Landmark 30 Year Weathered Wood Shingles

Landmark 30 Year Weathered Wood shingles deliver proven 110 mph wind resistance and 25-year algae protection with Easy Install sealing strips that cut installation time. At 240 pounds per square and UL Class A fire rated, these architectural shingles handle Montana’s wind events while providing the dual-layered wood-shake appearance contractors’ clients want.

Wind Performance and Installation Speed

The 110 mph wind rating matters when chinook gusts hit 60-80 mph near the Rocky Mountain Front. The shingles carry a 110 mph wind resistance rating and UL Class A fire resistance, specs that translate to fewer callbacks after Montana’s notorious wind events. At approximately 240 lbs per square, these heavy-weight shingles stay put.

The real time-saver shows up during installation. Easy Install sealing strips for simplified roofing work eliminate the guesswork on alignment and speed up the bonding process. When you’re racing to close in a roof before October freeze-up, those sealing strips save hours across a full roof. Standard 3 bundles per square (100 sq ft) with 33.33 sq ft per bundle coverage keeps the math simple for material ordering.

Metric sizing (NW Metric Landmark) implies standard metric layout for architectural shingles, which means consistent nailing patterns and predictable material usage. No surprises when you’re halfway through a roof.

Algae Resistance Technology

StreakFighter® Algae-Resistant technology backed by a 25-year algae resistance warranty addresses the moisture reality in western Montana valleys. Copper-infused granules prevent the black streaking that makes a 10-year-old roof look like it needs replacement.

The technology comparison matters: Standard Landmark offers 25 years of algae resistance, while Landmark PRO offers 30 years. For most Montana applications, the standard 25-year protection handles the job. The copper granules keep working through decades of freeze-thaw cycles and summer humidity.

Retail performance backs up the specs. Lowe’s customers rate them 4.7 out of 5 stars (62 reviews), while SW Collins Co. shows 4.2 stars. Contractors describe them as “good quality at a fair price” and note “ease of use”.

FAQ

How does the 110 mph wind rating compare to Montana’s actual wind conditions?

The 110 mph rating exceeds typical Montana wind events. Chinook gusts near the Rocky Mountain Front hit 60-80 mph, giving you a solid safety margin. The 240-pound weight helps these shingles resist uplift better than lighter alternatives.

What’s the real-world difference between 25-year and 30-year algae protection?

For most Montana applications, 25-year algae protection handles the job fine. The copper-infused granules in standard Landmark shingles prevent black streaking through decades of weather cycles. Landmark PRO’s 30-year protection matters more in consistently humid climates.

Do the Easy Install sealing strips actually save installation time?

The sealing strips eliminate alignment guesswork and speed bonding. On a full roof, that translates to hours saved — critical when you’re racing Montana’s short construction season. Combined with metric sizing for consistent nailing patterns, installation moves faster without sacrificing quality.

How do Landmark shingles handle snow loads?

At 240 pounds per square, these architectural shingles provide solid substrate support for snow accumulation. The dual-layered construction and UL Class A rating mean they’re engineered for severe weather, though specific snow load ratings should reference local building codes and the MSU snow load tool.

Is the Weathered Wood color prone to fading?

The copper-infused granules that provide algae resistance also help maintain color consistency. The gray-brown mix in Weathered Wood masks minor fading better than solid colors. The 25-year algae warranty indicates the manufacturer’s confidence in long-term appearance retention.
