Before we start: what we know about Qatif

The centre of Qatif sits about 5 m above sea level (SRTM open elevation data). Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Team note on Qatif: 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..

Roof rain leaks at schools in Qatif are handled with a clear first check, because the town's location shapes how water and moisture behave on a roof. The centre of Qatif sits about 5 m above sea level, and the town is about 2.5 km from the sea coast. Those two facts mean that salt-laden air can reach roof surfaces and fixings, so the technician looks first at the condition of the membrane edges, upstands and fixings where salt and wind may have worn the seal. Water entering close to a parapet or drain outlet is often the first sign, so those points are inspected before the open field of the roof is examined.

What is left to the site visit is the detail that only shows up when the roof is open and dry enough to read. The technician decides whether the leak needs a liquid roof waterproofing layer, a bitumen membrane, spray foam or boards of XPS insulation, because each option suits a different roof build-up and a different pattern of damage. Where the roof has cracks or joints that feed the leak, crack injection may be considered, and the length of the crack is measured on site rather than estimated from a phone call. Whether the leak also affects a water tank, a bathroom block or a basement below the roof is confirmed at the visit, since those areas use separate treatments such as tank internal coating or bathroom waterproofing.

Information that helps the technician is simple and quick to gather before arrival. Note the school's name, the building and the exact room where water appears, and say when the leak began and whether it follows rain, wind or heavy storms. Photographs of the ceiling stain, the roof surface and any visible cracks are very useful. Tell the technician whether the roof is flat or sloped, whether there is a previous waterproofing layer, and whether any work has been done before. Keeping access to the roof hatch clear and confirming a safe way up for the crew will also let the visit start without delay.

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