IKO Cambridge: The Classic Choice

IKO Cambridge is the most widely used of the three, and for good reason. It’s a great all-around shingle that balances affordability with durability.

What They’re Made Of
Cambridge shingles are architectural asphalt shingles, meaning they have a layered look that adds dimension to your roof. They’re made with a fiberglass mat, asphalt, and ceramic-coated granules, which provide color and UV protection.

Lifespan and Durability
On average, Cambridge shingles last about 25 to 30 years with proper maintenance. While they don’t have the added reinforcements that the Dynasty and Nordic lines offer, they still hold up well against wind and normal weather conditions.

Cambridge shingles have a dimensional, high-end look that mimics wood shakes. They come in a variety of colors, so you can match your home’s style without any trouble.

Why Choose Cambridge?

  • Ideal if you want a budget-friendly, durable shingle
  • Great for homeowners who want a good-looking roof without overpaying for extra features
  • Works well in moderate climates without extreme storms or heavy impact concerns

If your main concern is getting a reliable, attractive roof at a reasonable price, Cambridge is a solid choice. It’s like the dependable family car—does the job well without unnecessary bells and whistles.

IKO Dynasty: A Step Up in Strength

IKO Dynasty shingles take everything Cambridge offers and add a layer of toughness. If you want a shingle that can handle heavier storms and stronger winds, this might be your best bet.

What They’re Made Of
Dynasty shingles are also asphalt-based with a fiberglass core, but they include IKO’s ArmourZone reinforcement, which provides extra tear resistance and durability.

Lifespan and Durability
You can expect Dynasty shingles to last around 30 to 35 years, thanks to their added reinforcement. They’re also rated for winds up to 130 mph, making them a great option for areas that get strong storms.

Appearance
Dynasty shingles offer a bolder, high-contrast look compared to Cambridge. The colors tend to pop more, and they give your home an upgraded, premium feel.

Why Choose Dynasty?

  • Excellent for homeowners who want extra durability and wind resistance
  • Ideal if you live in an area with frequent storms and high winds
  • Offers a stylish, high-end look without breaking the bank

Dynasty is like upgrading from a regular SUV to one with off-road capabilities. You might not need the extra strength every day, but when bad weather hits, you’ll be glad you have it.

IKO Nordic: The Heavy-Duty Option

IKO Nordic shingles are the toughest of the three. If you want a roof that can handle serious weather, this is the top-tier choice.

What They’re Made Of
Nordic shingles have all the features of Dynasty but with an added layer of impact-resistant material. They contain polymer-modified asphalt, which helps them absorb impacts from hail and debris.

Lifespan and Durability
These asphalt shingles can last 35 to 40 years, making them one of the longest-lasting options in the IKO lineup. They also have a Class 4 impact resistance rating, which is the highest in the industry. If your area gets hailstorms, this is the shingle you want.

Appearance
Nordic shingles have the same bold, high-contrast look as Dynasty, so they look just as premium but with extra durability.

Why Choose Nordic?

  • Perfect for homeowners in hail-prone or extreme weather areas
  • May qualify you for insurance discounts due to its high impact rating
  • Ideal if you want a long-lasting, high-performance roof

Think of Nordic shingles like a heavy-duty pickup truck with reinforced bumpers. It’s built to handle rough conditions and last a long time.

Which IKO Asphalt Shingles Are Best for You?

If you’re still unsure which one to choose, here’s a simple breakdown.

  • Cambridge: Best for budget-conscious homeowners who want a solid, attractive shingle without extra reinforcements
  • Dynasty: Great for those who need added wind resistance and durability, especially in storm-prone areas
  • Nordic: The best option for maximum protection against hail and extreme weather

Your choice depends on your budget, the climate in your area, and how long you want your roof to last. If you live in a place like Lake St. Louis, where storms can be unpredictable, going with Dynasty or Nordic might be a smart move.
