POOR Shingle and Support
stand behind their product. The "Blistering issue having no effect on
the performance" Defective product and very poor factory support. Look
elsewhere, much better products out on the market.
Malarkey Roofing Products manufactures residential asphalt shingles and commercial roofing products. The Portland-founded business is no longer family-owned or privately held. Holcim acquired Malarkey in 2022, and Malarkey became part of Amrize when Holcim spun off its U.S. business in 2025.
The company traces its roots to Herbert Malarkey’s 1956 business. Malarkey later expanded from Portland to South Gate, California, and Oklahoma City, Oklahoma. The manufacturer credits itself with several early fiberglass- and polymer-modified roofing developments. Because “first” claims are manufacturer claims, they should be read with that attribution. The ownership and milestone timeline is available in Malarkey’s official company history.
Malarkey operates a Certified Contractor program. Eligible contractors can offer specified enhanced or extended warranty options after meeting the current program requirements. Homeowners should verify a contractor’s current Malarkey status and independently confirm licensing, insurance, references, workmanship responsibility, and the written scope of work.
Malarkey’s current residential range includes:
Older lines such as Ecoasis, Alaskan, and Dura-Seal do not appear in the current catalog reviewed for this update. Product availability, impact rating, algae protection, wind provisions, color, and warranty differ by line and region. Check Malarkey’s live shingle overview and the data sheet for the exact product.
Current Malarkey shingles use the company’s NEX polymer-modified asphalt. Malarkey says the formulation incorporates upcycled rubber and plastic. Quantitative claims about tires, bags, or emissions are estimates that depend on the named product and typically assume a 30-square roof. Those assumptions should remain attached to any quoted number.
Impact ratings are also product-specific. Malarkey currently lists Class 4 impact ratings for Windsor, Legacy, and Vista products and Class 3 for Highlander, subject to the applicable product documentation. A laboratory rating does not guarantee that hail will cause no cosmetic or functional damage.
The Asphalt Roofing Manufacturers Association coordinates third-party-verified, industry-average environmental product declarations for asphalt roofing systems. An EPD reports lifecycle impacts under defined product-category rules; it does not by itself establish that one product is environmentally superior. Malarkey should not be described as having invented EPDs with ARMA. See ARMA’s sustainability and EPD information.
Warranty length, non-prorated period, wind and algae coverage, required roof-system components, property type, and Certified Contractor options vary by current shingle. For example, current Windsor literature describes limited lifetime shingle coverage and a 20-year standard non-prorated period, while other lines have different terms.
Older Dura-Seal and universal five-to-15-year summaries should not be used for a current purchase. Read the warranty effective on the installation date and confirm registration, transfer, installation, ventilation, maintenance, exclusions, and whether labor or workmanship is covered. Malarkey publishes its current warranty documents online.
