Architectural Shingles

Discover the ideal roofing solution for Ottawa’s unique climate with architectural shingles. In this comprehensive guide, you’ll learn about their superior durability, weather resistance, and aesthetic versatility, making them a wise investment for long-term cost savings and enhanced curb appeal.


  • Superior Durability and Weather Resistance: Architectural shingles are designed with multiple layers of asphalt and fiberglass, making them highly durable and weather-resistant. They are suitable for Ottawa’s harsh winters and hot summers, withstanding heavy snowfall, intense UV rays, and high winds. Their lifespan can surpass 30 years, translating into long-term cost savings.
  • Aesthetic Versatility: These shingles offer a wide variety of styles, textures, colours, and patterns, allowing homeowners to enhance their home’s curb appeal. From mimicking natural materials like wood or slate to providing unique designs like scalloped edges or staggered patterns, architectural shingles can transform a roof into a work of art.
  • Energy Efficiency: Architectural shingles are known for their excellent insulation and energy-saving properties. Their laminated construction creates an air barrier, and reflective granules minimize heat absorption, reducing reliance on air conditioning and lowering energy bills. They are also available with different Energy Star ratings, reflecting a commitment to sustainability and eco-friendly options.
  • Insurance and Warranty Considerations: Architectural shingles often meet insurance requirements for durability and weather resistance, making them a wise choice from an insurance perspective. Reputable manufacturers provide extended warranties ranging from 20 to 50 years, safeguarding against defects or damage. Professional installation is crucial to maximize warranty coverage.
  • Top Choices for Ottawa’s Climate: Two leading options in architectural shingles for Ottawa’s climate are Owens Corning Architectural Shingles and GAF Architectural Shingles. Both are highly recommended for their exceptional weather protection, energy efficiency, and attractive design options. Owens Corning is particularly noted for its wind resistance, thanks to SureNail® Technology.


In Ottawa, a city known for its architectural beauty, architectural shingles play a vital role in the city’s landscape. These shingles, also referred to as dimensional or laminated shingles, are popular for residential roofing due to their aesthetic appeal and exceptional protection.

When selecting roofing material in Ottawa, considerations include aesthetics, budget, and climate. Given the unpredictable weather, investing in high-quality architectural shingles is essential. This article serves as a comprehensive guide on these shingles, discussing various styles, textures, energy efficiency ratings, durability, and lifespan.

Architectural shingles are an ideal choice for homeowners in Ottawa’s climate, offering a multitude of benefits. Their exceptional weather resistance is designed to withstand harsh Canadian winters, heavy snowfall, intense UV rays, and high winds.

Unlike traditional asphalt shingles, their thicker, multi-layered construction provides superior protection against moisture and leaks. They also boast greater durability, with a lifespan that can surpass 30 years, translating into long-term cost savings and often accompanied by generous warranties from reputable manufacturers.

Aesthetic versatility is another advantage, with a wide variety of styles, textures, colours, and patterns available to enhance a home’s curb appeal. Additionally, many architectural shingle products are energy-efficient, with reflective properties that reduce heat absorption and lower energy consumption for cooling during hot summers.

Architectural Shingles vs 3-Tab Shingles

Architectural shingles are a type of asphalt shingle that stands out from traditional 3 tab shingles in appearance and construction.

Unlike the uniform and flat profile of 3 tab shingles, architectural shingles mimic the look of expensive materials like slate or wood shake, giving a premium appearance that can enhance home value.

Their dual-layered construction, bonded with an adhesive strip, offers added protection against moisture and leaks, making them more resistant to wind uplift. This is especially important in Ottawa with the increase in severe wind and weather (credit @YOW_Weather on Twitter).

Unlike the basic shades of 3 tab shingles, architectural shingles come in a wide range of colours, offering flexibility in style, with manufacturers like Owen’s Corning and GAF providing numerous options.

Styles and Textures

Architectural shingles have revolutionized roofing aesthetics by offering a wide variety of styles and textures that add depth and character to homes. Gone are the days of dull, monotonous asphalt roofs.

Now, homeowners can choose from options like dimensional shingles, also known as laminate or architectural laminate shingles, which mimic the look of natural materials like wood or slate, adding an elegant and sophisticated touch.

For those who prefer a rustic charm, architectural shingles with a weathered or textured finish replicate the appearance of aged wood or weathered slate tiles, providing an authentic vintage feel.

Whether aiming for classic elegance or rustic charm, the numerous styles and textures of architectural shingles allow homeowners to find the perfect style to enhance both the aesthetics and value of their homes in Ottawa.

Energy Efficiency Ratings

In Ottawa’s climate, energy efficiency is a key consideration when choosing roofing material, and architectural shingles have become popular for their excellent insulation and energy-saving properties.

Designed with multiple layers and varying thicknesses, they offer better thermal resistance than traditional asphalt shingles. Their energy efficiency stems from their special laminated construction, which creates an air barrier, and the inclusion of reflective granules that minimize heat absorption.

This design helps keep living spaces cooler during hot summers, reducing reliance on air conditioning and lowering energy bills. Architectural shingles are also available with different Energy Star ratings, meeting EPA criteria for reducing greenhouse gas emissions.

Investing in these shingles not only leads to financial benefits but also reflects a commitment to sustainability and eco-friendly options. By improving insulation, homeowners can reduce their carbon footprint and conserve resources.

To maximize the energy-saving potential of architectural shingles, it’s advisable to consult professional roofing contractors and local suppliers in Ottawa, ensuring proper installation and guidance on the most suitable energy-efficient options for specific needs.

Durability and Lifespan

Architectural shingles are renowned for their exceptional durability and long lifespan, making them a preferred choice for homeowners in Ottawa. Unlike traditional asphalt shingles, architectural shingles are constructed with multiple layers, including a fiberglass mat core, asphalt, and granules.

This structure makes them sturdier and more resistant to wear and tear, enabling them to withstand Ottawa’s harsh weather conditions. The layered design also adds a distinctive visual appeal to homes.

With proper installation by experienced contractors, architectural shingles can last 25 to 30 years or more, saving homeowners from frequent replacement costs and providing peace of mind. Many manufacturers also offer generous warranties ranging from 20 to 50 years, adding further value and protection against defects or damage.

Compared to other roofing options, architectural shingles stand out for their superior performance in durability and aesthetics, and their pricing is considered reasonable given the numerous benefits.

Why Architectural Shingles Are Best for Ottawa’s Climate

Architectural shingles have gained popularity in Ottawa due to their outstanding durability, weather resistance, and suitability for the region’s diverse and often harsh weather conditions.

Ottawa’s strong winds, particularly during winter, necessitate roofing that can withstand gusty conditions, and architectural shingles meet this need with a unique interlocking design that prevents lifting or tearing.

This design also helps in shedding water and resisting leaks, protecting homes from water damage, a crucial feature in Ottawa’s climate with its heavy rainfall and snowmelt. Additionally, architectural shingles offer excellent insulation, with air pockets between layers acting as natural insulators, helping regulate indoor temperatures and reduce energy consumption.

Selection Guide

Selecting the right roofing material is a critical decision for homeowners in Ottawa, where the climate demands both durability and aesthetic appeal. Architectural shingles have emerged as a preferred choice, offering a blend of strength, energy efficiency, and design versatility.

Insurance and Warranty Considerations

When it comes to investing in a new roof, insurance and warranty considerations are crucial aspects to keep in mind. Let’s dive into why these factors are important and what you should look for when choosing architectural shingles for your Ottawa home.

Some policies may have specific requirements or limitations regarding the type of roofing materials that qualify for coverage.

Architectural shingles, with their reputation for durability and weather resistance, often meet these requirements, making them a wise choice from an insurance perspective. Furthermore, warranties ensure peace of mind by offering protection against potential defects or premature failure.

When researching insurance coverage and warranties available, consider reaching out to local roofing suppliers in Ottawa who can provide insights into which brands offer superior policies tailored to this region’s unique climate demands.
