product you’re quoted.
High-wind shingles
Architectural shingles remain a practical, familiar choice in Ilwaco and Chinook — when they’re installed for wind. That means following the manufacturer’s high-wind installation instructions, starter strips at eaves and rakes so edges seal down, secured ridge caps, and corrosion-resistant nails.
| High-wind architectural shingles | Coated steel (standing seam) | Aluminum (standing seam) | |
|---|---|---|---|
| Salt-air resistance | Good; fasteners and flashing are the weak points | Good away from direct spray; watch cut edges | Excellent; doesn’t rust |
| Wind performance | Good when installed to high-wind instructions | Very good with proper attachment | Very good with proper attachment |
| Moss resistance | Moderate; needs cleaning in shade | High | High |
| Upkeep | Moderate | Low | Low |
| Relative investment | Lower | Higher | Highest |
| Good fit for | Budget-conscious re-roofs, homes away from direct spray | Long life with moderate salt exposure | Waterfront and most-exposed homes |

Chinook & Baker Bay: Trees, Shade, and Moss
Chinook’s homes along Baker Bay and in the wooded hills behind it often sit under big trees. That shade keeps roofs wet, and moss follows. Moss holds water against shingles, lifts their edges, and pushes moisture into the decking.
- Clean and treat early. Regular roof cleaning and moss treatment slow the damage on a roof that still has life left.
- Improve ventilation. A roof that can’t dry from below rots faster.
- Trim back overhanging limbs where it’s safe to do so, to let in light and cut debris.
- Keep gutters clear so water moves off the roof instead of backing up.
- Consider metal at replacement time. Its smooth surface gives moss little to hold on to.

After a Storm: What to Do Before You Call
Storms off the river bar can strip shingles, damage vents, or tear off sections of roof. If it happens to you:
- Stay safe. Don’t climb on a wet or damaged roof.
- Protect the inside. Move belongings away from leaks and catch dripping water.
- Take photos of damage inside and out (from the ground), including any debris in the yard.
- Call for an emergency patch. A temporary repair stops further water damage until permanent work can be done.
- Contact your insurance company if the damage may be covered. See will insurance pay for a new roof?.
- Get a full inspection once the weather settles, so hidden damage isn’t missed.

Frequently Asked Questions
Do roofers serve Ilwaco and Chinook, or just Long Beach?
Apple Roofing serves the whole Long Beach Peninsula, including Ilwaco and Chinook, as well as Long Beach, Seaview, and Ocean Park — and Astoria just across the bridge.
What’s the best roof for a home near the Port of Ilwaco or Cape Disappointment?
For the most exposed homes, a metal roof made from a material suited to salt air — often aluminum — with concealed fasteners is a strong choice. High-wind-installed architectural shingles with corrosion-resistant nails and flashing are a practical alternative.
Will a metal roof rust in Ilwaco’s salt air?
Aluminum won’t rust. Coated steel can corrode starting at cut edges, scratches, and exposed fasteners, so material choice, installation details, and the warranty’s coastal terms matter.
How long does a roof last in Ilwaco?
Wind, salt, and moss shorten roof life on the south Peninsula compared with inland areas. Installation quality, corrosion-resistant fasteners, ventilation, and moss control make the biggest difference.
Do I need a permit to replace a roof in Ilwaco?
Requirements can differ between the City of Ilwaco and unincorporated Pacific County. Check with the appropriate building department before work begins; your contractor should know what’s needed.
What causes moss on Chinook roofs and how do I stop it?
Shade, moisture, and debris from overhanging trees. Regular cleaning and moss treatment, better ventilation, trimming limbs, and clear gutters all help. At replacement time, metal roofing resists moss well.
