Picture a restaurant owner in Al Yrmwk whose kitchen extraction and rooftop seating sit directly under a flat roof that takes the full force of the afternoon sun. Over a few seasons, a small leak above the dry store turns into staining on the ceiling, a sour smell near the walk-in cold room, and a growing worry that health inspectors or guests will notice before the owner does. The roof is rarely the first thing a restaurant owner thinks about, but for a business that depends on uninterrupted service, it is one of the most important.
Al Yrmwk sits about 15.2 km from the centre of Riyadh, within an area of roughly 3.2 km radius, and its centre stands about 598 m above sea level. For a restaurant roof, this means the site is inland and relatively elevated, so heat gain and daily temperature swings are real factors for roof membranes, while the distance from the city centre makes a quick repair visit less convenient than in a central district. Planning ahead, rather than reacting to a leak during dinner service, is the sensible approach here.
A practical sequence starts with a site inspection of the roof surface, drains, parapets and any penetrations for kitchen vents and air-conditioning units. Next, decide the system: liquid roof waterproofing is priced at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 15–30 per m² for insulated roofs. Where cracks are visible, crack injection at SAR 40–125 per metre should be scheduled before the main coating goes on. Get written quotes that state the area in square metres, then book work for a cooler, dry period and keep kitchen traffic off the fresh surface until it has cured.
For restaurants, visits are planned outside service hours and recorded for the premises file.
