About Dhalalah
Dhalalah is an old residential district in Khamis Mushait near King Fahd Road and Forty Road, close to shopping centres and hospitals, with some properties directly behind Khamis Avenue. Residents say most houses are old or poorly finished and the streets narrow, which makes restoring roof insulation, treating damp walls and sealing gaps against cockroaches and rodents among the most requested jobs. District guide
Why Dhalalah homes need roof insulation
Dhalalah lies in Khamis Mushait along King Khalid Road and King Fahd Road, and is dominated by older traditional houses, apartment buildings and villas. Roofs of older houses often have expired waterproofing, cracked tiles and uneven falls, so water ponds and seeps into the slabs. The altitude brings heavier rain and day–night temperature swings, so flexible materials and careful expansion joints are preferred. The city's cold winters and hot summers cause repeated expansion and contraction, so a flexible system is preferred. The fix: assess the existing system with a moisture survey; restore over it if dry, or strip and rebuild if saturated.
