StormMaster® LM Architectural Shingles
When the weather is at its roughest,
StormMaster® is at its toughest.
StormMaster® high wind and impact resistant designer shingles excel in protecting your home from the most extreme weather conditions. SBS (styrene butadiene styrene) is blended into our asphalt shingle formula to enhance the flexibility, strength, and durability of StormMaster®, creating a shingle that resists cracking, splitting, warping or shrinking in hot or cold weather. When correctly installed, StormMaster® shingles are designed to withstand high impact as well as high wind velocities.
StormMaster® is available in two shingle types: Stormmaster® ST, a traditional 3-tab shingle which features a 30 year limited warranty, and StormMaster® LM, a laminated architectural shingle which 
comes with an unprecedented 50 year limited warranty. Choose a StormMaster® roof, and stand up to Mother Nature.
