When it comes to roofing shingles, a 30 year roof is a term used to describe the durability of the material. This type of roofing is designed to last for up to 30 years, and is usually made from materials that are more rugged than other types of shingles. Despite this additional ruggedness, they generally do not require any type of support or additional roof structure. However, this isn't always the best way to judge the quality of roofing shingles today.
Some shingles are longer than others, making the lump weigh more. Other manufacturers use materials that may be heavier or lighter, such as fiberglass which creates a shingle that is lightweight but still very durable. Even with this in mind, most 20-year-old shingles will be more fragile than 30-year-old shingles. Because of their fragility, they will offer less protection against bad weather.
Twenty year old shingles are often referred to as 3-tab shingles and aren't as popular as 30-year-old shingles or architectural shingles. They are also known as dimensional or architectural tiles. Owen's 30-year-old Corning shingles are sold as “Oakridge”.When it comes to choosing a roof for your home, it's important to consider the longevity of the material you choose. A 30 year roof is a great option for those looking for a durable and long lasting roof that won't require any additional support or structure.
It's also important to consider the weight of the material you choose, as this can affect its durability and longevity.
