What is the main purpose of installing eave closures in a tile roofing system?

The primary purpose of installing eave closures in a tile roofing system is to prevent birds, insects, and small animals from nesting in the ends of the first tile course. This is crucial because open ends of the tiles can create entry points for these creatures, which can lead to infestations and potentially damage the roofing system over time. By effectively sealing these openings, eave closures help maintain the integrity of the roof and protect the structure from unwanted pests that might compromise the roof's lifespan.

In addition to pest prevention, eave closures can contribute to the overall performance of the roofing system by ensuring that tiles remain securely in place and that water drainage is managed appropriately, thus further enhancing the roof's durability. While factors like material cost, water leak prevention, and aesthetic appeal are important in roofing considerations, the direct role of eave closures primarily focuses on pest prevention.
