How Long Do Asphalt Shingles Last in Manitoba?

When it comes to roofing choices in Manitoba, asphalt shingles remain one of the most popular and practical options for both residential and commercial properties. They’re affordable, versatile, and well-suited to our climate. But how long can you really expect an asphalt shingle roof to last in Manitoba? What can you do to enhance its durability? Let’s break it down.

How Asphalt Shingles Are Made

Asphalt shingles are made from a fibreglass mat that’s coated with asphalt and topped with mineral granules. The fibreglass provides strength and fire resistance, the asphalt adds waterproofing, and the granules protect against UV rays while adding colour and texture.

This layered design is what makes asphalt shingles durable yet flexible, an important quality in a region like Southern Manitoba, where roofs must handle temperature swings, snow loads, and strong winds throughout the year.

How Long Do Asphalt Shingles Last in Manitoba?

On average, asphalt shingles last between 20 and 30 years. However, in Manitoba’s challenging climate, the true lifespan often depends on several key factors.

Climate and Weather Conditions

Manitoba roofs endure harsh winters, heavy snow, ice dams, freeze-thaw cycles, and summer heat. Extreme temperature fluctuations can cause shingles to expand and contract, which gradually breaks down the asphalt over time. Wind-driven rain and hail can also accelerate wear.

High-quality asphalt shingles, when properly installed, are designed to handle these conditions, but climate will always play a role in longevity.

Shingle Quality and Type

Not all asphalt shingles are created equal. Architectural or laminated shingles typically last longer than basic 3-tab shingles because they are thicker and more durable. Choosing a quality product from a trusted manufacturer can add years to your roof’s lifespan.

Installation Matters

Even the best materials won’t perform well if they aren’t installed correctly. Proper fastening, ventilation, underlayment, and flashing all impact on how long your roof will last. As certified installers, Advance Exteriors ensures your asphalt shingle roof is installed to manufacturer specifications, helping protect your investment.

Maintenance and Repairs

Routine inspections and timely repairs can significantly extend the life of an asphalt shingle roof. Addressing damaged shingles and blocked gutters before they become bigger problems can make a real difference.

How to Enhance the Durability of Your Asphalt Shingle Roof

With a little proactive care, you can get the most out of your asphalt shingles:

• Schedule regular roof inspections, especially after major storms

• Ensure attic ventilation is properly balanced

• Keep eaves and gutters clear of debris

• Repair damaged or missing shingles promptly

• Address ice damming issues early

These simple steps help reduce moisture buildup, prevent premature wear, and extend roof performance.
