Product Research
Malarkey manufactures roofing products specifically engineered for high-moisture, high-moss-pressure climates. This guide covers what distinguishes Malarkey shingles from standard architectural products and helps you understand which product line fits your home's exposure, budget, and goals.
Standard architectural shingles are formulated for the statistical average of North American climates. Clark County and the Portland Metro are not average. The combination of 40+ inches of annual rainfall concentrated in sustained winter events, biological pressure from moss and algae in shaded and tree-canopied yards, freeze-thaw cycling along the Gorge corridor, and periodic high-wind events creates a roofing environment that tests material properties in specific ways.
Malarkey's response to this is Rubberized Asphalt — SBS (styrene-butadiene-styrene) polymer-modified asphalt used in their mid-to-premium lines. SBS modification keeps the asphalt matrix flexible at lower temperatures, reducing the cracking and seam-failure that standard asphalt experiences during freeze-thaw stress. The AR (algae-resistant) designation across their product lineup means built-in granule-based inhibitors, not a surface coating that wears off in the first few Northwest rainy seasons.
As a Malarkey Emerald Premium Contractor, Left Coast Exteriors is trained and certified to install these products correctly — including proper underlayment selection, ventilation assessment, and flashing integration that determines whether a shingle performs to its rated life or falls short of it.
Emerald Premium Status
Emerald Premium is Malarkey's highest installer certification. It requires verified training, background-checked crews, and demonstrated customer satisfaction performance — and it's the credential that unlocks the workmanship warranty component of a full-system warranty. When Left Coast installs a Malarkey roof, the homeowner gets both the product warranty and the workmanship coverage that most contractors cannot offer.
Every shingle we install is a Malarkey product. Here's how the lines differ and which situations each one fits best.
The Highlander is Malarkey's reliable entry-level architectural shingle, designed for standard residential applications across the Pacific Northwest. It includes Scotchgard Protector technology for algae resistance and delivers consistent performance for homes in moderate-exposure locations. The right choice when budget is the primary constraint and the property doesn't face elevated wind or impact risk. Not a Rubberized Asphalt product — standard asphalt construction.
The Vista AR steps up from entry-level with improved granule adhesion, enhanced algae resistance, and better weather performance — without crossing into full impact-resistant territory. A practical choice for homeowners who want a genuine upgrade in material quality without stepping into the Class 4 tier. It bridges the performance gap cleanly for budget-conscious buyers in moderate-exposure locations.
The Legacy AR is our most common recommendation for Clark County homes. Malarkey's Rubberized Asphalt technology gives it flexibility that standard architectural shingles can't match — a meaningful advantage for homes along the Gorge corridor where freeze-thaw cycles and temperature swings stress shingle integrity. Class 4 impact rated, algae-resistant, 30-year limited warranty. For homeowners planning to stay long-term who want the best performance-per-dollar available in a Malarkey shingle, the Legacy AR is the clear recommendation.
The Windsor AR is Malarkey's premium designer laminate — a Class 4 impact shingle with a heavier, multi-layered profile that creates a more dimensional, architectural appearance. Enhanced shadow lines and premium granule blends give Windsor roofs a visual weight that reads from the street. Carries a 50-year limited warranty and transfers with the home sale. The right choice for homeowners who want the highest-performing, best-looking Malarkey roof available and want that as a selling point at resale.
What distinguishes Malarkey's mid-to-premium lines from standard architectural shingles in this specific climate.
Rubberized Asphalt stays flexible at low temperatures, reducing the cracking and adhesion failures that standard asphalt experiences during freeze-thaw cycling. A direct response to the Pacific Northwest's specific shingle failure modes — not a feature relevant to warmer, drier climates.
AR granule technology is integral to the asphalt matrix — not a surface coating that wears off in the first few wet seasons. In Pacific Northwest yards with tree canopy and sustained shade, the difference between a coating and an integral treatment shows up over 10–15 years.
Emerald Premium is the certification tier that enables access to the workmanship warranty component alongside the standard product warranty. Most contractors can only offer product coverage — workmanship warranty eligibility through Emerald Premium certified contractors like Left Coast Exteriors is subject to applicable Malarkey warranty requirements and system specifications.
The right product depends on your home's location, exposure, and goals. Here's how we think about it.
Highlander or Vista AR. Interior Vancouver neighborhoods, single-story homes with moderate tree coverage and no Gorge exposure. If you're on a tight budget and the home isn't in an elevated-risk zone, these deliver reliable performance without overspending.
Legacy AR. Homes with freeze-thaw exposure along the Gorge corridor, elevated east-side Vancouver neighborhoods, rural Clark County, and homes with significant tree canopy. Rubberized Asphalt + Class 4 impact rating covers the structural failure modes this climate produces — freeze-thaw stress, impact, and wind load. Algae staining is addressed by the AR granule technology; moss management is a separate maintenance consideration.
Windsor AR. Camas, Washougal, Gorge-corridor homes, waterfront properties, or any homeowner who wants maximum performance and the visual upgrade that comes with a designer-grade shingle profile. The 50-year transferable warranty is also a real differentiator at resale.
We make a specific product recommendation at every estimate based on the actual home — exposure direction, shading, pitch, current failure mode, and homeowner goals. We don't give one-size-fits-all answers.
Emerald Premium status enables us to offer the complete warranty package: product + workmanship. Most contractors can only offer the product warranty because they haven't earned the certification tier. When we install a Malarkey roof, you get both components of coverage.
We match the product to the home's actual exposure and the homeowner's goals. If the Highlander is the right answer for your budget and location, that's what we'll recommend. If your Gorge-corridor home needs Legacy AR, we'll explain why. We don't upsell for commission.
A Malarkey shingle installed incorrectly — wrong underlayment, missed flashing details, improper ventilation — fails before its rated life and may void the warranty. Emerald Premium training covers the installation details that determine whether the warranty is real or theoretical.
Our roof replacement service covers Southwest Washington and the Portland Metro. Product recommendations are tailored to each city's specific exposure conditions.
Malarkey's mid-to-premium lines use Rubberized Asphalt — SBS polymer-modified asphalt that stays flexible across a wider temperature range than standard asphalt. In Pacific Northwest climates, freeze-thaw cycling and temperature swings stress standard asphalt adhesion and cause brittleness. SBS modification directly addresses these failure modes. The AR designation indicates built-in algae-resistant granule technology, not a surface coating that wears off.
Emerald Premium is Malarkey's highest contractor certification tier. It requires verified installation training, background-checked crews, and sustained customer satisfaction performance. Emerald Premium status enables contractors to offer the enhanced workmanship warranty alongside the product warranty — giving homeowners full-system coverage rather than just the material component. Left Coast Exteriors carries Emerald Premium status.
For most Clark County homes, the Legacy AR. Class 4 impact rating, Rubberized Asphalt technology, 30-year limited warranty — it directly addresses the freeze-thaw and wind stress conditions that define this climate. The AR granule technology addresses algae-related staining separately; moss management is its own maintenance consideration. For premium homes, Gorge-corridor properties, or homeowners positioning for resale, the Windsor AR's 50-year warranty and designer profile make it worth the step up. We make a specific recommendation at every estimate.
Malarkey product warranties are generally transferable to subsequent homeowners. The transferability details, including any fees or registration requirements, are governed by the specific product warranty document. When we complete an installation, we register the project with Malarkey and provide the homeowner with documentation that supports a future transfer. The 50-year Windsor AR warranty is a meaningful selling point for this reason.
No — algae and moss are different organisms that require different responses. Algae (primarily Gloeocapsa magma) causes the dark streaking common on Pacific Northwest roofs in shaded, humid conditions. Malarkey's AR granules contain copper and zinc compounds that inhibit algae growth at the granule level — integral to the asphalt matrix, not a surface coating that wears off in the first few wet seasons. Moss is a different organism. It establishes root-like structures (rhizoids) that can physically lift shingle granules and hold sustained moisture against the roof surface. AR granule technology does not prevent moss establishment. If your property has significant shade and tree canopy — common throughout Clark County and the Portland Metro — moss management (including periodic roof cleaning and, in some cases, zinc strip installation) is a separate maintenance consideration regardless of which shingle product is installed. We assess moss risk during every roofing estimate and can advise on what's realistic for your specific property.
