Commercial Roofers in Lewiston, ID

Lewiston's climate is distinct from the rest of Idaho. At just 738 feet — the lowest point in the state — it avoids the extreme cold that defines much of the region. Winters are milder with less snow, but the river valley traps moisture and creates fog. Rainfall is higher than the high-desert areas, around 12 inches. Summers are hot, and the valley setting limits airflow.

Commercial roofs in Lewiston deal with more moisture and less extreme cold than most of Idaho. The river valley humidity, fog, and rain are the primary stressors rather than snow loads and deep freezes. However, enough freeze-thaw cycling still occurs, and the summer heat in the sheltered valley wears on rooftop materials. The port district and commercial areas along the river face the most moisture exposure.
