Why An Nahdah homes need roof insulation
Villas and apartment buildings define An Nahdah in east Riyadh, beside Khurais Road. Villa roofs are wide, multi-level and crowded with AC bases and annexes, and every joint or opening is a weak point for rain or AC condensate. 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.
