Here at Skyline Contracting, we know a thing or two about installing asphalt shingle roofs.
Asphalt fiberglass shingles remain a top choice for residential roofing thanks to their affordability, versatility, and ease of installation.But how long does a roof last when it’s made with asphalt fiberglass shingles? Ideally, an asphalt fiberglass shingle roof should last between 15 and 30 years—but many homeowners experience issues much sooner due to premature roof failure.
Wondering why your shingles didn’t last nearly as long as promised? You’re not alone—and we’re breaking down exactly why it happens.
-
- Improper Installation
- Extreme Weather
- Low-Quality Materials
- Poor Ventilation
- Lack of Maintenance
To help you get a quick overview, here are the top 5 reasons asphalt shingles often fail before their time:
1. Improper Installation: The Leading Cause of Shingle Failure
Even the best shingles won’t last if they’re installed improperly. Poor installation leads to shingles loosening, lifting, or blowing off during storms. Common mistakes include:
- Incorrect nailing – Nails placed too high or driven improperly reduce wind resistance.
- Improper sealing – Without proper adhesion, shingles are vulnerable to water intrusion.
- Misalignment – Gaps between shingles can let water in, causing leaks and decay.
Prevention Tip:
Hire a licensed roofing contractor with a track record of quality installations. A post-installation inspection can help catch issues early before they escalate. A reputable roofing company will follow the manufacturer’s specific installation guidelines to ensure optimal performance and prevent the potential void of your warranty.
2. Extreme Weather: Your Roof’s Constant Battle
Weather plays a major role in the lifespan of an asphalt fiberglass shingle roof. Constant exposure to sun, wind, and moisture wears down even high-quality materials.
- UV rays dry out shingles and cause granule loss.
- Heavy winds can loosen and lift poorly secured shingles, leading to damage and potential leaks.
- Rain and snow lead to moisture infiltration and rot.
- Freeze-thaw cycles expand trapped water under shingles, leading to cracks and shifting.
Prevention Tip:
Choose impact-resistant shingles, especially if you live in a storm-prone area. Post-storm inspections and preventative maintenance are crucial to the lifespan of your roof. A reputable roofing company will give you an honest assessment to avoid costly problems down the road.
3. Low-Quality Materials: Saving Now, Paying Later
Not all shingles are created equal. Budget materials may look fine at first, but they degrade faster under pressure.
- Accelerated granule loss reduces UV protection.
- Brittle materials crack during temperature swings.
- Weak adhesives increase the chance of early failure.
Prevention Tip:
Invest in architectural or premium-grade shingles from trusted brands. At Skyline Contracting, we recommend materials with high wind and impact ratings for long-term performance.
4. Poor Ventilation: The Hidden Threat
You might not see it, but a poorly ventilated attic can significantly shorten your roof’s life.
- Overheating causes shingles to blister and curl.
- Moisture buildup leads to mold and structural decay.
- Ice dams from uneven heat distribution damage shingles during winter.
Prevention Tip:
Ensure balanced intake and exhaust ventilation. Signs of poor ventilation include condensation in the attic and early shingle wear. A roofing professional can assess and improve your system.
5. Lack of Maintenance: Small Issues Become Big Problems
Regular maintenance can make or break your roof’s lifespan. Without inspections and upkeep, minor damage can spiral into full-blown failure.
Common signs of neglect:
- Patchy granule loss
- Curling or lifting shingles
- Moss or algae growth
- Leaks and water stains in the attic
Prevention Tip:
Schedule annual roof inspections and clean your gutters regularly. Replace damaged shingles right away to avoid deeper issues.
FAQs: What is the Average Asphalt Fiberglass Shingle Roof Lifespan?
How long does a roof last with asphalt fiberglass shingles?
Typically 15–30 years, depending on material quality, installation, and climate.
How do I know if my roofer is reputable?
A reputable roofer should be licensed and insured, be certified with the manufacturers they work with, and follow industry best practices. Also, look at the reviews online to see customer feedback and ensure they have a solid reputation. Licenses can be checked on the Secretary of State’s website.
Why are my asphalt shingles curling?
Curling shingles are often caused by heat, poor attic ventilation, or improper installation.
Can roof shingles fail due to poor ventilation?
Yes! Excess heat and moisture from poor ventilation can shorten an asphalt shingle’s lifespan. Our Georgia climate is not immune to this potential problem.
How often should I inspect my asphalt roof?
We recommend that an inspection is done at least once a year and after major weather events, as not all damage can be seen from the ground.
