Because Kalispell sees heavy snow, hail, and large temperature swings, most asphalt shingle roofs last around 20–25 years with proper maintenance. High-performance materials like Malarkey architectural shingles or standing seam metal roofs can last 40–50 years or more when installed by a certified contractor like Sisu Roofing.
For homes in the Flathead Valley, impact-rated asphalt shingles and standing seam metal roofs offer the best durability. Malarkey’s rubberized shingles hold up exceptionally well against hail and UV exposure, while metal roofing resists snow buildup and wildfire risk — both excellent choices for Kalispell homeowners.
