Average Lifespan Typical Asphalt Shingle Roof

A durable roof provides peace of mind and significant cost savings over time, ensuring that a home or building remains protected from the elements for many years without the frequent need for repairs or replacements. In addition, a robust roofing system enhances the overall value of the property, making it a worthwhile investment. For these reasons, selecting high-quality, long-lasting shingles, such as those offered by brands like Malarkey, is a priority for many homeowners seeking to safeguard their homes and investments.

With the benefits of a long-lasting roof in mind, it’s important to understand the average typical lifespan of an asphalt shingle roof as well as the things that a homeowner can do to extend the life of their roof.

Average Lifespan Typical Asphalt Shingle Roof

The average lifespan of a typical asphalt shingle roof generally ranges from 20 to 40 years. However, this can vary depending on several factors including the quality of the shingles, the climate in which the roof is installed, how well the roof was installed, and the level of maintenance.

Weather conditions do play a significant role on how long roofing shingles will last. Roofs in areas with extreme weather conditions such as heavy snowfall, intense sunlight, high winds, or frequent hail, may have shorter lifespans due to increased wear and tear. In those areas, it is that much more important to choose higher-grade asphalt shingles, such as architectural or premium shingles, because they typically have longer lifespans compared to standard three-tab shingles. Architectural shingles can last up to 30 years or more.

With that said, installation by a qualified team of roofers is crucial for maximizing the lifespan of an asphalt shingle roof. Poor installation can lead to issues like leaks and shingle damage, which can significantly reduce the roof’s longevity. Regular maintenance, such as cleaning gutters, removing debris, and inspecting for damage, is also an important part of extending the life of an asphalt shingle roof. Promptly addressing any issues that arise, such as repairing damaged shingles or fixing leaks, can prevent issues from getting worse, which can quickly cut a lifespan short.

While the typical range for asphalt shingles is 20 to 40 years, with high-quality shingles, proper installation, and regular maintenance, some asphalt shingle roofs can last beyond this range.

Malarkey Shingles

Skyline Roofing carries Malarkey shingles, which are made with NEX polymer modified asphalt technology. This technology makes their shingles more durable than other brands. Malarkey shingles are also algae-resistant and can withstand winds up to 110 miles per hour. The lifespan of a Malarkey shingle roof varies depending on the specific product line

1. Legacy® Scotchgard™ shingles: These are premium architectural shingles designed for superior durability and weather resistance. They typically have a lifespan of 30 to 50 years.
2. Vista® shingles: These are also high-quality architectural shingles, known for their strength and resilience, with an expected lifespan of around 30 to 40 years.
3. Highlander® shingles: These are designed as a more affordable option while still offering good durability and performance. They generally have a lifespan of about 25 to 30 years.

Malarkey shingles are often praised for their impact resistance and ability to withstand harsh weather conditions, which can contribute to a longer lifespan compared to some other brands. Regular maintenance and proper installation are key to maximizing the lifespan of any shingle roof.

How to Know If It’s Time to Replace Your Roof

Knowing when it’s time to replace your roof is crucial for maintaining the integrity of your home and avoiding costly damage. Here are some key signs that indicate it might be time for a roof replacement:

1. Age of the roof. Most asphalt shingle roofs last between 20 and 30 years. If your roof is approaching or has surpassed this age, it’s wise to consider a replacement, even if it doesn’t show obvious damage.
2. Shingle condition. Inspect your shingles for signs of wear and tear. Curling, buckling, and protective granular loss are clear indicators that shingles are reaching the end of their lifespan. Additionally, if many shingles are missing or have fallen off, it’s a sign that the roof is failing.
3. Granule loss. Asphalt shingles are coated with granules that protect them from UV rays. If you find a large amount of granules in your gutters or around your downspouts, it means your shingles are deteriorating and may need to be replaced.
4. Leaks and water damage. Water stains on your ceilings or walls, or visible leaks in your attic, suggest that your roof is compromised. Persistent leaks can lead to structural damage, mold growth, and other serious issues.
5. Sagging roof. A sagging roof is a sign of significant structural problems. It could be due to weakened or rotting decking beneath the shingles, often caused by prolonged exposure to moisture. This requires immediate attention and likely a full roof replacement.
6. Moss and algae growth. While moss and algae themselves aren’t necessarily harmful, they can trap moisture against the roof surface, accelerating the deterioration of shingles. If your roof is heavily covered in moss or algae, it might be time to consider replacement, especially if other signs of aging are present.
7. Energy bills. A failing roof can affect your home’s insulation, leading to increased energy bills. If you notice a spike in your heating or cooling costs, it could be due to an inefficient roof.
8. Daylight through roof boards. If you can see daylight coming through the roof boards when you’re in the attic, it means there are gaps or holes in your roofing material, indicating that it’s time for a replacement.

Regular inspections and maintenance can help you catch these issues early. If you’re unsure about the condition of your roof, consulting a professional roofing contractor for an assessment can provide clarity and help you decide if it’s time for a replacement.
