Grey tile roof: valley joints and local sealing

The valley and its edges

The coated valley channel runs between weathered tile slopes. Several views show sealant applied along both edges, while others show cracked tile edges and rust-coloured debris where tiles meet the channel. The channel and the adjoining tiles need to be assessed together because the water path crosses both.

Sealant and foil tape in view

Fresh sealant is visible along the valley edges and across several cracks, and a roll of foil tape rests on the tiles in one view. These materials cover local openings; how they hold over time depends on preparation and the movement of the adjoining tiles, so a repair scope should say which areas are temporary covers and which are lasting work.

Cracked caps and broken corners

On the hips, one cap is broken away with an open cavity underneath, and sealant appears across other cracked caps and intersections. The condition of each cap and its bedding affects whether sealing, repointing, rebedding or replacement is appropriate.

Planning inspection and repair

When you contact Allen, describe where water appears inside and share photos you have taken safely. The visible sealing does not identify every leak path, so the quotation should separate valley preparation, tile and cap repairs, and cleaning of the heavy lichen before the agreed work begins.
