How to Choose the Best Asphalt Shingle for Wisconsin Roofs

After you've decided to replace your roof, a critical next step is choosing your shingle.

At Sun Vault Roofing, we offer several grades of shingles to choose from.

For most homes around Madison, the right choice is a mid-tier architectural shingle that is Class 3 impact-rated. While a Class 4 impact-rated shingle make senses when storm exposure or insurance changes the math.

How to Choose the Right Roof Shingle: Key Takeaways

• Mid-tier laminate shingles are the right choice for most homes. In our experience, about 45% of homeowners choose our Certainteed Landmark Pro option, because the jump up from standard Landmark is usually the smallest dollar decision in the whole project.

• All laminate quality options are genuinely good roofs. Landmark, Landmark Pro, and ClimateFlex are all CertainTeed lifetime-limited, Class A fire-rated, dual or multi-layer architectural shingles.

• The real upgrade decision is Class 4. NorthGate ClimateFlex is the only one of the three rated UL 2218 Class 4 for impact, and it uses SBS (rubberized) asphalt that stays flexible in cold and reduces likelihood of hail damage.

• Insurance can move the needle. Some Wisconsin carriers discount Class 4 roofs. This can change the math to a clear ROI move.

• How long you'll stay in the home matters as much as the roof itself. Time horizon, storm exposure, and curb appeal goals usually decide this faster than the spec sheet does.

What Actually Separates One Shingle From the Next?

Three qualities separate asphalt shingle quality tiers:

1. Impact resistance

2. Weight and appearance

3. How the asphalt behaves in cold

Everything else on the spec sheet is close to identical across CertainTeed's architectural line.

Once you know where to look, the choice gets simple:

• Impact rating tells you how the roof handles hail.

• Weight and layer count tell you how rich the roof looks and how it ages.

• Asphalt chemistry tells you how it survives a January cold snap and a July hailstorm.

Landmark, Landmark Pro, and ClimateFlex: What's the Real Difference?

Here is the honest breakdown, pulled straight from CertainTeed's published product specs.

Feature	Landmark	Landmark Pro	NorthGate ClimateFlex
Impact Rating	UL 2218 Class 3	UL 2218 Class 3	UL 2218 Class 4
Build	Dual-layer	Multi-layer (thicker)	SBS rubberized asphalt
Number of Color Options Available in the Madison Area	10	17	12
Algae Resistance	25-year StreakFighter	30-year StreakFighter	30-year StreakFighter
Best For	Budget-conscious, rentals, quick sales	Most homeowners	Storm exposure, cold weather, insurance discounts
Warranty	Lifetime Limited	Lifetime Limited	Lifetime Limited
Fire Rating	Class A	Class A	Class A
Wind Warranty	160 mph	160 mph	160 mph

Note: All three qualify for the 160 mph wind warranty since we install every roofing system using CertainTeed starter and hip-and-ridge accessories. Other contractors are often only able to offer a 110 mph warranty

Landmark asphalt shingles are a great budget option

A dual-layer architectural shingle, available in 10 colors for Madison area homeowners, is rated UL 2218 Class 3 for impact and comes with a 25-year StreakFighter algae-resistance warranty and a lifetime limited warranty. A strong, proven roof.

Landmark Pro asphalt shingles are the most-frequently selected option

The heavier sibling. Same Class 3 impact rating and lifetime warranty, but a thicker multi-layer build that throws deeper shadow lines and carries a longer 30-year StreakFighter warranty. It looks more dimensional on the roof and resists algae streaking five years longer on paper. Since it is the most popular choice, it also has the most extensive color palette (17 different colors for Madison-area homes).

NorthGate ClimateFlex are worth the upgrade in specific situations

This shingle, available in 12 different colors for Madison homeowners, is rated UL 2218 Class 4, the highest impact class for asphalt shingles, and built from SBS polymer-modified ("rubberized") asphalt that resists cracking in extreme cold and resists damage from hail impacts. Carries the same lifetime and 30-year StreakFighter coverage as the Pro, plus the impact rating the other two cannot match.

The Questions That Decide Your Shingle

You do not need to memorize spec sheets. Answer these questions honestly, and the shingle usually picks itself.

#	Question	Why It Matters
1	What's your budget for the whole project?	The shingle is often a meaningful slice of the total cost.
2	How much does curb appeal matter to you?	Pro and ClimateFlex read richer from the street than standard Landmark.
3	How long do you plan to stay?	A roof you'll own for 20 years justifies more than one you'll sell in three.
4	What's your storm and hail exposure?	Open lots, west-facing slopes, and past hail claims all push toward Class 4.
5	Will your insurer reward a Class 4 roof?	Many do. Make the phone call to find out.

When Each Shingle Is the Right Call

When Landmark Is the Right Call

Landmark makes sense when you want a quality CertainTeed roof at the most efficient price and your home isn't carrying extra storm risk.

Best fit for:

• Rental properties

• Sellers who want a clean, warrantied roof without paying for upgrades the next owner captures

• Budget-driven projects where every dollar is allocated

If a contractor tries to make you feel bad about choosing it, find a different contractor.

When Landmark Pro Is the Natural Upgrade

Landmark Pro is the most-chosen option on our estimates (about 45% of homeowners), and the reason is almost always price. The step up from Landmark to Landmark Pro is usually the smallest upgrade decision in the entire project, sometimes a couple hundred dollars on a roof that costs many thousands.

For that, you get:

• A richer, more dimensional shingle

• Thicker build for stronger protection

• An extra five years of algae-streak protection

Spread across the 30-plus years you'll own the roof, the math gets easy in a hurry. This is the choice we see homeowners making most often. If curb appeal matters even a little, and the Pro delta on your estimate is small (ask us to show it side by side), Pro is the path of least regret.

When NorthGate ClimateFlex Earns the Premium

NorthGate ClimateFlex class 4 shingle is the real upgrade decision. It is the only option that costs meaningfully more, and the only one that changes how your roof survives a bad hailstorm. About 25% of our customers choose it.

Class 4 shingles we installed on Madison's east side in fall 2025. When baseball-sized hail hit the neighborhood on April 14, 2026, many surrounding homes had damage. This roof did not.

Class 4 shingles earn the premium in three situations:

1. Storm exposure: If your home sits on an open lot, faces frequent west-side weather, or has taken hail before, Class 4 impact resistance is extra valuable.

2. Cold-weather performance: The SBS rubberized asphalt stays flexible when standard shingles get brittle, which matters in a windy Wisconsin February.

3. Insurance discounts: Many carriers offer premium discounts for Class 4 roofs, which can offset part of the upgrade over time.

   
   

Important note: Class 4 is not hail-proof. Severe hail can still damage roofs, siding, skylights, and solar. What Class 4 buys you is better odds against the moderate hail Wisconsin actually sees most years. We break the full insurance and ROI picture down in our companion guide, Are Class 4 Shingles Worth It in Wisconsin?

Asphalt shingles are just one of the commonly-used roofing material options. But they are the option that makes the most sense for most situations on Wisconsin homes. Some roofing companies that are very good at marketing may try to convince you that you should buy a metal roof for 3x the price.

But metal roofs are a poor choice for most Wisconsin homeowners. If you are excited by a premium roof, Class 4 Architectural Asphalt shingles are worth a look. Or even an integrated solar roof with solar shingles.

When This Advice Doesn't Apply

A few situations flip the usual logic:

• Selling within 2–3 years: The case for any upgrade weakens because the next owner captures most of the long-term value.

• Roofing a rental: Standard Landmark usually pencils out better.

• Considering solar: A solar roof (like CertainTeed Solstice shingles) integrates power generation into the roof itself, and the shingle-series question becomes secondary to the system design.

• Recent storm or hail damage: The first call isn't about which shingle to buy. It's about documenting the damage properly for your claim. Get that right first, and the shingle decision follows.

Bottom Line: Pick the Shingle That Fits Your Home

There is no single right answer for every Wisconsin homeowner, but there is a right answer for yours. If you want a proven, quality roof at the most efficient price, Landmark delivers. If curb appeal matters and the upgrade cost is small, Landmark Pro is the easy call, and the one most of our customers make. If your home faces real storm exposure, brutal winters, or an insurer that rewards impact resistance, NorthGate ClimateFlex earns every dollar.

What matters most isn't the shingle series on the label. It's getting the right product installed correctly, with the right flashing, ventilation, and underlayment, by a crew that stands behind the work. That's where a roof actually wins or loses.

If you're still weighing your options, get the numbers in front of you.

Frequently Asked Questions

1. Which CertainTeed shingle is best for Wisconsin?

For most Wisconsin homeowners, Landmark Pro hits the best balance of looks, durability, and price. If you have real hail or storm exposure (or an insurer that rewards Class 4), NorthGate ClimateFlex is the stronger long-term call.

2. Is Landmark Pro worth it over standard Landmark?

Usually, yes. The price difference is often small relative to the total project, and you get a heavier, more dimensional shingle with five extra years of algae protection. We'll show you the exact dollar difference on your estimate so you can decide.

3. Is NorthGate ClimateFlex the same as Landmark?

No. ClimateFlex is built on a Landmark-style design but uses SBS rubberized asphalt and is rated UL 2218 Class 4 for impact, the highest class for asphalt shingles. Landmark and Landmark Pro are both rated Class 3.

4. Will a Class 4 roof lower my insurance in Wisconsin?

Sometimes. Some Wisconsin carriers offer discounts for impact-resistant roofs, and others offer little or none. Call your agent before you decide, because the answer varies by company and policy.

5. Do better shingles mean a better roof?

Only partly. The shingle matters, but installation quality, flashing, ventilation, and underlayment matter just as much. A premium shingle installed poorly underperforms a standard shingle installed right.
