Long lasting asphalt shingle roofing. Your roof’s lifespan will be directly influenced by the way it was manufactured, your climate, and how well it was maintained over the years. Steeper sloped roofing has a longer lifespan than flat roofs that don’t allow water and debris to flow off as easily.  While there are different types of asphalt roof shingles, most last between 20-30 years. Read on to gain valuable insight into how long your asphalt roofing is expected to last, and how to prolong its lifespan. 

Factors That Influence How Long Your Roof Will Last

1. Local Weather

The weather your asphalt shingles stand up to is a major contributor to how long it will last. Brutal storms impact the lifespan of shingles significantly. The intensity and frequency of storms also weighs into your roof’s lifespan.  Minneapolis, Waite Park, and St. Cloud area homeowners are accustomed to Minnesota winters. Below freezing temperatures, snow, freezing rain, sleet, and ice are all common—and your roof stands up to these challenging elements 24/7! No wonder it’s so important to choose durable roof shingles made by industry-leading manufacturers for your roof’s longevity! 

2. Attic Ventilation

Your roof’s health is directly impacted by how well your attic is ventilated. A well-ventilated attic reduces the build-up of heat and moisture in your house and attic, extending the life of your roof. When you ventilate your attic properly, you decrease the possibility of damaging ice dams forming on your roof. Left unchecked, poorly ventilated attics can lead to roof leaks and void your manufacturer’s warranty.  

3. How Well You Maintain Your Roof

Is moss making your roof its home and growing without restraint on your rooftop? Did debris from the last major storm land on your roof—and it’s still there? Do ice dams form freely each winter on your roof? Are your shingles missing or cracked? Is your roof over 20 years old? If you answered yes to any of these questions, then it’s important to contact a reliable roofing contractor and have your roof inspected. You may need some minor repairs, or it may be time to plan ahead for a roof replacement. The better you maintain your roof, the longer it will last. 

4. What Type of Asphalt Shingles You Have on Your Roof

There are three basic types of asphalt shingles. The kind you choose will directly impact the lifespan of your roof. 
  • 3-Tab Shingles - These affordable, basic shingles last up to 20 years in locations with mild-moderate weather. They are not the best choice for harsh Minnesota winters. 
  • Dimensional Shingles - Also known as architectural shingles, these are made of durable fiberglass and a thin layer of asphalt, giving them a three-dimensional look. They last up to 25 years in most climates. 
  • Luxury Shingles - Premium asphalt shingles last up to 30 years on average, are plusher in their appearance, and are ideal for high-end homes. 

5. The Quality of Your Current Roof’s Installation 

The workmanship that went into your current roof’s installation is a major factor in how long your roof will last. Improper installation techniques can dramatically decrease a roof’s lifespan and lead to the need for early replacement. The bottom line is—if you hire a company who doesn’t install roofing according to the manufacturer’s guidelines and with attention to detail, it will cost you. 

6. Slope

Water is your roof’s enemy, so it’s vital that your roof drains properly. Poor drainage leads to more frequent roof repairs and earlier replacement. Your roof’s slope and pitch impact its drainage capabilities. Flat roofs and low slants yield more water accumulation, mold, fungus, and roof leaks—which lead to earlier roof replacement. 

7. Underlayment 

The waterproofing protection under your asphalt shingles provides an additional layer of defense against moisture intrusion. It safeguards your home from water penetration, mold, rot, and deterioration. Without a well-manufactured underlayment, the lifespan of your asphalt shingles will decrease. If your underlayment was not installed properly, your roof’s longevity will suffer. 

How to Prolong the Life of Your Roof

Contribute to the longevity of your roof with the following maintenance tips: 

Regular Inspections

From the safety of the ground, inspect your roof each spring and fall, and after major storms. If anything looks concerning, contact a professional roofer so they can take a look. 

Timely Repairs

The longer you leave problems with your roof, the bigger (and more costly) they become. When you see an issue, address it. Get repairs done when issues are minor so they don’t become major. 

Gutter Cleaning

When debris fills gutters and keeps water from freely flowing through them and away from your home, your roof is at risk of moisture infiltration. Water that gets stopped up in gutters has to go somewhere, and your roof decking will likely be infiltrated. 

Proper Ventilation

If your attic is not properly ventilated, hot, moist air will become trapped in it. This can cause your roof to age prematurely from the inside out. Don’t put your roof at risk of problems by leaving adequate attic ventilation out of the equation when you have your roof replaced next.
