How much does it cost to repair a leaking roof in Dubai?

Flat roof leak repair in Dubai typically costs AED 1,500–AED 8,000 depending on the size of the affected area and the repair method required. For a small localised crack or failed sealant joint, a patch repair sits at AED 1,500–AED 3,000. For a larger area requiring full waterproofing membrane replacement, expect AED 4,000–AED 8,000+. The most common causes of flat roof leaks in Dubai villas are: cracking or shrinkage of the existing waterproofing membrane due to extreme UV and heat exposure (membranes typically last 8–12 years here, less if low-quality); failed sealant around roof penetrations such as AC units, drainage outlets, and parapet walls; and poor original installation where water pools rather than draining. After rain — even heavy dew — is actually one of the most common times leaks reveal themselves, because Dubai's long dry spells allow small cracks to seal with dust, which then flush out under water. Before agreeing to any repair, ask the contractor to identify exactly where the water is entering — this is not always directly above where it appears inside. A water test (flooding a section of the roof) can help locate the source. Avoid contractors who offer to patch without diagnosing the root cause, as surface patches on a failing membrane rarely last more than a season. A full torch-on bitumen membrane or liquid-applied waterproofing system is a more durable long-term solution.
