The answer to 'difference between architectural shingles and 3-tab shingles' is that architectural shingles, also known as dimensional or laminate shingles, are a more premium roofing option compared to 3-tab shingles. Architectural shingles have a thicker, multi-layered design that creates a more dimensional, textured appearance on the roof. They also tend to be more durable and longer-lasting than 3-tab shingles.
In contrast, 3-tab shingles are a more basic, flat shingle design. They are typically less expensive upfront but may not last as long as architectural shingles. 3-tab shingles are a popular choice for homeowners on a tighter budget, while architectural shingles are often preferred for their enhanced aesthetic appeal and performance.
