What is typically used as an eave closure in tile roof systems?

In tile roof systems, the use of cement or foam specialty closures is essential as they effectively seal the eaves to prevent moisture intrusion while allowing for proper ventilation. These closures specifically conform to the shape of the tiles and are designed to complement the roofing system's aesthetics and functionality. They help to create a barrier that keeps out wind-driven rain and other debris, contributing to the roof's overall durability and performance.

Using materials like plastic sheeting or asphalt shingles for this purpose would not provide the same effectiveness in sealing the eaves due to their structural characteristics and intended use. Metal flashing could serve a different function in roofing systems and might not form the same fit or seal at the eaves as specialty closures specifically designed for tile roofs. Thus, cement or foam specialty closures are the most suitable choice for maintaining the integrity of tile roofs at the eaves.
