Azl — delivered with a written warranty, to the Saudi Building Code
About Ad Diyafah
Ad Diyafah is an established Najran district regarded as an active property area, crossed by Al Jaish Street and served by Ad Diyafah Health Centre, with apartment buildings offered alongside family homes. Older blocks often need renewed waterproofing layers on roofs and around tanks, and periodic treatment of entrances and service rooms helps limit cockroaches in shared buildings. District guide
Why Ad Diyafah homes need roof insulation
Ad Diyafah in Najran is home to apartment buildings and villas, connected by Al Jaish Street. An apartment building's roof is shared and crowded with AC units and flat tanks, so top-floor residents bear both the heat and the leaks. Intense heat most of the year makes roof thermal insulation a core part of the solution, not an optional extra. The fix: assess the existing system with a moisture survey; restore over it if dry, or strip and rebuild if saturated.
