Qatif sits close to the coast, with its centre about 5 m above sea level and roughly 2.5 km from the sea. Those two facts shape what a technician looks at first on a bitumen membrane job. Low ground and nearby sea air mean that moisture and salt can sit against a roof or basement wall for longer, so the first checks focus on signs of water already getting through: staining on ceilings, bubbling or lifted edges on the existing surface, and any dark patches that suggest moisture is trapped beneath. The technician will also look at where water drains from the roof and whether ponding has broken down the surface.
Some points can only be judged on the day. The condition of the existing substrate, whether it is level, dry, and free of loose material, is best assessed on site, as is the exact length of any upstands, drain outlets and joints that need detailing. The access route, the height of the roof, and how the membrane will be lapped around fixtures are also left to the visit. Where a bitumen membrane sits alongside other work, such as crack repair or a separate coating on a tank or basement, the technician will confirm which area needs which system before any price is discussed.
For the technician's planning, the published range for bitumen membrane in Qatif is SAR 15–35 per m². The same range is listed for other systems so you can compare: liquid roof waterproofing at SAR 8–25 per m², XPS boards at SAR 12–30 per m², and spray foam at SAR 20–45 per m². Crack injection is quoted separately at SAR 40–120 per metre. Please note that these figures are published offers, and the final cost depends on the measured area and what the site visit reveals. Share the roof dimensions, the number of drains and any visible leak locations when you book, so the technician arrives ready to assess the job properly.
Prices shown on this page come from our own published price list for the city; the final price is set after inspection.
