Problem
Top-floor rooms unlivable in May; hairline terrace cracks after summer.

Top-floor rooms unlivable in May; hairline terrace cracks after summer.
Crack map and slope check. Thermal used to confirm no hidden wet pockets before coating.
Dry hairline cracks, no active wet path on the scan. Ponding at one outlet.
Thermal movement cracks plus poor outlet; not an active pipe leak.
Crack treatment, outlet clear, heat-reflective coat.
Visual after first rain; outlet flow check.
Quoted 5-year roof coat. Garden planters added later would void the coat at those points.
Book an inspection. You get the diagnostic report before any coating is sold.
