Roof rain leak emergency in Baish: the local context

The centre of Baish sits about 84 m above sea level (SRTM open elevation data). Team note on Baish: 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..

Baish sits at about 84 m above sea level, which matters for a restaurant roof leak because the first question is simply where the water is getting in and whether it is still moving. Technicians start by checking the lowest affected area inside the kitchen or dining room, then tracing the stain upward to the roof penetration, since water often travels along a beam or duct before it shows. Restaurant roofs carry extra load from exhaust fans, grease hoods and rooftop units, so the seals around these fixtures are checked early. A quick check of the roof drains and any ponding water also tells the team whether the problem is a blocked outlet or a failed membrane.

Several things are left to the site visit because they cannot be judged from a description. The exact cause, the condition of the existing membrane, and whether the leak comes from a crack, a lifted flashing or a failed joint all need eyes on the roof. The technician will also decide the right system for the area, which might be a liquid roof waterproofing layer, a bitumen membrane or spray foam, and this depends on the slope, the age of the roof and how much of the surface is affected. Pricing for these options ranges from SAR 8–25 per m² for liquid roof waterproofing, SAR 15–35 per m² for bitumen membrane, and SAR 20–45 per m² for spray foam, but the final figure is only confirmed after measuring. Where a crack is the cause, crack injection is priced at SAR 40–120 per metre, again confirmed on site.

To help the technician arrive prepared, note when the leak first appeared, whether it worsens during rain, and which parts of the kitchen or storage area are affected. Photos of the ceiling stain and any water on the floor are useful, as are the dates of past roof work and any warranty papers. Please keep electrical equipment, food stock and cooking gear clear of the wet area, and move anything that could be damaged by dripping water. Clear access to the roof hatch or stairs saves time on the day, and a contact person who knows the restaurant's opening hours helps the team plan repairs around service.

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