What do different manufacturers of asphalt shingles have that can vary?

Different manufacturers of asphalt shingles often have variation in installation requirements due to differences in their specific products’ designs and recommendations for best practices. Each manufacturer might have proprietary installation guidelines to ensure that their shingles perform as expected in accordance with their warranty agreements. These installation instructions can include specific nailing techniques, ventilation requirements, or underlayment specifications, which can affect the overall performance and durability of the roofing system.

While color options, warranty terms, and material composition do also vary among manufacturers, installation requirements are particularly crucial because improper installation can lead to issues such as leaks or underperformance of the shingles, regardless of their quality or design features. Thus, understanding these variations is essential for both proper application and maximizing the lifespan of the shingles.
