Roof & drain maintenance in Dhahran: the local context

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).

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..

Roof and drain maintenance for a restaurant in Dhahran begins with the drainage path, because the city's terrain shapes how water leaves a flat roof. The centre of Dhahran sits about 16 m above sea level, so the land carries rainwater inland and away from the coast rather than toward it. Technicians therefore check the outlets, scuppers and downpipes first, making sure each one is clear of grit, leaves and kitchen residue that could back water up onto the membrane during a heavy rain. A roof that looks sound from the ground can still hold standing water at a blocked outlet, and that is where leaks usually start.

Dhahran is also about 5.9 km from the sea coast, which is close enough that salt-laden air can settle on rooftop equipment, flashing and metal fixings over time. For this reason the first inspection pays attention to corrosion on exposed brackets, vent covers and extraction hood connections, and to any salt crust that may be breaking down sealants at joints. Because restaurants also vent heat, oil vapour and steam, the area around kitchen extraction points is checked for grease build-up that can stick to the surface and trap dust, a combination that wears waterproofing faster than the plain weather alone.

Several things are left to the site visit itself, since they depend on the building rather than the district. The exact condition of the membrane, the age and type of the roofing material, the slope of the deck, and whether there are cracks, blisters or ponding areas can only be judged once the technician is on the roof. Cost depends on the work found: a maintenance visit is typically SAR 150–400 per visit, while restoration of a damaged area is priced at SAR 50–150 per m², so the surveyed area and extent of repair are measured on the spot before any quote is given. Useful information to share in advance includes the roof area, how often the drains have been cleaned, where previous leaks appeared, and when the extraction system was last serviced, all of which help the technician arrive prepared and work efficiently.

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