How Long Do Asphalt Roofs Last in the Twin Cities?

Asphalt shingles are the most popular roofing material throughout the United States, including throughout Minneapolis and St. Paul. There is good reason for this popularity. Asphalt shingles offer an excellent balance of affordability, durability, and curb appeal.

However, just because they have durability advantages doesn’t mean they never get old or fail. In the Twin Cities, many factors will influence the lifespan of your asphalt roof. To learn more about these factors and what to do as your roof nears the end of its life, keep reading. The rest of this post will provide all the information you need to keep your asphalt roof performing at its best.

What is the Average Lifespan of an Asphalt Roof?

First, let’s discuss some averages. An average asphalt shingle roof typically lasts 15-30 years. Several factors influence how long your roof will perform optimally. These include:

• The type of asphalt shingles installed.
• The quality of the roofing installation.
• Ventilation and attic insulation.
• Routine maintenance.
• Storm damage.
• Tree coverage and debris accumulation.
• Minnesota’s seasonal weather conditions.

Types of Asphalt Shingles and Their Expected Lifespan

In addition to regional factors, such as the Twin Cities’ weather and the quality of the installation, the main factor affecting shingle lifespan is the type of asphalt shingle used.

There are three main types of asphalt shingles: Three-tab, architectural, and luxury. Below, we examine each in more detail.

Three-tab shingles

Three-tab shingles are the traditional single-layer shingle seen on many Minneapolis homes. They remain a popular choice because of their affordability.

While three-tab shingles do provide reliable protection when new, they have the shortest lifespan of any asphalt shingle. They typically last only 15-20 years and are especially susceptible to Minnesota’s freeze-thaw cycles.

Homeowners looking for a budget-friendly roof replacement with a wide range of color options should consider this option.

Architectural shingles

Architectural shingles are also known as dimensional or laminated shingles. They are a very popular choice, especially in climates like Minnesota’s.

These shingles are constructed with multiple layers of asphalt, which provides greater thickness, durability, and weather resistance. Typically, architectural shingles last longer than three-tab shingles, approximately 25-30 years.

Homeowners looking for a shingle engineered to withstand high winds, heavy snow, and hail should consider this option. However, keep in mind that architectural shingles are more expensive than their three-tab counterparts.

Luxury shingles

Luxury shingles are the highest-end asphalt shingle type. They are designed to mimic slate or cedar shakes without the added weight or maintenance. They also have a thicker construction, which offers superior durability, impact resistance, and long-term performance.

Luxury shingles have the longest lifespan of the asphalt shingles, with most lasting 30-40 years.

Choose the luxury shingle if you have a large budget and want a high-end look while benefiting from modern roofing technology.

How Twin Cities Weather Affects Asphalt Roofs

Minnesota’s weather affects nearly all aspects of home maintenance and repair, and your asphalt roof is no different. How well your shingles deal with weather in the Twin Cities will significantly impact their lifespan. Some of the most common weather events that affect shingle lifespan include:

• Heavy snow: Snow accumulation puts a lot of weight on your roof throughout the winter. Modern roofing systems take snow accumulation into account, but excessive snow load over many years can contribute to the normal wear and aging of your shingles.
• Ice dams: Ice dams are a common occurrence in Twin Cities homes. When heat escapes through the attic, snow melts and refreezes near the roof’s edge, causing water to back up beneath the shingles. Ice dams can crack or otherwise damage your asphalt shingles.
• Hailstorms: Hail is one of the leading causes of premature asphalt roof damage. After major storms, always consider a professional roof inspection from SMC Construction, Inc..
• High winds: Spring and fall are times of many high winds in Minneapolis. These can lift or tear shingles, causing damage that reduces your roof’s lifespan.
• Freeze-thaw cycles: Repeated freeze-thaw cycles place stress on shingles, flashing, and roofing sealants. This stress can accelerate normal aging.

Signs Your Asphalt Roof Needs to be Replaced

Knowing the average lifespan of your asphalt roof is just the first step. Every home is unique, and your asphalt roof may have a lifespan that is longer or shorter than average.

That is why you will also need to look for signs that your roof is beginning to fail. Finding the issue early can help you plan for roof replacement before minor issues become emergencies. Common warning signs that your asphalt roof needs replacement include the following:

• Curling or buckling shingles
• Missing shingles
• Granule loss
• Frequent roof leaks
• Moss or algae growth

How to Extend the Life of Your Asphalt Roof

While no shingle will last forever, there are some steps you can take to increase the potential lifespan of your roof. These include:

• Scheduling regular roof inspections from a professional contractor, such as SMC Construction, Inc.
• Keep your gutters clean to reduce moisture-related roof problems.
• Trim overhanging trees to keep branches from rubbing against shingles and reduce debris on the roof.
• Address small repairs promptly to prevent a costly replacement.
• Maintain proper attic ventilation to keep roof temperatures stable all year.

In addition to these tips, the best way to ensure your roof reaches its potential is to have it installed by professionals.

FAQs

Want to know more about asphalt shingles and their lifespan in the Twin Cities? Here are the answers to a few of our customers’ most commonly asked questions.

Can a roof last 30 years in Minnesota? Yes. However, it needs to be made with premium materials, installed correctly, and maintained regularly. Routine inspections and timely repairs are essential to extend the life of your asphalt roof in the Twin Cities.

Should I replace my roof after hail damage? While hail does cause damage to shingles, a single hailstorm does not mean you need a roof replacement. However, we highly recommend that you receive a professional inspection after every hailstorm, as not all hail damage is visible from the ground.

How often should I have my roof inspected in Minneapolis? Most roofing professionals recommend having your roof inspected at least once per year or after any major storms. Inspections at this frequency allow you to identify damage before it worsens and requires a complete roof replacement.
