Choosing the right roofing materials for Flagstaff isn’t the same as choosing for Phoenix or Tucson. At 7,000 feet elevation, our unique mountain climate demands materials that can handle heavy snow, intense UV rays, and extreme temperature swings. Here’s a comprehensive guide to help you make the right choice.
What Makes Flagstaff Roofing Different
Before diving into materials, let’s understand the challenges your roof faces in Northern Arizona:
- 100+ inches of annual snowfall – Materials must handle significant weight
- Intense high-altitude UV exposure – Accelerates material degradation
- Temperature swings of 40+ degrees daily – Causes expansion/contraction stress
- Monsoon season heavy rains – Tests water-shedding ability
- Hail and wind from thunderstorms – Impact resistance matters
Metal Roofing: The Top Choice for Flagstaff
Metal roofing has become increasingly popular in Flagstaff for good reason. It’s arguably the best material for our mountain climate.
Advantages:
- Excellent snow shedding – Snow slides off instead of accumulating
- 40-70 year lifespan – Longest lasting option
- Handles freeze-thaw cycles well
- Fire resistant – Important in forest areas
- Standing seam hides fasteners, preventing leak points
Considerations:
- Higher upfront cost ($9-15 per square foot installed)
- Requires snow retention systems for safety
- Some homeowners dislike the sound of rain/hail
Architectural Asphalt Shingles
Architectural (dimensional) shingles offer a good balance of performance and value for Flagstaff homes.
Advantages:
- More affordable than metal ($4-7 per square foot installed)
- Wide variety of colors and styles
- Proven performance in mountain climates
- Easier repairs than some alternatives
- 25-30 year warranties available
Considerations:
- Shorter lifespan than metal or tile
- UV degradation is accelerated at elevation
- Requires proper ice and water shield installation
- Not as fire resistant as metal or tile
Tile Roofing (Concrete or Clay)
Tile can work in Flagstaff, but requires careful consideration.
Advantages:
- 50+ year lifespan
- Excellent fire resistance
- Distinctive aesthetic appeal
- Low maintenance once installed
Considerations:
- Must use freeze-thaw rated tiles
- Heavy – requires adequate structural support
- Higher cost ($8-14 per square foot installed)
- Individual tiles can crack in extreme cold
Our Recommendation for Flagstaff Homes
Based on our experience with hundreds of Flagstaff roofs, here’s what we typically recommend:
- Metal roofing – Best overall choice for longevity and snow performance

Critical Installation Details for Any Material
Regardless of which material you choose, proper installation for Flagstaff’s climate requires:
- Ice and water shield at all eaves, valleys, and penetrations
- High-quality synthetic underlayment rated for temperature extremes
- Proper attic ventilation to prevent ice dams
- UV-stable sealants and flashing materials
- Proper slope for snow shedding
