Selecting the right roofing material for your home is an important decision that requires careful consideration of your local climate. Asphalt, metal, and tile – the three most common roofing types – each have their own strengths and weaknesses when it comes to withstanding heat, cold, rain, wind, and other environmental factors. This comprehensive guide compares the climate-specific performance of asphalt, metal, and tile roofs to help you determine the best option for your weather conditions.
Why Climate Matters for Roof Performance
The climate in your area impacts your roof in multiple ways over its lifetime:
- Temperature – Extreme heat and cold cause expansion and contraction that can lead to cracks and leaks.
- Precipitation – Heavy rain and snowfall exert additional weight and pressure on your roof.
- Wind – Strong winds can lift shingles or cause puncture damage from flying debris.
- Sunlight – Constant sun exposure can cause discoloration, weathering, and deterioration.
Choosing a roof not suited for your climate will likely result in roof failures, leaks, and costly repairs or replacements much earlier than expected. Carefully evaluating how well each material handles your particular conditions will save you money and headaches down the road.
Key Factors by Climate Type
Hot and Dry:
- Withstand high temperatures and heat radiation
- Reflective abilities to reduce cooling costs
- Resist cracking and drying out
Cold and Snowy:
- Handle heavy snow loads without collapse
- Resist ice dams and interior water leaks
- Endure extreme sub-freezing temperatures
Wet and Rainy:
- Shed large volumes of rain and moisture
- Resist leaks with proper water drainage
- Withstand high winds and storm impacts
Now let’s dive deeper into how the three most common roofing materials – asphalt, metal, and tile – stack up in these regards.
Asphalt Shingle Roofs
Asphalt shingles are the most popular roofing choice in North America thanks to their affordability and ease of installation. But how do they fare across varying climates?
Asphalt Shingle Pros
- Low upfront cost – Much more affordable than metal or tile
- Easy installation – Quick and simple for roofers to work with
- Aesthetic options – Manufactured in a wide variety of colors and textures
- Good fire resistance – Meet building code standards for fire safety
Asphalt Shingle Cons
- Shorter lifespan – Average of 15-20 years compared to metal and tile
- Susceptible to impacts – Can be damaged by severe hail, falling branches, etc
- Absorbs heat – Gets extremely hot in the sun, raising cooling costs
- High maintenance – Requires frequent inspections, repairs, sealant reapplication
Climate Performance of Asphalt Shingles
Hot and Dry Climates
- Brittle and crack easily from constant heat exposure and drying
- Prone to premature breakdown and lifespan reduced by 30% or more
- Require reflective coatings or adequate shade for longevity
Cold and Snowy Climates
- More vulnerable to ice dams causing interior leaks
- At risk of cracking and splitting in extreme sub-freezing weather
- Black shingles absorb heat from sunlight, worsening snow melt
Wet and Rainy Climates
- Absorb moisture easily and require good attic ventilation
- Heavy rainfall accelerates wear and can lead to leakage
- Moss and mildew growth likely needing frequent cleaning
- Vulnerable to wind uplift and damage from falling branches
Cost and Maintenance
- Low Upfront Cost: $100-300 per square installed
- Frequent Inspections: Should be done annually
- Moderate Maintenance: Sealant reapplication every 5-7 years and as needed
- Frequent Replacement: New roof needed every 15-25 years
Asphalt shingles provide an affordable short-term roofing option best suited to temperate climates with milder weather. Their lower durability makes them a poor choice for extreme weather conditions.
Metal Roofing
Metal roofs are growing in popularity thanks to their durability, longevity, and energy efficiency. Let’s examine how metal stands up to varying climate conditions.
Metal Roofing Pros
- Long lifespan – Average 40-70 years with some lasting over 100 years
- Durable – Withstands all weather extremes and wind uplift forces
- Fire resistant – Meets all building code standards
- Low maintenance – Requires very minimal upkeep over lifetime
- Energy efficient – High solar reflectance reduces cooling costs
Metal Roofing Cons
- Higher upfront cost – Around $400-1000 per square installed
- Noise issues – Rain, hail, and debris can be loud
- Limited styles – Mostly limited to solid colors and simulated shingles
- Dents possible – Susceptible to dings and scratches from impacts
Climate Performance of Metal Roofs
Hot and Dry Climates
- Exceptional heat reflection ability dramatically reduces cooling costs
- Withstands extreme sun and heat exposure without breakdown
- Resists drying, cracking and weathering from low humidity
Cold and Snowy Climates
- Allows snow to easily slide off to prevent ice dams
- Endures heavy snow loads with proper structural support
- Low chance of snow and ice accumulation
Wet and Rainy Climates
- Made from rust-resistant materials like aluminum and coated steel
- Sheds rain, sleet, and moisture without leaking
*bonds wind uplift and storm impacts well
Cost and Maintenance
- High Upfront Cost: $500-1500 per square installed
- Minimal Maintenance: Just occasional screw tightening and debris removal
- Long Replacement Time: 40+ years between new roof installations
With outstanding durability and climate resistance, metal is an ideal roofing choice in nearly any environment – especially harsh ones.
Tile Roofing
If budget allows, tile roofing provides unmatched beauty, longevity, and weather protection. But how does it handle varying climates?
Tile Roofing Pros
- Very long lifespan – Properly installed tile roofs last 50-100 years
- Aesthetically pleasing – Natural clay and high-end composite materials
- Good fire resistance – Meet highest building code standards
- Durable – Impact and weather resistant when installed correctly
- Variety – Many styles such as flat, barrel tile, etc.
Tile Roofing Cons
- Expensive – Costs $675 to $2500 per square installed
- Heavy – Weighs 780-1500 lbs. per square requiring reinforced infrastructure
- Brittle – Vulnerable to cracking if roof structure flexes
- Moss problems – Some types prone to moss growth limiting runoff flow
Climate Performance of Tile Roofs
Hot and Dry Climates
- Can absorb and retain extreme heat, increasing cooling costs
- Lighter color tiles or reflective coatings are recommended
Cold and Snowy Climates
- Withstands heavy snow loads with proper installment
- Risk of water seeping under tiles causing leaks
Wet and Rainy Climates
- Periodic moss removal required in wet, shaded areas
- Vital for adequate slope and drainage to prevent water pooling
- Wind and debris impacts can crack tiles over time
Cost and Maintenance
- Very High Upfront Cost: $800-2500 per square installed
- Moderate Maintenance: Moss cleaning every 3-5 years, replace cracked/missing tiles
- Low Long-term Cost: Very long useful life, only re-roofing needed every 50+ years
Tile roofing excels in all climates when installed correctly. Paying extra installation costs for structural enhancements and professional-grade materials leads to a lifetime roof with minimal upkeep.
Direct Comparison of Materials by Climate
| Material | Hot & Dry | Cold & Snowy | Wet & Rainy |
|---|---|---|---|
| Asphalt | Poor climate match – absorbs heat, prone to cracking | Marginal climate match – vulnerable to ice dams and snow loads | Poor climate match – retains moisture leading to leaks |
| Metal | Excellent match – reflective, durable in heat | Excellent match – allows snow to slide off, avoids ice dams | Excellent match – resists rust, sheds precipitation |
| Tile | Good match with light colors and coatings | Good match with professional installation | Fair match needs diligent cleaning to prevent water pooling |
Other Roof Selection Considerations
Beyond climate, other important factors include:
- Budget – Tile and metal cost more upfront than asphalt
- Aesthetics – Asphalt and tile offer more color/style choices than metal
- Roof Pitch – Low pitch best for asphalt, high pitch suited for tile
- Energy Savings – Metal most energy efficient through heat reflection
- Eco-Friendliness – Metal and tile easier to recycle than asphalt composites
- DIY Installation – Asphalt easiest for DIY, tile and metal require professionals
- Home Value – Tile and metal boost resale value more than asphalt
- Maintenance Effort – Metal lowest maintenance, asphalt highest
- Weight Considerations – Heavy tile may require roof structure reinforcement
- Wildfire Resistance – Metal rates best with tile second
