Why roof & drain maintenance differs in Dhahran

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.. Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

Roof and drain maintenance for schools in Dhahran starts with the site's position, because the terrain shapes how water moves across a flat-roofed building. The centre of Dhahran sits about 16 m above sea level, so rainwater that falls on a school roof has to find its way to outlets and downpipes rather than relying on any natural fall toward the coast. Dhahran is also about 5.9 km from the sea coast, which means the sea breeze carries salt and dust across the roofing layers over time. For these reasons, the first things a technician checks are the outlet openings, the gradient of the drain channels, and any build-up of grit or sand that could block the flow. A school with several wings or flat sections should have each drainage path traced from its highest point to its outlet before anything else is done.

Some matters can only be settled on the day of the visit. The condition of the waterproof membrane, the presence of cracks at upstands and parapets, and the state of the fixings around rooftop units cannot be judged from a description or a photograph. The technician will decide whether a simple clearing and sealing job is enough or whether a larger section needs restoring. Pricing follows the work found on site: a maintenance visit is quoted at SAR 150–400 per visit, and any restoration is priced at SAR 50–150 per m² once the affected area has been measured. Schools should expect the final scope to be confirmed on site, not on paper.

To help the technician arrive prepared, the school should provide the roof plan or any drawings showing the drain positions, the dates of previous repairs, and a note of any areas that have leaked during rain. Access arrangements matter too: the site contact should confirm which roof sections are reachable safely, when classes are in session, and where the team should park and store equipment. Recording where water has pooled after a storm, and how long it stayed there, gives the technician a clear picture of the real problem. Clear information at the start usually means a shorter visit and a more accurate scope.

For schools, the larger jobs are planned for weekends and holidays.
