Mastering Asphalt Roofing for Canadian Weather: A Comprehensive Guide

Canada, with its diverse climate ranging from the icy winters of the north to the humid summers in the south, presents unique challenges for homeowners. One crucial aspect that directly impacts the longevity and performance of homes in Canada is the choice of roofing material. In this comprehensive guide, we delve into the benefits of asphalt roofing, considering the specific weather conditions that Canadians face. From the frigid temperatures of the Arctic to the temperate climates in the south, asphalt roofing emerges as a versatile and reliable choice.

Understanding the Canadian Weather Landscape

  2. Rainy Springs: Spring is characterized by increased rainfall, and roofing must be able to efficiently drain water to prevent leaks and water damage.
  3. Hot Summers: Southern regions of Canada experience hot and humid summers, putting roofs to the test in terms of heat resistance and UV protection.
  4. Fall Leaves and Debris: During the fall, leaves and debris can accumulate on roofs, potentially leading to issues such as clogged gutters and water pooling.

Why Choose Asphalt Roofing?

  1. Durability in Cold Weather: Asphalt roofing excels in cold climates due to its flexibility. It can expand and contract with temperature variations, preventing cracking or damage caused by freezing and thawing cycles.
  2. Snow Shedding: The granular surface of asphalt shingles facilitates the shedding of snow, preventing the formation of ice dams. This is crucial in areas where heavy snowfall is common.

  5. Affordability: Asphalt roofing stands out as a cost-effective solution without compromising on quality. This makes it an attractive option for homeowners looking for durable roofing within a budget.
  6. Structuring Your Roofing Investment:
  7. When considering roofing options in Canada, it’s not just about choosing the material; it’s about making a long-term investment in your home’s protection and energy efficiency. Asphalt roofing, with its versatility and adaptability to various weather conditions, emerges as a top contender.
  8. Selecting the Right Asphalt Shingles:Start by choosing the right type of asphalt shingles. Three-tab shingles are a cost-effective option, while architectural shingles provide enhanced durability and aesthetic appeal. Consider your budget and the specific weather challenges your region faces.
  9. Understanding Roof Pitch:Roof pitch plays a crucial role in the effectiveness of asphalt roofing. Steeper pitches enhance water and snow shedding, preventing the accumulation of debris and potential water damage.

How to Install Asphalt Roofing

Installing asphalt shingles is a common and straightforward process that, when done correctly, provides a durable and weather-resistant roof. Here’s a step-by-step guide to help you through the installation process:

Materials and Tools:

  • Asphalt Shingles
  • Underlayment (Felt or Synthetic)
  • Drip Edge
  • Starter Strip Shingles
  • Roofing Nails
  • Roofing Adhesive
  • Flashing
  • Ventilation (if needed)
  • Hammer
  • Roofing Nailer
  • Utility Knife
  • Chalk Line
  • Tape Measure

When preparing to install new shingles, it’s common for individuals to overlook the aspect of disposing of the old shingles. Simplify this process by considering options such as renting a dumpster or a dumping trailer. This choice significantly streamlines the task of hauling away not just old shingles but also underlayment and other debris. Dumpster rentals often include both delivery and removal services, though additional charges may apply. If you possess a truck capable of towing a dumping trailer, a cost-effective alternative is to rent the trailer and handle the debris removal yourself.

Given that removing old shingles is inevitably a messy endeavor, it’s wise to lay down several tarps to facilitate the cleanup once the task is complete. A strategic placement of tarps ensures a smoother process; tossing old shingles off the roof becomes more efficient when you know the tarps will catch and contain the debris. This approach not only expedites the job but also eliminates the need for careful consideration about where each shingle is thrown during the removal process.

Step 1: Prepare the Roof

  1. Inspect the Deck:
    Before starting, ensure the roof deck is in good condition. Repair any damaged or rotten areas and replace any deteriorating sheathing.
  2. Install Drip Edge:
    Attach a drip edge along the eaves of the roof. This metal strip helps direct water away from the fascia and prevents water damage.
  3. Before you grab your ladder and begin attaching shingles to your roof, it’s essential to take some preliminary steps for a smoother process and avoid unnecessary trips to the hardware store. In addition to obtaining the right tools and materials, consider the following preparations.
  4. Firstly, pay attention to the weather forecast and select a clear day for your project. Attempting shingle installation in wet conditions is a recipe for problems, so it’s prudent to postpone the project by a week if there’s any chance of rain. Similarly, plan your roof work during temperate months to avoid extreme weather conditions. Exposure to scorching summer sun or biting winter winds is not ideal, and it’s crucial to recognize that there’s a temperature threshold that is too cold for roofing. While many opt for spring installations as the weather warms up, autumn is equally suitable, provided it’s done before your roof is covered with leaves.
  5. Given that installing shingles can be noisy, it’s considerate to inform your neighbors beforehand. Also, avoid starting work too early, as each step in the process generates noise. If you have noise-sensitive pets, it’s advisable to arrange for them to be away from the house on installation day if feasible.
  6. Lastly, as part of your preparation, clear both your front and back yards of anything that might be damaged by falling debris. This includes patio furniture, outdoor grills, and lawn decorations. By taking these preparatory measures, you set the stage for a more efficient and considerate shingle installation process.

Step 2: Install Underlayment/Lay Underlayment:

Roll out the underlayment (either felt or synthetic) from the bottom of the roof, overlapping each row by about 6 inches. Staple or nail the underlayment in place. our roof is almost ready to get to work, but before you do, you need to take some careful measurements, so you know how many shingles to buy and how much underlayment you need.

To estimate the number of shingles you need, measure the length and the width of each independent section of your roof. Multiply the length by the width to get the area (this is usually measured in square feet). In roofing parlance, the total square footage of your roof is usually divided by 100 to get a measurement called “squares.” You’ll need the size of your roof in squares to know how many shingles you need to buy.

As an example, if the main section of your roof measures 40 feet by 50 feet, the area is 2,000 square feet, which equals 2,000 ÷ 100 = 20 squares.

Shingles — and other roofing supplies — are usually sold in bundles, with three bundles of shingles covering approximately 20 squares. If you want to avoid repeated trips to the store, round up the number of shingle bundles you need by one or two. Having extra shingles on hand is never a bad idea and you can always return unopened bundles leftover when you’re finished.

Thankfully, felt paper is also sold in terms of squares, so you won’t need to do any more math to figure out how much you need. If you’re confused, don’t hesitate to ask someone at the hardware store. If you tell them how big your roof is, they’ll be able to help you figure out what you need.

Step 3: Install Starter Strip Shingles

Install a row of starter strip shingles along the eaves. These shingles have a sealant strip that bond with the first row of full-sized shingles. Before you start putting shingles on your roof, there are a few crucial steps you need to take. If you’re new to roofing, it might surprise you that there are things to install before those shingles go on.

    Drip Edge:

    Let’s talk about drip edges. They’re vital for any roof. Because water has this tendency to stick to your roof when it rains, a drip edge is a must. Without it, water can sneak under your roof’s edge, causing leaks and damage over time. You’ve got to get that drip edge on before the shingles. It sits on the fascia board, and you want it close but not touching the edge. Leave about a half-inch gap between the bottom of the drip edge and the fascia board. Nail it down with 1–1/4–inch roofing nails. No need to be super precise here. Don’t forget to put drip edges on the gable ends too; follow the same process.

    Felt Paper:

    Now, before those shingles go down, you’ve got to cover the roof with felt paper. The usual choice is the standard 30-pound felt paper, good for most climates. The felt paper’s job is to create a buffer between the shingles and the roof sheathing. This is crucial so that your roof and shingles can expand and contract independently when the temperature changes. If you skip the felt paper, your shingles might get stuck to your roof and lose flexibility when the weather shifts. Felt paper also helps absorb any condensation that might form under your shingles. Nail down the felt paper with the same roofing nails you used for the drip edges. Precision isn’t a must here; just make sure the felt lies flat against the roof with no ridges or folds.

    Roofers might have different ways of doing this, but many find that laying out the felt in overlapping rows is the easiest. Aim for half-overlapping strips, laying the paper across the long side of your roof, parallel to your gutter. It’s generally better to have a bit more overlap than less. You want to avoid any spots where your shingles touch your roof directly.


    Now, flashing is another thing to consider. If the flashing around your chimney and vents looks worn or damaged, you might need to replace it. But often, you can reuse the current flashing. Just be careful when removing shingles around your chimney, skylights, vents, and siding to avoid damaging the flashing. If it’s in good shape, set it aside for later use.

    Step 4: Install Asphalt Shingles

    Mark Reference Lines:
    Use a chalk line to mark horizontal reference lines on the roof to ensure straight and even shingle installation.

    Begin First Row:
    Start at the bottom edge of the roof and place the first shingle with the tabs facing up. Nail it in place, following the manufacturer’s recommendations for nail placement.

    Continue First Row:
    Continue adding shingles along the first row, making sure to maintain a consistent overhang and using the sealant strips.

    Start Second Row:
    For the second row, start with a half shingle to offset the seams from the first row. Stagger the shingles to avoid vertical seams lining up.

    Continue installing rows of shingles, staggering the seams and nailing according to manufacturer guidelines. Use a roofing nailer for efficiency.

    Install Flashing: Install flashing around roof penetrations (vents, chimneys) and in valleys. Secure the flashing with roofing cement or adhesive.

    Step 5: Complete Roofing & Clean Up

    Trim Shingles:
    Trim the last row of shingles as needed to fit. Use a utility knife to cut shingles to size.

    Install Ridge Shingles:
    Install ridge shingles along the peak of the roof. These shingles are specifically designed for this purpose and provide a finished look.

    Remove any debris from the roof and clean the gutters. Ensure that the roof is free of loose nails and materials. Read more: Unlocking the Secrets: The Ultimate Roof Installation Guide.

    Additional Tips:

    • Use Adhesive:
      Apply roofing adhesive under each shingle to enhance wind resistance, especially in areas prone to storms.
    • Check Ventilation:
      Ensure proper ventilation in the attic to prevent heat buildup, which can affect the longevity of the shingles.
    • Follow Manufacturer Guidelines:
      Always follow the specific guidelines provided by the shingle manufacturer for installation and warranty purposes. Read more: Replacing Old Shingles with New Shingle Installation
