Roof waterproofing in Sharurah: the local context

Team note on Sharurah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data).

Picture the owner of a small restaurant in Sharurah, busy through the evening and proud of a kitchen that runs well. The roof above the dining room has been quietly taking the weather for years. A stain appears on a ceiling corner after a rare shower, then a smell of damp creeps in near the storeroom. The owner wants the problem solved before it reaches the customers, but has no idea which product or method fits a flat commercial roof in this climate.

The local facts matter here. The centre of Sharurah sits about 724 m above sea level, so the town is high ground in the south of the Kingdom, and roofs here face sun, heat and sudden rain in cycles. For a restaurant, a leak is not only a repair bill; it can mean lost covers, damaged equipment and questions from inspectors. Liquid roof waterproofing costs SAR 8–25 per m², making it one of the lighter-touch options, while bitumen membrane runs SAR 15–35 per m² and gives a heavier, longer-lasting layer. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² are worth comparing where insulation is also wanted.

Start with a proper survey. Walk the roof after rain, mark ponding areas, and note every crack or failed seam. Next, decide on the system: liquid coating for light use and simple falls, bitumen membrane where the roof takes foot traffic or heavy equipment, and spray foam or XPS where the kitchen needs cooler ceilings. Price the job by the actual square metres and any crack injection, which is charged at SAR 40–120 per metre. Then book the work for a dry spell, clean the surface, repair cracks first, and apply the chosen layer in the order the supplier specifies. Finish by testing with a hose and a watchful eye on the storeroom ceiling.

For restaurants, visits are planned outside service hours and recorded for the premises file.
