What Are 2 Disadvantages to Asphalt Shingles?
We’ve noticed many homeowners asking about the drawbacks of asphalt shingles before making their roofing decisions. While these shingles remain America’s most popular roofing choice, they come with notable limitations that every property owner should consider. Let’s explore two significant disadvantages that could impact your long-term satisfaction and investment: their relatively brief lifespan and concerning vulnerability to weather damage for best roofing Peoria.
Key Takeaways
- Asphalt shingles have a relatively short lifespan of 25-30 years compared to metal roofs lasting 70 years and slate lasting 200 years.
- High winds over 58mph can easily damage and lift asphalt shingles from the roof, requiring repairs or replacement.
- Asphalt shingles create 11 million tons of non-biodegradable waste annually in the U.S., contributing to environmental pollution.
- Temperature fluctuations cause shingles to expand and contract, leading to cracks and deterioration over time.
- Regular maintenance and twice-yearly professional inspections are required, increasing long-term ownership costs.
Short Lifespan of Asphalt Shingles
While many homeowners choose asphalt shingles for their affordability, we can’t ignore their particularly short lifespan compared to other roofing materials.
Even high-end luxury asphalt shingles typically last only 25-30 years, while metal roofs can endure up to 70 years, and slate roofs can protect homes for up to 200 years!
We’ve found that 3-tab shingles, the most common variety, generally need replacement after just 15-20 years, especially in warmer climates.
When you consider that proper installation and regular maintenance are essential for achieving even these modest lifespans, it’s clear that longevity isn’t asphalt’s strong suit.
Vulnerability to Weather Damage
Despite their widespread use in residential roofing, asphalt shingles demonstrate significant vulnerabilities to various weather conditions that can compromise their integrity.
We’ve found that high winds exceeding 58mph can lift and detach shingles, while extreme temperature fluctuations cause them to expand and contract, leading to cracks.
Let’s not forget how precipitation poses serious risks too – from hail damage to granule loss from heavy rain.
What’s particularly concerning is how these weather-related issues compound over time, as aging shingles become more brittle and susceptible to damage, requiring prompt attention to prevent costly structural problems.
Environmental Concerns and Waste
The environmental impact of asphalt shingles extends far beyond the weather-related damage they endure, presenting serious ecological challenges throughout their lifecycle.
We’re seeing these petroleum-based products contribute greatly to pollution during manufacturing, releasing harmful VOCs and greenhouse gases into our atmosphere.
What’s more concerning is that they’re filling up our landfills at an alarming rate, with 11 million tons of waste generated annually in the U.S. alone.
When they break down, these non-biodegradable materials can leach dangerous chemicals and heavy metals into our soil and groundwater, creating long-lasting environmental hazards that affect our communities.
Maintenance Requirements and Repair Costs
Maintaining asphalt shingle roofs demands consistent attention and a proactive approach that’ll greatly impact your home’s long-term protection.
We recommend scheduling professional inspections twice a year to catch issues early, which can save you thousands in potential repairs.
Let’s not forget about seasonal maintenance – we’ll need to clean those gutters regularly and remove debris that can trap moisture, leading to costly damage.
When you consider the expenses of replacing damaged shingles, fixing corroded flashing, and treating moss or algae growth, you’ll find these maintenance tasks are essential for protecting your investment.
Frequently Asked Questions
How Much Do Professional Asphalt Shingle Installations Typically Cost per Square Foot?
We’ll typically pay between $3.50 and $5.50 per square foot for professional asphalt shingle installation, including labor and materials. Local prices may vary depending on shingle quality and availability.
Can Asphalt Shingles Be Installed Over Existing Roofing Materials?
We don’t recommend installing asphalt shingles over existing roofing. It voids warranties, violates building codes, adds excessive weight, and can trap moisture that leads to structural damage.
What Is the Minimum Roof Slope Required for Asphalt Shingle Installation?
As solid as a rock, we need a minimum slope of 2:12 for asphalt shingles, though we’ll get better performance with 4:12. Anything less won’t drain properly.
Are There Specific Warranty Differences Between Different Manufacturers of Asphalt Shingles?
Yes, we’ll find significant warranty differences among manufacturers, including varying durations, coverage terms, and requirements for complete roofing systems to qualify for enhanced protection plans.
How Do Energy Costs Compare Between Homes With Asphalt Versus Metal Roofing?
We’ll find higher energy costs with asphalt shingles since they absorb heat, while metal roofs reflect sunlight and reduce cooling expenses. Adding insulation under either type improves efficiency.
Final Thoughts
Like a fair-weather friend who disappears during storms, we’ve seen how asphalt shingles can let us down when we need them most.
