A tile roof bird stop closes the large profile openings at the eave while preserving the drainage or ventilation paths required by the roof assembly. An open-looking space is therefore not automatically a defect, and filling every opening with foam or mortar can create a different problem. The useful question is whether the installed closure matches the tile profile and the approved eave detail.
Understand which opening you are seeing
Barrel and other shaped tiles leave spaces above the roof edge. Closures may be metal, manufactured pieces or other components specified for that assembly. Some details intentionally provide outlets for water reaching the underlayment. A photograph taken straight up from the ground can make a drainage opening look like a missing closure. Ask the roofer to distinguish the profile opening, the water exit and any intended ventilation path on a labeled photograph.
Plan animal exclusion with the roof detail
Bird nesting, detached closures and debris can occur together. Animal exclusion should not become an improvised roofing repair: adding mesh, screws or expanding foam may obstruct water or damage the weather layers. A useful scope identifies removal of nesting material, assessment of concealed damage and installation of a compatible replacement closure. If wildlife handling is needed, coordinate it separately so the roofer can work on an accessible, cleared edge.
What to request in the repair scope
Ask which closure product fits the tile, how it will be secured and which openings must remain clear. Include any damaged first-course tiles, edge metal or fascia discovered during access. Before-and-after photographs should show more than the finished face; they should establish that the water route has not been blocked. For a replacement project, settle this detail before the eave tiles are installed. There is no single closure choice appropriate to every tile shape and roof configuration.
Can a pest company close the opening?
Coordinate the proposed exclusion work with the roofer before it begins. A pest barrier and a roof drainage detail have different purposes. The written plan should show how the barrier avoids obstructing water outlets or attaching through weather layers without an appropriate repair detail.
