Mortar-set clay tile maintenance

Restore critical mortar details on a fully mortar-set clay tile roof.

Zenith evaluates and restores deteriorated mortar at clay tile hips, ridges, rakes and transitions when the roof’s condition supports focused mortar-booster work.

A complete roofing decision

Start with the actual roof assembly, not just the visible tile.

Inspect the mortar-set details, remove loose or failed material where included, prepare the area, install compatible new mortar and complete the affected clay-tile transitions. The final scope follows the roof condition, complete drainage paths and the selected material system.

Deck and dry-in

Once the roof is opened, Zenith can identify exposed deck and wood conditions before new waterproofing covers them.

Flashing and drainage

Valleys, walls, chimneys, skylights, penetrations and edges are planned to shed water in the correct order.

Tile layout and finish

Tile profile, accessory pieces, ridges, hips, rakes and transitions are part of the completed roof system.

Clay and concrete are not interchangeable

Clay Tile Mortar Booster for the roof you actually have.

This service addresses two-piece clay, S-tile and Spanish tile profiles. Zenith confirms the installed profile, available compatible materials, roof geometry and the practical scope before work is scheduled.

Existing tile may be reusable in some lift-and-lay scopes; exact profile and color matching cannot always be guaranteed when older tile is discontinued.

Choose the responsible scope

Repair, lift and lay, or replacement depends on what is still serviceable.

A mortar booster is a focused maintenance or repair path. It does not replace a needed lift and lay or roof replacement when the waterproofing below the tile has broadly failed.

Focused repair

Appropriate for a clear, isolated defect with a reliable tie-in to the surrounding roof.

Lift & lay

Useful when serviceable tile can remain while the aged waterproofing system beneath it is renewed.

Full replacement

Considered when the existing tile, roof system or design goal no longer supports a durable reuse path.
