Architectural shingles are worth it on almost every Michigan home. A 3-tab shingle is a single flat layer warranted to 60 mph for 25 to 30 years; an architectural shingle is a laminated two-layer product warranted to 110 to 130 mph for the lifetime of the original owner, and on a typical roof the installed price gap is small because the labor, tear-off, underlayment and flashing cost the same either way. We rarely install 3-tab anymore, and this article explains why, when it still makes sense, and what the manufacturers actually promise for each. Written by Aaron Scott, licensed Michigan residential builder and owner of Roofing Army.
What is the difference between 3-tab and architectural shingles?
A 3-tab shingle is one layer of fiberglass mat, asphalt and granules, cut with two slots so each strip reads as three flat rectangles. Every tab is the same size and the roof looks like a grid. An architectural shingle (also called dimensional or laminated) bonds a second layer of tabs onto a full base strip. The extra layer makes it thicker and heavier, gives it a random shadow pattern that hides roof imperfections, and, more importantly, gives the nail more material to hold onto.
Every roof in our job gallery is architectural. The Atlas Pinnacle Pristine and CertainTeed Landmark roofs you see there are the two products we quote most, and we compare them head to head with GAF Timberline HDZ in a separate article.
How long do 3-tab shingles last in Michigan?
Manufacturers warrant 3-tab shingles for 25 to 30 years. Atlas warrants its GlassMaster 3-tab for 30 years; CertainTeed's XT 25 carries a 25-year limited warranty. Those are warranty periods, not lifespans, and they are prorated after the first few years.
On the roofs we tear off in Ferndale, Royal Oak and Berkley, where 1950s and 60s ranches were often reroofed with 3-tab in the 2000s, the pattern is consistent: tabs curling and cracking at 15 to 18 years, granule loss in the gutters, and blown-off tabs after any strong spring storm on the roofs with poor attic ventilation. A well-installed architectural roof over a properly vented attic in the same neighborhoods is a 25 to 30 year roof, and that is the figure we use on our roof replacement page. The lighter, single-layer shingle simply has less asphalt to weather away and less material gripping each nail, and Michigan's freeze and thaw cycle punishes both.
How do the wind ratings compare?
This is the biggest performance gap, and it is written into the manufacturer warranties:
- Atlas GlassMaster (3-tab): Atlas's warranty schedule lists wind coverage of 60 mph with four nails, for a wind warranty length of five years.
- CertainTeed XT 25 (3-tab): CertainTeed lists a 5-year, 60 mph wind-resistance warranty.
- Atlas Pinnacle Pristine (architectural): 130 mph with a standard four-nail installation, per Atlas.
- CertainTeed Landmark (architectural): a 15-year, 110 mph wind-resistance warranty standard, with an upgrade to 160 mph available when CertainTeed starter and hip and ridge are used.
- Owens Corning TruDefinition Duration (architectural): a 130 mph wind resistance limited warranty with only four nails, per Owens Corning's data sheet.
The National Weather Service issues a severe thunderstorm warning at gusts of 58 mph, so a 3-tab roof is warranted only to roughly the threshold of an ordinary severe storm, and only for five years. That alone is enough for us to steer nearly every homeowner to a laminated shingle. If your roof has already lost tabs, our storm damage page covers how to document it for a claim.
How much more do architectural shingles cost?
Less than most people assume, because the shingle is a minority of the invoice. Tear-off, dump fees, decking repairs, ice and water shield, underlayment, drip edge, flashing, ventilation, permits and labor are identical whether the crew is laying 3-tab or architectural. The only line that changes is the shingle bundle price, and the labor is roughly the same because architectural shingles cover the same area per bundle with fewer, larger pieces.
We do not have a published 3-tab job to show you, because we have not installed one in years. What we can show you is what a full architectural roof actually costs here: 26 West Street in Oxford, a 1,440 square foot roof in Atlas Pinnacle Pristine Black Shadow, was $11,904.27, and 2251 Columbia Road in Berkley, 1,567 square feet in the same shingle, was $13,968.47. Both are complete tear-offs with 6 feet of ice and water shield at the eaves and a 50-year workmanship warranty. When a homeowner asks us to price 3-tab against those, the savings on the shingle line are not enough to justify giving up 70 mph of wind coverage and the lifetime warranty, and we say so.

3-tab vs architectural shingles: side by side
| Factor | 3-tab | Architectural |
|---|---|---|
| Construction | Single layer, flat, uniform tabs | Two laminated layers, random dimensional pattern |
| Manufacturer warranty | 25 to 30 years, prorated (Atlas GlassMaster 30, CertainTeed XT 25) | Lifetime limited for the original owner (Atlas Pinnacle Pristine, CertainTeed Landmark, GAF Timberline HDZ, OC Duration) |
| Wind warranty | 60 mph (Atlas GlassMaster and CertainTeed XT 25, five years) | 110 to 130 mph standard; higher with manufacturer accessories |
| Algae warranty | 10 years (CertainTeed XT 25) | 25 years to lifetime depending on brand |
| What we see at tear-off | Curling and cracking at 15 to 18 years | 25 to 30 years with good ventilation |
| Hides deck imperfections | No, flat surface telegraphs every wave | Yes, shadow lines mask minor unevenness |
| Installed cost difference | Shingle line only; labor, tear-off, underlayment, flashing and permits are the same | |
When does 3-tab still make sense?
There are a few honest cases, and we will quote 3-tab without argument in any of them:
- Matching an existing 3-tab roof on a small section. If a detached garage or a porch roof needs replacing and the house is staying 3-tab for now, matching the look can be the right call. Keep the Michigan Residential Code's 25 percent rule in mind, which we cover in our repair or replace guide.
- Sheds and outbuildings where wind exposure is low, the structure is not heated, and nobody is going to be under it during a storm.
- A property you are selling or leasing within a couple of years where the buyer or tenant is not paying for lifespan. Even here, we would show you the architectural number first, because the gap is usually smaller than the price reduction a buyer's inspector will ask for on a 3-tab roof.
- Historic district requirements. Rare, but some review boards specify a flat shingle profile.
What is not on that list: "the budget is tight." If cost is the constraint, the better lever is one of our five packages at different price points, or financing the roof, rather than downgrading the one component you cannot change later without another tear-off.
Why we rarely install 3-tab anymore
Three reasons, in order. First, the wind numbers above; we are the ones who get the call after a storm, and we do not want to install a roof we expect to see tabs from in the yard. Second, the warranty math: our 50-year workmanship warranty (see the warranty page) is meant to sit on top of a lifetime material warranty, not a 25-year prorated one. Third, resale: in our experience, inspection reports on Oakland and Macomb County homes flag a 3-tab roof as near end-of-life years earlier than an architectural roof of the same age, and buyers negotiate against it.
If you want both options priced, ask. Every quote we produce is line by line, with no deposit and a project manager on site on install day, and you can compare the shingle line yourself. Most homeowners look at the difference and pick the roof that will still be on the house in 2050.

Frequently Asked Questions
Are 3-tab shingles still made?
Yes. Atlas GlassMaster, CertainTeed XT 25 and Owens Corning Supreme are all current 3-tab lines. Their market share has fallen steadily because architectural shingles carry lifetime warranties and much higher wind ratings for a small increase in the shingle line of the invoice.
Can you put architectural shingles over 3-tab?
The Michigan Residential Code allows a second layer of asphalt shingles in some cases, but we do not recommend it. A layover hides rotted decking, adds weight, shortens the life of the new roof and voids the ice and water shield protection the code requires at the eaves. Every roof we replace is a full tear-off to the deck.
Do 3-tab shingles blow off more easily?
Yes. A 3-tab shingle has a single layer for the nail to grip and a warranted wind rating of 60 mph from Atlas and CertainTeed. Architectural shingles from Atlas and Owens Corning are warranted to 130 mph with a standard four-nail install, and CertainTeed Landmark to 110 mph standard. Southeast Michigan regularly sees gusts above 60 mph.
Is the price difference between 3-tab and architectural worth it?
Almost always. Tear-off, underlayment, ice and water shield, flashing, ventilation, permits and labor cost the same for both, so only the shingle line changes. For that difference you move from a 25 to 30 year prorated warranty at 60 mph to a lifetime warranty at 110 to 130 mph, plus a roof that lasts roughly ten years longer in our experience.
How long does an architectural shingle roof last in Michigan?
With correct installation and a properly ventilated attic, 25 to 30 years is a realistic expectation for an architectural asphalt roof in Southeast Michigan. Poor ventilation, missed nailing zones and skimpy ice and water coverage shorten that, which is why the installation matters as much as the shingle.
