Before we start: what we know about 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.. The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

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

For companies in Dhahran, the most common roof rain leak emergency starts where the membrane meets a parapet, drain outlet or rooftop unit. Water tracks along these joints and reaches the ceilings below, often on a floor that is in use during the working day. Liquid roof waterproofing, priced at SAR 8–25 per m², is frequently chosen for flat roofs of this kind because it can be applied over a wide area and sealed around fixtures. Bitumen membrane, at SAR 15–35 per m², is another option where a heavier layer is needed, while spray foam at SAR 20–45 per m² can suit roofs where a seamless finish is preferred.

The local setting shapes how the repair should be approached. The centre of Dhahran sits about 16 m above sea level, so surface water drains across a fairly modest gradient, and blocked outlets can cause water to pool rather than run off. Dhahran is also about 5.9 km from the sea coast, which means the salty, humid air is a regular factor in how coatings age and where they fail. For this reason the repair team should check outlets and upstands before choosing a material, and should favour finishes that handle sun, salt air and standing water. Where the roof is shared with plant rooms or water tanks, tank internal coating at SAR 25–60 per m² may also be relevant to the wider scope of work.

Before the visit, ask the provider a few clear questions so the company knows what is being quoted. Confirm which area of roof is affected, whether the leak is above an occupied office, and whether any stored equipment or documents must be moved first. Ask for the price basis, such as cost per square metre, and whether crack injection at SAR 40–120 per metre is included for any cracked upstands. Agree how access to the roof will be arranged, and ask when the work can be carried out so that normal business is disrupted as little as possible.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
