Before we start: what we know about Alhait
The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).
An owner of a small restaurant in Alhait often finds the roof is the least visible part of the building until something goes wrong. Kitchen extract work, rooftop seating, and stored equipment all add weight and foot traffic up there, and a leak can reach the dining room or the kitchen ceiling before anyone notices. Many owners only think about the roof when staining appears, by which point repairs are more disruptive and more costly.
The local setting matters here. The centre of Alhait sits about 980 m above sea level (SRTM open elevation data), so the area experiences a climate and terrain that differ from low-lying coastal cities. For a restaurant owner, this means planning roof protection as part of regular property care rather than a one-off job. Liquid roof waterproofing is typically priced at SAR 8–25 per m², while a bitumen membrane runs SAR 15–35 per m² and XPS boards SAR 12–30 per m². Comparing these options against the roof area and how heavily the space is used helps set a realistic budget before any work is booked.
Practical steps help keep the process orderly. Begin by walking the roof after rain and noting ponding areas, cracks, and any staining on the ceiling below. Next, measure the roof area in square metres so you can estimate costs using the rates above. Then ask for a written scope that names the system proposed, the surface preparation included, and the cost per m², and check whether crack injection, quoted at SAR 40–120 per metre, is needed for any hairline splits. Finally, schedule the work outside peak service hours and plan a short inspection after the first heavy rain to confirm the roof is performing as expected.
For restaurants, visits are planned outside service hours and recorded for the premises file.
