About Az Zahra
Az Zahra is a district in Al Malaz municipality between Makkah Road to the north and Al Malaz to the south, next to Ad Dhubbat and Ar Rabwah, mixing villas, apartments and shops. The range of building ages means some need first-time roof and wall insulation while others need damaged layers removed and new heat- and leak-resistant systems fitted. District guide
Why Az Zahra homes need roof insulation
Villas, apartment buildings and shops and commercial buildings define Az Zahra in central Riyadh, beside Makkah 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.
