Asphalt shingles are still a common roofing material in the United States, but the truth is, they’re far from being the most reliable option available. These shingles aren’t durable, have short lifespans, and decay over time, making them inferior to metal roofing. Check out our helpful summary to discover common asphalt shingle roof problems homeowners experience.
Asphalt Shingles
Asphalt shingles have been around since the 1920s. Years ago, asphalt shingles, also called organic shingles, consisted of a heavy felt-like material that was saturated with asphalt, making them water resistant. The shingles were then coated with adhesive asphalt and stone-like granules that were ingrained within the shingles.
Organic shingles contained at least 40% more asphalt than the fiberglass shingles that are made today, which provided more weight, durability, and resistance to wind.
Back in the day, you could get 30–35 years out of an asphalt roof.
Starting in the late 1980s and early ‘90s, the composition of the asphalt shingle changed dramatically. To keep the cost of asphalt shingles down, primarily due to rising oil costs, heavy felt paper was replaced with a lighter weight fiberglass material. Fiberglass became very popular because the material is far less expensive, easier to produce, and easier to work with.
The fiberglass mat is coated with a mineral filler which adheres to the mat to help make it waterproof. A final adhesive coating is used with additional ceramic granules that are embedded into the mat. A significant amount of the granules consists of limestone, which attract airborne algae, leading to granule loss and the unattractive dark streaking you see today.
Metal roofs don’t streak— not now, and not 50 years from now.
The Lifespan of Asphalt Shingles
Today, asphalt shingles sometimes last 15-20 years on average. The significant decrease in the life of the asphalt shingle is due to the cheaper materials and the lack of oil and asphalt content. Longevity also depends to some degree on how and where the shingles are installed.
- Shingles found in cooler locations will have a longer lifespan than in warmer climates.
- The average lifespan in hotter locations like the southwest is typically 14 years, and here in Ohio and western Pennsylvania, the average lifespan is approximately 15–20 years.
Warning
Before asphalt roofing even passes the 10-year mark, it typically falls victim to granule loss, cracking, splitting, algae streaking, and other signs that the roof is breaking down.
Seemingly Small Problems
Extremes in temperatures will have a major effect on the life of asphalt shingles. Warmer climates will limit the life of a shingle. Asphalt shingles that are exposed to extreme temperature changes within a short period of time will lead to:
❌ Premature splits and cracks
❌ Other damage due to intense expansion and contraction
Splits, cracks, and other damage that’s left exposed to extreme temperature changes can lead to water getting into those areas and creating further damage.
Shingle granule loss is what it sounds like – the panel is literally beginning to deteriorate. Although it isn’t always noticeable at first, a clear sign of shingle granule loss is looking in your gutters and finding them filled with granules.
To see what is happening with your asphalt roof:
-
- If you’re comfortable with getting on a ladder and feel safe doing so, inspect the first couple of rows of shingles
- Look for uneven granule coverage, including spots where you can see the fiberglass pad underneath
- Check your gutters; they’ll likely contain a large number of granules
- Look for splits, cracking, and curling within the shingles
- From the ground, look for black algae streaking (most common on the north side of the structure)
- If you spot significant signs, schedule a professional inspection to understand your roof’s overall health and avoid further damage
Factors That Affect the Life Expectancy of Asphalt Shingles
- Multiple-layer roof – An asphalt roof installed over an existing layer of asphalt will have a shorter life
- Installation – Poorly or improper installation will shorten the roof life
- Attic ventilation – An unventilated or poorly ventilated attic will reduce the life of the shingle
- Trees near the roof – Trees blocking the sun from reaching your roof can lead to algae and fungus forming on the roof, causing the roof to break down prematurely
- Harsh climate – Severe weather, harsh winters, hot summers, and extreme temperature changes can cause an asphalt roof to age quickly
At home and garden shows and customer meetings, we’ve spoken with many homeowners who have struggled with asphalt roofs that have failed well before what was promised.
We’ve heard from thousands of disillusioned homeowners whose roofs failed in
9 years or less.
Watch the Warranty Fine Print
Many homeowners were sold “35-year” warranties only to learn they were pro-rated and worth pennies on the dollar after just 10–15 years. In most cases, only manufacturing defects are covered—not the circumstances that actually lead to roof failure. Pro-ration protects the manufacturer, so by the time you need the warranty, it’s often expired or worth far less.
Distinctive Metal Roofing doesn’t let this happen to our customers, because we proudly offer the best warranties in the roofing industry, all of which are non-pro-rated. A metal roof from Distinctive Metal Roofing is truly the last roof you’ll ever need.
How to Avoid Roofing Problems
So, now that you know the common asphalt shingle roof problems, how can you avoid them? The best method for side-stepping these issues is by choosing a better material from the outset.
For instance, high-quality metal roofing can protect your home for more than 60 years without a problem. One major benefit of using metal roofing for your home is its energy efficiency. Metal roofs receive a finish of Kynar 500 coating, which reflects UV rays and greatly reduces the indoor house temperature. Open attic spaces show a 30 degree decrease when a metal roof was installed vs. and asphalt roof. By using less electricity cooling the home, you’ll see lower energy costs throughout the hot summer months. Plus, the Kynar 500 coating will resist chalking and fading, so your roof will maintain its color and beauty over the life of the product.
If you want reliable performance, always choose a metal roofing expert with years of experience and plenty of happy customers. With a professionally installed metal roof, maintenance needs are rare and you will have a roof that will protect your home for a lifetime!
