What causes terrace leaks in Guwahati?

Monsoon, flat roofs, and failed membranes — why terrace leaks are so common in Northeast India.

Guwahati receives over 1,600mm rainfall annually, mostly concentrated in monsoon months. Flat terrace design — standard in apartment construction — allows water to pond if slope is inadequate. Over time, UV and heat cycling degrade waterproofing membranes. Penetrations around pipes and parapet upturns fail first. The fix starts with diagnosis: flood test and tracing water path before any new coating.
