Fiberglass shingles typically take about 20 to 30 years to decompose in landfills. However, the exact time can vary based on environmental conditions and the specific materials used in the shingles. While fiberglass itself is more durable than organic materials, the asphalt coating can also affect the degradation process. Proper recycling and disposal methods can help mitigate their environmental impact.
