Asphalt Shingle Installation — The Right Material, Installed the Right Way

But here's the detail many homeowners learn the hard way: the quality of a shingle installation depends as much on the workmanship as on the material. A premium shingle installed poorly won't outlast an ordinary shingle installed right.

At Deluxe Group, we've been installing asphalt shingles for over 15 years. We know the nuances of the trade, the common mistakes to avoid, and what it takes to make sure your roof stands the test of time for decades.

What a professional asphalt shingle installation involves

A complete installation is a precise sequence of steps — not just nailing rows of shingles and hoping for the best.

Here's what a job done right includes:

• Preparation and free inspection full inspection of the existing roof deck replacement Replacement of damaged plywood or OSB sections
• Installation of a bituminous or synthetic underlayment over the entire surface
• Ice & Water Shield membrane installed in critical zones — roof edges, valleys, around penetrations
• Asphalt shingles installed to manufacturer specifications and industry best practices — overlap, nailing, alignment
• Faucet Metal flashing — chimney, skylights, adjacent walls
• Ventilated ridge caps and rake-edge shingles
• Sealing and caulking of all junctions and penetrations
• Complete site cleanup at the end of the job

Every step matters. A poorly installed Ice & Water Shield membrane at the roof edge means ice dams seeping in on the first winter. Incorrect nailing on shingles means guaranteed blow-offs after the first strong wind.

Types of asphalt shingles — which ones to choose?

Not all shingles are created equal. The product you choose directly affects the durability, appearance, and value of your home.

3-tab shingles — the entry-level option The classic. Flat, uniform, with an estimated lifespan of 20–25 years in Quebec conditions. A good choice for a tight budget, but increasingly rare in new installations.

Architectural shingles — the current standard Thicker, with a dimensional profile and better wind and weather resistance. Lifespan of 25 to 35 years depending on quality. This is what we recommend for most residential projects: the value-to-durability-to-price ratio is clearly superior.

Premium shingles — maximum performance Engineered for enhanced resistance to high winds, hail, and freeze-thaw cycles. Manufacturer warranties up to 40 years and beyond. Ideal for complex roofs, high-value homes, or areas more exposed to the elements.

We'll help you choose the right product based on your budget, your home's age, and your priorities. No pushy upselling if it's not needed.

What Quebec's climate demands from a shingle installation

Quebec isn't exactly a gentle environment for a roof. Our climate conditions are among the most demanding in North America for this type of covering.

In winter: snow accumulation, repeated freeze-thaw cycles, ice dams at the edges. In spring: rapid thaw, heavy rains, major temperature swings. In summer: intense heat, UV rays that degrade granules, thunderstorms with hail. In fall: strong winds, debris, sudden cold snaps.

Each season tests your roof differently. That's why the installation has to account for these realities: proper membrane, proper attic ventilation, well-sealed flashing, and adapted nailing. This isn't a Florida installation replicated here — it's an installation designed for Quebec.

Frequently Asked Questions: Asphalt Shingle Installation

How long do asphalt shingles last in Quebec? 

Under Quebec conditions, a standard-quality architectural shingle lasts between 25 and 35 years with proper installation. Budget-friendly 3-tab shingles typically hold up for 20 to 25 years. Factors that affect lifespan: attic ventilation quality, wind exposure, quality of the original installation, and regular maintenance.

What's the difference between architectural shingles and 3-tab shingles? 

Architectural shingles are thicker, have a dimensional profile that mimics slate, and offer better resistance to wind and freeze-thaw cycles. They last longer and look noticeably more modern. For the vast majority of homes, this is the option we recommend.

Does the roof deck need to be replaced during a new installation? 

Not necessarily in its entirety — it depends on the condition of the wood. We systematically inspect the deck when removing the old shingles. Any rotted, warped, or sagging sections are replaced. It's a step we never skip — putting new shingles over a compromised deck is like building on a weak foundation.

Can shingles be installed in the fall or spring? 

Yes, in both cases, as long as weather conditions are right. Asphalt shingles require minimum temperatures of around 5°C for proper adhesion of the self-sealing strips. We always schedule installations with short-term weather forecasts in mind.

How long does a full installation take? 

For a standard single-family home, a complete installation typically takes 1 to 2 days. A more complex roof with multiple slopes, chimneys, or skylights may need an extra day. We'll give you the exact timeline in your free estimate.

Are asphalt shingles covered by a warranty? 

Yes — manufacturers offer warranties that vary by product, generally 25 to 50 years on materials. These warranties apply provided the installation is done to the manufacturer's standards, which we always follow. Labor is also covered by our own workmanship warranty.
