Roof waterproofing for restaurants in Al Nkhyl, Riyadh starts with the roof itself, not the price list. The centre of Al Nkhyl sits at 24.7422, 46.6375, about 5 km from the centre of Riyadh, and the area covers an approximate radius of 3.9 km. It also sits about 622 m above sea level, according to SRTM open elevation data. The nearest wadi channel is about 1.4 km from the centre of Al Nkhyl, so the technician first checks how water would move off the roof and where it would drain during heavy rain. Restaurant roofs often carry kitchen extraction units, ducting and plant fixed on upstands, so the first checks cover drainage outlets, the state of the upstands and any ponding left after a storm.
Some points can only be settled at the site visit. The technician looks at the existing surface and decides whether a liquid roof waterproofing system, a bitumen membrane or an insulation layer such as XPS boards suits the slope and load. The quantity of crack injection, if cracks are found, depends on their length in metres, and the area to be coated depends on measurements taken on the roof. Because Al Nkhyl has both villas and apartment buildings, the restaurant may share a roof line or parapet with neighbouring properties, so access and any shared drainage are confirmed on the day. Rates for liquid roof waterproofing run from SAR 10–25 per m², bitumen membrane from SAR 15–35 per m², and XPS boards from SAR 15–30 per m², but the final figure is set only after the roof has been measured and inspected.
To help the technician arrive prepared, the restaurant should share the roof plan or a rough sketch, the number of drainage outlets, any kitchen extraction or plant on the roof, and the times when the kitchen is quiet so work does not disturb service. Please also note any past leaks, ceiling stains or areas that stay wet after rain, as these guide the choice of method. Keep access to the roof clear, and let the team know if the building has water tanks on the roof, since tank internal coating is priced separately at SAR 25–65 per m². A clear description of the problem areas lets the visit focus on the right parts of the roof from the start.
For restaurants, visits are planned outside service hours and recorded for the premises file.
