Inspecting beneath the gravel protection

Gravel protects the covering but can also conceal defects. Bare areas, debris near drains and repeated repairs warrant an assessment. A photograph alone cannot establish the condition of concealed layers.

Repair or a different system?

The choice depends on the extent of damage, moisture within the assembly and connection details. Age is a clue, not a diagnosis. A localized repair can be discussed when the rest of the roof is sound.

Planning a TPO or modified-bitumen replacement

A conversion requires a defined removal scope, debris management and substrate preparation. Slopes, drains and flashing heights also need review. Simply covering a wet roof does not address the underlying cause.
