We Almost Learned This the Hard Way

One of the first roofs Johnny and I did after we started Dads Roofing in 2021 was a re-roof on a bungalow out near Rosedale. The homeowner wanted 3-tab. He had a number from another crew, and 3-tab was all that fit his budget. We installed it clean — six nails per shingle, proper staggering, everything by the book.

Fourteen months later, he called us back. A November outflow wind had peeled a 10-foot strip right off the south face. The shingles were fine — no manufacturing defect, no installation error. They just could not hold on in the kind of gusts that funnel through the Fraser Canyon. We repaired it at cost because it felt wrong to charge full price, and we told him straight: if we had done architectural shingles up front, those shingles would still be there.

That job is why we stopped recommending 3-tab for anything but rentals. Here is everything we have learned about these two shingle types across 500+ roofs in the Fraser Valley.

What Actually Makes Them Different

Both types are asphalt shingles. They both use a fibreglass mat coated in asphalt with ceramic granules on top. The difference comes down to construction.

3-tab shingles are a single layer of material cut into three tabs. They lay flat, they look uniform, and they have been the default residential shingle since the 1960s. Think of them as the base model.

Architectural shingles (also called dimensional or laminated) have two or three layers bonded together in a staggered pattern. This creates a textured, three-dimensional appearance that mimics cedar shake or slate. They are thicker, heavier, and the laminated construction makes them significantly tougher.

The easiest way to tell them apart from the ground: if your roof looks flat and repetitive, it is probably 3-tab. If it has depth, shadow lines, and varied colour tones, it is architectural.

Side-by-Side: The Numbers That Matter

Why the Fraser Valley Punishes Cheap Shingles

If you live anywhere between Hope and Abbotsford, your roof deals with conditions that most of southern Canada does not. We get 1,500-1,700mm of rain per year in the valley floor, and places like Agassiz and Harrison can see over 2,000mm. That is not a light misting — it is sustained, heavy rainfall from October through April.

On top of the rain, the Fraser Canyon funnels outflow winds that regularly hit 80-120 km/h. Johnny and I have been on roofs near Bridal Falls when the wind shifted and went from calm to 90 km/h in ten minutes. Those gusts do not care about your shingle warranty — they care about physics.

Here is what that means for each shingle type:

3-tab in the Fraser Valley: The single-layer construction sits flat, which sounds fine until water pools in the tab slots during extended rain. The lighter weight (200-250 lbs per square) gives them less holding power in wind. Their 60-70 mph wind rating is below the gusts we regularly see in the eastern valley. The thin profile also makes them more vulnerable to moss penetration — and moss is unavoidable here.

Architectural in the Fraser Valley: The multi-layer, staggered profile sheds water more efficiently because there are no flat tab slots for water to collect. The added weight (250-400 lbs per square) helps them grip the deck. Wind ratings of 110-130 mph give real margin against outflow events. The thicker profile resists moss root penetration better, though you still need maintenance.

The Real Cost Calculation Most Roofers Skip

Every quote you get will compare the upfront cost. That is the wrong comparison. Here is how the math actually works for a typical 25-square roof in the Fraser Valley (2026 pricing):

Upfront Cost

• Architectural, installed: approximately $11,500-$13,000
• 3-tab, installed: approximately $9,500-$11,000
• Difference: $1,500-$2,000 more for architectural

That $1,500-$2,000 is the number most people focus on. But a roof is not a one-time purchase — it is something your house needs for as long as you own it.

Over 30 Years

• Architectural: One roof, 25-30 year lifespan. Total cost: $11,500-$13,000.
• 3-tab: One roof at year 0, one replacement at year 15-18. Total cost: $19,000-$22,000 (original + replacement at inflated prices).

The "cheaper" shingle costs you $7,000-$9,000 more over the life of the home. Johnny puts it this way: "Paying less now to pay more later is not saving money. It is borrowing from yourself at a bad rate."

When 3-Tab Still Makes Sense

We are not going to pretend 3-tab is never the right call. There are a few situations where it genuinely fits:

• Rental properties where appearance is irrelevant — if your tenant does not care and you are managing cash flow across multiple properties, the upfront savings can matter.
• You are selling within a year or two — a new 3-tab roof still looks clean and passes inspection. If you are listing in spring, 3-tab gets the job done.
• Matching an existing 3-tab section — if you are replacing one slope and the rest is 3-tab that still has 10 years of life, matching is practical. Though we will warn you: finding matching 3-tab profiles is getting harder every year as manufacturers phase them out.
• Truly fixed budget with no flexibility — when $1,500 is the difference between getting a new roof this year and waiting another winter with leaks, function beats aesthetics.

The Disappearing 3-Tab Market

Something most homeowners do not realize: 3-tab shingles are being phased out. IKO, CertainTeed, and BP have all shrunk their 3-tab product lines over the past five years. Colour options are limited. Some profiles are discontinued entirely.

This creates a practical problem. If a tree branch damages a section of your 3-tab roof in 2030, there is a real chance you will not be able to find matching shingles. That means replacing the entire visible slope instead of patching a small area — which erases most of the upfront savings you thought you got.

We keep some 3-tab stock at our yard in Agassiz for patch jobs, but even we are seeing supply get thinner every year.

What We Install (and Why)

At Dads Roofing, roughly 95% of the roofs we install use architectural shingles. That is not because we make more money on them — the margin is similar either way. It is because after five years and 500+ roofs from Hope to Abbotsford, we have seen what lasts and what does not in Fraser Valley weather.

Johnny and I came from the Alberta oil sands where we worked as Red Seal Boilermakers. In that world, you do not cut corners on materials. You use what the spec calls for because failure means shutdown, injury, or worse. We brought that mindset to roofing. Every roof we install gets six nails per shingle (not four), proper ice and water shield at all vulnerable points, and we stay until every seam is watertight — even if that means working past dark.

When someone asks us what shingle to use, we tell them the truth: architectural is better in every way that matters for this climate. If budget is genuinely tight, we will install 3-tab and do it properly. But we will also be honest about what you are giving up.

Our Recommendation for Fraser Valley Homeowners

If you own your home and plan to live in it, go architectural. The extra $1,500-$2,000 upfront saves you a full re-roof 15 years from now. Your roof will handle the wind better, shed rain better, resist moss better, and look better doing it.
