According to numerous manufacturers and roofing experts, high-quality Class 4 shingles often come with warranties for up to 50 years, and their real-world life expectancy can range from 30 to 50 years, significantly longer than standard shingles. It is important to clarify that **Class 4 shingles** refer to a type of roofing material, not a medical condition like the 'shingles' virus, which falls under the topic of general health. This article explores what Class 4 shingles are and the factors influencing their longevity.

Many people mistakenly apply roofing classifications to the medical condition. The terms 'Class 3 or 4' refer exclusively to the impact resistance of asphalt roofing shingles and have no relevance to the diagnosis or severity of the viral infection, herpes zoster, more commonly known as shingles.
