What term describes shingles that contain factory-applied strips or spots of adhesive for self-sealing?

The term that refers to shingles with factory-applied strips or spots of adhesive for self-sealing is identified as self-sealing shingles. This specific design feature allows the shingles to adhere to one another once they are installed and heated by the sun, which helps to prevent wind uplift and provides additional water resistance.

Self-sealing shingles are commonly used in residential roofing because they enhance durability and overall roof performance. The adhesive areas are strategically placed to ensure that the shingles bond securely, contributing to the roof's longevity and resilience against harsh weather conditions.

In contrast, architectural shingles, which are often thicker and offer a more dimensional appearance, do not necessarily include self-sealing elements. Three-tab shingles are a traditional style characterized by their flat appearance and three tabs, but they may not inherently have self-sealing capabilities. Laminated shingles refer to shingles that have multiple layers for added strength and a more textured look, which also do not specifically indicate the self-sealing function. Thus, the clear and defining feature of self-sealing shingles is the inclusion of factory-applied adhesive for enhanced performance.
