Roofing in Juneau, Alaska

Roofing in Juneau, Alaska

Juneau sits at the base of Mount Juneau on the Gastineau Channel, the capital of Alaska and the heart of Southeast. It’s a rainforest town, with 60 to 90 inches of rain a year and a wet snow season at elevation. Roofing in Juneau means fighting moisture, moss, and maritime weather — the whole time keeping the state capital’s oldest homes watertight.

Local Roofing Considerations

The City and Borough of Juneau is one of the wettest places in the country. Rain is constant, especially from fall through spring, and the moisture finds every weak point in a roof. The north-facing slopes and shaded sections under the spruce and hemlock canopy grow moss that holds water against the shingles and speeds up wear.

Snow is a second factor, mostly at elevation. Neighborhoods up toward the Mendenhall Valley and the mountain slopes get heavy wet snow, which loads the roof and melts slowly in the maritime climate. Coastal salt air along the Gastineau Channel and Douglas Island adds corrosion to metal flashing and fasteners.

Juneau is a roadless city — no roads connect it to the rest of Alaska. That means materials come by barge and plane, which affects lead times and pricing. Permits run through the City and Borough building department, and downtown’s historic homes bring their own preservation considerations.
