Team note on Dhahran: 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..

Before any quote is given for a bitumen membrane on a clinic roof in Dhahran, the first thing checked is the site's position relative to the coast and to ground level. The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data), and the city is about 5.9 km from the sea coast (OpenStreetMap). Both facts matter because they shape how water drains off a flat clinic roof and how much exposure the membrane faces, so the technician notes the roof's fall, its drainage outlets and its distance from the parapet before measuring the area. Bitumen membrane is priced at SAR 15–35 per m², and that range only means something once the roof's true area and condition are known.

What is left to the site visit is the detail that no map can show. The technician walks the roof to find blistering, lifted laps, ponding areas and old patches, and checks whether the existing layer can be overlaid or must be stripped back to the deck. Upstands at plant units, ventilation ducts and the edges around rooftop equipment are inspected by hand, because a clinic roof often carries more penetrations than a plain residential roof. Any crack or joint that needs injection is recorded separately, since crack injection is priced per metre at SAR 40–120 per m and is not part of the membrane figure. The site visit also confirms access for materials, safe working routes for staff and patients, and any restrictions on working hours around the clinic's operations.

Information that helps the technician arrive prepared includes a roof plan with dimensions, the age of the existing covering, any previous leak reports, and a list of rooftop fixtures and their locations. It also helps to tell the technician whether the roof is used for anything beyond maintenance, such as a helipad area, a generator platform or a cooling unit bay, because each changes the traffic and the load the membrane must carry. Where insulation sits beneath the membrane, the presence of XPS boards at SAR 12–30 per m² should be noted early, so the scope reflects the full build-up rather than the surface alone. Clear answers to these points let the technician price the work accurately and schedule the job with minimal disruption to the clinic.

For clinics, work is scheduled around patient hours and kept to the areas that need it.
