CertainTeed vs Malarkey
Shingles: Oklahoma Roof Comparison

Brand Overview

CertainTeed — Malvern, Pennsylvania. One of North America's largest and oldest roofing manufacturers, operating since 1904 and now part of the Saint-Gobain group. CertainTeed's Landmark series is among the best-selling architectural shingles in the country, and its Landmark Impact line adds serious storm protection in a rubberized-asphalt construction. Select CertainTeed shingles carry StreakFighter algae-resistance technology.

Malarkey — Portland, Oregon. A family-owned manufacturer that pioneered polymer-modified (SBS) asphalt shingles — the "rubberized" shingle category. Malarkey's Legacy shingle is its flagship Class 4 impact-resistant product, and Windsor is its architectural workhorse. Malarkey was the first manufacturer to offer 3M Scotchgard Protector algae resistance, and its shingles are known for flexibility, smog-reducing granules, and 130 mph wind warranties.

Both brands are premium choices for Oklahoma homeowners. This guide compares them side by side for hail, wind, algae, warranty, and price so you can choose with confidence — and we'll walk through why installation quality matters more than the logo on the shingle.

Side-by-Side Comparison

Product Lines Compared

CertainTeed Landmark & Landmark Impact

Landmark is the shingle that made CertainTeed famous — a two-piece architectural shingle with a deep shadow band that gives roofs a rich, dimensional look. It's available in dozens of color blends, carries a limited wind warranty up to 110 mph on most lines, and select colors include StreakFighter algae protection. For most Oklahoma homeowners, Landmark represents the reliable, best-selling standard.

Landmark Impact is the storm-rated version: a Class 4 impact rating under UL 2218, built with a rubberized asphalt blend that stays flexible in cold weather, plus reinforced granule adhesion so hail doesn't knock the protective granules off the mat. It's the CertainTeed product we most often recommend for Oklahoma's hail belt.

Malarkey Legacy & Windsor

Legacy is Malarkey's flagship — an SBS polymer-modified (rubberized) architectural shingle with a Class 4 impact rating, 3M Scotchgard Protector algae resistance, a 130 mph limited wind warranty, and smog-reducing granules. The SBS modification is the key: it makes the shingle act more like rubber than brittle asphalt, so it flexes instead of cracking when hail hits and seals tighter in Oklahoma's wild temperature swings.

Windsor brings most of that same technology — SBS modification, Scotchgard protection, and strong wind warranties — into a more accessible price point. If you want Malarkey's engineering without the Legacy premium, Windsor is the value pick.

Warranty Comparison

Both manufacturers offer lifetime limited warranties on their premium architectural lines — CertainTeed on Landmark and Landmark Impact, Malarkey on Legacy and Windsor. Coverage typically includes non-prorated replacement periods for manufacturing defects, with terms that vary by product line. Both require installation by a certified contractor and timely warranty registration to stay in force.

The warranty is only as good as the installer standing behind it. Proof Construction is a manufacturer-certified installer, which means your shingle warranty is registered correctly — and every project we install also carries our written 3-year workmanship warranty — 3x Oklahoma's 1-year minimum. A shingle warranty covers the product; our workmanship warranty covers the installation. You want both.

Hail & Wind Performance in Oklahoma

Oklahoma is one of the most hail-prone states in the country, and the Tulsa metro takes direct hits on a regular basis. When hail is the threat, Class 4 impact rating (UL 2218) is the single most important spec on the box — and both CertainTeed Landmark Impact and Malarkey Legacy carry it.

Here's how the two approaches differ: Malarkey's SBS polymer modification makes Legacy genuinely rubberized — it flexes under impact and resists cracking even in cold weather. CertainTeed's Landmark Impact uses a rubberized asphalt blend with superior granule adhesion, which keeps the protective surface intact when stones hammer the roof. Both are proven, both are excellent, and both qualify for the insurance premium discounts many Oklahoma carriers offer for Class 4 roofs.

Wind is the second threat. Oklahoma's spring storms routinely produce straight-line winds above 80 mph, and the state sees more than its share of tornadoes. Both brands offer limited wind warranties up to 110–130 mph on their premium lines, and both require proper installation — correct nailing pattern, proper nail placement, and sealed adhesive strips — to perform. That's why installation quality is the variable that separates a 10-year roof from a 30-year roof.

Algae Resistance: StreakFighter vs Scotchgard

Algae doesn't destroy an asphalt roof, but it does destroy its looks — those black streaks on north-facing slopes are blue-green algae feeding on limestone filler in the granules. Oklahoma's hot, humid summers and tree-shaded roofs make algae a genuine curb-appeal problem.

CertainTeed StreakFighter embeds copper-based granules into the shingle. As rainwater washes over the surface, copper ions suppress algae growth for the life of the shingle. Malarkey's 3M Scotchgard Protector does the same job with zinc technology — and Malarkey was the first manufacturer in the industry to offer it, so the technology has a long field-proven track record. Both are effective; the practical difference is copper vs zinc chemistry and which color blends carry the treatment. If your roof has heavy shade, ask us to spec an algae-resistant option from whichever brand you choose.

Price Comparison

In the Tulsa and Broken Arrow market, installed pricing looks like this (per square foot, materials + labor):

• CertainTeed Landmark / Malarkey Windsor (standard architectural): roughly $3.50–$5.00/sq ft — about $350–$500 per square (100 sq ft)
• CertainTeed Landmark Impact / Malarkey Legacy (Class 4 impact): roughly $5.00–$7.50/sq ft — about $500–$750 per square
• The real cost drivers: roof size and pitch, number of layers being torn off, decking condition, flashing and pipe boot replacement, ridge vent and attic ventilation upgrades

Between the two brands at the same performance tier, pricing is close — differences of a few percent are normal and often come down to color availability and distributor pricing in your area. The premium for Class 4 impact protection is the same story on both brands, and it's almost always worth it in Oklahoma: better hail survival, fewer claims, and insurance discounts. Every Proof Construction estimate is itemized with Xactimate line items, so you see exactly what you're paying for before you sign.

Which Shingle Should Oklahoma Homeowners Choose?

Choose Malarkey Legacy if you want maximum impact flexibility and an all-in-one storm package: SBS rubberized construction, Class 4 rating, 130 mph wind warranty, Scotchgard algae protection, and smog-reducing granules all on one shingle. It's the most technology-dense asphalt shingle on the market.

Choose CertainTeed Landmark (or Landmark Impact) if you want the best-selling architectural shingle in North America, the broadest color palette to match your home's style, and the peace of mind of a manufacturer with more than a century of scale and distribution behind it. The Landmark Impact brings Class 4 protection with outstanding granule adhesion.

Either way, go Class 4 for Oklahoma. A standard architectural shingle will survive most storms; a Class 4 shingle is built for the storms Oklahoma actually sends. And remember: the brand on the bundle matters far less than the crew nailing it. Proof Construction is a manufacturer-certified installer for premium lines, and we'll help you pick the right product for your roof, your budget, and your neighborhood — then install it to the letter of the manufacturer's spec.
