- Loose or cracked roofing sheets or tiles at laps
- Aged membrane on a flat RCC roof
- Blocked valley or gutter dumping water against a wall
How Gracia diagnoses
Evidence before treatment
Roof-type first: RCC, tile or sheet. Then penetrations, laps and the ceiling below. Thermal when the stain is offset. Sheet-roof work is not a PU terrace spec copied across.
Kukatpally heat coats, Kompally walkable terraces and older independent-house sheet roofs in Quthbullapur are different jobs. We quote the roof you have.
Probable
Evidence indicates the cause; further verification may still be required.
Possible
One or more clues exist, but the evidence is not enough for a firm conclusion.
Excluded
Inspected, and no supporting evidence found in the inspected area.

About this problem
Terrace usually means a walkable flat RCC roof. Sloped tile and metal sheet roofs fail at laps and flashings. We inspect the roof type first so the treatment matches.
