SBS shingles are asphalt shingles modified with a rubber-like polymer that can improve flexibility and impact resistance.
Why It Matters
SBS-modified shingles can be a strong option for homeowners who want a higher-performance asphalt shingle, especially where hail or thermal movement is a concern.
Common Problems
Common confusion includes assuming every premium shingle is SBS, assuming SBS automatically means Class 4, and not checking the specific product rating.
Building Codes & Industry Standards
SBS shingles should be installed according to the manufacturer’s instructions and evaluated by their specific ratings, warranties, and code compliance documentation.
Exterior Echelon Notes
Exterior Echelon explains SBS shingles as a technology category so homeowners can compare real product performance instead of relying on marketing names alone.
