Roofing in Washington

Washington splits between the wet Puget Sound and the dry Columbia Basin, and the roofs need to match each climate. The west side faces the rain, the moss, and the algae, and the east side faces the dry heat and the freeze-thaw cycles. Roofing in Washington means building roofs for every one of those climates — and we do it in 43 cities across the state.

The Roofing Regions of Washington

The state splits into two main roofing climates, and the roofs need to match each one.

The Puget Sound and the west — Seattle, Bellevue, Redmond, Kirkland, and the western cities — face the rain, the moisture, and the moss. The algae-resistant shingles and the regular cleaning are the standard.

The Columbia Basin and the east — Spokane, Kennewick, Richland, Pasco, Yakima, Wenatchee, and the eastern cities — face the drier climate, the freeze-thaw cycles, and the occasional snow.

Washington Roofing Considerations

The moisture is the dominant force in the western part of the state. The wet winters feed the moss and the algae on the north-facing slopes. The moss holds the moisture against the shingles and shortens the roof life.

The dry east brings the heat and the freeze-thaw cycles. The temperature swings stress the flashing and the seals.

The wind events test the roofs across the state.

Roofing in Washington’s Top Cities

• Puget Sound — Seattle, Bellevue, Redmond, Kirkland, and the western cities face the rain, the moisture, and the moss.
• The Columbia Basin — Spokane, Kennewick, Richland, Pasco, and the eastern cities face the drier climate, the freeze-thaw cycles, and the heat.

From the Puget Sound to the Columbia Basin, Washington roofs face the moisture, the moss, and the wind. The algae-resistant shingles, the regular cleaning, and the right installation make the difference between the 15-year roof and the 30-year roof.
