When it is time for a new roof, you will need to choose between standard three-tab shingles and architectural (also called dimensional or laminated) shingles. Both are asphalt-based, but that is where the similarities end.
Three-tab shingles.
These are the flat, uniform shingles that have been the standard for decades. Each shingle has three tabs of equal size, giving the roof a consistent, clean look. They are lighter, thinner, and less expensive. A typical three-tab shingle carries a 20 to 25-year rating.
Architectural shingles.
These are thicker, heavier, and made of multiple layers bonded together. They create a dimensional, textured look that mimics wood shakes or slate. They hold up better in wind, resist impact better, and typically carry a 30 to 50-year rating. They cost more upfront, but they last significantly longer.
In our climate.
We are in the heart of Canadian freeze-thaw country. Architectural shingles handle the expansion and contraction better than three-tab because they are thicker and more rigid. They also resist wind uplift better, which matters when a February storm comes through.
The cost difference.
Architectural shingles typically cost 20 to 30 percent more than three-tab for materials. But most of the cost of a roof job is labour, and the labour is the same either way. When you factor in the longer lifespan, architectural shingles often cost less per year of service.
Our recommendation.
For most homeowners in the Waterloo Region, architectural shingles are the better value. The upfront cost difference is modest, and you get a better-looking, longer-lasting roof. We install both and we will walk you through the options for your specific home and budget.
