Commercial Roofing Systems We Install

Every property has different performance and aesthetic goals. Landmark Roofing & Siding installs top-rated commercial roofing systems from manufacturers we trust—each selected for its proven track record in the Pacific Northwest.

Duro-Last Single Ply Commercial Roofing

Known as the “World’s Best Roof®,” Duro-Last is a custom-fabricated PVC membrane ideal for flat or low-slope buildings such as apartment complexes, retail plazas, and light-commercial facilities. Its welded seams create a watertight system that resists ponding, chemicals, and UV damage.
Best for: property owners seeking a long-term, low-maintenance solution with a 15–30 year manufacturer warranty.

Composition Roofing Systems (Malarkey & CertainTeed)

For steep-slope commercial and multi-family properties, we install architectural and designer shingles from Malarkey Roofing Products and CertainTeed Roofing Systems—two of the most trusted names in asphalt composition roofing.

Malarkey Architectural Shingles

Built with NEX® Polymer Modified Asphalt, Malarkey shingles upcycle rubber and plastics for superior flexibility, impact resistance, and granule adhesion. They feature 3M™ Smog-Reducing Granules and Class 3–4 impact ratings—making them durable, sustainable, and perfect for Pacific Northwest weather.
Best for: Property owners seeking a cost-effective, eco-friendly, and long-lasting asphalt roofing solution.

CertainTeed Luxury Shingles

CertainTeed’s architectural lines, such as the Presidential Shake TL, offer heavyweight durability and timeless beauty. These shingles are thicker and more dimensional than standard composition roofing, delivering exceptional wind and weather protection with a refined appearance.
Best for: HOAs, condos, and luxury properties that want the look of cedar or slate with the strength and low maintenance of asphalt.

Nu-Ray Metals Standing Seam Roofing

Locally manufactured in Washington, Nu-Ray Metals produces high-performance metal roofing systems made from aluminum and steel, with optional copper and stainless steel profiles. Their standing seam panels are engineered for strength, longevity, and curb appeal—built to handle the Pacific Northwest’s heavy rain, wind, and temperature swings.

One of the most significant benefits of metal roofing is its longevity. Metal roofing can last 40-70 years or more with proper maintenance, making it a cost-effective choice in the long term. Metal roofing is also highly durable and resistant to extreme weather conditions, such as hail, high winds, and fire.

Best for: commercial buildings, mixed-use developments, and HOA communities seeking a modern, energy-efficient roof with minimal maintenance.

Why We Recommend These Systems

Each of our roofing systems is selected for its proven success in the Pacific Northwest’s wet, variable climate. Whether you need the watertight protection of Duro-Last, the longevity of Nu-Ray Metals, or the aesthetic and performance balance of composition roofing, Landmark Roofing & Siding installs every system to manufacturer specifications to ensure long-term performance and full warranty eligibility.
