Mapping each roof plane first helps connect interior symptoms to tile, flat, wall, drainage, and transition details without jumping to a scope.
Draw a simple roof-plane map
Begin by naming each distinct area: front tile plane, rear tile plane, low-slope patio, foam section, metal canopy, parapet, wall connection, or equipment curb. A sketch does not need architectural precision. Its purpose is to give photographs, leak notes, and proposal items a shared location instead of relying on phrases such as “the back part.”
Mark interior symptoms on the same map. A stain may sit below one plane while the entry point begins at a wall or transition farther upslope. Note prior repairs, equipment work, solar or mechanical access, and where drainage leaves the flat areas. This context helps the inspector test a water route rather than stopping at the nearest visible defect.
- Roof material and slope for each plane
- Walls, valleys, penetrations, curbs, drains, and scuppers
- Interior stain or leak location
- Previous repairs and rooftop access history
Inspect the tile field and layers below it
Tile photographs should show the full plane before focusing on broken pieces, shifted rows, valleys, penetrations, walls, or edges. Surface tile is only part of the water-control assembly. Underlayment, battens, flashing, fasteners, and deck details affect whether a limited repair can be tied into sound surrounding work.
Ask which conditions were visible without disturbing the system and which would require lifting tile or opening an area. If the proposal includes removal, it should explain the expected boundary, reusable material, replacement tile, underlayment or flashing work, deck allowances, and how an unexpected condition will be photographed and approved.
Inspect flat and foam sections differently
A low-slope plane adds coating continuity, exposed foam, cracks, punctures, blisters, adhesion clues, previous patches, traffic, drainage, ponding clues, parapets, curbs, and scuppers. Wide photographs should identify the water route. Close views should show the surface condition without losing the relationship to drains and transitions.
A worn-looking surface does not automatically require replacement. Maintenance, localized repair, or recoat may be considered when the underlying system can support it. The recommendation should address preparation, moisture, drainage, compatibility, and a durable stopping point rather than relying on a fixed age or generic recoat schedule.
Give transitions their own inspection record
Where tile meets a flat section, the change in slope and material changes how water moves. Photograph the overlap, flashing, underlayment termination, coating or membrane edge, wall connection, and adjacent condition. Similar attention belongs at skylights, pipes, parapets, equipment curbs, valleys, and headwalls.
A transition is also a scope dependency. One area may need to be opened before the neighboring system can be finished. The proposal should identify responsibility for removal, preparation, flashing, tie-in, temporary weather control, and final review so one completed plane does not interrupt another.
Compare finish protection and written boundaries
Roof work can affect access routes, removed tile, staged materials, landscaping, exterior finishes, debris control, and occupied spaces. Relevant protection and cleanup expectations belong in the written scope. Finished appearance, reusable tile, visible flashing, coating limits, and closeout photographs should be discussed when they affect the homeowner’s decision.
Compare repair and replacement options by roof plane. Ask what each option addresses, where it stops, how the transition is restored, and what remains outside the work.

Do not climb onto a wet, hot, or damaged roof. Record what you can see safely from the ground or inside and leave roof access to trained professionals.
