Landmark Life Birchwood shingles deliver architectural roofing performance at approximately 80 pounds per bundle, featuring 13 1/4” x 38 3/4” dimensions with a 5 5/8” exposure. These dual-layer construction shingles combine cedar shake aesthetics with measurable 110 mph standard wind resistance, upgradeable to 130 mph or 160 mph. For Montana contractors dealing with chinook winds and heavy snow loads, the combination of UL 2218 Class 3 impact resistance and UL Class A fire rating addresses real jobsite concerns.
Wind and Impact Performance That Matters
Standard 110 mph wind resistance covers most Montana installations, but the upgrade path to 130 mph or 160 mph gives contractors flexibility for exposed ridgelines and wind corridors. The 15-Year 110 mph wind-resistance warranty backs up the performance claims with actual coverage.
UL 2218 Class 3 impact resistance handles Montana’s summer hailstorms. This rating means the shingles survived multiple strikes from 1.75-inch steel balls without cracking — real-world protection that translates to fewer callbacks after storms. Combined with UL Class A fire resistance (UL 790, ASTM E108), these shingles meet wildfire zone requirements across Montana’s expanding WUI areas.
The certification list runs deep: ASTM D3462, ASTM D3018 Type I, ASTM D3161 Class F, ASTM D7158 Class H, ICC-ES ESR-1389 & ESR-3537, Miami-Dade County Approved, Florida Product Approval FL5444. While Miami-Dade approval seems irrelevant in Montana, it demonstrates the shingles handle extreme weather testing that many competitors skip.
Installation Specifications and Weight Considerations
| Specification | Value |
|---|---|
| Dimensions | 13 1/4” x 38 3/4” |
| Exposure | 5 5/8” |
| Weight per square | 219-238 lbs |
| Weight per bundle | Approx. 80 lbs |
| Shingles per square | 66 |
| Bundles per square | 3 |
At 80 pounds per bundle, crews working at elevation feel the difference. That’s heavier than standard 3-tab but manageable for the durability gain. The NailTrak extra-wide nailing zone speeds installation — critical when you’re racing October weather. Installation follows standard 4-nail or high-wind 6-nail patterns with corrosion-resistant roofing nails.
CertaSeal adhesive and QuadraBond layer bonding create the wind uplift resistance. These aren’t marketing terms — they’re the physical mechanisms that keep shingles attached during chinook events. Shadow Ridge or Mountain Ridge hip & ridge shingles complete the system.
Warranty Coverage and Long-Term Protection
The Lifetime Limited Transferable Warranty includes 10-Year SureStart Protection — full replacement coverage during the period when manufacturing defects typically surface. StreakFighter technology backs a 10 to 25-Year Algae-Resistance Warranty, though Montana’s dry climate makes algae less critical than in humid regions.
22 shingles per bundle means predictable material calculations. Required accessories include starter shingles, underlayment, and hip & ridge caps — standard for any quality installation but worth noting for complete job pricing.
FAQ
How does 110 mph wind resistance compare to other architectural shingles? Standard 110 mph resistance matches most quality architectural shingles, but the upgrade path to 130 mph or 160 mph sets Landmark apart. Most competitors max out at standard ratings without upgrade options.
What makes Class 3 impact resistance worth the premium? UL 2218 Class 3 rating means surviving 1.75-inch hail impacts. In Montana’s hail-prone areas, this translates to fewer insurance claims and longer roof life. Some regions offer insurance discounts for Class 3 or higher ratings.
Do the extra features justify the weight penalty? At 80 pounds per bundle, these weigh more than budget options. The dual-layer construction that creates the weight also delivers the impact resistance and wind performance. For permanent roofing, the trade-off makes sense.
How critical is the algae resistance warranty in Montana? The 10 to 25-Year StreakFighter Algae-Resistance Warranty matters less in Montana’s dry climate than in humid regions. Consider it bonus protection rather than a primary selling point for local installations.
