Start with the location, because it shapes what a technician looks at first. The centre of Al Slymanya sits at 24.7088, 46.6945, about 2 km from the centre of Riyadh, with an approximate radius of 3.3 km, and it sits about 612 m above sea level. For a restaurant roof, that means the district is inland and fairly elevated, so the first things checked are the condition of the roof surface, the drainage outlets, and any ponding after rain, since water that stands on a flat roof is the usual route into the kitchen ceiling below.
What is left to the site visit is the detail that no general description can settle. The technician needs to see the actual roof: whether the existing layer is liquid-applied, bitumen membrane or spray foam, whether there are cracks or blisters, how the upstands and parapets are finished, and where the roof penetrations for extract fans, grease ducts and air-conditioning units are placed. Restaurant roofs also carry heavy equipment and frequent foot traffic from staff and maintenance, so the visit should note any worn areas and any places where the membrane has been damaged by equipment being moved. The choice between a liquid roof system, a bitumen membrane, or an insulation layer using XPS boards is made on site, once the existing condition and the roof's use are known.
To help the technician, the customer should prepare a short set of information before the visit. Note when leaks were last seen and in which part of the kitchen or dining room, and whether the leaks follow heavy rain or happen during normal use. Share any previous roof works, the age of the building if known, and the positions of tanks or plant on the roof. Clear access to the roof and to the ceiling below is useful, so the team can trace water paths. Finally, mention any planned changes to kitchen equipment, since new extract systems affect where the roof must be sealed.
For restaurants, visits are planned outside service hours and recorded for the premises file.
